Engine Overview
High-flow, wide-chord fan blades, high temperature materials and advanced features are expected to provide real performance advantages, like a high thrust-to-weight ratio and reduced fuel burn. With a time between overhaul at 5,000 hours and no need to open the engine for interim hot-section inspections, the HF120 is designed to stay on-wing over 40% longer than other business jet engines.
By reducing weight and incorporating innovative 3D aerodynamic designs, the engine components are designed to interact with greater efficiency while optimizing operability. The HF120 will use a sophisticated combustor and fuel nozzles designed to reduce NOx, CO, HC and smoke emissions. The HF120 is designed to meet noise levels quieter than Stage 4 requirements with substantial margin.
The HF120 builds upon five generations of research and development and will integrate commercially proven designs and materials. It is expected to enter service fully mature from an extensive testing program, with a target of more than 15,000 hours in testing.
