Abstract: A combination connector (20) includes a first half connector (22) with a fixed central body (40) and a slidable exterior housing (54) that is biased to a first position, and a second half connector (24) with a fixed exterior housing (70) and a slidable interior body (82) that is biased to a first position. The fixed central body (40) of the first half connector (22) has electrical contacts (42) on its periphery, and the fixed exterior housing (70) has electrical contacts on its interior wall. The slidable exterior housing (54) of the first half connector (22) protects the connection points before the connection is made, and is pushed back to expose the connection points as the two connectors are mated together.

Abstract: A missile launching system with an open-ended cylindrical container (10) having a bore in which a slidable piston (20) is located between the missile (12) and a gas generator (14) adjacent the container aft end (16). The piston (20) area is substantially the same as the container bore at the aft end (16). An internal ring (42) forms a reduced area throat for gas exiting via the aft end of the container (10) with the ratio of the piston area to the throat area, A.sub.p /A.sub.t, being functionally related to the propellant physical characteristics.
