GEnx-1B engine for B787 Dreamliner

Dale Carlson, Executive for Advanced Engine Systems at GE Aviation is our guest. Dale is responsible for all government funded technology initiatives, and also for aligning technology as it matures with future propulsion system offerings for GE Aviation.

We talk about why this is an exciting time to be in the commercial engine and airframe business. What’s left in Brayton cycle engines (not much) and what we can do about that. Why pulse detonation is not a good solution. Dale talks about adaptive (or variable) cycle engines, the fuel burn improvements needed for new engine offerings, and why we’ll see integrated airframe and propulsion systems in the future, the blended wing aircraft being an example.

Distributed propulsion with large numbers of engines on the aircraft is a future possibility, as is all-electric propulsion. Of course, we can’t talk about fan diameter without covering thermal efficiency and propulsion efficiency. We talk a little about the future of the F136. That’s the engine GE is developing as an alternative to the Pratt & Whitney F135 that powers the F-35 Joint Strike Fighter. Finally, Dale offers some sound advice for people considering a career in aerospace.

The week’s aviation news:

David provides another powerful history lesson in his This Week in Aviation segment.

In this week’s Australia Desk Report: Qantas politics goes on and on and on….. RAAF takes delivery of the last four Super Hornets, Omega Tanker takes three ex RAAF 707 tankers, Department of Defence looks seriously at C27J Spartan to replace Caribous, RAAF looks at a disposal date for C130H.

  1. Here’s a photo of the Avro Vulcan’s main landing gear – yup, 8 wheels each leg so 16 wheels on the main gear http://www.flickr.com/photos/peteredin/2717115667/

  2. Loved – loved –loved Dr. Dale Carlson’s interview. He was very insightful and you guys had some great questions. As Dr. Dale pointed out, energy density is still a BIG problem for anything not fossil fuel powered. Unless we go back to the blended wing nuke powered concept. It would need to a flying boat – of course.

  3. [...] In other news, I’m now doing freelance work for Aviation International News, so please go over and check out what I’m doing.  Again, I’m still trying to catch up on my Airplane Geek podcast episodes, and I really enjoyed Episode 170 – GE Aviation Looks to the Future. [...]
