Abstract:
The oscillation envelope for a spinning re-entry body is computed for large angles of oscillation by an approximate method, the validity of which rests upon near constant velocity and near straight-line 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 steady-state non-zero angle solution. The only damping mechanism assumed is the heteroparametric q tightening resonant frequency shift characteristics of re-entry 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
