Note: This is a sub-section of De Havilland

A single-shaft turbojet developed in two main forms:

  • the DGJ.2 Mk 101 rated at 7,1001b for the Blackburn NA.39; the engine could supply an enormous flow of bleed air to the high-lift devices of that aircraft.
  • the DGJ.10 for the Bristol 188, rated at 10,0001b dry and 14,000 with reheat, designed for flight at Mach numbers of over 2.5.

The front end is fabricated in steel and titanium, the oil is cooled by the fuel, and the control systems of the engine and 2,000°K afterburner provide simultaneous regulation of compressor bleed, convergent/divergent nozzle geometry and fuel metering to the engine and afterburner.[1]
