Abstract

Radiator assembly (10) for use on a spacecraft (12) is provided including at least one radiator panel assembly (26) repeatably movable between a panel stowed position (28) and a panel deployed position (36), at least two flexible lines (40) in fluid communication with the at least one radiator panel assembly (26) and repeatably movable between a stowage loop (42) and a flattened deployed loop (44).

Independent Claims | See all claims (28)

  1. 1. A radiator assembly for use on a spacecraft comprising: at least on radiator panel assembly repeatably movable between a panel stowed position and a panel deployed position; at least two flexible lines in fluid communication with said at least one radiator panel assembly, said at least two flexible lines repeatably movable between a stowage loop configuration and a flattened deployed loop configuration.
  2. 16. A radiator assembly for use on a spacecraft having at least one cargo door comprising: at least on radiator panel assembly repeatably movable between a panel stowed position and a panel deployed position, said at least one radiator panel assembly positioned adjacent the cargo door on the spacecraft while said at least one radiator panel assembly is in said panel stowed position.
  3. 24. A radiator assembly for use on a spacecraft comprising: at least on radiator panel assembly repeatably movable between a panel stowed position and a panel deployed position; at least two flexible lines in fluid communication with said at least one radiator panel assembly, said at least two flexible lines repeatably movable between a stowage loop configuration and a flattened deployed loop configuration; and a stowage box housing said at least two flexible lines when said at least two flexible lines are in said stowage loop configuration, wherein said stowage box protects said at least two flexible lines from high bending load associated with launch and landing.
  4. 25. A radiator assembly for use on a spacecraft comprising: at least on radiator panel assembly repeatably movable between a panel stowed position and a panel deployed position; at least two flexible lines in fluid communication with said at least one radiator panel assembly, said at least two flexible lines repeatably movable between a stowage loop configuration and a flattened deployed loop configuration; and at least one spreader block attached to said at least two flexible lines, said at least one spreader block forming an insulation gap reducing thermal communication between said at least two flexible lines.
