摘　　要：小型化指令发射机安装于发动机上方的飞机垂尾根部,振动剧烈,安装空间非常有限,飞机能提供的冷却风很少,难以满足发射机的散热需要。文中通过模块化方法对发射机进行了整体结构设计,利用数值仿真对发射机进行了抗振和强度设计,并针对发射机的特点对其进行了热设计和高压绝缘设计。实验结果表明,该发射机具有良好的工作稳定性和可靠性。Small airborne command transmitter is installed above the engine, at the root of the vertical tail. Installation space is very limited and vibration is severe. Cooling air that aircraft can provide is very few. It is difficult to meet the cooling requirements of the transmitter. In this paper, overall structural design is per- formed by modular method. Vibration and strength design and high voltage insulation design are carried are analyzed by means of numerical simulation. Thermal out according to the characteristics of the transmitter. Test results show that the transmitter has good working stability and reliability
