Study on Attitude-orbit Control Interference Performance of Grid Fin Layout
The main aerodynamic forces and component aerodynamic forces of a typical design point without and with jets are calculated with the computational fluid dynamics (CFD) methods,aiming at the attitude-orbit control interference problem of the nozzle and grid fin layout.The longitudinal and lateral aerodynamic forces of different combinations of circumferential positions of grid fins and jet directions are compared.The results show that under longitudinal jets,the interference of the pitching moment mainly generated by the missile body is significant whether the layout is ×-× or ×-
