Hill Helicopters has introduced a new turbine engine design intended for use with its HX50 helicopter, which is also under development. According to the company, the GT50 engine will feature Hill’s FADEC system, a direct-drive starter-generator, redundant electrical engine ancillaries and a modular design. Weighing in at 200 pounds, it is expected to provide a maximum continuous power of 400 HP, fuel consumption of 35 GPH and TBO of 5,000 hours or 20,000 cycles.
“By developing the engine in parallel with the helicopter, we were able to define exactly what attributes were required for the powerplant in order to deliver the payload, performance, package and engine control characteristics essential to the HX50, rather than having to accept a poorly suited and unnecessarily expensive old technology engine,” the company said.
As previously reported by AVweb, Hill Helicopters unveiled its clean-sheet HX50 helicopter design last August. The company says the HX50 will have a top cruise speed of 140 knots, 1,760-pound payload and range of 700 NM. Hill is currently aiming to have the design in production in 2023.
