Czech Evektor EV-55.....a Chieftain replacement???
Czech Evektor EV-55.....a Chieftain replacement???
Just found out about an interesting 10 seat aircraft that nay be built in Canada, 10 seats, high wing, podded landing gear, much like a small ATR. Powered by 2 x 550 PT6 turbo props. Anyone seen anything of this aircraft. Could this be the much awaited Chieftain replacement/mini airliner.
Dubious about the powerplant tho, surely a 500 hp version of Centurions V8 diesel would be a goer.

- Powerful airplane - reliable and well-proven turboprop engine \
- Fast airplane - max. level speed over 220 kts
- Environment-friendly aircraft - minimal impact on environment
I am yet to see any twin turbine aircraft make economic sense in general charter and low capacity RPT with less than 16 - 18 seats.
Payload over 800 nm is less than a C208 Caravan. At max fuel the aircraft appears to have a payload of only 200 to 300 kg???
Fitting V8 engines may appear to make economic sense but their added weight (over PT6A-21s, approx 140 kg each) would further reduce payload. (Why choose -21s over the superior -112/-114 engine or lower cost Walter 601 turbines???)
Stretched to 18 - 20 seats with PT6A-34 or -42 engines, the aircraft may start to make economic sense, although I am not sure it would compete with similar size pressurised aircraft.
It is a concept aircraft only, which may never see the light of day.

AS from memory the Noranda V8s they played with about 10 years ago put out as much power as the Pt6 with reduced fuel consumption and the setup carried less fuel then the standard aircraft they had them fitted to a C90 King Air.
Sir Pratt. Walter claim "TBO options of ..... 3000 hour/6600 cycles depending on the ordered configuration" and no HSI?
But the big difference is cost. An operator can do a heap of engine changes for the difference in cost between a -21 HSIs plus overhaul and a new exchange Walter engine.
But you're correct - in their class, nothing beats a PT6 - or JT15, or PW100 - but then, I'm biased!
I can't see the economics in this concept aircraft. Two thirds of a Bandeirante with negligible long range payload, for many times the capital cost and probably similar operating costs. The western world has moved on beyond this class of aircraft.
bushy. What makes you think CASA are pro C208?

Always thought this was the niche that GAF was aiming at with the N24 Nomad. It would have been interesting to see what the gonad would have turned into if they ditched the helicopter engines and fitted PT6s and moded the the tail to a T-tail configuration.
Twotters are back in production as well.

It may replace the piston twins around but 1.5 mil its steep plus as the mines start to move onto bigger things i think its to late if it was tryed maybe 15 yrs ago it may have had a chance.
