EAA Experimenter 31 The CD-300 achieved its maiden fl ight in July at Conti- nental's German development center in Altenburg in a Cirrus airframe. The company's fl ying test bed exhibited rates of climb and cruise performance that exceeded engineers' expectations. The CD-300 has gone from "concept to fi rst fl ight in under nine months," according to Continental. Continental has started the type certifi cation process for its 300 series diesel aircraft engines. This will be the sixth jet fuel aircraft engine to be certifi ed by Continental Motors for GA aircraft. The type certifi cation will be conducted in accordance with the requirements of the European Aviation Safety Agency (EASA), followed by FAA and Chinese CAAC validation. The en- gine is expected to be certifi ed in 2016 according to Continental. Together with the debut of the new CD-300 engine, Con- tinental Motors Group (CMG) moves forward with forming a one-stop shop for GA engines under one single brand. The diesel engines, known and sold under the brand name Centu- rion, are renamed to Continental Diesel, abbreviated as "CD." For example, the former Centurion 2.0s is now called CD-155. The diesel products belong now to three engine series: CD-100 series—the Centurion 2.0/2.0s, four-cylinder, in-line engines with 135 and 155 hp CD-200 series—the former Continental TD-300, fl at, diesel engines with 230 and 245 hp CD-300 series—the Continental's newest V-6 diesel will start the CD-300 series with its fi rst product rated at 310 hp. More powerful versions up to 360 hp are likely to be presented in the next year. For more information, visit www.continentalmotors.aero . SMA French diesel-engine manufacturer SMA (Société de Motorisa- tions Aéronautiques) announced that the company is working with Cessna and Lycoming to prepare for deliveries of Cessna's Turbo Skylane 182 JT-A, certifi cation of which is expected this fall. The company's SR305-230E engine currently develops 227 hp in the Skylane installation, but SMA plans to introduce a more powerful version soon. This announcement means that SMA is developing a version in the 265- to 285-hp range. This stronger version of the SR305 engine has already been endur- ance-tested in SMA test cells. Some 90 engines of the SR305 will be delivered by the end of 2014, according to SMA. Last year, SMA presented a six-cylinder concept diesel, the SR460, which is designed to deliver 350 to 400 hp. Since then, the engine has been built, and it has been undergoing bench tests since April 2014. According to SMA, the SR460 prototype engine has fully achieved its expectations. The SR460 engine could be developed and certifi ed within two years. For more information, visit www.SMAengines.com . DELTAHAWK Wisconsin-based DeltaHawk Engines Inc. fl ew a Cirrus SR20 powered by a Jet-A-burning diesel engine to Oshkosh this year. The proof-of-concept prototype is currently undergoing fl ight testing, and the company is aiming for an engine STC as soon as type certifi cation is obtained, expected in 2015. The air- plane had logged 14 hours of fl ight and recently fl ew from Vero Beach, Florida, to Oshkosh. The two-stroke V-4 engine is rated at 180 hp. Test pilots are Nathan Zucker, a Cirrus-certifi cated in- structor, and Doug Doers, DeltaHawk chief technology of cer. "I am very impressed with the DeltaHawk engine," Zucker said. "Through the testing process, the engine has proved to run very smoothly, with minimal vibration. The ef ciency of the engine is remarkable. We completed a 6-hour, nonstop, unrefueled leg, with IFR reserves. This engine has unbeliev- able potential." According to the aircraft owner, John Brooks, the SR20 recorded a fuel burn rate of 7.1 gph during its last fl ights. DeltaHawk claims 30 to 40 percent better fuel ef cien- cy compared to avgas engines. A DeltaHawk-powered Cirrus SR20 at AirVenture 2014. The SMA SR305-230E engine currently develops 227 hp.
