Pratt & Whitney Canada PW500 Turbofan Jet Engine: An Overview at NBAA BACE Las Vegas

Thank you for sharing this Aviation Industry company.

Nice video. I was gonna comment on the counter rotation because there is a display video from 10 years ago where they actually counter rotated so it's curious why they've made this stand different. I would have asked about the color of the blades, they all appear to be the same material but I assume the hot section is inconel and the others are not. Maybe it's a surface coating somehow.

[@PersonalWings]

Dan there is actually a switch on the engine display and we could have rotated it in both directions for demonstration purposes.

[@MrTp057]

What's the story on the PW300 listed on the sign? Is that an even smaller version? And what about cost? Have they been developed to reduce cost? What about expectations for use cases? Thrust discussion, fuel burn...

[@PersonalWings]

Not a clue, reach out to P&W

[@DanFrederiksen]

there is no sense to the PW naming. The 600 series is the smallest, all the others are bigger, both 300, 500 and 800. There is no sense to the pricing either. Their smallest engine 610 is a million dollars, 5 times bigger is also a million dollars. They like that number. The more complex larger turboprop PT6, also a million. The actual PW610F engine might cost 10k$ to make. Am I calling them greedy? yes I am.

For newbies, the performance figures the ultralight category companies are citing for their VTOL fliers are >mostly< in compliance with the 'ultra-light' aircraft category, not by design. 👑🤜🇺🇸🤛👑 We are designing 2 point-to-point personal air mobility VTOL systems, the PersonalJet, one for personal ownership [striving for

The center high compressor section is spinning backwards the wrong way, but the fan is spinning in the right direction, what’s the deal. I don’t think the rep even knows what he’s looking at.

[@PersonalWings]

Yeah, he noted it as you saw. He was very knowledgeable on and off camera.

6:00

[@tropicthndr]

Ok I’ll cut him some slack since he eventually points out the stupid rotation in the display at 6:10.

So much wasted space for additional axial compression stages with shorter chords and higher efficiency. Listening to most pilots explain engine physics/dynamics is always a good time 😂

[@PersonalWings]

I'm not a power plant engineer, however in talking with Rob (the engineer with us in the video), PWC probably has optimized the configuration for this particular engine. They have others with various stages and designs, which may have additional axial compressors. It was nice to have Rob join us to correct any misstatements, since he was one of the designers. I've flown a number of aircraft with engines designed by him and they are rock-solid .

[@DanFrederiksen]

there is a manufacture and service consideration no doubt but what I've noticed is that their smallest PW610f has only 5 elements total, 1 axial compressor and 1 centrifugal and it appears to manage proportional fuel efficiency. The Eclipse jet with PW610f uses much less fuel than say Phenom 100 which uses Williams FJ33 that has 3 axial and 1 centrifugal. About half thrust, half weight of plane, half fuel burn and same speed. So either smaller engines are more fuel efficient or it doesn't take many stages to get decent efficiency. That PW charges 1 million dollars for their tiny engine means the savings of simplicity is passed onto their greed.

@@DanFrederiksen We fly jets with all the engines you mention. Thrust has a direct relationship to fuel burned. The Eclipse PW610F is a very efficient engine, but is also powering a jet with a MTOW of 6000 lbs, while the P100, Mustang, etc are much larger jets. The Eclipse also is more efficient on comparable trip due to its size and design. The P100 and Eclipse have almost the same block-to-block speed, while a bit faster than the Mustang. We also fly all the Citation 525 series.

[@bradarsenault6984]

​​​@@DanFrederiksen comparing efficiency between engines on different airframes by using fuel consumption, aircraft cruiser speed, weight, etc is extremely faulty. TSFC is really the most accurate way to compare turbofan engines. Smaller engines are generally less efficient than a similar but larger design.

[@DanFrederiksen]

@@bradarsenault6984 if you have the reliable values, sure. Do you?

[@nadahere]

We plan to develop advanced microturbines for our mobility systems in the civilian market based on my innovations.

[@PersonalWings]

Let us know how your project progresses.
