METHOD FOR ACCELERATED TAKEOFF OF AIRPLANE Russian patent published in 2009 - IPC B64C13/00 G05D1/00 

FIELD: aviation.

SUBSTANCE: invention is related to method for airplane control in case of takeoff. Method consists in preliminary definition of airplane speed that characterises speed of front wheel take-off, at which front wheel take-off should start during takeoff at the end of acceleration phase, during which airplane speeds up and accelerates, and range of speed values control, inside of which front wheel takeoff speed should be located. At that pitch command is applied to airplane for assistance to takeoff, which deviates reversible horizontal stabiliser at the angle of previously established value, in which comparison speed is arbitrarily selected prior to acceleration phase, within the range of speed values control, lower than the speed of front wheel takeoff, and for this comparison speed previously specified value is set for deviation angle of reversible horizontal stabiliser at least depending on longitudinal position of airplane gravity center during takeoff. During acceleration phase airplane speed is measured, variable deviation is continuously defined, which exists between measured speed and comparison speed, and variable correction of flight assistance pitch command is carried out in compliance with speed deviation.

EFFECT: provision of uniform behavior of airplane during takeoff.
