Abstract
2D modeling of flapping flight is performed using DNS equations, the wing is simulated by an ensemble of Lagrangian particles. The simulation is carried out in two planes – parallel and orthogonal to the flight direction. The Golubev vortex street, which creates thrust, is reproduced; the meaning of figure-of-eight kinematics is clarified; it is shown that the vortices induced by the wing stroke eliminate the flow separation. It has been established that the use of folding wings reduces the energy consumption of birds by three times. The aerodynamics of a cyclocopter model with hybrid kinematics has been studied.
