DE1923834B2 - Multi wing skimming craft - is trimmed by adjusting front wing angle and rear wing longitudinal setting - Google Patents

Abstract

A skimming craft pulled by another suitable craft (11) has wings which lift it due to the air cushion trapped underneath. The craft has a support frame in which the wings are fitted, while steering stability is provided by delta shaped tailplanes raised over the rear of the frame. To trim the craft for different loads, without any drastic changes of shape, the front wings (2) are tilted about their axes to alter the uplift. The rear wings (3) can be tilted to the selected angle and can also be displaced away from the front wings using a rack and pinion control (25, 30). The centre of lift of the craft can thus be altered without any special reconstruction.
