An airfoil is operated in combined plunging and pitching motion to generate a thrusting jet in a still air environment. The device serves as a simple, generic and two-dimensional model for hovering flight of small birds and insects. When properly tuned the device produces very large average thrust coefficients. The vortical signature of the tuned jet is a vortex street with reverse sense of rotation as the vortices of a Karman street. Keywords: Unsteady aerodynamics; Separated flows; Dynamic stall. (EDC)
