摘要
Abstract
In order to maintain excellent aerodynamic characteristics of extended-range guided projectiles in the entire flight airspace while enhancing their maximum range and flight efficiency,morphing vehicle technology was applied to large-caliber extended-range guided projectiles.The aerodynamic shape and variable swept wing of a variable swept wing extended-range guided projectiles was designed.Furthermore,a trajectory optimization methodology specifically adapted for extended-range guided projectiles featuring continuous variable swept wing capability was proposed.By introducing a deformation parameter to characterize the variation of the fin swept angles of the projectile,a longitudinal dynamics model for extended-range guided projectiles with variable swept wing was constructed.Particle swarm optimization algorithm was employed,with maximum overall lift-to-drag ratio as the objective function,to simultaneously optimize wing sweep angles and rudder deflection angle.Ballistic simulation was carried out for the variable swept wing extended-range guided projectiles and its fixed shape respectively.The simulation results show that the variable swept wing extended-range guided projectiles can continuously adjust wing sweep angles according to the flight velocity of the projectile,thereby modulating aerodynamic drag and lift to maintain optimal lift-to-drag ratio characteristics throughout the ballistic glide phase.Compared to the guided projectile with fixed shape,the guided projectile with variable swept wing achieves significant range increase of 8.9%.The research method provides a theoretical foundation and reference for the optimal design of the ballistic trajectory of the continuous variable sweep wing extended-range guided projectiles.关键词
