An engineering code has been developed for estimation of longitudinal aerodynamic coefficients of launch vehicles with strap-on boosters. The code, which incorporates data from analytical/empirical methods, CFD analysis, wind tunnel tests and similar codes, has been used for parametric analysis of the effects of geometric characteristics and flow conditions on longitudinal force coefficients of a generic launch vehicle. Results indicate suitable accuracy for the purpose of preliminary aerodynamic design, within a nominal range of flow conditions.
