摘要
大功率高热流密度固态发射机是环境一号C卫星有效载荷中的关键设备,对整星的热设计影响很大。固态发射机热设计的目的,是满足固态发射机的温度需要,从而确保固态发射机的安全可靠工作。该文论述了环境一号C卫星固态发射机热控设计及解决的关键问题。飞行遥测结果表明,固态发射机热控设计正确、方案合理,很好地满足了固态发射机的温度要求。
Solid-state transmitter with large power and high heat flux is a key equipment of an HJ-1-C satellite; therefore, it has a great influence on satellite thermal design. Thermal design ensures that the solid-state transmitter works well within the allowable temperature limits of the equipment. The solid-state transmitter thermal design and solved key problems are provided in accordance with the HJ-1-C characteristics. Moreover, an analysis of satellites on orbit was performed. Based on the telemetry data, the thermal control design is shown to satisfy the temperature requirements of the solid-state transmitter.
