Abstract
In order to meet the requirements of aerodynamic analysis and flight mechanics modeling for four-swing-arm spoilers in engineering applications,numerical simulation of aerodynamic adjustment of the main thrust force and lateral force is carried out respectively for the four-swing-arm spoilers,and the vector force control capability of the spoilers is obtained.Firstly,the adjustment strategy of the main thrust and lateral forces of the four-swing-arm spoilers is proposed.Secondly,a numerical simulation model for the four-swing-arm spoilers is established.Finally,the aerodynamic forces of a single spoiler,the thrust and lateral force adjustment capabilities of the four-swing-arm spoilers are studied through simulation.The simulation results indicate that the main thrust adjustment capability of the spoilers is higher than 30%.When the main thrust angle is less than 32°,the linear relationship between the main thrust force and the main thrust angle is better,and the aerodynamic interference between the spoilers is small.Furthermore,the four-swing-arm spoilers demonstrate a strong ability to adjust lateral forces,and can generate a maximum lateral force of 53.5 N.Additionally,the lateral force shows a strong linear relationship with the differential angle of the lateral force,which is very beneficial to missile attitude control.关键词
