CoAxe Aircraft Engine

 

The CoAxe Engine is an Internationally patented design (US Patent No.: 8,863,643 B2) with specific advantages:

  • Perfect balance by design (including drive torque moments)
  • Up to 16% increase in propulsive efficiency (contra-rotating props)
  • Multiple fuels including Jet A (leaded AVGAS being phased out)
  • Ultra low vibration (all opposing forces equal and opposite)
  • Reduced weight, increased payload (no transmission for coaxial drive necessary)
  • Competitive pricing (reduced moving parts, cost-effective manufacture)
  • Improved fuel economy (opposed piston Diesels historically highly efficient)
  • Greatly reduced fire hazard (exhaust manifold 350 degrees C cooler)
  • No electromagnetic interference (single throttle Diesel operation)
  • Low noise level (a result of opposed piston porting)
A new approach to aviation, marine, submarine propulsion and power generation:

"The concept of a coaxial engine is intriguing as well as elusive to some of the most respected engine designers in history; seeing you overcome the pitfalls that eluded others before you is truly an inspiration and bodes well for the future of cost effective, high performance propulsion systems."
