METHOD OF TAKE-OFF OF AIRCRAFT Russian patent published in 1999 - IPC

FIELD: deck aviation. SUBSTANCE: prior to take-off, cruise engine is set in working mode at maximum afterburning thrust which is no less than 0.5 of aircraft take-off weight. This mode is maintained till maneuvering speed has been attained. Take-off acceleration includes pitching acceleration in final acceleration run at interaction with curvilinear spring board. Take-off acceleration during run over entire length of spring board is effected at distance of no less than 8 distances between front and main legs of aircraft at monotonic rise of normal g-load to no more than 3 g at parabolic rise of pitch angle to 12-16 deg at lift off spring board. Stabilizer is turned from position at negative angle of attack in getting on spring board to position at positive angle of attack. After lifting off spring board, stabilizer is turned to position of minimum positive angle of attack sufficient for rise of angle of attack of aircraft to magnitude corresponding to increasing speed of flight. EFFECT: reduced hunting of aircraft when running on spring board. 3 cl, 2 dwg
