IberEspacio has complete the 0G deployment test of the Deployable Thermal Radiator (DTR) for Electra telecommunications platform, a full-electric platform developed by German satellite manufacturer OHB.
This test is one of the major milestones of the development and qualification of this radiator, under complete responsibility of IberEspacio. The model that has been tested is the Flight Model and the test was performed at IberEspacio facilities in Torrejón de Ardoz, Madrid, Spain.
The DTR is a 2,5 square meters structure that radiates heat by both sides, allowing to Electra platform to increase the heat reject capability without increasing the total size of the spacecraft. The DTR completed with two Loop Heat Pipes that collect the heat from the satellite and transport it to the radiator. Condenser lines are embedded inside the radiator. The DTR also has specific deployment mechanism and a new low profile developed and qualified Hold Down and Release Mechanism.
