The HondaJet is setting itself apart from traditional business jets with its Over-The-Wing Engine Mount (OTWEM) design. Unlike the conventional engine placement at the rear of the fuselage, this innovative design enhances cabin space by eliminating the need for large support structures within the fuselage. The OTWEM configuration also contributes to reduced noise and vibration levels inside the cabin, improving passenger comfort.
The aerodynamic advantages of this engine placement include minimized shockwaves and drag at high speeds, leading to higher cruise speeds and better fuel efficiency. Honda Aircraft Company received Tier-6 Sustainable Flight Department Accreditation from the National Business Aviation Association (NBAA) in October 2024 for these advancements.
The Natural Laminar Flow (NLF) design employed in shaping the nose and wings further enhances performance by reducing turbulent airflow, thus improving speed and fuel efficiency. The aircraft’s exterior minimizes disruptions to airflow through careful design choices like integrally machined aluminum skin on the wings.
Honda’s approach to constructing the airframe involves using carbon composites, creating a strong yet lightweight structure that supports high-altitude operations where thinner air reduces drag. This design not only aids in fuel efficiency but also provides a smooth flight experience by avoiding most turbulence.
The HondaJet is powered by two HF120 engines developed through a joint venture between GE Aerospace and Honda Aero Engines. These engines are compact yet powerful, meeting or exceeding emissions standards set by aviation authorities. According to GE Honda Aero Engines, “Two of the world’s most respected names in propulsion have come together to design and manufacture engines for the next generation of very light jets.”
The cockpit features advanced avionics such as Garmin G3000 all-glass displays, facilitating single-pilot operation while ensuring pilot comfort with ergonomic designs. The cabin offers spacious seating arrangements and amenities like a private lavatory.
Michimasa Fujino played a pivotal role in conceptualizing the OTWEM during his tenure at Honda Aircraft Company. His idea laid down a foundation for what would become an iconic aspect of HondaJet’s design evolution.
Since receiving FAA Type Certification in 2015, over 250 HondaJets have been delivered worldwide, covering North America, Europe, Latin America, Southeast Asia, China, India, Japan, and more. As quoted on GE Aerospace: “I still have my original sketch of our business jet,” said Michimasa Fujino.
The technical specifications highlight its class-leading attributes: it boasts an overall length of 42.6 ft., a maximum cruise speed of 483 mph (422 knots), and can reach altitudes up to 43,000 ft.
In summary, with ongoing innovations exemplified by models like the HondaJet Elite II—named “Coolest Thing Made in NC” upon its rollout—the company reiterates its commitment: “Honda Aircraft continues to be committed to improving lives through personal mobility while living in a sustainable society.”
