They stopped making the Dash8-Q400 which uses the reliable Pratt 5000hp PW150. I’m not sure who would want something 6700shp. Maybe military?
ATR 72s use 2750shp engines which would use much less fuel.

de Havilland Canada (Viking Air who bought the brand, designs and certificates) are restarting production of the Dash8, the Canadair 515 (firefighting) and the Twin Otter.
But there's a comment that says all the planned applications are for military transport and related (firefighting, patrol, AEW&C) aircraft.

I thought I read something about production of the dash 8 starting again soon

Q500 with 150 seats

What's the application for these things?

It's interesting how all of those bar the amphibious/firefighting AG600 are based on (developments and stretches of) the An-12 and An-24. It shows how good those designs were, especially for their time, if they're still useful as the base (I think it's fair to assume that China has the capacity to design all new planes, and it does, even if they have some inspiration here and there).

Could give the SR-71 a run for its money.

It's a little more powerful than an Allison T56 (the engine which powers the C-130 Hercules), so I'm guessing something pretty hefty.

That’s the engine that’s in a Saab 2000 this is gonna be one fast turboprop
ninvti@reddit
Why are big turboprops ever chosen over jets? (😁)
Rusher_vii@reddit
I believe its for reliability and low speed thrust.
Reliability because debris can't be sucked into the turbine.
Secondly I believe theyre lighter and come with better low speed thrust so shorter take off distance which would be more important to military applications.
Someone more educated than me pls chime in if I've got it wrong.

All that and better gas mileage

Will this fit in my Miata?
dotancohen@reddit
Your Miata will fit on it.

They might be closing the gap in terms of competition but challenges will remain well through 2028 especially with expected tariffs and intellectual property limitations. Domestic approval within the PRC can be expedited especially through vertical integration with state-owned manufacturers in the aviation industry, but don't expect to see this thing FAA/EASA-certified until at least 2030.

Also just having an engine is one thing. Having it be powerful, reliable, easy to maintain, and efficient - those are whole another topics. I guess the power is there, but as for the others? We shall see.

Why does it take so long to certify?
A3bilbaNEO@reddit
Asking the real question. The first 777 variant was flying passengers the year after it's first flight.
Amadeus_1978@reddit
I’m sorry r/aviation but why are you excited about something five years away? Are you preordering?
chroniclad@reddit (OP)
Civilian certification for foreign use is different than military certification. They might be operational on Chinese military aircraft before 2028.
