Portable nano-satellite atmospheric-pressure thermal test measurement and control system

Abstract

The invention discloses a portable nano-satellite atmospheric-pressure thermal test measurement and control system. The system includes an auxiliary external flux simulation system, a temperature measuring system, and a pollution measuring system which are used in spacecraft vacuum thermal tests. The auxiliary external flux simulation system generates a predetermined flux density through a temperature controlling instrument and a power supply passing a test piece local heater. The temperature measuring system obtains test piece surface temperature by means of a platinum resistor. The pollution measuring system includes a balance frequency and a glass test piece contaminant capacity measuring system. According to the invention, the system can simulate external flux imposed on the nano-satellite in orbit under atmospheric pressure, measures corresponding thermal property and contaminant capacity, and conducts atmospheric-pressure thermal tests of the nano-satellite in a rapid and convenient manner. The system has a high reliability and flexibility, can effectively reduce test expenditure and test period, and increases production efficiency.
