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.

FAA is US and EASA is EU...China no need this certification to sell to other countries. Even ARJ21 not certified by EASA or FAA but is flying from Indonesia and Malaysia. As long as China , Infobesia and Malaysia Flying Authorithies Validated and Approved it. The jets can fly in the countries respective airspace. The whole world knew it is a monopoly game.

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.

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've heard about the Dash8 relaunch from Vik8ng for years now, does it really materialise? Also heard they're looking into building a shorter version to replace the 100/Q200/Q300?

sofixa11@reddit

They're currently moving factories, so I'd guess soon but not yet

qonkk@reddit

Hopefull, I love the "bomber" and we need a counterweight to ATR!

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

They're thinking of souping up their Cessna 208B's, if I'm not mistaken. 🤙

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.

They are more fuel efficient for shorter routes where a greater proportion of the mission is lower speed (short cruise time). Props have a better propulsive efficiency at low speed where pushing a larger volume of air at a lower speed is most efficient.

Don't they burn less fuel too?

Similar-Good261@reddit

Much cheaper (sry: more economical) to operate on short routes.

All that and better gas mileage

Dananddog@reddit

Perfect, now I just need to find a used lancair 4p kit to swap this into and I'll be set.

What's the application for these things?

[-]

chroniclad@reddit (OP)

Civilian application:

Replacing foreign engines on MA700 airliner.
Powering AG600 amphibious plane

Military Application:

Powering KJ-600 AWACS
Replacing old engines on KJ-500 AWACS
Replacing old engines on Y-9 series of transport and auxiliary planes or powering its successor, Y-30.

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).

Civilian certification for foreign use is different than military certification. They might be operational on Chinese military aircraft before 2028.
