ABSTRACT:
An arrangement for mounting a panel on a spacecraft employs a spring sheet which serves to mount one end of the panel to the spacecraft for pivoting the panel with respect to spacecraft and which is capable of storing spring energy for actuating the panel to pivot it from one of a stowed position and a deployed position to the other. In the preferred embodiment, the panel is a radiator for rejecting waste heat into outer space from a dynamic isotope power system of the spacecraft.
