Technology

MISTRAL engines have an unprecedented combination of advantages that allows them to meet current GA regulations, that very few current engines can meet. This makes them the engines of choice for 21st century General Aviation.

  • Uncompromised reliability, robustness and simplicity of the rotary technology: 90% less moving parts than reciprocating engines, thermal shock eliminated with liquid-cooling, full redundancy of FADEC system

  • Unmatched flexibility in fuelling options: multi-fuel, MISTRAL engines works on avgas, unleaded mogas, mixtures thereof as well as ethanol-blended fuel
  • Substantially decreased cost of ownership: 3000 hours target TBO, fuel consumption optimised in all flight phases, reduced average fuel bill
  • Reduced environmental impact: 10 db noise reduction inside and outside the cabin thanks to the PSRU; unleaded gasoline intake
  • Higher propulsion efficiency: the PSRU (Planetary reduction gear) allows low propeller speed on take-off (2,200 - 2,300 rpm) as well as in cruise (2,000 rpm and below)
  • Easy to retrofit: compact, parts easily accessible, mountable on dynafocal or bed-type mounts, tractor of pusher configurations
  • Optimised comfort, simplified operaitons: 10 db less noise, single-lever control, next-to-no vibrations, higher payload

MISTRAL's proprietary FADEC (Full Authority Digital Engine Control) system offers the latest in technological innovations:

  • dual ignition and dual injection
  • single-lever control (significantly decreased pilot's workload)
  • easy, dependable starts
  • optimised engine settings and fuel consumption in all flight phases

Rigorous technological analysis and testing

The test-bench in Geneva

The engines are thoroughly bench-tested in MISTRAL's laboratory, and flight-tested on the company's test-bed aircraft.

  • All critical components have been designed, calculated and tested using the latest industry Finite-Element Computing software to ensure that they stand up to the most rigorous loading conditions that extreme flight manoeuvers can produce.
  • Manufacturing methods as well as both destructive and non-destructive testing techniques are selected and implemented to ensure the conformity, safety and integrity of each part.
