Testing a Starfighter Engine
Our GE J79-19 turbojet, out of an Italian air force Starfighter, being put through its paces, and burning several hundred gallons of sweet Jet-A in the process. My rear-engine camera was blown down the field, rescued and put on intake monitoring duty. It still couldn't keep still. I held my main camera, standing as close as I dared to the afterburner nozzle, and my knees actually buckled a bit every time it lit off. This engine makes some smoke because it has standard combustors (see my combustor videos), and passed the test with ease. It ran like a Swiss watch, er... like an Italian turbojet !
Sabre Jet Engine: first start
The first start and initial test run of the Orenda type 14 turbojet that we have been working on for almost a year now... you and me! It's been a lot of work, and now it's all on the line as we crank this baby up, hit the sparks and spray those combustors with Jet A. It was an exciting and Exhausting day... A special note: this is not a hot start, but fairly typical of the older generations of turbojets to have flames shoot out the tailpipe on startup. The video response is from Burning Man participant Kunal Dovedy, and the engine section he used is the exact one featured in my video "dropped into a turbine engine".
Compressors - Turbine Engines: A Closer Look
Lets look around inside the compressors of a few different turbine engines. How does it all fit together, where does the air go, and how does it work ?
