Abstract:

APL spacecraft require equipment 1 to initiate despin and solar blade unfolding 2 to separate the spacecraft from the launch vehicle injection stage 3 to yaw the injection rocket after separation to prevent collision with the spacecraft. This report describes a unique simplified separation system which accomplishes the same objectives, but has the following advantages over the method presently used 1 functional components are 60 lighter 2 it has no batteries or wiring 3 it requires no ordnance of any kind 4 it is immune to RF, static, or other electrical background disturbances 5 its environmental temperature limitations are far in excess of similar limitations on the spacecraft and the launch vehicle 6 it has indefinite shelf life without servicing 7 its operation is completely independent of the launch vehicle configuration and 8 it can be tested and operated at any place any desirable number of times without hazard to itself or adjacent personnel or equipment.
