Abstract : New methodology has been added to the NSWCDD Aeroprediction code to permit the distribution of the local linear and nonlinear aerodynamic loads along the body length and over the wing and tail lifting surfaces. The new techniques extend to both the PHI = 0 deg and PHI = 45 deg roll positions and to both windward and leeward lifting surfaces in the 45 deg orientation. The local loads are integrated to get the distribution of the shear and bending moments for use in structural analysis and design. Navier-Stokes CFD computations for the Seasparrow missile were used in the development of these extensions to the code and in validating their effectiveness. In general, good agreement with the CFD results is obtained.
