Study of heave acceleration/velocity control for the surface effect ship.

MetadataShow full item record
Through the use of simulation studies of the SES 100-B, a heave controller is designed, tested and coupled with a speed control. Holding the thrust parameter constant, this control system functions by variations of the plenum pressure only and is based on controlled venting by louvers to dampen heave accelerations while the main fan rpm is changed to maintain the minimum draft necessary to hold the speed constant at or near the initial value.
