摘要: Using a wedge shaped camber and classical Goland beam model, we in- vestigate the effect of thickness on flutter speed in an inviscid airflow setting. We explicitly derive Possio equation corresponding to aerodynamic poten- tial flow which relates pressure jump downwash (normal velocity wing). The solution this boundary value problem is obtained M = 0 1 cases, used compute lift moment forces solve for structural dynamics. find that case signifies incompressible flow, increases with thickness. On other hand, sonic demonstrates opposite pattern decreases
