E-PROPS ASCALON : CARBON-TITANIUM PROPELLERS for DIRECT DRIVE ENGINES

E-PROPS is working hard on a wide range of propellers for direct drive engines (without gearbox) from 80 to 300hp.
It's the range ASCALON.
These propellers are made in VHR [Very High Resistance] Carbon with Titanium leading edge protection.
The first models are Ground Adjustable pitch. Later ranges of in-flight variable pitch (CS) propellers will be also offered.
Ultra-light, very strong, with innovative blade profiles and offering exceptionally high performance and TBO.


Update 19th of APRIL 2025 :
- Lycoming O-360 180hp => the first parts came off the molds. This propeller is currently being installed on our aircraft (Bilouis).
See news on our BLOG :
    ✗ E-Props 2-blade for Lycoming O-360 180 hp : work in progress
    ✗ E-Props Ascalon for direct drive engines : multi-objective optimization including noise reduction
- Continental O-200 100hp => this will be the second propeller model to be developed. Our friends of the SpeedJojo are ready for testing :-)
- Other Lycoming / Continental engines between 100 and 300hp: coming soon.

Propellers for Jabiru 2.2 and 3.3, Volkswagen, UL Power, Limbach, Sauer, D-Motor... to follow, also as soon as possible
Our aim is to thoroughly test all models, in-house and/or with partners, and then to market numerous propeller models for, eventually, all direct-drive engines.
Work on EASA CS-P & FAA 14 CFR PART 35 certification of these models and tests to obtain numerous STCs are being carried out in parallel.



We understand - and share - your impatience.
Releasing a new range that is much more efficient than what is currently on the market inevitably takes time.
To reach this target, we have developed a new software : LUKY SOFTWARE.
This software is a model of the type lifting line for the speed of execution, in order to allow the exploration of the domain of possible propellers with the help of an evolutionary algorithm (metaheuristic), in order to automate the search for propeller solutions (mechanical and aerodynamic dimensioning) for a given problem.
Thousands of hours of code by highly specialized engineers were required. This software represents an exceptional step forward in the development of equally exceptional propellers.
17 years' experience in carbon propellers means we can always go further...

You can be sure that we are doing our best to industrialize, test then market this range as soon as possible.
As new propeller models become available, we will detail them on this site.

=> PS: no release date or price yet - please be patient, it's coming soon...
