Avon Turbine engine pre-test - LOUD

Quick run up to check instrumentation, and then a shutdown of a Rolls Royce Avon at the S&S turbines outdoor test cell in Fort St John, BC.

We could not take it past idle because ice was beginning to form in the intake, and this engine does not have anti-icing ability.

what is the sound at 0:17

@Dc9fan That is the compressor bleed valve on the start cart opening to allow air to be fed to the starter on the big engine. The start cart is a small turbine engine, and it has to get up to 104% rpm before it will allow its bleed valve to open. The actual noise you hear when this happens is from the exhaust of the air turbine starter.

I have posted a video of this starter in action.

Where is STARTER in this angine? I can't see it?

@digitalblue9000 This engine is usualy started in its installation by a hydraulic motor connected to the main rotor at the front.

For our test we designed and built a torque tube mount so we could use the air turbine starter from a GE LM1500. It has internal reduction gearing and worked well.

It comes into view at 2:22.

It is fed air at 25 - 30 psi from the yellow start cart.

Other Avons are electric start, and I have some vids of those posted.

@digitalblue9000 When you first see the starter at 2:22... the air hose from the start cart has already been disconnected by Moto-Steve. He's super fast and efficient.
