I think that you can look at the market to see where the crossover
occurs. THere are currently no production piston aircraft engines over 450hp and there are no aircraft turbines under 400hp. There's lots of ground turbines under 400hp so we know there's a market there; [...] A ground turbine runs at almost constant speed, near its design point, so even at small dimension can still be fuel efficient. Part load fuel consumption of a gas turbine is a bit too high, particularly for GA aircraft (considering their flight pprofile). -- Fritz |

AFAIK, they say just the opposite (to me, at least): The Lyc version would be for the US market. It's also a matter of using the DA42 in a training environment, where pilots still need to be trained for three levers, not the single one the Thielert has. In a sane world the rule would be "single pilot IFR=single lever power control". |
