The most notable innovation of HondaJet are engines mounted on top of the wings on special pylons, and not on the fuselage, as is customary in this category of aircraft. The solution, called OTWEM (engine suspension over the wing), allowed Honda Aircraft designers to free up the cabin space and reduce the noise level from engine vibration. According to the manufacturer, the aerodynamic design of the wings and nose reduces resistance and increases the efficiency of the business jet.
Another important element is the GE Honda Aero HF120 engine itself, which was developed in close collaboration between Honda and GE Aviation — one of the rarest cases where an aircraft manufacturer was involved in an engine development project. Usually engines are developed in accordance with the requirements of the project by specialized companies, without the active actions of the aircraft manufacturer.
HondaJet is the first successful civil aviation project of the Japanese industry in decades. The aircraft was designed by Honda Aircraft, a subsidiary of American Honda Motors, and is manufactured entirely in the United States, in Greensboro, North Carolina.
