Turbomeca Palouste

[1] Designed purely as a compressed air generator, the Palouste was mainly used as a ground-based aircraft engine starter unit.

Originally conceived as an aircraft ground support equipment starter gas generator, it was used also as propulsion for the Sud-Ouest Djinn and other tip-jet powered helicopters.

The Palouste was a very simple unit, its primary purpose being to supply a high flow rate of compressed air to start larger jet engines such as the Rolls-Royce Spey as installed in the Blackburn Buccaneer (this aircraft having no onboard starting system).

Several British naval aircraft were adapted to carry a Palouste in a wing-mounted air starter pod installation to facilitate engine starting when away from base.

The builder modified the engine to include a primitive afterburner device and noted that pitch changes which occurred during braking and acceleration caused gyroscopic precession handling effects due to the rotating mass of the engine.
