Validation of the Nonlinear Six Degree of Freedom Mathematical Model of the XR-3 Captured Air Bubble Surface Effect Ship in Calm Water.

Abstract

The non-linear, six-degree-of-freedom, mathematical model of the XR-3 captured air bubble surface effect ship is validated by comparison of measured testcraft performance with computed variables in the digital computer simulation. Data processing methods implemented on hybrid and digital computers are presented. Improvements are made on the structure of the mathematical model of the XR-3 by program subroutine modifications and justification is given for the changes made. Close agreement is obtained between measured and computer simulated variables over a variety of operating conditions in calm water.
