Several DPR hardware models have been manufactured according to the resulting design.
DPR EM manufactured and successfully tested. LHP showed a stable performance during all tests being able to transport the requested 1000w along the operating temperature range.
DPR QM manufactured, integrated (thermal configuration) and successfully tested. Thermal performance tests were conducted in-orbit environment, where main performance parameter – heat rejection capability – has been verified in worst conditions (hot environment, maximum power and failure configuration)
Deployment mechanism EM as planned, and QM successfully manufactured and tested.
New material Cr(VI) free development achieved
Surtec 650 was successfully tested accoding to the evaluation and qualification protocols.
MAP EPOX11 was successfully tested accoding to the evaluation and qualification protocols
LEO Radiator panel for LEO applications designed, developed and successfully tested. Analysis and test results confirmed that LEO DPR Is able to reject 220 W with working fluid at 25ºC and external sink temperature at -60ºC. The thermal performance and mass density are competitive with those of similar products.
Main dissemination activities related to this project are as follows:
- Deployable radiator technology presentation at the following conferences and congress CCPIF, KTD and ICES.
- Replacement alodine 1200S congress at ASST 2018 and STM-32.
DPR exploitation has a high potential due to market competitiveness to increase mission capability to cope with very power demanding satellites. DPR mandatory to cover certain power demanding missions. Also allows to come with future power demand increases and permits the use of existing platforms for high performance missions without the need to entirely redesign the satellite’s architecture.
