    Abstract

    An assessment has been made of the usefulness of an existing code for predicting the longitudinal aerodynamic characteristics of wing-body combinations at high angles of attack. Several comparisons with experimental results13; are made for wing-body, wing alone and body alone cases at subsomc speeds. These comparisons indicate the need for better representation of body vortex flow for improved prediction. The wing loads are predicted well by the potential theory with Polhamus suction analogy.
