the F-35 has a single rounded parabola like fuselage on top, whereas the J-20 and F-22 reveal a flat upper fuselage blended into two separate rounded engine pathways. This kind of engineering might also be an effort to maximize maneuvering, vectoring and...
An unmanned aerial vehicle (UAV) with omnidirectional thrust vectoring includes a central unit, a connective structure, and a plurality of propulsion units with omnidirectional thrust vectoring allowing a full six degrees of freedom. A vectored propulsion unit comprises thruster vectored by an ...
1) thrust vectoring efficiency 矢量偏转效率1. The influences on the thrust vectoring efficiency and the thrust ratio of different injection parameters and the nozzle pressure ratio were analyzed and investigated. 比较了在不同喷射参数和不同喷管落压比NPR(Noz-zle Pressure Ratio)下的流场特征,分析了这些...
