EJECTION SEAT Russian patent published in 1998 - IPC

FIELD: aeronautical engineering; device for emergency escape; aerobatic aeroplanes of tactical aviation. SUBSTANCE: ejection seat includes cruising booster, control powder rocket engines with nozzles oriented relative to center of mass of seat, control system electrically connected with roll-angle sensor 7; seat is also provided with velocity sensors 8 and seat position sensor 9, and powder gases pressure sensors 6 showing pressure of powder gases in control engines; these sensors are connected with control system 5. Control engines are provided with drives 4 and are secured on side panels for turn relative to their longitudinal axis; drive is electrically connected with two-circuit control system; output of roll-angle sensor 7 in first circuit is connected with first input of logic signal converter through threshold element and first inputs and outputs of first circuit of AND and OR gates. Logic signal converter is used for conversion of logic signal into electric pulse; first output of this converter is electrically connected with starboard control engine. Output of threshold element is connected in parallel with second input of logic signal converter through first inputs and outputs of second circuit of NOT, AND, OR gates; second output of logic signal converter is electrically connected with port control engine. Output of roll-angle sensor 7 in second circuit is connected with inputs of second and third adders through first inverter, first switch, first adder and computer connected in series. Outputs of second and third adders are connected with drives. EFFECT: enhanced reliability. 3 cl, 5 dwg
