ABSTRACT:
An ejection seat (10) having roll thrusters (38, 40, 112, 114) and propellant chambers in the inner catapult tubes (44, 46, 124, 126). The roll thrusters (38, 40, 112, 114) are adapted to roll the seat (10), when ejected from an inverted or unsatisfactory attitude to an upright proper attitude. Solid propellants (44, 46, 128, 130) within the inner catapult tubes are to be ignited after the seat is being ejected. There is a roll thruster valve housing (36, 110) connected to both roll thruster nozzles (38, 40, 112, 114) and to both inner catapult tubes (24, 26, 124, 126) so that propellant gas may flow from both catapult tubes to both nozzles. The check valve (52) in each inner catapult is operable to open during ejection by ejection gas and is operable to close by the roll thruster gas when the roll thruster propellants are ignited. The check valve system modulates the catapult gas pressure during ejection, prior to roll thruster propellant ignition.
