摘要: Abstract : The incorporation of simplified hover wake models into the comprehensive rotorcraft analysis code C A M R D is described and examples are given on their use. axisym metric models, in which vortices represented by either straight lines or rings, a more generalized form free R.T. Miller at MIT, with geometry also able to be prescribed. Incorporation has allowed access tabular representation airfoil section characteristics as functions angle attack Mach number, broadened range rotor include model that does not have convergence problems existing when used for hover.
