Design

Larger than most UAVs, the WZ-7 features a tandem, joined-wing design, which allows for a more rigid, less flexible wing than other configurations, with benefits said to include an increased
lift-to-drag ratio In aerodynamics, the lift-to-drag ratio (or L/D ratio) is the lift generated by an aerodynamic body such as an aerofoil or aircraft, divided by the aerodynamic drag caused by moving through air. It describes the aerodynamic efficiency under give ...
