A comparison of test runs of two variants of the same engine.
The Orenda 14 turbojet is the engine that powers the Canadair Sabre 6, a licence built Canadian adaption of the North American F-86 Sabre jet fighter, from the 1950s, and saw much action if the Korean war.
They still are flying and have many admirers at air shows.
The OTF-3 is the industrial gas generator created by redesigning the 14; all accessories are stripped off except the oil pump, and the jet acceleration nozzle at the back is deleted. It is now a gas generator, and runs on natural gas.
It will supply gas to drive a separate power turbine, which will drive an electrical generator through a reduction gearbox, which will reduce its running speed of 7200 rpm down to 3000 or 3600 rpm depending on the frequency of required of the AC generated.
Please enjoy, and I will try to answer your questions.
