Abstract:

The Barrowman Method is an accurate, low-cost algorithm for the calculation of aerodynamic parameters for rockets. The method has been modified to allow the use of airfoiled wings and fins with control surfaces and to include the effects of downwash from the wings on the fins. It has been shown that interdigitation of the wings and fins significantly reduces the downwash. The Modified Barrowman Method has been applied to PDAMS and compared to wind tunnel results. An aerodynamic model of the OPDAMS vehicle was generated.
