Test Run of Rolls Royce Artouste APU Engine

Test Run of Rolls Royce Artouste APU Engine. This unit originally came out of an RAF VC-10. The turbine disc glows a bit under load even though the TGT is within limit. I think too much air may be bypassing the air-delivery butterfly valve on the combustion chamber. Nice little engine!!
