Abstract : The NASA Ames Research Center developed panel code (PMARC) is investigated to explore its suitability for aerodynamic missile design. To this end, PMARC is first assessed by applying it to several problems for which other solutions and experimental data are available, i.e., steady flow past a wing-body configuration, delta wings, biplane wings, wings in ground effect, and unsteady flow of pitching and impulsively started wings. Good agreement is found in all cases. PMARC is then applied to two missile configurations. Again, encouraging agreement with available experimental data is found provided the wake shedding from the missile body is modeled properly.
