Abstract
A gas-cushion vehicle is provided with one or more fans for supplying cushion air to the cushion space beneath the vehicle, and an additional, 'passive' fan, the outflow of which varies according to changes in cushion pressure, whereby additional air is supplied to the cushion space as cushion pressure tends to decrease, and a backflow of cushion air takes place through the additional fan as cushion pressure tends to increase.
