Design Benefits
- Rotary technology, compactness, extremely few moving parts: high reliability and longevity (3000-hour TBO), extremely low vulnerability to catastrophic failures, excellent operational readiness, unchallenged power density for a non-turbine engine (excellent power-to-weight ratio, optimal cowling aerodynamics), considerably reduced maintenance and overhaul costs, turbine-like smoothness resulting in higher comfort and lower cabin noise.
Rotating simplicity vs reciprocating complexity
- Can be mounted on standard dynafocal and or bed-type mounts, in both tractor and pusher configurations, work with commonly available propellers: very adaptable, easy to retrofit
- Works on most grades of gasoline whether leaded or unleaded, avgas or mogas, mixtures thereof, and can readily accept ethanol-blended fuels: unprecedented flexibility in fuelling options, reduced average fuel bill
- Liquid-cooling: faster warm-ups, elimination of thermal shock problems, high reliability, longer engine life
- Planetary reduction gear for low propeller speed on take-off (2,200 - 2,300 rpm) as well as in cruise (2,000 rpm and below): higher propulsion efficiency, propeller noise reduced by 10 db or more, meet current and future noise standards that very few current engines can meet
- Digital Engine Management (DEM) system with the latest technological innovations: dual ignition and dual injection, single-lever control for significantly decreased pilot's workload, easy, dependable starts, optimised engine settings and fuel consumption in all flight phases, reduced operating and maintenance costs, increased overall operational safety
RIGOROUS technological analysis and testing
- 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.
MISTRAL's laboratory in Geneva (CH)
- 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.
- The engines are thoroughly bench-tested in MISTRAL's laboratory, and flight-tested on the company's Piper Arrow III test-bed aircraft.
