EASA certification of Rotax 915 (Now 141 HP)

from what I have read its got a new crankcase, gearbox, crank, pistons connecting rods and heads as well as a new ECU and turbo as well as a new intercooler and a few other tweaks. hence the two years to recertify the engine

Keeping many of the original engine's dimensions. IF one started from scratch THAT would be most unlikely, and it would also be unlikely they would include a pressed up crank. This may have been altered but it would make the crankcase more bulky. Compromise results from this attempt at economy.. AS I said "We will see". Nev

the certification process is holding manufacturers and innovation back, where are the direct injection gasoline engines in aviation?

 

 

[facthunter]

Only the most "modern" vehicles have them. I wouldn't like to put stale fuel through them. either. They can't detonate , but it's exotic technology. Nev

Let us use turbines...the only issue is the fuel usage..but power for size and weight performance is streets ahead and as Nev has said the reliability is multiple times better

 

A small PT6 would be awesome
