摘要
雷达天线和柱形气囊共形耦合可使雷达具备大视距和全向探测能力,同时实现飞艇平台的轻量化。在分析阵面载荷、囊体内压和囊体刚度三者关系的基础上提出了一种雷达天线与柱形气囊的共形方案,解决了雷达天线和气囊共形的三个关键问题,即气囊褶皱问题、气囊成形问题和连接器的设计问题。仿真分析表明,选择合理充气内压同时对气囊蒙皮施加一定的轴向预张紧力可有效控制气囊径向形变、轴向弯挠以及蒙皮屈曲,该雷达天线与柱形囊体共形设计方案能够满足工程应用要求。
It is realized that radars will have long range and all-round detection capability and the airship platform will be lightened by the way of conforming antennas to inflatable cylinder. An idea o~ conforming antennas to cylinder is presented on the basis of an analysis of the relationships among load, pressure and stiffness. Three key problems of wrinkles, shape and linker design are resolved. The simulation results show that the combination of suitable pellicle pressure and axial tensile stress can control the radial distortion, axial deflection, and pellicle buckling effectively. The design is able to realize the engineering purpose.
