Engine study & simulation at E-Props design office

The E-Props design office has recently acquired (*) several direct-drive engines to further its research and simulation work. The following models are now part of the study program :

• Continental O-200
• Lycoming O-235
• Lycoming O-320
• Lycoming O-360
• Lycoming O-540
• Volkswagen 1835
• Jabiru 2200 (4 cylinders)
• Jabiru 3300 (6 cylinders)

The digital modeling of these engines has enabled our LUKY software to carry out a complete dynamic simulation of the entire engine–propeller system.

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.

Just like in reality, it is the computed thermodynamic cycle — through the pressure exerted on the pistons — that drives the engine rotation.

This approach makes it possible to identify and characterize the vibratory behavior of the engine–propeller assembly even before the propeller is manufactured.
Thanks to this modeling, the evolutionary algorithm can reduce vibratory phenomena right from the design phase of the propeller.

The oscillations of engine torque represent the main source of stress for propellers mounted on direct-drive engines.
Their simulation and mitigation from the very start of the project help to extend the propeller’s service life.

In most cases, this method allows stress levels to remain below the material’s fatigue limit, thereby preventing any loss of potential due to fatigue.

Before a propeller ever turns for the first time on a real engine, it has already “flown” hundreds of hours inside our computers.
Through the digital modeling of engines and complete dynamic simulation of the engine–propeller system, E-Props anticipates and optimizes vibratory behavior long before production even begins.

By combining simulation, algorithmic intelligence, and mechanical expertise, E-Props continues to push the boundaries of light propulsion.
Every innovation developed in our design office stems from a strong belief: true performance is born from mastering the smallest details — even the invisible vibrations of a spinning engine.

(*) Some engines have been purchased, others loaned, and a few even generously donated — gestures that truly warm our hearts.
Each contribution, big or small, helps drive our research forward and keeps our passion for innovation alive.
A huge thank you to everyone who’s part of this exciting human and technological adventure !
