The de Havilland Ghost was a British turbojet engine which served as the power plant for the de Havilland Venom and Comet, a fighter bomber and a commercial aircraft respectively. In Sweden, it was modified to power the Saab J 29 Tunnan combat plane as it was known as the Svenska RM2B in the Scandinavian country, being produced there under license. Approximately, 2,500 Ghost turbojet engines were produced between 1948 and 1960. It had been developed from the de Havilland Goblin, which powered the Vampire; the second British jet fighter in service with the RAF.
Technical Description
Originally known as the Halford H-2, the de Havilland Ghost was a single-stage, axial-flow turbojet engine that ran on aviation turbine fuel. It was composed of one single-stage, centrifugal-flow compressor, ten combustor chambers, and one single-stage, axial-flow turbine. A centrifugal-flow compressor is a machine in which the air flow is radial and is compressed by radial acceleration. The engine could deliver a maximum thrust of 5,300 pounds during take-off; 6,167 pounds in the Swedish version. The turbine inlet temperature reached 1,400 degrees Fahrenheit (760 degrees Celcius).
