Glorieuse on Alpha Trainer 912

This week, the Pipistrel Alpha Trainer with Rotax 912 80 hp has been equipped with a Constant Speed propeller Glorieuse. A great success ! 😀

Here are the first test results and comparative with the standard propeller from Pipistrel.

By installing a Glorieuse propeller, Alpha Trainer pilots gain 50 m at rolling, 250 ft/min of rate-of-climb and over 20 kt / 35 km/h cruising speed at 5000 rpm !
And the Glorieuse propeller with spinner weighs 0.9 lb / 400 g less.

The pilot’s comments after the test campaign:
“This propeller is simply incredible !
At 5100 rpm, cruising speed is 115 kt / 213 km/h (MAP 25).
The engine is much quieter, with much less vibration, so the lexan doors don’t shake at all.
Excellent, the Alpha Trainer with Glorieuse is now another plane.”
