Abstract : The oscillation envelope for a spinning reentry body is computed for large angles of oscillation by an approximate method, the validity of which rests upon near constant velocity and near straightline flight. It is found that initial conditions of entry are of great importance in determining behavior at lower altitudes. Oscillatory solutions are discussed which are compatible with the steadystate nonzero angle solution. The only damping mechanism assumed is the heteroparametric (''q tightening'') resonant frequency shift characteristics of reentry flight. A numerical example illustrates the results. A computer program is available which solves the equations derived herein, under the assumptions detailed in the discussion of the example. (Author)
