The velocity potential on triangular and related wings with subsonic leading edges oscillating harmonically in supersonic flow

Abstract

The method developed by C. E. Watkins and J. H. Berman in N.A.C.A. Report 1099 and N.A.C.A. Technical Note 3009 is used to obtain the velocity potential on a triangular (or related) wing with subsonic leading edges oscillating in a supersonic flow. A symmetric mode of oscillation is considered which is represented by a polynomial expression in the co-ordinates of the points of the wing. This polynomial expression is of higher degree than those of the above two papers. The results enable the first few terms of a power series in frequency for the velocity potential to be obtained.
