摘要
针对炮射侦察弹的工作特性,提出了弹道设计方案.建立了炮射段、分离段、减速段弹道模型,推导了开伞时间与分离时间、降落伞面积与弹道末端约束的关系.以弹道射程最大为目标,以发射角、分离时间点作为设计变量进行了弹道优化设计,确立了发射角44.0°与分离时间点32.33s为最优结果,完成了弹道仿真计算.结果表明:论文设计的炮射侦察弹弹道方案合理,可用于指导炮射侦察弹弹道方案设计.
Trajectory project was proposed for gun-launch surveillance projectile （GI.SP） considering the requirements for rapidness. The mathematical models of gun-launch phase, separate phase and deceleration phase were established. The relationship between parachute opening time and separation time as well as the relationship between parachute area and final con- straint were derived. In order to achieve maximum range, the optimal models of gun launch and deceleration trajectory were established, and then these two phase trajectories were designed. Launch angle 44.0°and point 32.33 s of separation time were found to be the optimal results,and the ballistic simulation was completed. The results show that the trajectory project for GLSP is reasonable,and the proposed approach can be used to direct the design of trajectory of GLSP.
