Ground Running The de Havilland Supersonic Turbojets In The New Bristol 188 All-Steel Research Aircraft

Ground Running The de Havilland Supersonic Turbojets In The New Bristol 188 All-Steel Research Aircraft

Go back to the map or view all the records from this map.

G1849. Here seen undergoing test running at the British Aircraft Company's airfield at Filton, are the two de Havilland Gyron Junior DGJ10 reheated turbojet engines which powered this high speed research aircraft. Designed to operate at speeds of over Mach 2.5. Each of these engines develops 14,000 lb static thrust at a reheat combustion temperature of 2000 degrees Kelvin. The engines are connected to a Palouste starting rig, which is a small jet engine that is used to start the engines on the aircraft. Compressed air will go through the pipe you can see and will rotate the compressor, then as air is sucked in and they can start the engines, usually when rotational speed approaches 34%. You can also see the leads from the ground battery supplies. Whilst the aeroplane is being started the men watch wearing ear defenders as the noise would be tremendous, The engineer in the cockpit will note down engine parameters as he starts up an runs the engines up to max. Checking the acceleration time, in seconds, from flight idle to max rpm.
