【 摘 要 】

In the paper we investigate the forces that act on the profile when profile starts suddenly to accelerate. It was proved that that sudden jump of acceleration cause sudden jump of the lift force. The peaks of force jumps do not depend on Reynolds number. To investigate that phenomena it was carry out the numerical simulation using the vortex particle method.
