One combustion engine powers one generator, with small buffer battery, producing electricity for one or more electric propulsion motors

• Combines advantages of conventional and pure electric propulsion systems
• Takeoff power comes from battery, so that combustion engine can be dimensioned for cruising power, only
• Engine-generator unit can be placed at most suitable position / center of gravity inside plane and be operated at best-point
• Electric motors and propellers can be placed in most suitable positions and their speed controlled without relation to engine speed

Battery-powered, pure electric propulsion systems: Batteries power one or more electric propulsion motors

• Environmentally friendly
• Allows for most efficient propeller speed and location
• BUT: Batteries are too heavy, so that flying ranges are only very short

HAT is subsidiary of Wankel SuperTec GmbH, producer of modern rotary engines

WST rotary engines can run on conventional and sustainable fuels:

• Diesel
• Jet A1
• Kerosen
• Hydrogen
• E-Fuels
• Bio-Fuels

High rotating speed at best point allows for direct coupling with highly efficient & lightweight generators

Using diesel fuel, HAT Hybrid Propulsion Systems are the perfect choice for military applications.

Using green fuels like hydrogen, e-fuels or bio-fuels, HAT Hybrid Propulsion Systems are the perfect choice for sustainable aviation.
