An Aerodynamic Analysis of Deformed Wings in Subsonic and Supersonic Flow.
Abstract
The aerodynamic loading for deformed wings in both subsonic and supersonic flow has been under study for the past year. The basic solution technique falls into the potential flow category with appropriate restrictions. A lifting surface kernel function formulation is used for both subsonic and supersonic flow and results are obtained which agree very well with experimental data. Subsonic solutions for deformed wings with deflected elevons are obtained in a semi-closed form summation manner. Cases under study which include gaps between the elevon wings are as yet incomplete but is presently being pursued. For supersonic flow, a modified Evvard solution forms the basis for the planar wing cases and vorticity paneling is added to account for local deformations in the wing mean camber surface. Results are obtained which agree very well with experimental data. The gapped elevon cases for supersonic flow is also analyzed and preliminary results have identified thickness effect, as being very important, at least for small elevon deflections. (Author)
