dc.description.abstractThe response of an elastic membrane to an external flow and its significance with regard to aerodynamic drag enhancement technique is discussed. It is shown that because the response of an elastic membrane to an external flow and the development of Kelvin-Helmholtz instabilities due to the relative motion between the atmosphere and the spacecraft, the flapping of the membrane will translate in a ulsating pressure onto the walls which added to the skin drag friction will increase the apparent drag force exerted by the surrounding media, i.e, a drag enhancement technique. Utilizing a simplified linear and inviscid stability analysis an estimate for the response of the membrane as well as the drag enhancement was obtained. The technique could be particularly interesting for descent spacecraft vehicles in planets with reduced atmosphere as Mars.
