Research & Development

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-I, JP, 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

Program Progress – Staffing

Over the past year, DeltaHawk hired nearly 20 talented engineers, technicians and other professionals.

Program Progress – FAA Testing and Certification

Current testing and certification readiness activities:

  • Technical upgrades – design, performance and process
  • Qualification and endurance testing

Program Progress – Infrastructure

  • 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.


Secured for finalizing engine upgrades, FAA Certification and production.

FAA Certification Status

Well underway for FAA Certification and anticipate certification completion by AirVenture 2017.

Engine Availability

Production of certified engines planned for summer 2017.


Price announcements expected near mid 2017 as engine is optimized and costs reduced.

Aircraft Compatibility

  • Presently has an open FAA 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.

V8 Program

V8 engine development to follow V4 program, with expected completion in early 2019.
