METHOD OF PREPARATION OF AIRCRAFT FOR TAKEOFF FROM FLYING-OFF APRON OF AIRCRAFT CARRIER Russian patent published in 2005 - IPC

FIELD: marine aviation; preparation of aircraft for takeoff from flying-off position of aircraft carrier.

SUBSTANCE: proposed method includes arresting the aircraft on flying-off apron, mounting the gas-deflecting shield at angle of 50-70° relative to surface of deck, attaining the "maximum boost" mode of engine, checking the aircraft readiness for takeoff, transmitting the information on readiness to fly off and releasing the lock. If aircraft is equipped with engines provided with swivel nozzle, swivel nozzle control mode shall be switched-on after arresting the aircraft. Then, nozzle is deflected upward through angle of 14-18° which is maintained for 0.7-1 s at "maximum boost" mode and is reduced to 6-9° in 6-10 s and is kept in this position for 6-8 s. At the moment of releasing the lock, nozzle is returned to neutral position. Gas jet of engine is reflected from gas deflecting shield due to reduction of reverse flow of gases sucked by air intake.

EFFECT: enhanced efficiency and reliability.
