Engines

Simplicity, carried to its extreme, becomes elegance.

On the average mission, a jet-fueled DeltaHawk engine is up to 40% more efficient than an Avgas engine—improving range, increasing available payload and lowering cost of ownership. Multiple redundancies increase safety. And operating with widely available jet fuel, you can fly anywhere in the world without the worry of finding places to top off. But we didn’t stop there. Our engine’s small, aerodynamic profile allows an elegant cowl design with less drag, further increasing fuel efficiency. To do that, we literally turned the engine upside down. And ended up doing the same to an industry.

Future

A better aviation engine. But first, simply a better engine.

We set out to reinvent the standard in piston-aircraft power. What we ended up with was an engine with an extraordinary number of other uses. It’s lightweight, compact and highly reliable. Can you imagine a project that puts those attributes to good use?
