The reverse-thrust ratio (ratio of backward engine thrust to forward reverse thrust) can be as high as 84%. [6] However, this result is obtained with a cowl to attach air flow in a 7° angle and a large enough "target" (deflector door) installed. A reverse-thrust ratio of 55% can be reached on a simple target without the cowl. [7]
The N.300 Naviplane was a French 30-ton multipurpose Air-cushion vehicle built by SEDAM (Société d'Etude et de Développement des Aéroglisseurs Marins) for the Naviplane series of Aéroglisseur . This was a series of multi-skirt hovercraft built by SEDAM using and developing the skirt designs by French engineer Jean Bertin .
Jean Bertin was an early advocate of the hovercraft, and had built a series of multi-skirt transport vehicles for the French army known as the "Terraplane" in the early 1960s. In 1963, he showed a model of a vehicle similar to the early Hovercraft Development concepts to SNCF .
