Design and development of the HondaJet

The HondaJet is an advanced, lightweight, business jet featuring an extra large cabin, high fuel efficiency, and high cruise speed compared to existing small business jets. To achieve the high-performance goals, an over-the-wing engine-mount configuration, a natural-lamina-flow wing, and a natural-laminar-flow fuselage nose were developed through extensive analyses and wind-tunnel tests. The wing is metal, having an integral, machined skin to achieve the smooth upper surface required for natural laminar flow. The fuselage is constructed entirely of composites; the stiffened panels and the sandwich panels are cocured integrally in an autoclave to reduce weight and cost. The prototype aircraft has been designed and fabricated. Major ground tests such as structural proof tests, control-system proof test, system function tests, and ground-vibration tests have been completed. The first flight was conducted on 3 December 2003, and flight testing is currently underway. The aerodynamic, aeroelastic, structural, and systems designs and tests conducted during the development are described.
