About the Blavatnik Family Foundation The Blavatnik Family Foundation is an active supporter of world-renowned educational, scientific, cultural, and charitable institutions in the United States, the United Kingdom, Israel, and throughout the world.

The Foundation is headed by Sir Leonard Blavatnik, a global industrialist and philanthropist and the founder and chairman of Access Industries, a privately held industrial group based in the U. See more at www. One of the only three in the whole world and MediaTek are apparently not in the same league as those from America. In the manufacturing sector, where the design on paper is built into real stuff that you can use, the sole leading country is Taiwan, the only country that has had the technological capability to touch anything smaller than 7 nm process, while other countries still struggle with poor yield rates, a critical problem most likely caused by their lower capability in a fundamental science — materials engineering.

The technological gap between TSMC and all the other IC manufacturers from any parts of the globe only becomes more obvious and much bigger as computer technology progresses into smaller process year after year.

What we know is this chip is designed for HPC high performance computing , not for the consumer markets. Taiwan cares a lot about every move of TSMC. When TSMC was about to decide where to locate its 3 nm fabs and when everyone was guessing, ITRI commented that TSMC would be much more careful choosing the location out of the whole world for its 3 nm fabs than for, say, 7 nm or 5 nm fabs, because 3 nm was on a completely different level as 3 nm was only a step away from the field of QC Quantum Computing , the ultimate area of computer technology.

TSMC is in. High-entropy alloys have high hardness, and therefore will benefit industries that appreciate such a property. In the image above is a Challenger 2, a British main battle tank employing the 2nd generation of chobham armour. Chobham armour is developed by America and has been the known hardest armour for any battle vehicles — at HV.

Various high-entropy alloys that can be used in the defense industry have been reported to have greater hardness. High-entropy alloys are materials born to survive in extreme environment in that they are not only highly resistant to heat and irradiation, but also to corrosion and pressure.

The Venera 13, a probe landing on Venus in , managed to maintain operational for roughly minutes, and then died. There have been various light-weighted and hence ideal as structural materials of aerospace vehicles high-entropy alloys reported to show potential to survive in such an alien and extreme environment.

But HY is too heavy to have applications in aerospace. The Germans most likely developed HY themselves, but since Americans are the inventor and patent holder of the HY series materials, Germany still has to pay royalty to America. In the picture above is an experimental fast breeder reactor under construction, and the big metal hollow cylinder in the middle of the pic is its core.

Fast breeder reactors are a type of the 4th generation nuclear reactor. The research team believes this alloy can be ideal for building the interiors of magnetic fusion reactors. You can take a brief look at this study here[29] if you are interested.

High-entropy alloys are superconductors. Such an extremely low level of electrical resistance triggers diamagnetism to happen. High-entropy alloys have been discovered to maintain low kinetic energy internally even at higher temperatures as long as pressurization is applied to them.

A research team from Tokyo Metropolitan University[30] has found the temperatures for their superconductors to activate diamagnetism rise simply owing to addition of layered high-entropy alloys. This is incredible, that simply adding one or two layers of something could directly cause the temperature triggering diamagnetism to rise.

High-entropy superconductors have attractive magnetic properties, and are considered candidate materials for development of more advanced magnetic applications. When it comes to magnetic materials, one important quality to look for is the strength of the magnetic fields that the materials are capable of forming. Human technology based on magnetic superconductors relies greatly on the strength of the formed magnetic fields, such as maglev systems and particle accelerators in that they need a powerful magnetic field to reach high speed.

The Earth itself is a giant magnet, generating 0. The famous Large Hadron Collider LHC , a particle accelerator located in Europe, crossing the border between France and Switzerland, producing antimatter by having high-speed particles collide with each other.

This is because of a fundamental mechanical property of high-entropy alloys: very low density. Sure, high-entropy alloys may have high strength, high hardness, great resistance to heat and pressure, and can survive in an environment that is dangerously corrosive and has deadly volume of irradiation that can easily destroy any other metals, but none of these will matter if high-entropy alloys are expensive materials.

Us humans have never lacked of new materials that exhibit one or even more favourable properties that high-entropy alloys have, yet most of these materials never go into industry from laboratory stage due to one simple reason: high costs. Nobody is going to use a material — no matter how good it is — if at the end of the day the profit shrinks because of using it, or simply because the costs are too high for the budget to support.

However, thanks to having very low density, high-entropy alloys are much cheaper than their non-high-entropy counterparts. What does this mean? It means gold money. High-entropy alloys and high-entropy materials have a wide range of applications, from industries that require parts and components to work in extreme environment, such as aerospace, automobile, defense, energy, to industries that demand high precision, such as machining and semiconductor, and even extend to what people see in daily life, such as culinary appliances, construction and sports.

These will all bring economic benefit to Taiwan, the national origin of high-entropy materials. He made Taiwan become one of the handful countries in the world - and one of the two in Asia - that could independently develop turbofan engines, which still remains the same today. He was productive and had won many prizes.

On May 13, , his body and separated right arm were found lying on the ground near the building of the department of materials engineering by a student who was about to head home from NCKU in the evening[32], the university he had taught at for years.

He developed depression in his later years and took his own life that day, jumping to his death. These blades have been used in the F ever since. Four pictures of the Indigenous Defense Fighter exhibiting 2 different kinds of painting - airshow and regular.

Hence the IDF is a 4th gen fighter jet based on US definition, a 3rd gen fighter jet based on Russia definition, and a 2nd gen one according to us.

The first flight is scheduled in June, Development of the XAT-5 means a lot to the Taiwanese aerospace industry for it is the first time that Taiwan has completely by itself been in charge of the structural and aerodynamic design of a manned high-performance military aircraft.

So far, Taiwan and Japan have been the only 2 countries that can independently develop manned military aircraft 4th generation and after in Asia. Not only that, Leonardo S. A developer of the M had also done its best to please Taiwan as Leonardo S.

A agreed all the terms that Taiwan proposed including locally-manufacturing for the core parts, not just assembly , along with offering a very nice price almost dirt-cheap for the M itself, much cheaper than how much the same aircraft was sold for to Poland, Singapore and Israel.

This was because Leonardo S. Anyway, at the end of the day, quite unfortunately for Leonardo S. A that despite its having been pleasing this potential buyer in every way possible, Taiwan still decided to domestically develop what it needed - so there it is, the XAT In comparison with the M, the XAT-5 has clearly more characteristics of a fighter jet in that the XAT-5 is longer, thinner, slimmer, sharper and more pointy like a spear while the M is shorter, thicker, fatter and rounder, which already makes a difference between them - the XAT-5 is supersonic while the M is not.

Contrasting with the XAT-5, the M can only reach 0. September 23, , the first fresh-off-the-production-line XAT-5 was unveiled. First flight scheduled for June One example is Turkey. Turkey was willing to pay a large sum of money for Taiwan to transfer technology of turbofan engines.

The T91 Assault Rifle. The thrust vectoring nozzle requires very advanced material technology as the nozzle has to tolerate heat even higher than that in the combustion chamber of the engine. This thing has always been very mystic ever since the very beginning of the spread of the rumour regarding some Taiwanese scientists who worked for the Government of the United States in the defense department developing stealth technology coming back in Taiwan and joining the NCSIST.

No one can say for sure. As you can see, it to a degree resembles the design of the Boeing X picture below as the weapon bays are put aside for the inlet to be right in the middle beneath the fuselage, yet unlike the Boeing X, the ADF will be powered by two engines this is officially confirmed , just like the F Based on the reports so far, the engines will use turbine blades made of High-Entropy Superalloys, superior to the last generation of nickel-based single-crystal superalloys, and be equipped with the thrust vectoring nozzle mentioned above, all homegrown.

The Boeing X, a 5th-gen combat aircraft. This engine above is the JGE, most famously known for powering the F-5 fighter jet family. Taiwan used to be a main F-5 operator, but now these jets are considered outdated by the ROC military and only 23 units of them are currently in service in Taiwan. Instead of scrapping the JGE, the military has decided to make better use of it — they want to reverse-engineer it and develop a more refined version, with new materials and technology.

Other people say maybe the new J85 is for a new UAV, which actually sounds more convincing to me. A fighter jet usually has - 1, modules depending on how large the jet is, and thus the peak power of the whole AESA radar is summed up at 9. Apparently this was made before the ROC Air Force officially confirmed a part of the specification of the jet because in this design, the jet only has one engine whereas the military has said the jet will be twin-engine.

Reliable sources said the homegrown next-gen fighters may have delta wings or a variant of delta wings. Delta-wing planes that are currently or were once in service, for example, the FXL the one highlighted in the pic in the top-left corner , concord top-right , and Eurofighter Typhoon bottom. The two images above are from a video recording the testing of the F The testing as well as the development of the engine was done at AIDC, in the s.

The TWR of a turbofan engine is highly correlated with the temperature at turbine inlet, the higher the temperature, the higher the TWR. There are two ways to achieve a high temperature at inlet of the turbine — one is to use aerodynamic mechanism of the engine itself to cool down the blades to increase heat durability, which is a technology that the US excels at, with the UK being a remote second and every other country far behind, the other is to build the blades with more advanced materials superalloys , which is what Japan excels at, leaving both the US and Europe far behind.

Turbofan engine F, the F is equipped with two of them. The weapon bay of the F The F has a TWR of 7. The heat capability of a turbine blade is three things combined: the materials of the blade, the cooling system of the blade, and the TBC thermal barrier coating on the blade. This is not a bowl of milk or white gel. The bondcoat layer is in charge of preventing the base material of the blade from becoming corroded and oxidised.

Research has found high-entropy materials to be promising for more advanced bondcoat applications. Hence the Inconel Alloy H is widely adopted as the material to build the critical equipment - chemical reactors, used in petroleum, energy, and many other heavy industries. A petroleum chemical reactor under construction. The picture above is not hairs but carbon fibers.

Carbon fibers, as the name suggests, are fibers made of carbon. Carbon fibers can be classified as three types — low-end, mid-end and high-end. How we determine the types of carbon fibers is by measuring their modulus unit: GPa , the higher the modulus, the higher the class. Low- and mid-end carbon fibers range between GPa and GPa respectively, while high-end carbon fibers are well above GPa.

The production of carbon fibers is very technically demanding and as a result only 5 nations are capable of manufacturing them. Most carbon fibers manufacturers in the world aim at low- and mid-end markets, producing carbon fibers that are appreciated by sport and automobile industries. On the contrary, high-end carbon fibers, being strategic materials as they are basically used exclusively in aviation, aerospace and military — for example, the making of advanced nuclear warheads and hypersonic aircraft missiles flying at above 5 Mach included , are controlled items worldwide, but the good news is high-end carbon fibers are extremely difficult to produce.

Other than the Japanese, the Taiwanese are the other people that have the know-how regarding how to produce high-end carbon fibers. This is a Lamborghini car named Sesto Elemento, one of the most expensive automobiles made of carbon fibers.

Half of a Boeing is made of high-end carbon fibers. Wankel engines are favourable in many aspects in that they can produce large power even at a small size, take the engine here for instance, it displaces c.

Wankel engines are difficult to develop due to high demand for materials and precision of parts, particularly the latter. Taiwan is a different case as Taiwan started all from scratch. A powered exoskeleton developed by Raytheon. Many countries have plans to develop military powered exoskeletons.

Nevertheless, thus far only a few of them have been able to successfully develop small yet powerful engines, the most crucial technology that developing a powered exoskeleton requires. Instead of using an engine, it uses a motor as the supply of power, causing its slowness and generally weaker bearing for force, but it should still be fine because HAL is for medical use, not military.

The image above is a product from AeroJones Aviation, a Taiwanese company specialising in light sport aircraft development except the engine. The Diamond DA20, a famous European light sport aircraft that has variant models, of which some are powered by Wankel engines.

It hit a fishing boat. A single fishing boat, in a large open area where no other ships were seen. The missile could have gone straight into the ocean since there was no set target for it as it was launched accidentally , yet, it hit a fishing boat.

It would have been a different story had what was hit been a military ship. A typical RCS diagram. Dangerous, fast, light and stealthy — raptors. The Kuang Hua VI-Class Missile Boat, a stealth ship from the Tuo Chiang warship family, which the radar system of a fishing boat failed to detect and resulted in a collision accident in [37].

The prototype of this ship was launched in Model of the diesel submarine planned to build from to The fleet will comprise 8 submarines, displacing 3, tons each. The lead ship is scheduled to enter commission in , and for the entire fleet. Each of the submarines will cost 1. The most difficult part about building a modern submarine - if not taking its internal design into consideration - is the frontal part of the submarine in that the frontal part of a submarine has to be extremely precise in terms of its shape, calculated by the supercomputer in order to distribute water pressure surgically evenly, or the sea water will either break in the submarine starting from the frontal part, or slowly lead the submarine to deformation as time goes by.

To achieve such precisely even pressure distribution, sophisticated welding technology is required as one tiny air bubble caused by unsophisticated welding in the steel used to build the frontal part of a submarine, is enough to ruin the entire pressure distribution setting.

Taiwan however, is one non-G7 member that has successfully developed this technology, which I think is called HWD Welding not sure though. Lithium batteries are a very powerful and efficient independent source of electricity, hence are ideal for being used as the electric propulsion system of the diesel engines in submarines - if only they were not that dangerous, as they can become quite unstable and readily to burn and then of course, explode at any moment when not controlled well.

The other two propulsion systems, in comparison with lithium batteries, are inferior except they're a lot safer, having been put to use for a long history. The AIP has very limited power, causing the submarine to move extremely slowly, and unlike batteries that are quiet for all eternity, a working AIP system has a lot of noises while sound waves can travel for a long distance in water, which in return reduces survival rates of the submarine.

As to lead-acid batteries, while they generate a lot more energy than the AIP so the vehicle can be faster , they are quite heavy, significantly adding extra weight to the vehicle, and like lithium batteries, they too do explode but a lot easier to prevent than infamous lithium batteries.

So diesel submarines usually have both the AIP and lead-acid batteries working together, with the number of lead-acid batteries cut in half, thus the vehicle will be faster than when exclusively using the AIP, at the same time being lighter than when only using lead-acid batteries to a full number , Japanese submarines being a very good example.

Taiwan, Japan and Germany are the 3 best known countries for advanced battery technology. The submarine will adopt an X-shape tail and a front that has a curved top but a flat bottom. This kind of design is unusual as only a few submarines have similar appearance, but this design has been proven to be superb for stealth.

The flat bottom of the front is for housing a much larger and more advanced sonar system than one that a submarine having a curved bottom would use. Spain is traditionally known as a country having high naval strength. The Spanish Isaac Peral class submarines adopt a design that is more conservative and common, because as you can see, the front of the Isaac Peral class submarine is curved both top and bottom, and the tail is cross-shaped.

This design has been proven to be very reliable. The steel has been tested and reported to be able to sustain hydrostatic pressure equaling that at metres underwater. A submarine base is a navy base specifically designed for submarines for stealth purpose and offers the submarines it houses a quick access to deepwater.

A couple of nautical miles away from the east coast of Taiwan lie two main trenches on the west part of the Pacific, both easily more than five thousand metres deep. What can be better? From a strategic point of view, Taiwan is sort of lucky to be geographically located in a place that not only can directly control the maritime trade routes between East Asia and other parts of the world, but is also guaranteed direct access to deep water the Pacific Ocean.

Sure, the PLN is one of the strongest navies in the world, but being unable to access the Pacific Ocean privately would always make it a handicapped force no matter how strong it is. TECO is one of the most major home appliance brands based in Taiwan, offering wide selection of washing machines, air conditioners, refrigerators, TV and etc for ordinary consumers like you and me, but few people - even the Taiwanese themselves - know that TECO has never been just a company that sells home appliances in the first place.

TECO has been, in nature and since the very beginning, a corporation that designs and develops heavy electric equipment for the energy and various other heavy industries, including shipbuilding, several decades before stepping into the home appliance markets. A large motor developed by TECO for the shipbuilding and energy industries. TECO Texas branch and some of the employees. The amphibious transport dock bigger one currently under development, scheduled to be in commission in We need amphibious transport docks because we have to guard our islands in South China Sea from threats from countries such as Vietnam and China, and amphibious transport docks help project the land forces tanks, mainly from Taiwan onto any of our other islands.

The Sea Oryx Missile System. The missile frigates planned to build from to , each displacing 5, tons. The fleet will comprise 15 missile frigates. Taiwan currently has 22 frigates and we want more. The JS Izumo. Tian-Gong III Anti-Tactical Ballistic Missile, with an operational range of km and an interception altitude of 70 km enhanced version , travelling at a speed more than 4 times faster than the sound the general consensus is 5—7 Mach.

Also, hot launch is much faster, and has smaller RT Reaction Time , increasing the survival rates of the ship. Let me tell you how many countries have their own homegrown seaborne hot vertical launching system as of late Taiwan, America and France. Military is a science, not a religion where faith and belief work, so any claims without evidence are really only claims. The HF2E is land-based, but it can also be seaborne, launched by water vehicles.

It was in that the HF2E had been for the first time officially confirmed by the Government to have been deployed sources have said the estimated number of unit lies between and 1, Other than these, everything else about this missile has never been known to the public.

This is um … the Yun-Feng Cruise Missile. The Yun-Feng Cruise Missile is supersonic 4—5 Mach , propelled by a ramjet engine, maximum operational range 2, km 1, km minimum. Initially, it was about to go into production in , but in order to befriend China, Ying-Jeou Ma cancelled the production project.

The eleven images above are fetched from a video filming the most recent launch test December, of a new missile developed by NCSIST I know I can simply put the video here, but I prefer pictures for consistency. I personally think this is a new type of Tian-Gong anti-tactical ballistic missile, based on the fact that my ATC colleagues in Taiwan told me they were informed of airspace closure of that area that day, with the height for restriction being unlimited.

In January , the missile launch test in December last year has been confirmed to be a new type of the Tian-Gong missile.

The picture here is a Tian-Gong II missile. The displacement of the largest aircraft carrier in the world thus far is , tons. I know this one looks like a photoshoped picture, but no, it is real-life. I saw the ship once, the year it was built, and I was completely in awe.

MV Blue Marlin can also do this. An Ocean Alexander yacht. Two pictures of the interior of an Ocean Alexander yacht. The Kestrel Anti-armour Rocket, a homegrown rocket that can penetrate most armour vehicles including amphibious tanks, with the only exception being main battle tanks of the third generation.

This convenient and light-weighted individual weapon was developed back in the s when the PLA still had no possibility of being technologically capable of landing any main battle tanks on shore of Taiwan for lacking vessels that could transport such heavy armour vehicles, but things had changed ever since. The soldier on the right is carrying an FGM Javelin, you can see how much bigger it is in comparison with the Kestrel anti-armour rocket.

The homegrown CM Black Bear middle, with a tank gun as you can see. The tank gun is also homegrown and two CM Cloud Leopards. The Cloud Leopard has been in production while a newer type of the Black Bear that features more advanced defense technology and design is being developed. The Black Bear in this picture is the older type. A closer look at the CM Cloud Leopard.

Its main armament is a 30 mm chain gun. The Cloud Leopard had a scandal, that its prototype completely met the designated performance without any problems, yet when went into production with more mature technology and design, the first couple of models of the Cloud Leopards had serious defects in that their chassis - supposed to be one of the strongest parts for hardness - and some other parts of the vehicle, cracked.

It turned out that the manufacturer in charge of producing these parts used steel from China for dirt-cheap costs to replace the expensive yet high-quality steel produced by CSC a Taiwanese steel company. The people responsible ended up in jail for it was illegal. Headquarter of CSC, Kaohsiung. CSC is one of the very handful steel companies in the world that can produce A, a superalloy that is widely used to build components of jet engines.

Its future design is to be a self-propelled mm mortar. Two pictures of the Cloud Leopard II being tested in the field. Again, the chassis and suspension system have been completely redesigned because the military plans to equip it with larger guns.

In the image above, the one closest to the camera is an unarmed type II, the others are type I equipped with chain guns. The largest gun that Taiwan has developed independently, a homegrown mm howitzer, using a truck as the vessel.

The ROC military has said they have a plan for equipping type III of the Cloud Leopard with mm howitzers — but, the gun will be smaller than the one in the picture here, of course. Hence, the AVDC is planning to develop new tanks equipped with homegrown mm tank guns along with more modern engines if the budget agrees. The M1 Abrams. This engine has displacement of 2. By the way, so far China is still incapable of independently developing any diesel engines. Special steel is nothing like the conventional steel used in construction or regular civilian fields.

The barrel of a tank gun can only be made of ESR steel a kind of special steel that can endure — MPa of explosive pressure. It really is only a matter of budget of how much money the army is willing to put to investing in a homegrown main battle tank.

The Leopard II, with a turbocharged diesel engine displacing 48 liters, 1, horsepower maximum. The Formosat-5, the recently launched Taiwanese optical remote sensing satellite, completely homegrown, with high definition imaging capabilities that despite the Formosat-5 travels at an altitude - km above the surface of the Earth, it can see clearly anything that has 2 metres of length on the ground.

Only a handful of countries can domestically design and build optical remote sensing satellite. In fact, among the 12 countries that possess the ability to launch satellites - the UK, America, France, Russia, Japan, Israel, Ukraine, South Korea, India, China, Iran and North Korea, only 5 of them can independently develop optical remote sensing satellites providing high definition imagining functions.

The HTTP-3 rocket, developed by a small team mostly made up of college students. The HTTP-3 is a hybrid-propellant rocket, technologically more advanced than the solid-propellant rocket or liquid-propellant rocket. The HTTP-3 is completely homegrown, including the engine that has 4 tons of maximum thrust. The HTTP-3 is scheduled to launch in Taiwan between and , and will carry a satellite America has no excuse to stick its nose into this as the entire plan isn't governmental.

The HTTP-3 team, the whole team. In the first 15 years, we have developed crucial rocket technology and been able to design satellites with technological assistence of other countries and core parts from them. From to , the second part of the programme, we have come to be able to independently develop advanced satellites, all homegrown. This rocket has kg of payload, originally scheduled to launch in Taitung on the 27th December, but has been postponed due to concern raised from the locals.

This company partially works with the government and has deep intellectual connections with some of the most prestigious Taiwanese academies. The Brazilian rocket VLS-1, kg of payload. The picture above was shot on the campus of Academia Sinica, the national academy of the country. According to theory of relativity, this leads to potential development of very powerful laser. Now scientists have proposed a different method to propel solar sails - by using artificial source of radiation pressure, ideally laser - they mean the very powerful kind.

Theoretically, a solar sail propelled by a couple of GW of laser would be able to reach one fifth of the speed of light, taking 25 mins to reach Mars from the Earth.

As the national academy, Academia Sinica naturally grants membership almost only to those of the best reputation academically.
