Brabazon - On tow to the test area

Brabazon - On tow to the test area

G1268. Being towed to the engine run test area, nacelle doors open, note steam train passing power station behind. The sound of eight Centaurus engines on song must have been a delight to an aviation engineers ears. To the local housewives a pain in the neck. There were three stages of the power plant ground testing.
Phase 1 - Vibration testing of the propellor shafts and employed dummy propellors and electric motors to simulate the engines.
Phase 2 - Involved a test rig with two Centaurus engines geared together in order to test the gearbox and adjacently mounted engines.
Phase 3 - Involved a complete replica of the power plant complete with accessories mounted within a wing section.

The twin Centaurus power unit completed its ARB type test in June 1948, after more than 1200 hours of development running which had started in 1946.
