Abstract
Abstract A release assembly using separation nuts and thrusters for ejecting a bodyith spin from a vehicle. The separation nuts are manifolded together in pairs so that failure of one squib of a pair will not affect actuation of the separation nuts, the separation nuts connecting the body to the vehicle. A pair of thrusters is manifolded together so that a single gas cartridge actuates both, the thrusters being situated to impart radial and axial components of velocity to the body upon separation to eject the body with spin from the vehicle. An electrical command energizes the squibs and gas cartridge simultaneously to actuate the separation nuts and thrusters.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
124 words
A body release assembly using separation nuts and thrusters comprising: (a) a plurality of pairs of separation nuts, each of said pairs of separation nuts having individual energy sources and being manifolded together so that in the event of a failure of the energy source for one of said separation nuts the energy source for the other of said separation nuts will actuate both separation nuts; (b) a pair of thrusters manifolded together such that a single energy source actuates both of said thrusters; and (c) means for simultaneously energizing said separation nut energy sources and said thruster single energy source; whereby a body connected to a vehicle by said separation nuts is released, having spin and a velocity component imparted by said thrusters.
Claim 2
Dependent Claim
124 words
A body release assembly using separation nuts and thrusters comprising: (a) a plurality of pairs of separation nuts, each of said pairs of separation nuts having individual energy sources and being manifolded together so that in the event of a failure of the energy source for one of said separation nuts the energy source for the other of said separation nuts will actuate both separation nuts; (b) a pair of thrusters manifolded together such that a single energy source actuates both of said thrusters; and (c) means for simultaneously energizing said separation nut energy sources and said thruster single energy source; whereby a body connected to a vehicle by said separation nuts is released, having spin and a velocity component imparted by said thrusters.
Claim 3
Independent Claim
88 words
A method for separating a body from a vehicle comprising the steps of: (a) actuating a plurality of pairs of separation nuts upon a command, and pairs of separation nuts being manifolded together to provide actuation of both separation nuts of each pair by an energy source, to separate said body from said vehicle; and (b) thrusting said body with a pair of thrusters simultaneous with said command, said thrusters being manifolded together to use one energy source, to impart spin and a velocity increment to said body.
Claim 4
Independent Claim
88 words
A method for separating a body from a vehicle comprising the steps of: (a) actuating a plurality of pairs of separation nuts upon a command, and pairs of separation nuts being manifolded together to provide actuation of both separation nuts of each pair by an energy source, to separate said body from said vehicle; and (b) thrusting said body with a pair of thrusters simultaneous with said command, said thrusters being manifolded together to use one energy source, to impart spin and a velocity increment to said body.
