摘　　要：根据水平空中发射固体有翼运载火箭的飞行特点,提出了一种飞行程序角的工程设计方法,并给出了三级飞行段及滑行段飞行程序角的表达式,建立了发射轨道优化模型,应用基于方向的遗传算法对其发射轨道进行了优化。该方法适用于水平空中发射固体火箭方案论证和初步设计。On the basis of flying characters of horizontally air-launched vehicle with wings,a method of fligh trajectory calculation and optimization was put forward,and expressions of program angle in burning phase and glide phase were presented. Optimization results were given with genetic algorithm based on direction.This method is useful in feasibility study and preliminary design for horizontal air-launched vehicle.
