What’s Going On?

  • DeltaHawk is engineering clean-sheet, 160 hp, 180 hp, and 200 hp highly-innovative aircraft engines
  • Lightweight (engine dry weight: ~315 lbs.)
  • 4 Cylinder, 2-stroke, piston-ported Compression Ignition (CI) engine
  • Fuel: Jet-A, Jet A-1, JP-8, JP-5 or diesel fuel
  • Initial flight-test data indicates engine is already 35-40% more fuel-efficient than traditional Gasoline engines
  • Currently upgrading processes and technologies to further refine engine, including performance and endurance enhancements


Program Progress:


Over the last two years, DeltaHawk hired 24 talented engineers, technicians and other professionals.

FAA Testing and Certification:

Current testing and certification readiness activities:

  • Technical upgrades – design, performance and process
  • Qualification and endurance testing
  • Going above and beyond certification requirements


  • New state-of-the-art dynamometer testing facility, with both water-brake and propeller dynamometers
  • Extensive investment in data acquisition and analysis systems
  • New high-tech modern offices and labs
  • New state-of-the-art Quality Labs, including Coordinate Measuring Machines (CMM), Optical Comparator, and other required metrology equipment



Secured adequate funding for engine design, certification and production, but has an open investment round for Accredited Investors.

Engine Availability:

Production of certified engines planned for summer 2019.


Please contact DeltaHawk Sales for pricing inquiries.

Aircraft Compatibility:

DeltaHawk engines are compatable with most general aircraft including Cessna, Piper Archer, Warrior, Seneca, Cirrus, Diamond DA-42 Twin Star and Velocity single- and twin engine models.

  • Presently has an open FAA Supplemental Type Certificate (STC) project for an engine installation in a Cessna 172.
  • Planning initial STCs for other aircraft, including Piper Archer/Warrior/Seneca, Cirrus, and Diamond DA-42 Twin Star aircraft with other aircraft to follow.
  • Has active projects underway for Velocity Single and Twin engine aircraft.

Higher Power Engines:

A complete engine line with up to 400 HP engine series is planned.
