Development and Time Domain Validation of a Low-Order, Constant Speed, Pitch-Heave Model for the XR-3 Surface Effect Ship.

Abstract

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 Mason's Gain Rule used to determine the characteristic S-domain polynomials describing the craft's vertical plane dynamic behavior, with Bode Plot analysis included. Conclusions are drawn and recommendations for further study are made. (Author)
