HF120 TURBOFAN ENGINE

WITH GREAT POWER COMES GREAT MOBILITY

The lightweight, fuel-efficient, low-emission HF120 turbofan engine propels HondaJet to the top of its class.

  • A high thrust-to-weight ratio allows for uncommonly long range and large payload.
  • Specialized fluid dynamics software optimizes airflow within the compact engine, maximizing performance.
  • The engine's simple, high-performance combustion chamber keeps emission levels well within requirements for compact jets.
  • Honda created the first ultra-compact Full Authority Digital Electronic Control (FADEC) system for this class of engine. FADEC provides superior operation and reliability without variable mechanisms.
