Аннотация: The aerodynamics of flapping wings, and airfoils, wasstudied in many works. In [1], it was shown that sinusoidallyheaving of an airfoil can produce thrust and lift. Morecomplex combinations of heaving, pitching, and rotation,were studied in the works [2]-[4] and others. Theyconsidered the motion of the airfoils obeys a given law.These works show that correlation between these kinds ofmotion plays a significant role. The optimal values of thephase shifts exist. It is of interest whether the phase shift willprovide thrust and lift if the motion of one of the degrees offreedom will occur under the action of hydrodynamic forcesand elasticity.In this paper, we consider the determined heaving andpassive pitching of an airfoil on an elastic hinge.Yaroslav Dynnikov1*, Galina Dynnikova1 , Sergey Guvernyuk1, Tatyana Malakhova11Lomonosov Moscow State University, Institue of Mechanics,Michurinsky pr. 1, 119192, Moscow, Russia
