Abstract
The invention provides a deployable radiator for a space vehicle such as a satellite. The radiator of the invention has two radiating faces, one of which is insulating over a portion of its area so that during launch and while the satellite is being moved onto station, with the radiator in the stored position, it naturally serves to keep the highest possible temperature on board the vehicle.
Claims12
A deployable radiator and a space vehicle, the deployable radiator mounted to the space vehicle, the radiator having a stored position prior to deployment and an operational deployed position after deployment;
- said radiator having two main faces comprising a first face which is stored towards the vehicle and an opposite, second face which faces towards space in the stored position;
- said first face being radiating over at least the major portion of its area;
- at least a portion of said second face being thermally insulating;
- wherein a large portion of said second face is thermally radiating, said large portion being substantially hidden prior to deployment of said radiator by other elements of said space vehicle that act as a screen during launch and during at least a portion of the transfer of said vehicle into its operational orbital position.
A deployable space vehicle radiator, comprising:
- a thin panel having a first face on one side of the panel and a second face on an opposite side o the panel;
- and
- a hinge coupled to one end of the panel, the hinge configured to extend the radiator between a first position and a second position displaced from the first position;
- and
- wherein the first face has a radiating coating over at least the major portion of its area;
- wherein at least a portion of the second face has a thermally insulating coating;
- and
- wherein a large portion of the second face has a radiating coating.
