Airborne Auxillary Power Plant
The control box allows the Nimbus engine to be started and ground run.
The gas generator core of the Artouste is very similar of the Nimbus, minus the axial compressor stages. The engine was designated 'Airborne Auxillary Power Plant AAPP', and was designed to supply compressed air for main engine starting and to drive a 40kVA alternator. The unit was mounted in the starboard wing root of an RAF Victor Bomber.
Specifications:
Single stage centrifugal compressor, pressure ratio 3.6:1
Annular combustion chamber with fuel injection via holes in hollow rotor shaft.
High energy torch igniter.
Two stage axial turbine.
Power output 1.65lb/s at 37.7PSI (0.75kg/s at 2.6bar) or 60kVA at 0.8PF
(Equivalent air output power is approximately 200hp).
Shaft speed 34000 rpm.
The manual shows the general assembly of the unit:
To date (February 2002) no work has been done on this unit, but the engine looks in good internal condition. The alternator is missing, but a blanking plate if is ftted in its place.
