Abstract
A rocket motor is disclosed that is suitable for use with an ejection seat. The rocket motor includes a combustion chamber, and has a plurality of spaced apart outlets arranged in fluid communication with the combustion chamber, to allow the passage of exhaust gases upon ignition of a propellant within the combustion chamber. Each exhaust outlet is arranged to direct the exhaust gases along respective fixed lines of thrust. The arrangement is such that the resultant thrust generated by the rocket motor acts along the line non-parallel with at least one of the fixed lines of thrust so as to direct the rocket motor along the curved trajectory. The secondary outlets may be smaller than the primary outlets and are selectively closable by valves.
