<p>This disclosure relates to controlling a surface effect vehicle. Pressure transducers sense the air pressures at the output of the vehicle's blower fan and in the vehicle's plenum chamber. An analog summer generates a signal indicative of a relationship between the two pressures and the signal controls a first servo mechanism which regulates the volume air which enters the blower fan. The control system automatically maintains a constant pressure in the plenum chamber, which prevents vehicle oscillation in the vertical and other modes, thereby eliminating instabilities. In addition a second servo mechanism operates in conjunction with the first servo mechanism system to allow control by manual command.</p> |
