Speech Title:
On the Research Progress of Thrust Vector Technology
 
Abstract:
With the development of the aeronautic science and technology,Thrust vectoring technology, which can meet the performance requirements of future aircraft, such as unconventional mobility and agility, short-range/vertical takeoff and landing, supersonic cruise, etc., is one of the essential key technologies for future aircraft. Thrust vectoring nozzle is the core part of the thrust vectoring technology, and its performance determines the level of the engine technology. 
In this presentation, the importance and urgent requirement of thrust vector is introduced firstly; then the mechanical variable thrust vectoring nozzle and fixed-geometry fluidic thrust vectoring nozzle are compared; and then the main research developments about the typical types of the fluidic thrust vectoring nozzles are sumarized; Finally, the Bypass Dual Throat Nozzle (BDTN) developed by our group are focused and the main research progress are introduced in details.
