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.
The converted Eagle 407HP is on display here at Heli-Expo (Booth No. 8428). The company has signed a technology license agreement with Bell Helicopter and Honeywell to help develop the supplemental type certificate conversion.
