An improved and simplified model for the Heave-Pitch dynamics of the XR-3 CAB Surface Effect Ship is developed for constant speed operation. The nonlinear equations of motion are linearized about the steay-state operating point. Time-domain validation is accomplished by comparison with the 6 DOF model. A signal flow graph of the craft dynamic is developed and Masons Gain Rule used to determine the characteristic S-domain polynomials describing the crafts vertical plane dynamic behavior, with Bode Plot analysis included. Conclusions are drawn and recommendations for further study are made. Author
