GHOST JET ENGINE

LONDON, Feb. 2'o.

Details of the ghost jet engine, one of the world’s most powerful aero engines, has been reelased by its builders, De Havillands. The ghost is the second gas turbine to be announced in the De Havilland range, and is similar in general to the Goblin engine, but very much more powerful. (The Goblin was the first jet engine to pass British official type-approval tests). Although only 53 inches in diameter (three inches 1 more than the Goblin) it develops a static thrust of 5,0001 b as against the Goblin’s 3,000. Some impression of its capabilities may be gained from the fact that at 600 miles per hour at sea level its power output corresponds to 12,000 horse power from a propeller driving engine. Further developments will lead to a still higher level. Design work on the ghost engine was begun in 1943. By virtue of its suitability to a diverse range of installations and the fuel economy which has been the major design requirement from the first, the ghost is recognised as an engine with a prospect of wide application in the whole field of jet-propelled flight.
