Navy Tests Gas Turbines In Gunboat -- HMS Grey Goose at speed in the Nab Tower area during Channel trials today (Tuesday).
HMS Grey Goose, renowned as a steam gunboat during World War II, is new undergoing rigorous trials in the English Channel as a floating test bed powered by two experimental Rolls-Royce RM.60 marine gas turbine engines.
The engines transmit their power through controllable pitch propellers which obviate the use of reverse gearing.
The gas turbines are expected to give total power about 35 per cent greater than that of two 4,000 h.p. steam turbines the ship originally had. July 05, 1955. (Photo by Reuterphoto).
