A substantially one piece molded shell ejection seat (10) having a rocket motor propulsion system (74), the propulsion system (74) being adapted to be integrated into the molded seat (10) during the molding process. The seat body (12) has upper and lower side walls (14, 16, 20, 22), front wall (60)

A substantially one piece molded shell ejection seat (10) having a rocket motor propulsion system (74), the propulsion system (74) being adapted to be integrated into the molded seat (10) during the molding process. The seat body (12) has upper and lower side walls (14, 16, 20, 22), front wall (60) between the lower side walls (20, 22) and back wall portions (30, 32, 34, 36, 38, 40, 42, 44). A molded backrest panel (50) is removably secured to the body (12) to extend generally between the upper side walls (14, 16). The rocket motor propulsion system (74) is incorporated within the body (12) below the upper side walls (14, 16), within the lower side walls (20, 22), generally rearwardly of and below the backrest panel (50), and generally rearwardly of the occupant sitting area (66). A rocket nozzle (78) is connected to the motor (86) by a manifold (82) and is fitted generally within the lower back seat periphery and seat envelope. The rocket motor propulsion system (74) is formed as a consolidated honeycomb-type assembly of pressure vessels (86). Each chamber (86) has a frangible blowout diaphragm (104) to blowout into the manifold when the chamber propellant is initiated. The other ends of the chambers are enclosed and each is connected to a respective initiator (100).

A molded ejection seat having a rocket motor propulsion system integrated with the seat, comprising: a seat body having upper and lower side walls, a front wall between the lower side walls, and back wall portions extending generally between the upper and lower side walls; a backrest panel removably secured to the body to form a front thereof and to extend generally between the upper side walls to increase torsional rigidity of the seat structure by closing a torque box formed with the upper side walls, back wall portions, and the backrest panel; a rocket motor propulsion system being incorporated within the body below the upper side walls within the lower side walls, generally rearwardly of and below the backrest panel, and generally rearwardly of the occupant sitting area; and a rocket nozzle being connected to the propulsion system and being fitted generally within the lower back seat periphery and the seat envelope; the rocket motor propulsion system being integrated into the body as it is being formed; the rocket motor propulsion system being formed as a consolidated honeycomb-type assembly of pressure vessels which utilize the strength of shared pressure containment walls to reinforce the lower part of the molded seat body and eliminate concentrated rocket thrust load transfer points and create an efficient structure for load transfer and material utilization; the honeycomb assembly being comprised of a series of individual cylindrical propellant chambers, each chamber being generally adjacent to other chambers; and each chamber being interconnected to a manifold connected to the rocket nozzle.
