Stringers
A stringer is a structural member of the airplane frame that provides longitudinal support to the aircraft. Stringers can be placed along the length of the fuselage, through the span of the wings or in the empennage of the airplane and are made of wood or metal. When coupled with ribs, stringers allow for stress to be transmitted evenly through the body of the plane and provide structural support to the aircraft skin. Generally, stringers number from 50 to 100 in the fuselage portion of the aircraft but when used in reduced numbers (less than 10) are sometimes referred to as longerons. Reducing the number of stringers results in a greater number of ribs necessary to provide the same structural support.
