为满足对平流层内多点同时进行气象探测的需求,开展了可分序释放6枚探空仪的火箭技术方案设计。通过建立火箭飞行六自由度弹道模型,在综合分析探空仪释放各种约束因素的基础上,计算获取了不同发射仰角下关键弹道点参数,表明在现有总体参数条件下以83°发射仰角规划标准弹道,可满足探空仪释放点高度、姿态及动压等要求,具备工程应用的条件。

In order to meet the need of multipoint meteorological sounding in the stratosphere,a sounding rocket design scheme of 6 dropsondes that can be sequentially released was carried out.Six-degree-of-freedom ballistic model was established for rocket flight.On the basis of analyzing dropsonde release constraint factors, the key ballistic point parameters under different launch elevation were calculated.It’s shown that the standard trajectory can be planned with the launch elevation angle of 83° under the existing general parameters, which can meet the release requirements of the height, attitude and dynamic pressure, and has the conditions for engineering application.
