Specific fuel consumption

February 26, 2014 - 5:30pm

Eagle Copters has resumed work on the Eagle 407HP conversion that retrofits the Honeywell HST900D-2 engine into the Bell 407 in place of the stock Rolls Royce C47. The Honeywell engine maintains power through higher altitudes, according to Eagle, improving payload capacity by 40 percent at 12,000 feet while reducing specific fuel consumption and delivering a 22 percent better power output than the stock engine in high/hot conditions. The new engine also offers e an 8 percent reduction in takeoff and 10 percent lower max cruise specific fuel consumption.

Williams International announced on Tuesday that its FJ44-3AP turbofan has gained EASA type approval. The 3,502-pound-thrust engine, which received FAA certification last May, powers the Nextant 400XT. Compared with the FJ44-3, the -3AP has 8 percent more takeoff thrust and 13 percent more cruise thrust, while weight was reduced 3 percent and cruise specific fuel consumption improved by 1.5 percent.

PD30 geared turbofan

The Kuznetsov design bureau, part of the United Engine Corporation (ODK), unveiled a new geared turbofan design at the Engines 2000 exhibition in Moscow last month. The PD30 is proposed for an upgrade to the Antonov An-124 Ruslan heavy airlifter, which is currently powered by the Ukrainian Ivchenko Progress D18T. The PD30 could also power Russia’s proposed widebody airliner, known as Airplane 2020.

GE Aviation, while it may still be associated largely with commercial and military powerplants, has been focusing its gaze on the business aviation market over the past several years.

Shawn O’Day, head of the company’s business and general aviation marketing, told AIN that although business aviation has historically been a segment of opportunity for GE, it is an area where the engine and systems maker sees potential. In fact, the company signaled its intention to expand its business and general aviation footprint at last year’s Paris Air Show.

HyperMach SonicStar

HyperMach’s planned 20-seat supersonic business jet (SSBJ)–SonicStar–will be able to fly at speeds up to Mach 4.0, the company said on Friday. This is faster than the Mach 3.6 top speed announced when the V-tailed aircraft was first revealed at June’s Paris airshow.

Turbomeca plans to reduce the specific fuel consumption (SFC) of its turboshaft engines by 37 percent by 2030, and at the Helitech 2011 show discussed the strategies it is implementing to accomplish that change. While the company plans to make changes to the engine machinery, it expects much of the reduction to come from engine-airframe integration and new practices that make more efficient use of the engine.

GE Aircraft (Stand 358), whose TechX engine Bombardier selected to power its under-development Global 7000 and Global 8000 ultra-long-range business jets, has rebranded the big turbofan as the “Passport.”

French startup company Price Induction is studying an engine with a two-stage contra-rotating fan as a way to reduce fuel burn on very light jets. The Taor 380-1 would have a thrust of 720 pounds and cut fuel burn by 20 percent, compared with the company’s DGen 380 conventional turbofan engine. The latter claims a specific fuel consumption of 0.715. The Taor 380-1 would be suited to 4,400-pound-mtow aircraft, enabling speeds of 250 knots.

Price Induction, a startup company based in Anglet, France, is studying a 560-lb-thrust high-bypass-ratio turbofan that would establish a new thrust class. Applications of the DGEN380 would be four-seaters, allowing pilots to upgrade from piston singles to twinjets. Another market could be airline-pilot training.

Higher-than-expected engine fuel consumption is causing a six-month delay, to this March, in certification of the Dassault Falcon 2000EX. According to the French manufacturer, the increased fuel consumption of the Pratt & Whitney Canada PW308C turbofan has also prompted an increase in the airplane’s fuel capacity and mtow to preserve range guarantees. Delivery plans remain on schedule.
