A fixed-wing aircraft may have more than one wing plane, stacked one above another: Biplane: two wing planes of similar size, stacked one above the other. The biplane is inherently lighter and stronger than a monoplane and was the most common configuration until the 1930s. The very first Wright Flyer I was a biplane.

Flight tests followed quickly, and showed that the Yak-25 was easy to fly, and had exceptional performance and maneuverability for a straight-wing aircraft. Unfortunately it soon became clear that the laminar flow section used for the tail unit was totally unsuitable, with extremely severe buffeting setting in at 500 km/h (310 mph).
Beginning with the successful contract bid in June 1946, the B-52 design evolved from a straight wing aircraft powered by six turboprop engines to the final prototype YB-52 with eight turbojet engines and swept wings. The B-52 took its maiden flight in April 1952. The B-52 has been in service with the USAF since 1955, and NASA from 1959 to 2007 ...
Later aircraft used three-letter designations, the first denoting the engine (except for the two mailplanes), the second denoting the wing installed, S or T meaning Straight or Tapered wing, and the final O indicating it was a derivative of the 10. An -A suffix indicated an armed variant intended for export.
Originally designed with straight wings, problems arose when the long delayed engines proved heavier than originally promised. While waiting for the engines, Messerschmitt moved the engines from the wing roots to underwing pods, allowing them to be changed more readily if needed. That turned out to be important, both for availability and ...
A straight-winged North American FJ-1 flying next to a swept-wing FJ-2 in 1952.. There are three main reasons for sweeping a wing: [1] 1. to arrange the center of gravity of the aircraft and the aerodynamic center of the wing to coincide more closely for longitudinal balance, e.g. Messerschmitt Me 163 Komet and Messerschmitt Me 262.
A cross section of the aircraft with labeled parts. The XP-80 had a conventional all-metal airframe, with a slim low wing and tricycle landing gear.Like most early jets designed during World War II—and before the Allies captured German research data that confirmed the speed advantages of swept-wings—the XP-80 had straight wings, similar to previous propeller-driven fighters.
