FIELD: aviation.
SUBSTANCE: aerodynamic control surface consists of a front and a rear links having a common rotation axis. The rear link is made with axial compensation. The deviation angle of the front link is proportional to the deviation angle of the rear link with a proportionality factor from 0.6 to 0.8. Between the front and rear links of the control surface there is a profiled slit. The front and rear links of the control surface can be designed to be deviated as a whole by the same angle.
EFFECT: increased efficiency and reduced hinge moment of the control surface.
