SMA develops and manufactures piston engines burning Jet fuels, purposely-designed for the general aviation market, for single and multi-engine aircraft.

SMA is currently making production of the SR305-230E, its 4-cylinder engine of 230 hp. A new 6-cylinder engine is under development with power over 300 hp.

SMA engines technology emphasizes reliability and robustness, with the same ease of operation as with turboprop models.

SR305-230E®

The current 230 hp version SR305-230E designed for the general aviation market, specifically for jet fuels aircraft, has been certified by EASA and FAA in 2011 The SR305-230E is intended for OEM's integration programs. It is designed for single or multi-engine application, and for professional as well as private use.

The SR305-230E offers the following advantages: use of jet fuels available around the world, fuel cost savings by over 30% compared to Avgas engines, optimized aircraft operation, and no lead exhaust.

  • Four cylinders
  • Certified ceiling : 20,000 ft
  • Critical altitude : 10,000 ft
  • Constant speed of propeller : 2,200 rpm

The SR305-230E has been selected by Cessna for the Turbo Skylane JT-A, as well as by Odessa aircraft plant (Ukraine) for the DELFIN aircraft.

In order to meet market needs, SMA is currently studying more powerful version of the current engine.
