Abstract : IN A PREVIOUS REPORT (AD-261 457), the radom roll response of a hovering submarine to confused directional seas was determined using the method of generalized harmonic analysis. Roll damping was caused by a linear roll stabilizer gyroscope. This analysis is generalized to include linear natural damping. Nonlinear natural damping and nonlinear gyro damping are taken into account also using the method of equivalent linearization. This analysis is then applied to determine initial conditions due to submarine roll which are imposed on a missile launched from the submarine. The subsequent missile response is then obtained.
