FIELD: aviation.
SUBSTANCE: group of inventions relates to aircrafts made according to aerodynamic schemes "duck" or "tandem". Aircraft comprises interconnected front and rear bearing surfaces equipped with lifting force control devices functionally dependent on aircraft attack angle variation. Derivative of lift factor by aircraft angle of attack is positive for rear surface and negative for front. Aircraft attack angle variation sensor comprises front and rear surfaces with fastening hinge between them. Derivative with respect to the angle of attack of the coefficient of lift of the rear surface exceeds the derivative of the front surface by not less than one and a half times.
EFFECT: group of inventions is aimed at providing longitudinal stability of aircraft by reducing influence of horizontal gusts on aircraft lifting force.
