The Effect of Camber on Force Generation in Leading Edge/Trailing Edge Switching Hovering Mode
The leading edge/trailing edge switching mode has been identified as advantageous because it allows airfoils to have camber. In this paper, the effect of camber was investigated in a series of two dimensional, unsteady, laminar computations with dynamic mesh for plunging and pitching airfoils operating at Reynolds numbers from 100 to 2,500 and reduced frequencies of 0.5 to 2. Vortices are identified shedding from the edges. Lift is created by a downward directed wake and by rotational circulation. Camber was found to increase lift at every Reynolds number and reduced frequency in this stu
