Its designers gave it an extremely large vertical tail, thought necessary because of fears that the large delta wing might block airflow to the tail and make the plane impossible to control. The XF-92A first flew from Muroc Air Base (later Edwards Air Force Base) in 1948. The company's engineers began testing models in wind tunnels before building a full-size aircraft. manufacturer of bombers, began work on a supersonic interceptor aircraft with a delta wing. Soon after the end of the war, Convair, a U.S. Army Air Forces, the predecessor to the U.S. Lippisch also came to the United States where he worked on supersonic flight for the U.S. The Allies captured the unflown glider at the end of the war and sent it to the United States for study. He chose the delta shape and constructed a wooden glider to be launched from high altitude by a transport plane. Lippisch of Germany, best known for developing the Messerschmitt Me 163 Komet rocket fighter, began thinking about supersonic airplanes during the 1940s. Like many advanced concepts, not until the combatants in World War II conducted actual wind tunnel tests did large numbers of aircraft designers start to take the delta wing seriously. Their aircraft design would have used a jet-propulsion system, with thrust provided by rockets, compressed air jets, steam, or gunpowder, had it ever flown. The first patent for a delta-wing aircraft design was granted to Englishmen J.W.
Their primary advantage is efficiency in high-speed flight. Despite the fact that paper airplanes have delta wings and appear to fly quite well when launched from a height, delta wings actually perform poorly at low speeds and often are unstable (i.e., they do not stay in level flight on their own). Often delta-wing airplanes lack horizontal stabilizers. It sweeps sharply back from the fuselage with the angle between the leading edge (the front) of the wing often as high as 60 degrees and the angle between the fuselage and the trailing edge of the wing at around 90 degrees. The delta wing story provides an excellent example.Ī delta wing is a wing whose shape when viewed from above looks like a triangle, often with its tip cut off.
Sometimes, a technology persists despite its problems and eventually is rescued by other technologies. The delta wings can easily be seen on this photograph of the Shuttle orbiter Columbia.
