Coaxial power without the weight of an expensive, complex and 'prone to failure' planetary gearset. The first practical coaxial internal combustion piston engine.

The CoAxe Engine is a vibration free design with specific advantages:

· 6 - 16% increase in propulsive efficiency
· Lighter, produces more power and torque
· Direct-drive coaxial power at required RPM
· World-first inherent gyroscopic torque cancellation
· Improved fuel economy, multi-fuel application
· Reduced emissions, increased payload

Applications include coaxial helicopters, ships and boats, aircraft, submarines, torpedoes, pumps, generators, unmanned and remotely piloted aerial, submersible and surface vessels, hovercraft.

"The CoAxe engine is an innovative design with novel features that in a mature design could offer significant advantages in particular applications, with helicopters the first obvious application. As with all new engine developments it will require significant design and development effort to finalise a production design but AADI can see no fundamental problems that would prevent such an engine demonstrating its unique and valuable features."
