Abstract:This paper performs numerical simulations on the main thrust and lateral force adjustments of four swing arm spoilers, thereby determining their vector force control capabilities, which meet the need of aerodynamic analysis and flight mechanics modeling in engineering. The paper begins by presenting strategies for adjusting the main thrust and lateral forces of the four swing arm spoilers. Secondly, a numerical simulation model for four swing arm spoilers is established. Finally, the paper examines the aerodynamic forces of a single spoiler, along with the thrust and lateral force adjustment capabilities of the four swing arm spoilers system through simulation. The simulation results indicate that the main thrust adjustment capability of the spoilers surpasses 30%. When the main thrust angle is below 32°, there is a strong linear relationship between the main thrust and the main thrust angle, with minimal aerodynamic interference between the spoilers. Furthermore, the four swing arm spoilers demonstrate a strong ability to adjust lateral forces, capable of generating a maximum lateral force of 53.5N. Additionally, the lateral force shows a strong linear relationship with the differential angle of the lateral force, which greatly aids in missile attitude control.
