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



E-PROPS IN-FLIGHT VARIABLE PITCH PROPELLER GLORIEUSE
Extreme cold tests :-)
Very special blades, isn't it ?



Thank you for your interest in our range of in-flight variable pitch propellers GLORIEUSE for ROTAX 4-strike engines, currently in tests.
We are working hard to propose high quality, innovative, ultra-light and very reliable propellers.

At E-PROPS, each model is tested during some years before introduction to the market.
The GLORIEUSE range will be launched when all the tests have been validated.
We understand - and share - your impatience, but at E-PROPS, quality and reliability are coming before any other consideration.

Some pictures of takeoffs of the SKYRANGER 100 hp E-PROPS equipped with the prototype of inflight variable pitch propeller, called GLORIEUSE.
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 30 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, from 200 to 350 km/h.


=> Currently (February 2021), we carry out different flight test campaigns, and for that, the company E-PROPS hired a test pilot, Samy.

We're in the process of industrializing the Variable Pitch Propellers propduction line.
We manufacture the parts in the final moulds, and then we're going to put the propellers through a whole serie of mechanical tests.
This VP propellers concept is particularly innovative and required a great deal of development time and upstream testing.
Naturally, the health situation of this year delays us a little...
Now we're almost there. A little more patience and the first models will come out of our workshops in Sisteron !

TECHNICAL DATA

GLORIEUSE : 3-blade In-Flight Variable Pitch Propellers
For ROTAX 912S / 912iS / 914 / 915iS engines

Max power : 140 hp
Max RPM : 2.600
Moment of inertia : 2.400 kg.cm²
Regulator : FLYBOX or E-PROPS system
Regulation time from min to max pitch in less than 5 seconds
Safety stops min pitch / max pitch
Pitch variation : max range 27°
Weight (complete propeller) = less than 3,8 kg

The first version of GLORIEUSE is electro-hydraulic, with a Flybox-style dashboard display.
Thereafter, the mechanical part will be compatible with all actuator solutions.
A mechanical system (for engines with hollow gearboxes) will be considered later on.


Full carbon and advanced composites systems
Innovative patented blades profiles
Available in 6 diameters : 1,55 m / 1,60 m / 1,65 m / 1,70 m / 1,75 m / 1,80 m
3 blades' molds = blades geometry exactly adapted to the diameter of the propeller
Mounting flange : 6M8d101,6 mm bold diameter
Easy to assemble
Blade's replacement without disassembling of the hub
Special spinners : 13 diameters available
Unlimited potential
MTBO / Recommended major periodic inspection : target 2.000 hrs
This propeller is designed and manufactured for gear drive engines ONLY (do not use it on direct drive engines)


Price : for the moment, E-PROPS does not give prices.
Pre-order : to keep control its launch planning, E-PROPS does not take pre-orders.
