The invention discloses a spacecraft deck and a spacecraft. The spacecraft deck comprises a structural deck. The storage box is integrated in the structural cabin plate and is used for storing a liquid working medium; the air capacitor is integrated in the structural cabin plate and is used for storing a gaseous working medium; the thermal control unit is arranged on the structural cabin plate and comprises a condensation end and a gasification end, the condensation end is connected with the storage box through a pipeline, and the gasification end is connected with the gas capacitor through a pipeline; the thruster is arranged on the structural cabin plate, and the air capacitor is connected with the thruster through a pipeline. The spacecraft cabin board can utilize the waste heat recovery function of the thermal control unit to carry out phase change conversion on a propelling working medium, ammonia gas obtained after liquid ammonia in the thermal control unit absorbs heat and is gasified is supplied to the thruster, part of heating power for heating the liquid ammonia by a propelling system to gasify the liquid ammonia can be saved for the whole satellite, and space on the satellite and the weight of the whole satellite are saved; a thermal control system and a propulsion system can be combined, the system design is comprehensively optimized, a novel satellite structure is achieved, and thermal control and propulsion integrated design is achieved.
本发明公开一种航天器舱板及航天器,航天器舱板包括结构舱板;集成于结构舱板内部的贮箱,用于贮存液态工质;集成于结构舱板内部的气容,用于贮存气态工质;热控单元,设置于结构舱板,热控单元包括冷凝端和气化端,冷凝端与贮箱通过管路连接,气化端与气容通过管路连接;推力器,设置于结构舱板,气容与推力器通过管路连接。航天器舱板可利用热控单元对余热的回收功能对推进工质进行相变转化将热控单元中液氨吸热气化后的氨气供给推力器,可以为整星节约推进系统加热液氨使液氨气化的部分加热功率,节约星上空间和整星重量,并且可以将热控系统与推进系统合并,全面优化系统设计,实现一种新型卫星结构、热控和推进一体化设计。
