Safety, Sustainability and Efficiency

Proprietary electro-propulsive technology optimised for clean performance.


Reduced stall risk and Short Take-Off and Landing (STOL) distances by optimising the use each propeller’s slipstream.

Clean and Quiet

Producing electricity from fuel cells powered by hydrogen allows for a uniquely quiet flight experience, with pure water being the only by-product.

Robust to Failure

Spreading the power generation across independent propellers ensures that no single breakdown is able to cause an aircraft level failure.

Increased Range and Endurance

BSA's hydrogen system contains more energy per unit mass than a battery-powered alternative, allowing for longer flights.

Fast Hydrogen Refuelling Time

With a single refuelling port per wing, the total turnaround time is less than 10 minutes.

Modular Electro-Propulsive Units [PATENT PENDING]

The powertrain is fully integrated into a set self-contained pods, each one being modular and easily dismountable.

Reduced Maintenance Costs [PATENT PENDING]

Independent, interchangeable and lightweight propulsive modules that can be dismantled and replaced in minutes.

Comfortable Cabin Design

Ergonomic and spacious, with extensive outside visibility.
