Hello dear, the above is the answer I have compiled for you, if my answer is helpful to you, I hope Qiaochun can evaluate my service, your praise is the motivation of my former filial piety, thank you for your support I wish you a happy life Oh guess talk.

After the 70s, the design thinking of fighter planes around the world has changed, no longer pursuing "higher and faster", but focusing on improving the aircraft's medium and low-altitude maneuverability, and telling the good on-board electronic equipment, ** and fire control system. In order to adapt to this trend and meet the new needs of the troops' equipment, Shenfei Company developed the J-8 aircraft on the basis of the J-8. On June 12, 1984, the prototype made its first successful flight.

On March 18, 88, the design of the J-8 was finalized. On October 15 of the same year, the Military Products Finalization Committee officially approved the design of the J-8 aircraft.

The development of the J-8 focuses on the ** system, fire control system, on-board electronics and power plant. In order to provide space for the large-caliber radar antenna, the air intake method on both sides is adopted, which is also the biggest difference between the aircraft and the J-8.

The J-8 was replaced with two turbojet-13A twin-rotor engines, each with a thrust of 6,600 kg. The increase of engine thrust can improve the maneuverability of the aircraft at medium and low altitudes, and also improve the take-off and landing performance. The external plug-in has been increased to seven, which can hang a variety of ** or auxiliary fuel tanks, so that the aircraft has all-weather interception capabilities and ground attack capabilities, and is equipped with radar-guided medium-range interceptor missiles. The nose landing gear is rear-mounted with a 23mm double-barreled gun.

Collapsible pelvic fins are installed in the lower part of the tail.

There is also a big breakthrough in the body material of the J-8, which is the first time that China has used composite materials on a large area on a self-designed fighter.

In addition, on the basis of the J-8, Shenfei has successively developed improved models such as J-8IIM, J-8III, J-8D, J-8F, and J-8T, which has made a significant leap in the technical level of the J-8 prototype, and the main improvements include fire control system, power plant and supporting airborne equipment. The development plan of the J-8 aircraft highlights the performance of high altitude, high speed, increased range, improved climb rate, and enhanced firepower. In view of the shortcomings of the J-7 aircraft, it has been improved item by item, and all performance indicators have been improved

a) the maximum speed is Mach number; (2) The maximum ceiling is more than 20,000 meters; (iii) the maximum rate of climb is 200 meters per second; (4) The basic range is 1,500 km, and the maximum range is 2,000 km; (5) Stipulating the time for combat in the air at an altitude of 10,000 meters; (6) Installation of improved design of aircraft guns and air-to-air missiles; (7) Installing radars with a large search range. The J-8 aircraft adopts the aerodynamic layout form of nose air intake, large sweep angle, small aspect ratio, thin delta wing, flat tail socks and double ventral fins. Using two turbojet 7A engines, the thrust-to-weight ratio of the aircraft is , which is better than that of the J-7 aircraft.

On 6 July 2014, the UK revealed a number of new design concepts for future combat aircraft, claiming that the technology could be adopted in less than 30 years.

The first related concept is the on-board 3D printer. Using high-hardness and low-density alloy materials, some small UAVs are printed in action to perform combat missions. The second design concept is a "morphed" fighter, which consists of multiple small fighters combined into a large fighter to extend the range and save fuel.

After arriving at the destination, the fighters can "split" to carry out their own tasks to increase the combat coverage, and then fly back to the base combustion site after completing the mission. The third design concept is a "self-healing" fighter (pictured below). After the fighter is hit by the enemy**, it uses carbon nanotubes distributed in the fuselage and wings to deliver the adhesive liquid and automatically repair the "wound".

For the first time, the Air Force J-20 fighter 7 aircraft are shown in the same frame, in addition, there are many new achievements of China's strong country and rejuvenation of the army, and the new achievements of the Air Force will be introduced below. In addition to the J-20, the Y-20 will also be displayed in flight, and the J-10B, H-6K and Air Police 500 will be statically displayedIt comprehensively demonstrated the new achievements made by the Air Force in reform, opening up, and reforming and strengthening the army.

In the new achievements of a strong country,".The "national brand" new fighter plane and the Red 9 surface-to-air missile have been installed in the air force units one after another, and they have been put into training and preparing for war in the new eraThe actual combat training of the Air Force is expanding to the plateau, the sea, and the ocean, and China's Air Force is getting stronger and stronger.

At present, the world is in a period of great development, transformation and adjustment, instability and uncertainty are prominent, and China's geostrategic environment, especially the maritime security environment, is becoming more complex, which has an increasingly deepening impact on the overall situation of China's security strategy。On the new journey of strengthening the country and rejuvenating the army, the officers and men of the Air Force patrolled the East China Sea, the West Pacific, the South China Sea, and the islandsThis is a new challenge entrusted by the times and a new mission entrusted by the party and the people. The unprecedented broad territory provides traction for outstanding talents to stand out and creates a stage; The new mission has set higher demands on the new generation of commanders and fighters, and has also provided an opportunity to serve the motherland and make meritorious contributions.

As the "leading goose" of an ace force in the Air Force,It has completed the protection of air rights in the Diaoyu Islands, the normalization of the control of the air defense identification zone in the East China Sea, and the advance out of the western Pacificand flying over the first island chain, and making important contributions to safeguarding national sovereignty, security and development interests.

Aerospace technology has overcome a difficult hurdle and is developing step by step, striving to catch up with and surpass other countries.

The fact that our country can trample on the military technical problems one by one is the achievement of our strong country!

The arrival of 5G is also part of strengthening the country and rejuvenating the army, not only in life, but also in the military, and there will be great achievements.

In addition to displaying 20 fighters in the Air Force and seven aircraft in the same frame. There are many other new achievements in our country, all of which have demonstrated our country's strong overall strength.

In addition to the Air Force J-20 fighters. There are also new achievements in China's aerospace industry. All of them demonstrate the continuous enhancement of China's comprehensive national strength.

For the first time, the Air Force J-20 fighters and 7 aircraft were shown in the same frame, and the Dalian maritime aircraft carrier exercise was a new achievement in strengthening the country and rejuvenating the army!
