Brake 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.

Eagle Copters of Calgary, Alberta (Booth No. 3717) said development and testing of its Bell 407 HP engine-conversion program was proceeding and that the company expected Transport Canada and FAA approval next year. Mike Mallon, Eagle Copters director of maintenance, said the company had yet to set a price for the conversion, but was striving to keep costs down by using as many original 407 components as possible, including cowling inlets and drive shafts.

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.
