Over-The-Wing Engine Mount (OTWEM)

Because of ground distance, most business jets cannot place their engines under the wing like large airliners. Meanwhile, it was once believe that aircraft engines could not be placed above the main wing, as this would interrupt a clean airflow over the wing surface and as a result, increase interference drag and inhibit lift. This is why most business jets have their engines at the rear of the fuselage. But rear mounted engines present disadvantages such as less cabin space, greater cabin noise, and poor aerodynamic performance.

In 1997, lead HondaJet designer Michimasa Fujino developed a new breakthrough in aviation technology that allowed aircraft engines to be placed above the main wing, all while improving aerodynamics. He soon patented his discovery, making the HondaJet the first business jet in the world to successfully develop an Over-The-Wing Engine Mount. Thanks to the OTWEM technology, the HondaJet can fly faster, higher, and further than other aircraft in its class, all while featuring a quieter and more spacious cabin.

Greater Fuselage Space

The rear-mounted engines used on other business jets require support structures to be installed in the fuselage to support the weight of the engines. This limits the amount of passenger room and baggage space. With its Over-The-Wing Engine Mount, the HondaJet requires no engine support structure inside the fuselage. This gives the HondaJet up to 20% more cabin space than similar sized business jets, which means more passenger legroom, more room for luggage, and enough space for a fully private lavatory with skylights.

Tranquil Cabin

By moving the engines from the fuselage to the wing, the HondaJet minimizes the sound and vibration transmitted to the passengers, maximizing cabin comfort. This makes the HondaJet perfect for business travelers who need to catch up on work, or on sleep.

Improved Aerodynamics

When aircraft fly at high speeds, the air flow on the upper surface of the main wing becomes faster, which produces shock waves and increases air resistance. The HondaJet's engines are placed in such a way that the airflow over the wing is combined with that around the engines, reducing air resistance at high speeds (wave drag), and letting the HondaJet fly faster than similar sized aircraft.

Additionally, less air resistance means less fuel consumption, making the HondaJet a better choice for the environment, and for the bottom line.
