DeltaHawk Engine Benefits
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.
DeltaHawk’s extraordinary engine combines proven technologies with new innovations and modern materials. The engine’s base technology is Compression Ignition (also known as Diesel) that is known for durability, high efficiency, and incredible torque.
