The choice of a power unit for large hovercraft is dictated by many of the factors which affect aircraft, but also some of the considerations applicable to ships. Power to weight ratio is an important factor; overall size is equally important but perhaps the overriding consideration is that most hovercraft operations are over sea ways and likely to be in economic competition with ships. This paper reviews the history and highlights the problems associated with the use of gas turbined-powered hovercraft. In particular, the author discusses the effect of salt water spray and the measures taken to control it. Particular reference is made to the endeavors on the part of the craft designers to provide a filtration system to cope with the salt laden atmosphere and the problems presented to the engine designer necessitating the use of different materials with greater corrosion resistance.
