Addition of an Arbitrary Body Analysis Capability to the Boeing TEA 236 Finite Element Computer Program.

Abstract

The Boeing TEA 236 computer program, used to calculate wing pressure distributions of wing-body configurations, is examined. Small perturbation potential theory, as used by the program, is reviewed. The method used by the TEA 236 in the analysis of a fuselage of circular cross-section, in calculating wing pressures, is examined. The capability to analyze an arbitrary body cross-section is added by employing at least-squares fitted cosine series to more accurately describe the actual body cross-section. Comparison is made between C-5A wind tunnel data, computed data obtained from the TEA 236 using its unmodified circular body routine, and computed data obtained from the TEA 236 using the analytical body description technique developed in this study.
