1 - E-Props LUKY software

Profiles optimization using Artificial Intelligence

LUKY software models the behavior of an E-Props propeller on a given engine, from an aerodynamic and mechanical point of view, including vibration analysis and service life calculation.
It enables the E-Props design office to develop blade profiles adapted to each aircraft - engine - application.

=> See description here: 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 and tests by highly specialized engineers were required to develop this software.
LUKY represents an exceptional step forward in the development of equally exceptional propellers.

2 - Propellers design / Tests / Theory / Moment of inertia

E-PROPS propellers are designed to offer the best possible performance, while being both ultra-light and extremely strong.

✗  The propeller optimization method is a complex iterative process.
=> See description here: E-PROPS PROPELLERS DESIGN

✗  Propeller testing is essential to validate calculations and models, and to compare performance with other propellers.
=> See description here: E-PROPS TESTS

✗  Propellers comparative tests in flight : a very interesting and complex exercise.
=> See method here: PROPELLERS COMPARATIVE TESTS IN FLIGHT

✗  To understand how a propeller works, it's essential to understand the laws of experimental physics.
=> See here: PROPULSION THEORY

✗  Moment of inertia [MOI] is a very important parameter for propellers.
=> See explanations here: PROPELLERS & MOMENT OF INERTIA
=> Rotax Service Instruction: Propeller mass moment of inertia for ROTAX

✗  Influence of propeller inertia
Jérémie Buiatti, designer of E-PROPS propellers, has taken a close interest in what happens between the engine and the propeller. He wrote an interesting article for the publications of the "Colloque de Cachan 2016" organized by the French association INTER ACTION (Association de Sauvetage Créatif du Savoir Aéronautique).
=> See this article here: "Les pistons tapent, le réducteur trépasse" (PDF in French)

✗  Propellers have come a long way since the early days of aviation. E-Props are 3rd-generation propellers.

3 - E-Props: Efficiency / Lightness / Noise reduction

✗  E-Props : exceptionally efficient propellers
E-Props propellers have very special profiles and specific designs to reduce blade drag, and thus achieve the best possible thrust.
=> See description here: E-PROPS EFFICIENCY

✗  E-Props : ultra-light propellers
E-Props are the world's lightest propellers.
To understand why these propellers are ultra-light, and why the lightness of this equipment is essential:
=> See explanations here: E-PROPS: ULTRA-LIGHT PROPELLERS

✗  E-Props : noise reduction
Since 2008, the E-Props team has been carrying out in-depth research into propeller noise and how to minimize it.
