Turbofan Engine HF120 achieved best-in-class fuel efficiency, environmental performance, and durability

Overview of HF120

HF120 is the next generation of Honda’s HF118 engine technology, which was further enhanced by the General Electric Company (GE) and Honda collaboration. It is a compact engine yet featuring best-in-class weight, fuel efficiency, environmental performance, and durability. Engine sales are conducted by GE Honda Aero Engines.

Compact, lightweight, and high performance

With the simple structure and air flow optimization, the HF120 combined small size and high performance.

Low fuel consumption and noise

The low fuel consumption and noise are the best-in-class, which were achieved by improving the efficiency of each element, such as the engine bypass ratio, and overall system pressure ratio.

Low emission

There were no emission requirements in the engine certification process for the small engines for business jet aircraft, but we developed our own combustion method and developed an environment-friendly engine which meets the emission requirements for large engines.

High durability

Durability was enhanced by optimizing materials and reducing the load on each parts. These enhancements lead to overhaul*3 intervals of 5000 hours, which is one of the longest in the category.

*3 : After an engine is disassembled into parts, all those parts are fully inspected, and reassembled again.
