How does dihedral affect an aircraft's stability? This video discusses how dihedral, or the angle of inclination between the wing and the horizontal plane, affects an aircraft's roll stability. Passenger aircraft and general aviation aircraft are characterized by having either a high wing with zero dihedral or a low wing with positive dihedral (i.e., with the wings tilted upward). This is a stable configuration for an aircraft. Indeed, if a lateral disturbance, such as a gust, causes the aircraft to rotate around the roll axis, the downwind wing generates greater lift, which tends to spontaneously return the aircraft to its initial position. Military aircraft, on the other hand, must be intrinsically unstable and for this reason must have wings with negative dihedral. The AV-8 Harrier bomber aircraft in particular has a propulsion system with four orientable nozzles along the fuselage under the wing. Therefore, to avoid interfering with the gas exiting the nozzles, the wing must be positioned high. To make the aircraft unstable, the wing must be designed with negative dihedral. Some military transport aircraft also have a configuration similar to the Harrier. How is this possible? Such large aircraft would be impossible to maneuver without negative dihedral, so excessive stability must be reduced.
