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.
Certified ceiling : 20,000 ft
Critical altitude : 10,000 ft
Constant speed of propeller : 2,200 rpm
In order to meet market needs, SMA Aero Engine is currently studying more powerful version of the current engine.
A 260hp Variant is as well EASA-Certified and available for installations, called SR305-260E. This more powerful variant is based on the SR305-230E to assure commonalities and offers higher power.
TAILORED TO MARKET NEEDS
The SR305 is a compression ignition engine purpose-built for aircraft integration. It has four- horizontally opposed cylinders and is air and oil-cooled. It is fully compatible with a large variety of Jet fuels available worldwide. Specific version are developed to answer OEM’s performance requirement. Air-oil cooled (no additional fluid), Propeller directly driven w/out a gear box and full mechanical control capability.
ENHANCED PERFORMANCE
The SR305 engines offer higher performance than comparable turbocharged engines fueled by Avgas. The turbocharger, designed by Safran Aircraft Engines, maintains 260 hp up to 5,000 ft and 230 hp up to 10,000 ft and retains the engine’s performance independently of outside air temperature.
