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.
