Turbine Class

This past week was spent learning about turbine engines. In the past, the majority of mission aviation aircraft had piston engines. However, this has changed over the years as avgas, which fuels these engines, has become uncommon and expensive.

Dan is conducting a borescope inspection of the Power Turbine blades. A borescope is essentially what the CIA uses for spy operations which means we are pretty cool! Well not exactly, but it is cool to take a camera on a long wire to inspect the guts of an engine.

I love this picture. It is a wordless expression of the eagerness to work together in fulfilling God's calling.

The compressor turbine and blades alone costs up to $160,000 new. Proper training and careful maintenance is essential. 

During this past week I was amazed by the seemingly endless knowledge our instructor, Ron Hollis. He has been working on PT6 Turbine engines for longer than I have been alive and it was a privilege to  learn under him. Covington Aircraft has been generously loaning him to JAARS a few times a year for the past 5 years.
