| Number | Title | Issue Date |
| 5272422 | Head equipment with articulated arm A head equipment comprises a component such as a helmet connectable to the head of a wearer and movable by the wearer in a limited field, with at least five degrees of freedom. It comprises an arm constituted by articulated segments giving the component a... | 12/21/1993 |
| 5133515 | Pitch stabilization system for an ejection seat A pitch stabilization system for an ejection seat includes a gyroscope rotor assembly having a pinion gear attached to two rotor wheels. The rotor assembly is mounted with a geometry to precess in response to change in the pitch rate of the seat. Precessi... | 07/28/1992 |
| 4846421 | Adaptive control system for crew escape devices An escape device such as an ejection seat system (10) has a propulsion system (42) that accelerates and changes the angular orientation of the device. The system (10) includes sensors (54) for determining certain parameters associated with device altitude... | 07/11/1989 |
| 4749153 | Ejection seat stabilizing apparatus and method Inner catapult tubes (8) of aircraft (2) are pivotably mounted on the upper rear portion of ejection seat (12). When they separate from outer catapult tubes (4), tubes (8) pivot upwardly and rearwardly to form stabilizing booms (8). A drag device (30,30',... | 06/07/1988 |
| 4749154 | Ejection seat having combined catapult/rocket motor providing selectable thrust An aircraft ejection seat (10, 120) having a combined catapult (46, 122) and rocket motor (88, 90, 130, 132, 142, 144) in which the amount of rocket thrust is selectable. An outer catapult tube (46, 122) forms a seat support structure. In the outer catapu... | 06/07/1988 |
| 4721273 | Life-threat assessment and control command for aircrew escape systems A crewmember (12) is positioned within an ejection seat or other escape device (10). The escape device (10) is ejected from the aircraft or other flying vehicle when it is desired to effect an escape. At the start of ejection, the altitude, sink rate and ... | 01/26/1988 |
| 4673147 | Programmable ejection seat system A programmable crewmember emergency ejection system is disclosed which will eject the crewmember expeditiously from a disabled aircraft, while at the same time assuring that the crewmember will not be subjected to forces that are beyond crewmember toleran... | 06/16/1987 |
| 4667903 | Ejection seat having roll thrusters with propellant chambers in the inner catapult tubes 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... | 05/26/1987 |
| 4395001 | Attitude selective aircrew escape control A line cutter or discharge valve responsive to aircraft attitude is posited on an aircraft ejection seat to interrupt the gas initiated sustainer rocket system. During inverted ejections, the cutter or valve will either sever or discharge pressure from a... | 07/26/1983 |
| 4036456 | Rocket catapult with direct mechanically actuated ignition of rocket motor An improved rocket catapult is disclosed for use in aircraft ejection systems permitting direct ignition of the rocket motor by a mechanically-actuated igniter situated in proximity to the rocket motor grain and which is actuated when the rocket motor has... | 07/19/1977 |
| 3979088 | Rocket catapult A rocket catapult ejection system for a seat-occupant mass of a disabled craft in which the rocket motor has an annular nozzle throat defined by a spherical pintle and an adjustable nozzle housing. Axial adjustment of the nozzle housing will displace the... | 09/07/1976 |
| 3949676 | Load actuated electro-ignition circuit switch An igniter mechanism for a rocket motor utilized for towing a load or extting an air crew member from a disabled aircraft. The mechanism operates whenever a sufficient force is exerted on the tow line to shear a pin allowing closure of the switch. Electr... | 04/13/1976 |
