The third generation fighter with independent intellectual property rights in our country is

The third-generation aircraft that our country now has are annihilated.

10. J10. 1. Su-27, Su-30 and quasi-third-generation Thunder Dragons, plus those who have appeared but have not been made public.

Ten. Fifth, the J-16 is a third-generation fighter. Among them, the Su-27 and Su-30 were directly imported into Russia, J.

Ten. 1. J-10.

Fifth, the J-16 is not an imitation of the Su-27, or an imitation of the Su-30, Su-33, although these imitation models, including the engine, all components can be produced in China, and the performance also exceeds the prototype, but the name is not justified. Then there is only the quasi-third generation of the Thunder Dragon and J 10, the Thunder Dragon is upgraded and improved on the basis of the original Super Seven, that is, the original Sabre plan, and later China and the United States turned their faces, ** embargo, China and Pakistan finally designed the Thunder Dragon, but the engine of the Thunder Dragon is still used in the Russian RD39, recently there is news that China's push has been successful, if the news is true, then the Thunder Dragon is a third-generation aircraft with independent intellectual property rights in China. Look at the J-10 again, the J-10 does not need me to introduce, the problem is still the engine, this situation will change after the WS10 matures, especially the J-10B, which must have 100% independent intellectual property rights.

China's third-generation fighter with independent intellectual property rights is the J-10, which is divided into two models: J-10A and J-10B, J-10A is an air superiority fighter, and J-10B is a multi-functional fighter, which strengthens over-the-horizon precision strikes on the ground and sea.

The most typical is the J-10, although there are AL-31F engines imported from Russia, but the whole process from the design of the aircraft to the service is China's independence. In addition to the engine, the aircraft's avionics equipment and mounted missiles are all domestically produced. The characteristics of the Thunder Dragon fighter may be a third-generation aircraft, which are somewhat euphemistic.

The J-11 began to imitate the Su-27, although now it may be replaced with domestic avionics and WS-10 engines, but the aerodynamic layout still continues the Soviet-style style.

To be precise, it should be the J-10B, because the previous model used a Russian engine, and this model is a domestic engine.

J-10, but it is still an engine imported from Russia, and China is a short board in this convenience.

J-10, J-10A, J-10B, J-11A, J-11B, Flying Leopard series fighters, and the J-15 under developmentTo a greater or lesser extent, the fighters developed by China have been imported from foreign countries. The engines of Chinese fighters are not powerful, and they must be imported from the big brother of Russia.

J-10, in fact, it does not completely own independent intellectual property rights.

For the first time, China developed a large passenger aircraft with independent intellectual property rights in accordance with international standards, and the wheel is the C919 aircraft.

The C919 aircraft, the full name of COMAC919, is a large jet civil aircraft developed by China in accordance with international civil aviation regulations and with independent intellectual property rights, with 158-168 seats and a range of 4075-5555 kilometers. It has completed the project demonstration, feasibility demonstration and pre-development stage work, and transferred to the project development stage. On November 2, 2015, it was completed.

The performance is comparable to that of the international new generation of mainstream single-aisle passenger aircraft. It successfully made its maiden flight on May 5, 2017.

The C919 passenger aircraft adopts advanced aviation technology and materials, such as composite materials, advanced power systems, advanced control systems and avionics systems, etc., with high safety and economic performance. The development time and investment of the C919 passenger aircraft are very long, lasting 9 years. The successful first flight of the C919 passenger aircraft on May 5, 2017 marks an important step forward for China in the field of aviation and is of great strategic significance.

C919 Qualifying History:

On May 14, 2022, the first flight test of the first C919 large aircraft to be delivered to the first user by COMAC was successfully completed. On July 25, six domestic large passenger aircraft C919 test aircraft successfully completed all test flight tasks. On August 1, COMAC announced that the domestic large aircraft C919 completed the certification test flight.

On September 7, the domestic large aircraft C919 flew to Hefei Xinqiao Airport for the first time.

On September 13, the C919 domestic large aircraft flew to Beijing Capital International Airport for the first time, and on September 29, the C919 aircraft was awarded the type certificate. In October, the State Administration for Market Regulation officially approved the establishment of the National Commercial Aircraft Industry Metrology and Testing Center relying on Commercial Aircraft Corporation of China. On December 9, the world's first C919 aircraft numbered B-919A was officially delivered to China Eastern Airlines.

On December 14, Ziguang Guowei said that it would provide an airborne total random line exchange chip for network communication for domestic C919 aircraft. On December 26, the world's first C919 domestic large aircraft started a 100-hour verification flight journey. On January 1, 2023, China Eastern Airlines' world's first C919 large passenger aircraft flew a test flight.

In February, the C919 successfully completed 100 hours of verification flight. On May 28, 2023, the domestic large aircraft C919 ushered in its first commercial flight.

Question D emphasizes the role of independent innovation capability in international competition, while independent innovation emphasizes the economy and science and technology, so the correct answer is incorrect.

When the J-10 fighter accelerates from the ground and takes off, the altitude increases, the gravitational potential energy increases, the speed becomes faster and faster, and the kinetic energy increases;

So the answer is: get bigger, get bigger

Get bigger, get bigger.

This question examines the magnitude change of kinetic energy and potential energy, the energy that an object has due to motion is called kinetic energy, the greater the mass, the speed.

The greater the degree of genus, the greater the kinetic energy; The energy that an object has due to being lifted is called gravitational potential energy, and the greater the mass and the higher the height, the greater the gravitational potential energy. When the J-10 fighter accelerates from the ground and takes off, the altitude increases, the gravitational potential energy increases, the speed becomes faster and faster, and the kinetic energy increases;

<><1) The minimum speed of the aircraft when taking off from the ground should meet mg ="k"s v <>

2) When taking off, the force diagram of the "J-10" rising at a uniform speed along a straight line at an angle of 37o to the horizontal direction is shown in the answer diagram, and the ratio of the resultant force direction of gravity and upward lifting force is 37o along the horizontal direction
