摘要
Abstract
The thrust vectoring control technology is the main technology for the 4th generation fighter. The computational study of interaction flows between vectoring jet and high speed main flow around a simplified fighter configuration is presented. The infections of the parameters such as Mach number of main flow, attack angle, nozzle deflection angle, Mach number, total pressure and total temperature of jet flow are system researched. The physical mechanism of the main flow/vectoring jet flow interaction is also analyzed. Numerical simulation results show that for the simplified fighter configuration, the thrust vectoring jet effect on the high speed main flow is only effects on the aircraft components near the nozzle exit and have little effect on the aerodynamic characteristics of aircraft except at high angles of attack. However, the high speed main flow has strong interaction with thrust vectoring jet flow. With the increasing of the angle of attack and Mach number the decrease of thrust vectoring angle are increasing.关键词
