Pratt Whitney PT6A Turboprop Turbine Animation

Good question. This question would be better for PT6Nation to answer. They are the "gurus"!. Send them the questions here and I am sure that they will reply to your question. Alternatively, you can pop over to their website. Other PT6A gurus, please post answers, when possible. Sorry that I cannot post the link here due to usage terms, as per youtube. Thanks!

What keeps the exaust from coming back into the intake causing a compressor stall?

Now I know why the turbine exhaust ports are just aft of the prop. Thanks!

We've seen a lot of cool turboprop animations in our day, but this is by far the coolest! Nicely done, you're very talented. Have you heard of PT6 Nation? There's no doubt our community of PT6 enthusiasts would LOVE it if you share your videos on our site.

@pt6nation Thanks for the comments! It will be very cool and an honour to have our videos shared on your site. Drop me a name here and I will contact you to discuss further. Mike

So the pt6a is a centrifugal turbine not an axial?

[1746980j]

@tranceaddict704 : A small "lifting" from pt6nation. Please proceed to their webiste for more information.

PT6 engine technology:

Multi-stage axial and single-stage centrifugal compressor Reverse flow, radial inlet with screen for foreign object damage protection Large high-power PT6A engine models incorporate 4-stage axial and 1-stage centrifugal Small and Medium PT6A engine models incorporate 3-stage axial and 1-stage centrifugal

Thanks for viewing!

@1746980j You are totally right.

@tranceaddict704 PT6Nation's website is your "go to" ressource for learning and sharing stories about the PT6 engine. Join the Nation and share yours! : )

Thanks for posting this useful training device. I like the airflow demonstration and the speeds of the different turbines. I've bookmarked this one... PT6 driver.
