A – The use of a single horizontal axis fan with a splitter plate in its slipstream was pioneered by the author and two UK Hoverclub Members back in 1972. The splitter was positioned across the lower part of the fan duct. It takes the form of a chord of the diameter of the fan duct (forming a segment of a circle) which represented approximately 30% of the fan air. This portion of air is directed beneath the craft to form the air cushion on which the craft rides.
