The invention provides a one-tank multi-satellite heat balance test method. A plurality of satellites are mounted in a vacuum tank and are subjected to a heat balance test simultaneously. The one-tank multi-satellite heat balance test method comprises the following steps: pasting heating pieces for stimulating external heat flows on heat dissipation surfaces of the satellites; then spraying coatings for the heat dissipation surfaces on the heating pieces; using infrared cages for simulating the external heat flows in other regions of the satellites, wherein the plurality of satellites are mounted opposite to regions of the heat dissipation surfaces of the satellites; such a mounting layout can be adopted to reduce the mutual influence of the external heat flows of the plurality of satellites as the external heat flows of the heat dissipation surfaces of the satellites are relatively small. The method provided by the invention is simple and low in cost, and provides a new idea for solving a problem of the heat balance test method of the plurality of satellites with similar orbital conditions.
Description
Technical field [0001] The invention belongs to the technical field of spacecraft thermal control, and relates to a thermal balance test method for a tank of double stars. Background technique [0002] In recent years, with the advancement of electronic integration technology and payload miniaturization technology, small satellites have achieved rapid development by virtue of their high technical integration, low cost, and short development cycle. The development of high-performance payload and low-cost small satellites will play a role in technical traction and support for the advancement of space technology. [0003] The task now requires multiple small satellites to form a network for testing, many of which have similar orbital conditions. The thermal balance test is the main test to verify the rationality of the thermal control system design. In the current simulation methods of external heat flow in satellite ground thermal tests, there are usually the following methods: usin...
