摘要

以无限薄翼型的非线性理想振荡模型为例,区分了推力系数的三个分量:惯性、循环和涡。研究了每个获得的部件对牵引力的贡献,并解释了不同类型振荡下机翼牵引力形成的机制。揭示了惯性循环原理是翼推进工作的基础。涡尾对牵引力的感应效应较小,且为负。

INERTIAL-CIRCULATING PRINCIPLE OF SWIMMING AND FLIGHT OF HYDRO- AND AEROBIONTS. PART 2
For the case of modeling in the nonlinear ideal formulation of oscillations of an infinitely thin profile of the wing-propulsion, three components of the thrust force coefficient were distinguished - inertial, circulating, and vortex. The contribution to the traction force of each of the obtained components is investigated and the mechanisms of wing traction force formation at different types of oscillations are explained. It is revealed that the inertial-circulating principle underlies the work of the wing-propulsion. The inductive effect of the vortex trail on the traction force is small and negative.
