Abstract

1293703 Propelling ships by water jets COMMISSARIAT A L'ENERGIE ATOMIQUE 19 April 1971 [18 March 1970] 24575/71 Addition to 1238995 Heading B7V [Also in Division F1] The marine craft propulsion unit 10 described in the parent Specification has a feed comprising a receptacle 12 containing a substance in liquid and vapour phases, the vapour pressure being greater than the water pressure at the average operating depth of the propulsion unit and at the minimum temperature encountered by the propulsion unit. The lower portion of the receptacle, which is occupied by the liquid phase, is connected by a valve 16 and a heat exchanger 14 to the emulsifier of the propulsion unit 10. In the embodiment designed to operate at shallow depth the substance is propane or ethane or carbon dioxide gas. Liquid carbon dioxide or liquid nitrogen is used to operate at depths greater than 100 metres.
