News, facts, and comments on the coming revolution for piston-engine aircraft.In 1998, one diesel engine flew on a converted airplane for the first time since 1945. Today, close to 4,000 singles and twins are flying. This is the beginning of a worldwide trend which will eventually allow a rebirth of the piston-engined aircraft, around new specs and new missions. DieselAir Research, Inc., the publisher of The DieselAir Newsletter, offers strategic intelligence services to the aircraft industry, its suppliers and its customers who ambition to benefit from this global change of paradigm which will mean new markets, new concepts, new services, new materials and components… You may be interested in our services if your firm designs and/or manufactures aircraft and components, aero engines, avionics, propellers and engine components, fuel systems or additives, advanced materials, or industry specific machinery for manufacturing of these; or provides aviation services such as fuel production or distribution; flight training, aircraft chartering, maintenance and operations (FBO’s); or airport management and design, traffic control, hangar, materials handling and storage equipment; or consulting and financial services for these industries; or advertising, sales promotion, trade shows, specialized publications.

 French engine manufacturer SMA continues to pursue development of its aviation diesel engine SR 305-230. Alain Pierre Deniau, Senior Vice President of the SMA subsidiary in the USA recently stated at the AOPA Expo: ”Both the EU as well as the American legislator are continuously tightening exhaust regulations. This means the end of avgas sooner rather than later.” SMA is absolutely confident that its diesel engine - which runs on Jet-A fuel - will produce lower exhaust gas and noise emissions than current aviation powerplants of this class. The latest improvements of the SR 305-230 encompass twin exhaust gas driven turbochargers, a new intercooler, as well as improved cooling due to optimized engine ventilation. In addition the starter and the alternator were renewed and the cylinder heads were overhauled. SMA is continuing to diligently collect field data. Currently there are 44 engines of type SR 305-230 in operation. No incident implicating the engine has been reported. The oldest of them has accumulated 763 flight hours. A TBO, however, has not yet been defined. For the achievement of type certificates and supplemental type certificates (STCs) for installation of the SMA diesel in further aircraft types including the Cessna 182, Maule-9 and various Piper models the manufacturer is continuing the cooperation with its partners. Potential candidates for the installation of this powerplant are basically all single and twin-engine aircraft with engine ratings between 200 and 700 hp, according to Deniau. posted at 11:22 AM |
