Generalized aerodynamic forces on a flexible plate undergoing transient motion in a shear flow with an application to panel flutter


Journal Article

A theoretical solution to the title problem is obtained. Unlike previous solutions in the literature, the present method allows for finite plate dimensions and continuously varying mean velocity and temperature profiles. A computer program has been developed to calculate the required aerodynamic forces for boundary-layer profiles. These forces are then employed in a nonlinear flutter analysis previously developed by the author. The theoretical flutter results are compared with the experimental data of Muhlstein, Gaspers, and Riddle and generally good agreement is obtained. Other physical problems to which the present aerodynamic analysis is relevant include, 1) stabilization of viscous boundary layers by flexible walls, 2) sound wave propagation through shear layers, and 3) shear layer effects on control surface aerodynamics at supersonic speeds. © 1971, American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
