Abstract
A deployable radiator arrangement for cooling a geostationary earth orbit spacecraft is provided. In some aspects, the geostationary earth orbit spacecraft may comprise first and second deployable radiators mounted on an east or west surface of the spacecraft when stowed. The first and second deployable radiators are configured to rotate into a north and south facing position, respectively, when deployed. The geostationary earth orbit spacecraft may further comprise first and second fixed radiators disposed on a north and south surface of the spacecraft, respectively. The first and second deployable radiators are thermally coupled to the first and second fixed radiators, respectively.
Claims24
A geostationary earth orbit spacecraft comprising:
- first and second deployable radiators mounted on an east or west surface of the spacecraft when stowed,
- wherein the first and second deployable radiators are configured to rotate into a north and south facing position, respectively, when deployed, and
- first and second fixed radiators disposed on a north and south surface of the spacecraft, respectively,
- wherein the first and second deployable radiators are thermally coupled to the first and second fixed radiators, respectively.
A method for cooling a geostationary earth orbit spacecraft, the method comprising:
- mounting first and second deployable radiators on an east or west surface of the spacecraft;
- mounting first and second fixed radiators on a north and south surface of the spacecraft, respectively;
- thermally coupling the first and second deployable radiators to the first and second fixed radiators, respectively;
- and
- deploying the first and second deployable radiators by rotating the first and second deployable radiators into a north and south facing position, respectively.
