SPACE VEHICLE INSTRUMENTS TESTING SYSTEM Russian patent published in 2009 - IPC B64G7/00 B64G1/50 

FIELD: aircraft industry.

SUBSTANCE: invention refers to tests of space vehicle elements, and namely instruments during thermocycling thereof. According to invention, system comprises a thermal behaviour device. Liquid path of that device is connected through outlet and inlet hydraulic connectors to inlet and outlet hydraulic connectors of liquid path of thermocycling circuit of tested instrument. The latter is installed in thermal vacuum chamber. Outlet and inlet hydraulic connectors of the above device are connected to inlet and outlet hydraulic connectors of the above thermocycling circuit through the attachment point. That point is made in the form of two hydraulically disconnected liquid path lines. The first line includes inlet hydraulic connector attached to outlet hydraulic connector of the thermal behaviour device. That inlet hydraulic connector is connected in-series through a valve and heater to outlet hydraulic connector of that line, which is attached to inlet hydraulic connector of thermocycling circuit. The second line includes inlet hydraulic connector attached to outlet hydraulic connector of thermocycling circuit, a valve and outlet connector, which are connected in-series. Outlet connector is attached to inlet hydraulic connector of the thermal behaviour device. Bypass liquid paths each of which includes one of two cavities of recuperative heat exchanger are connected hydraulically and parallel to valves of both lines.

EFFECT: enlarging functional characteristics of thermal behaviour devices (without modification thereof) used in space vehicle instruments testing system.
