Asymptotic Inviscid Theory of Lift on Slender Bodies of Revolution.

Abstract

The viscous theory of lift on bodies of revolution developed under previous contract (ONR N00014-81-C-0240) is simplified for slender bodies of revolution. The resultant inviscid integral equation is solved in closed form for a prolate spheroidal body. An explicit representation of the eigenfunction is obtained and numerical results for the load distribution are compared with results of conventional slender body theory. The magnitude of the eigenfunction is estimated to be of order 1 by correlating with experimental data on the USS Akron. The qualitative features of the load distribution are in much better agreement with experimental data than the distribution obtained with the equivalent base area concept applied to conventional slender body.
