High-powered satellites are required to obtain more heat rejection area. Deployable radiator, which is stowed during launch and deployed in orbit to obtain the additional heat rejection area, is key bus technology. This paper presents a design and engineering model test of developed deployable radiator on ETS-VIII (Engineering Test Satellite VIII) using RELHP (Reservoir Embedded Loop Heat Pipe). RELHP has an evaporator, condenser and transport lines to circulate a fluid, and that utilizes the evaporation and condensation of the working fluid to transfer heat. Developed RELHP has following characteristics. (1) It has 1.0 micron pore diameter fine-poured wick to achieve more higher heat transport capability. (2) It can start-up at any time by supplying the wick with working fluid, because liquid reservoir is located in the evaporator itself. Results of the thermal balance test and analysis will be described and discussed.
