What are the advantages of China J-10 fighter layout?

According to the data and imagination, J-10 is a 10-ton medium and light air superiority multi-role fighter with single engine and single vertical tail. The belly air intake and the tightly coupled canard aerodynamic layout with double delta wings and delta front wings popular in the world are adopted. Its advantages are that it can not only give full play to the advantages of delta wing aircraft at high altitude and high speed, but also increase the lift through the front wing, ensure the maneuverability of low-altitude subsonic combat and greatly shorten the take-off and landing distance. These conjectures reflect that the combat mission of J-10 is different from that of the lion: the lion adopts the lower wing and fixed inlet, and the battlefield interception is the main task, supplemented by air superiority;

J-10 is a two-dimensional adjustable inlet and a single-wing central shock cone, which emphasizes the combat performance in low-altitude air combat, the maneuverability at high altitude and high speed, and the ground attack performance. Moreover, J-10 has better stealth performance and internal fuel tank capacity, because the air inlet moves forward, the air inlet is slightly S-shaped, and the wing-body fusion body is fuller. The J-10 nose landing gear has two wheels, and the demand for rough landing is considered. The main landing gear is under the fuselage, which gives up valuable space under the wing and is convenient for carrying more external weapons. There are 1 1 external points.

The maximum external auxiliary fuel tank of J-10 is 4100L. These data show that J-10 has enough thrust to meet the needs of various maneuvers, which greatly improves the performance of horizontal acceleration, climbing and hovering. You can even climb vertically effortlessly in air combat.

The J-10 adopts the aerodynamic layout similar to that of the Lion Fighter designed in the early 1980s on the basis of the duck layout of the J -9, but it is modified to meet the requirements of the China Air Force, and adopts the large size and heavy weight of China's new fighter.

The J-10 adopts delta wing and canard wing layout. At the same time, J-10 retains the movable wing technology adopted by Lion: the leading edge of the outer wing is a movable flap, and the fixed inner wing produces excellent aerodynamic performance with the cooperation of the wings of the fully moving canard J-J 10 cockpit simulation system. The horizontal tail position of a conventional aircraft is occupied by four movable ailerons at the trailing edge of the delta wing. There is no pylon of light air-to-air missile at the wing tip, which is different from "Lion" and "Gryphon".

The most commendable feature of J-10 layout is the integration of wing and body. By carefully designing the curved surface of the joint between the main wing and the middle of the fuselage, the internal volume of the aircraft is increased and the aerodynamic lift effect brought by it is effectively utilized. There are no other structures on both sides of the fuselage at the rear of the main wing, which once again embodies the design concept of wing-body integration, except that two external oblique ventral fins are added below the abdomen at the front end of the tail nozzle. These two ventral fins are used to maintain the stability of the aircraft when flying at high angle of attack, and they have high vertical tails. Like the lion, J-10 also designed four speed brake, two of which are located behind the main wing at the upper part of the fuselage, and the other two are only located between the ventral fins at the lower part of the tail.

Besides the wing, another main difference between J-10 and Lion is the air inlet. The intake of the lion is similar to F- 16, and the geometry is fixed. J-10 adopts two-dimensional adjustable inlet and central shock cone, which is somewhat similar to F-4 Ghost II. Only J-10 translates the "ghost" inlet below the belly of the aircraft, and the front part of the inlet is formed by the adjusting plate, which provides the airflow required by different flight states for the engine and is more suitable for high-performance air-to-air operations.

In addition, the high-efficiency rectification and compression capacity of the adjustable inlet greatly improves the engine thrust when the aircraft flies at supersonic speed, so that the aircraft can obtain better climbing and high-speed performance. The disadvantages of this inlet layout mainly include poor stealth effect, heavy weight, complex structure and increased production cost. At the same time, the power and adjusting system of the adjusting plate also increase the maintenance burden of the aircraft.

Aerodynamic layout suitable for supersonic flight, powerful engine and adjustable inlet make the maximum speed of J-10 reach 2600 km/h, which is greater than 2340 km/h claimed by Lion. The superb performance of J-10 focuses on air-to-air combat, so it will be a weapon for air defense and interception tasks.
