- Research and testing platforms
Advantages
Your advantages with our electric aircraft propulsion:
- High efficiency across the entire speed range
- Robust, low-maintenance, easy to integrate
- No emissions, no flammable liquids, no exhaust or cooling systems
- Smooth running & low vibration – increases comfort and protects the structure and the environment
- Full torque at all times – regardless of altitude, temperature, and air density
- Self-generated power – e.g., through regenerative propeller operation
Scalable solutions from 10 kW to 500 kW
Why choose this product?
Propeller drives offer high energy efficiency and score points for their efficiency. This contributes to longer ranges.
They generate significant thrust, especially at typical eVTOL flight speeds.
Because propeller drives have few moving parts and no complex gearboxes, they are also particularly reliable. emission-free energy sources such as hydrogen or green electricity, our systems make a decisive contribution to climate-neutral aviation.
