Abstract:

Determined in this study are the position and rotary derivatives of a V-wing moving above a solid screen. This problem is interesting for a number of problems in the dynamics of vehicles which use the screen effect during motion. Studied is a thin V-wing of rectangular plan shape above a solid wall. The induced velocities are considered low, while the vorticity beyond the wing lies in planes corresponding to the planes of the wing. These assumptions are realized at small angles of attack, relatively great distances between the wing and surface, and when the amplitudes of the harmonic oscillations are small. The condition of equality to zero of the normal velocity component of liquid particles should be satisfied on the solid screen.
