摘要
设计了一种地面高速定向抛投系统。该系统将抛投试验品安装在火箭橇头部,利用悬索装置约束火箭橇定向飞行,加速试验品至亚音速状态,在悬索末端利用分离装置拦截火箭橇,试验品在惯性作用下继续飞行,实现试验品与火箭橇分离并定向抛射。介绍了高速抛投系统的组成及工作原理,推导了火箭橇质量、加速距离等参数的计算公式,仿真计算了悬索下拉幅度。利用新设计的悬索火箭橇高速抛投系统成功完成了某型产品地面高速抛投试验,试验结果与仿真计算结果一致。
This paper designs a new kind of high speed directed throw device. Testing product is installed in the front part of the rocket, The system use two paralleled ropes to restrain the rocket, accelerate the testing product to subsonic speed, using a separate device which install in the end of the rope, system can separate the rocket and the testing product, and the testing product can fly freely according to inertia effect. This paper introduce the high speed throw system’s structure and operating principle, and give calculation formula of rocket’s mass, and calculate the accelerate distance of the rocket, finally we uses dynamical simulation to calculate the dragging effect of the rocket and give the results. Recently Using this high speed directed throw system, we successfully accomplished high speed directed throw tests of some kind of new drag parachute, the test results are just same as calculation results.
