Compared with the Navy, the Republic Air Force (including HNA) is a minor one from the "Science and Technology Revolution"

By the end of the Sino-Japanese East China Sea War, the progress of the Republic's Air Force mainly relied on early technical accumulation and had little to do with the research results of the Center for Physical Experimental.

At that time, the most eye-catching thing was the electric turbo accelerator used in the "Taihang" series of engines.

The electric turbo accelerator composed of "Longxiang Battery" and a superconducting motor is also called "electric turbocharger". It is mainly used to increase the air flow of the turbofan engine, which is equivalent to adding a first-level low-pressure turbine to the turbofan engine to achieve the purpose of improving the combustion efficiency of fuel and increasing the thrust of the engine without increasing fuel consumption.

Electric turbo accelerators gave birth to j-10b, j---11b and j-13b.

"Power" has always been the biggest obstacle to limiting the combat effectiveness of the Republic's Air Force.

At the beginning of the 211th century, the main "power" of the Republic's Air Force also came from Russia. At the beginning, exports were once blocked because of the use of Russian-made rd-33 engines on the FC-11 fighter jet sold to Pakistan. Affected by this incident, the Republic increased its investment in the development of aircraft engines.

Based on al-31f, the Republic has developed the "Taihang 0 Motivation with all intellectual property rights.

There are 2 models of the "Taihang" engine that combines electric turboaccelerators, namely "Taihang 0-11" and "Taihang 0-2, among which, "Taihang 1c-1" is the standard equipment for j-10b, j-111 and j-13, and "Taihang 1c-2j-11b and j-13b: standard equipment.

The Republic Air Force performed outstandingly in the Fourth India-Pakistan War, defeating the strong enemy in the East China Sea War, and three types of fighter jets equipped with the "Taihang" series of engines were the first to be successful.

Really "enjoy" the research results of the Physical Experiment Center or the fourth-generation fighter jet in the Republic.

The j-14-shaped function defeated the large early warning aircraft of the Japanese Air Self-Defense Force in the East China Sea War. Reversing the passive situation is not unrelated to the "active electromagnetic interference device".

It can be said that the development process of the .j-14 is a lesson plan for the Republic Air Force to "make up for shortcomings".

When the development project was launched, the Air Force had very high local requirements and very weak technical reserves, so the development work was suspended several times and was almost forced to dismount.

It was not until 2014 that the development work of Taihang 1 made breakthrough progress. The development work of j-14 was on track.

Subsequently, the second phase of the Physical Experiment Center was launched. Polymer composite materials were included in the main research topics. The development of j-14 began to accelerate.

During the first enclave in early 20166, there were still many problems that needed to be solved by j-1 modeling machine.

According to the plan submitted by the Air Force, the service time of J-14 was postponed from June 20177 to December 20177, mainly because of the large number of new technologies and new materials, resulting in too large design modifications in the finalization stage.

It can be seen that what the Air Force wants is advanced fighter jets that are comparable to the F-22, rather than "half-baked goods".

Like the j-14, the development of the j-15 fighter as a low-end match is also very difficult.

Because it is equipped with only one engine, the thrust of the "Taihang 15" for the J-15 must be increased by 25% compared with the "Taihang 1" in order to make the J-15 have maneuverability not inferior to that of the third-generation and a half-air fighter. Because the fuselage is smaller, the electronic equipment developed for the J-115 has higher integration and greater development difficulty. Because it is to be used as an aircraft carrier, the basic models of the J-15 are 2, not one; the carrier-based aircraft models have higher requirements for corrosion protection, fuselage strength, landing gear strength, combat radius, and combat purposes, and the development difficulty is also greater.

Compared with j-14, j-15 adopts more new technologies. When designing, the impact of new materials is taken into account. In the latest design book, the main bearing parts of j-15 are made of high-strength alloys, the main structure of the wing is made of composite materials, and the wing and fuselage skin are shaped by polymer composite materials at one time; the fire control radar adopts the "hy166" type active phased array multi-function radar that was finalized at the end of 20166, and the integration degree is 50% higher than j-1 "hy11. When the volume is reduced by 1/3, all performances exceed "hy14

From the start of the project in 2010 to the end of 2016, the Air Force invested 37.6 billion yuan in research funds for J-15, and the basic research costs alone exceeded 210! Although the research funds for J-15 are nothing compared to the F-35, this is not a small amount of money for the not-wealthy Republic Air Force.

Fortunately, many research results of j-14 can be used on j-115.

In addition to the huge research funding of the Republic's Air Force, Pakistan, which participated in the development work, has also invested billions of dollars.

According to the Air Force's "Long-term Plan", after the J-115 is in service, it will gradually replace the J-7, J-8, J-10 and Q-5 series fighter jets within 1, becoming the main medium-sized fighter jets of the Republic's Air Force. HNA is also preparing to replace the J-7, J-8, J-10 and Q-5 with J-15, and set the J-15 as a standard aircraft carrier aircraft. Including the 150, J-15 promised to purchase, the output of J-15 will definitely be above 2,200. If you can gain something in the international market, the output of J-15 will not be less than 2,500, and may exceed 3,000, becoming the fourth-generation fighter jet with production output only after the F-35.

However, the first one to serve was not the air force type j-15, but the naval ship-based type j-15.

When the "Republic" aircraft carrier was launched, J-10b and J-13b were allowed to fly together, just to show off the foreign military officers invited to attend the ceremony. As long as J-15 is

: The first flight will be available in the mid-2018. At this time, the "Republic">sea test work before service.

In addition to fighter jets, the replacement of other aircraft models has also begun.

The next generation of early warning aircraft and tanker ground-mounted aircraft are both developing "y-14 electric large transport aircraft, and the y-14 is directly related to the large trunk passenger aircraft flying on board.

The key technology of fully electric large transport aircraft is "composite battery plastic surgery technology".

Unlike the Navy and Army equipment, the space on the aircraft is more precious and the weight restrictions are stricter. When developing the J-14, in order to encourage designers to reduce the weight as much as possible, the Air Force threw out the bait of "rewarding 1 month's salary for every kilogram of lighter", which resulted in a full 44 kilograms of j-1's empty weight reduction!

Obviously, the "Longxiang Battery" cannot be installed on the plane at will as it is on a warship.

According to the design plan proposed by Shangfei, the composite battery must be integrated into the wings and tail of the aircraft, and the "ineffective space" on the aircraft should be used as much as possible to avoid invading the "effective space" in the cabin. In order to reduce weight, the composite battery must be integrated with the load-bearing structure.

Because the y-14 is a military transport aircraft and can use "Longxiang Battery", the development difficulty is slightly lower.

At the end of 20166, the first y-14 prototype (and the only prototype) made its first flight. In the subsequent test flight, it achieved a flight result of 12,740, a maximum flight speed of 970 kilometers per hour, a minimum flight speed of 210 kilometers per hour, a maximum load capacity of 65, a maximum load capacity range of kilometers, a range of 7,500 kilometers when load capacity of 2c, and an unload capacity of 1c,500 kilometers.

All data meet the requirements put forward by the Air Force.

Like the problems faced by the Navy, if y-14 wants to mass production, it must solve the cost problem.

Only one prototype was built, because the 34 "Longxiang Battery" equipped with it made its cost as high as 7.5 billion yuan. Not to mention the Republic Air Force, even the US Air Force would not be able to buy a land transport aircraft more expensive than gold.

The production and price of composite batteries also have a negative impact on civil aviation.

Because the production of "Longxiang Battery" has not increased, Ji Youguo has never approved the launch of composite batteries (from Level 1, the energy storage rate of 3,600 kJ/kg for each increase in first-level energy storage rate. The energy output rate of 28,800/kilojoules/kilogram is a 8-level composite battery) to the civil market. It is a 2-level composite battery for electric vehicles, and a 3-level composite battery for high-end civilian products. Only some foreign trade military products use composite batteries.

Although the Physical Experimental Center has developed a 12-level composite battery, output is more important than performance.

According to the design plan of the upper enclave, when optimizing aerodynamic design and adopting civil standards, a fully electric large trunk aircraft with a range of more than 0,000 kilometers, carrying more than 300 passengers, and carrying more than 70 loads only requires a 6-level composite battery. The problem is that the price of a 6-level composite battery is not cheap either.

There is no doubt that all-electric regional passenger aircraft and trunk passenger aircraft will have a revolutionary impact on the aviation market.

The design has been completed and the branch passenger aircraft that is manufacturing the first prototype aircraft has brought about a magnitude 12 earthquake to the international aviation manufacturing and international air transport industries.

According to the data released by Shangfei, the operating cost of czz1 regional passenger aircraft is only RMB 1 ton-kilometer. According to the calculation of 2,500 kilometers, the flight cost of one trip is only RMB 7,000 (about US$400), which is only 35% of the b-737-800 regional passenger aircraft and 33% of the a-320-66c0 regional passenger aircraft. Based on 150 and the full occupancy rate is 80%, the one-way ticket price can be completely reduced to less than RMB 1!

Although the unit price of the basic model of the czz1 launched on the flight is as high as 8.7 billion yuan, which is 1 times that of the b-737-800 and 177 times that of the a-320-600, for airlines around the world, the cz-011 regional passenger plane has an unparalleled "charm".

Airlines consider not only purchasing prices, but also operating expenses and maintenance expenses.

With all-electric propulsion, czz1 not only has a much lower operating expense than competitors, but also has maintenance expenses of only about 30% of competitors.

According to the 25-year flight of a regional passenger plane and a total flight time of 80,000 hours, the life of the cz-011 is only for the competitors.

For airlines affected by the financial crisis, cz-011 has become a "golden medicine" for "resurrecting the dead".

That's right, before the finalization, czz1's official order and intention order exceeded 2,000!

In the words of Boeing's president, the emergence of cz-c11 will cause Boeing to face unprecedented challenges!

In the report submitted by Shangfei to the central government, it was clearly mentioned that if the production of composite batteries can be increased and the performance of 6-level composite batteries on Czz1 will be improved by at least 20%. Even if the selling price is increased by 25%, the cost-effectiveness will exceed all competitors.

Relevant departments of the State Council also submitted a report.

If the production of 6- and 8-level composite batteries can be increased by 1 times and the mass production of 12-level composite batteries can be achieved, the fully electric large trunk passenger aircraft will have unparalleled competitiveness in the international market. As long as the United States and Europe cannot develop related products that are comparable to 6-level composite batteries within 0 years, Boeing and Airbus will definitely go bankrupt.

The question is, is it so easy to increase battery production?
