China J-14 fighter plane uses self-developed vector engine

Vector jet engine is the nozzle can rotate in different directions to produce the acceleration in different directions.

Do not use technology, thrust vectoring aircraft, jet engines and aircraft axis are overlapping, resulting in forward thrust is also along the axis, in which case the engine thrust is used to overcome resistance by the aircraft to provide aircraft to speed up the driving force.

The use of thrust vector aircraft technology, it is through the nozzle deflection, resulting from the use of engine thrust, torque control was unnecessary to achieve attitude control of aircraft. Its outstanding feature is the control of torque and is closely related to, but not the aircraft itself, the impact of gesture.

Therefore, we can ensure that low-speed aircraft, mobile high angle of attack flight control surface to manipulate the use of near-failure to provide the additional thrust vector control of motor torque to control the aircraft.

Requirements of the fourth generation fighter aircraft to have the ability to post-stall maneuver, that is, high angle of attack of mobility. The use of thrust vector aircraft technology not only greatly enhance its mobility, but also have unprecedented STOL capabilities, this is because the use of thrust vectoring technology toroidal volume of aircraft lift and thrust in the direction of the lift are beneficial to reduce the weight of the aircraft from the ground speed and to shorten the distance between the aircraft’s roll.

In addition, as a result of thrust-vectoring nozzle is easy to achieve reverse thrust, the aircraft after landing is also a substantial increase in braking force, so to shorten the landing roll, the more distance. If the engine nozzle deflection not only from top to bottom, but also about deflection, then the thrust is not only able to provide aircraft pitching moment, but also to provide yaw torque, which is the whole vector aircraft.

The use of thrust vectoring technology to improve the efficiency of the control of the aircraft so that aircraft’s aerodynamic control surfaces, such as the vertical tail and the legislation can be greatly reduced, and thus can reduce the weight of the aircraft. In addition, the vertical tail and the formation of legislation corner reflectors has also reduced, stealth aircraft have also been improved performance.

Binary and ternary vector vector engine means the engine nozzle in the engine installed on the end of the diversion system for the high temperature and high pressure gas to change the direction of smoke, and then change the whole thrust of the state, to complete a series of mobility.

Vector sub-jet system of two binary and ternary. Nozzle end of the dual system can only be used to swing up and down, high temperature and high pressure gas can change the direction from top to bottom; ternary system, the end of the engine nozzle can be used for full-swing, high temperature and high pressure gas also can change the direction of omni-directional.

Army has published a slump in China Thrust-Weight Ratio turbofan engine successfully developed the core machine!

Axisymmetric Vectoring TVC successfully developed touch control! Aircraft thrust vectoring technology is by changing the direction of aircraft engine exhaust to provide more torque steering technology. Aircraft thrust vectoring technology enables the ultra-fighter maneuverability, short take-offs and landings and low detectability, greatly improve the fighter’s combat effectiveness and survivability.

The United States, Russia and other developed countries have to give priority to the development as an important technology. Thrust vector technology in the aircraft study, the direction of change in engine exhaust, that is, the research thrust vectoring nozzle is the key yet decisive element, you must first research and development. Axisymmetric Vectoring Exhaust Nozzle (AVEN) is closed in the conventional mechanical nozzle extended out to develop a thrust-vectoring nozzle, by deflection diffuser nozzle to change the direction of the engine exhaust. The whole thrust vector technology in terms of aircraft, AVEN has a simple, lightweight, low-risk characteristics of the aircraft, engine modification requirements of the host small, is to implement the best technology, thrust vectoring nozzle program. AVEN technical objective of the study was completed by the target platform AVEN vortex test pieces of fan development, and to achieve thermal test.

However, the vector engine in China, there has been a new breakthrough, but in view of the confidentiality of the time being can not be made public.

But the United States and Russia will not be able to present the best of vector engine sold to China, so China’s latest fighter planes will be used self-developed engine, the J14 in the load test on the vector engine is not abroad, which shows that the vector engine may have made a major breakthrough, because we used the engine of the latest fighter planes can not be lower than the level of J10.

From the current test of the J14 are gradually exposed some of the news can see that China’s 4th generation fighter aircraft and 5 have basically been entered on behalf of all the stages of self-development, and in many ways leading the world to start and we look forward to continuing to explore all of the J14 an early debut for China’s military power spectrum of the new chapter again.
