E-PROPS GLORIEUSE : Range of In-Flight Variable Pitch Propellers for ROTAX serie 9xx



E-PROPS IN-FLIGHT VARIABLE PITCH PROPELLER GLORIEUSE
GLORIEUSE - June 2021


Here is the range of in-flight variable pitch propellers GLORIEUSE for ROTAX 4-stroke 912S and 912iS engines, currently at the end of the test campaign.
We are working hard to propose high quality, innovative, ultra-light and reliable propellers.

At E-PROPS, each model is tested during some years before introduction to the market.
The GLORIEUSE range will be previewed at the Blois Airshow 2021 (Sept 3, 4 and 5, 2021 in France, GC 32 Booth East Zone). Then it will be offered on the market from September 2021.


=> Currently (July 2021), our test pilot Samy finished the last flight test campaigns.

Tests in progress : Samy Dupland (test pilot) and Jérémie Buiatti (designer)

We're in the process of industrializing the Variable Pitch Propellers production line.
We manufacture the parts in the final moulds. The last mechanical tests were carried out on the flight parts; they will be presented in several videos.
This variable pitch propellers concept is particularly innovative and required a great deal of development time and upstream testing.

Of course, a variable pitch propeller is not very interesting on a SKYRANGER.
However, the SKYRANGER is a good machine for testing over a speed range from 60 to 190 km/h. This one is the "prototype aircraft" of E-PROPS, which we equip with many recording systems : the DAU MERLIN between the propeller and the engine communicating via Wifi with the computer for data recording, a cockpit equipped with many instruments and cameras, a boom under a wing for speed and incidence measurements, etc.
A very important part of the development of the propellers is carried out with our SKYRANGER 100 hp, flown by Samy Dupland, E-PROPS test pilot.
Once validated on this first speed range, our propellers are tested on other faster airplanes : VL3, BLACKWING, WT9 Dynamic, SHARK, FK12...
