Laminar flow refers to the smooth air flow on the boundary layer of areas such as an aircraft's wings. Laminar flow significantly reduces wind drag compared to a turbulent airflow. Honda's uniquely developed natural laminar flow wing and nose design allows air to flow naturally across the boundary layer, creating a large laminar flow even at high speeds. This design contributes to the HondaJet's outstanding flight speed and fuel efficiency.
Laminar flow is prone to disturbance by even the smallest ridges in the external panels and rivets. The HondaJet's design optimizes the number and position of rivets and employs a skin (external panel) of integrally machined aluminum for the main wings to reduce surface irregularities to an absolute minimum. These innovations led to the creation of a natural laminar flow wing and nose that are effective even at high speeds.
