摘　　要：弹出式减速翼机构用以在某水下无人航行器末端弹出4个减速翼,增大阻力使航行器速度快速减速,与拦截网配合进行拦截回收。为降低不同减速翼的展开及到位时间的不同步性对姿态控制产生的影响,本文构建了一种力学模型,并基于Matlab设计编写了相应仿真程序,对弹出式减速翼机构的展开时间等参数进行了仿真计算,得到了不同装药量的推销器在同一水环境下对减速翼展开时间的影响,确定了最优的设计参数。The underwater pop-up decelerating wing system is used for popping up four decelerating wings in the end of the unmanned underwater vehicle,which could increase the resistance so as to slow down the vehicle rapidly and intercept the vehicle for recycling.In order to reduce the impacts on holding patterns generated by deploying and in-place time asynchronism of different wings,a mechanical model is builded,and matlab programme is designed for simulating and calculating deploying time,which could acquire dynamic performance of different loading doses of pyrotechnics under the same water environment and determine optimal design parameters.
