Two powered, forward-swept wing aircraft, both of German design, are known to have been built to take advantage of these improvements. These aircraft include the World War II vintage Junkers Ju. Due to the various disadvantages of delta wings considered there was a need for improvement which led to the development of compound delta wings. In compound delta wings a more highly swept delta wing is added in front of the main delta wing. This creates a controlled vortex and further reduces the drag. Characteristics.

This book is a translated edition of Die Pfeilfl elentwicklung in Deutschland bis The history of the development of the swept wing has been described several times during the last fifty years.
But there has been detailed description of how the original idea of the swept wing was developed into the reality that enabled highspeed flight. Forward-Swept Wings. Brief History. Forward-swept wings are not a new concept, but one developed by Germans during World War II. At that point, a German engineer named Hans Wocke was the head of the bureau to explore the benefits of forward-swept wings.
The new wing promised German fighter aircraft a speed advantage in comparison to their opponents. In lateHubert Ludwieg carried out the first swept-wing measurements at AVA. Busemann had, in the meantime, become head of the new German Institute of Aviation Research (Deutsche Forschungsanstalt für Luftfahrt; DFL) in Braunschweig.
Important contributions of German aeronautical research to the flight sciences are, for example, the boundary-layer theory (), the lifting-wing theory (), the Wagner Web (), the boundary-layer stability theory (), the swept wing () and its experimental verification (), the axial compressor (minimum frontal area) for jet 3/5(2).
A swept wing is a wing that angles either backward or occasionally forward from its root rather than in a straight sideways direction. Swept wings have been flown since the pioneer days of aviation.
Wing sweep at high speeds was first investigated in Germany as early as by Albert Betz and Adolph Busemann, finding application just before the end of the Second World War.
The swept-wing concept had been appreciated by German aerodynamicists since the mids, and by a considerable amount of research had gone into it. However, in the United States and Great Britain, the concept of the swept wing remained virtually unknown until the end of the war.
Indesigners for the Messerschmitt firm, builders of the remarkable Me jet fighter, realized the potential of swept wing aircraft and studied Busemann's paper more intently. Following promising wind tunnel tests, Messerschmitt had a swept wing research plane under development, but the war ended before the plane was finished.
These were derived from the same engines then being used on German Me jet fighters. The Horten XVIIIA was in effect a spinoff of the Horten brother’s wooden Ho flying-wing. The U.S. Army Air Forces had captured the flying wing prototype—along with hundreds of other German aircraft—near the end of World War II.
In AprilGeorge Patton’s Third Army found four steel-and-wood Horten prototypes; of three airframes, the V3 was. The Forward Swept Wing (FSW) concept is not entirely new and has in fact been used by design engineers since World War II (Johnson et al.
The Luftwaffe‟s Junkers JuV1 was a test bed for a jet-powered bomber that could escape allied fighters. The initial development began inwhere favourable aerodynamic performance.
Delta Wings A variation on the swept wing theme is the delta wing first proposed by the German aerodynamicist Alexander Lippisch in the years prior to World War II (ref. This wing derives its name from the Greek letter, which describes the planform shape.
A wing plan form in which the wings are swept forward (i.e., the tips of the wing are ahead of the roots, unlike in swept-back wings). This plan form enjoys the same advantages as a swept-back wing but requires a lesser sweep. The wing performs better at subsonic speeds and near transonic speeds than a swept-back wing.
A delta wing is a wing shaped in the form of a triangle. It is named for its similarity in shape to the Greek uppercase letter delta (Δ).
Although long studied, it did not find significant applications until the Jet Age, when it proved suitable for high-speed subsonic and supersonic the other end of the speed scale, the Rogallo flexible wing proved a practical design for the hang.
The introduction of the German swept wing research to aeronautics caused a minor revolution, especially after the dramatic successes of the B and F Eventually almost all design efforts immediately underwent modifications in order to incorporate a swept wing.
The classic Boeing B, designed in the s, would remain in service until. The Development of the All-Wing Aircraft [This is an abridged version of the 35th Wilbur Wright Memorial Lecture, which Jack Northrop read to the Royal Aeronautical Society on It remains his major statement of his all-wing aircraft.
Problems with its engines hindered its development early on, but by the XPA could go mph at 35, feet. That put it nearly on par. Busemann belonged to the famous German school of aerodynamicists led by Ludwig Prandtl, a group that included Theodore von Karman, Max M.
Munk, and Jakob Ackeret. however, to propose the use of swept wings to overcome the problems of transonic and supersonic flight and the first to propose a drag-free system of wings subsequently known as.
Consider the case of a swept wing with an NACA 64A airfoil, a quarter-chord sweep Λ c /4 = 45 o, taper ratio λ =and aspect ratio A = 5 operating at M = and a chord-based Reynolds number Re c = 2 million. The leading edge sweepback may be found by using Equation () as follows. Werner Krüger () was a German engineer who invented the Krueger flap in He evaluated Krueger (Krüger) flaps in the wind tunnels of Göttingen Aerodynamische Versuchsanstalt, AVA in Krueger flaps are aircraft lift enhancement devices fitted under the leading edge of an aircraft wing where a portion of the lower wing is rotated out in front of the main wing leading edge.
The result was a series of advanced designs, some using swept wings for improved transonic performance, others instead using the tailless design to lower drag to the same end. Since German aircraft engineers were aware that tailless designs might encounter serious stability problems at transonic speeds, much as the prototype Me B V18 did on July 6,in hitting a record 1, km/h ( The JU book will probably become the definitive work on this historically significant Luftwaffe jet bomber, and completely explains all facets of the origins, design, construction, flight testing, and subsequent development of the JU The authors begin with a discussion of the origins of the swept forward wing, going back to pre-Wright.
The swept wing immediately went to the top of design priorities for high-speed flight. In the U.S., North American redesigned the XP as a sweptwing airplane; Boeing did the same with a new design that emerged as the XB; and Douglas, at Navy request, split the D program into two phases: the straight-wing turbojet-powered D Skystreak and the sweptwing jet-and-rocket-powered D The introduction of the German swept wing research to aeronautics caused a minor revolution, especially after the dramatic successes of the B and F Eventually almost all design efforts immediately underwent modifications in order to incorporate a swept wing.
This volume continues Classic's series looking at various German aircraft and covers one of the most unusual of them all - the Juand the concept of the swept forward wing. Chapter one looks at swept forward wing aircraft development from to Nineteenth and early twentieth century aircraft designers often seem to have copied from.
Hans Multhopp (17 May – 30 October ) was a German aeronautical engineer/ing a degree from the University of Göttingen, Multhopp worked with the famous designer Kurt Tank at the Focke-Wulf Flugzeugbau AG during World War II, and was the leader of the team responsible for the design of the Focke-Wulf Ta lightweight jet fighter, which was the winner.
Reply German aircraft in Russia. The Junkers Juthe jet bomber with forward swept wings was taken by the Soviets.
It was flown in the USSR and an improved version was built. Many Technitions and Engineers were brought back as 'guests' Soviet Union and were forced to work for the Soviet masters.
Landser Visitor (9/17/01 pm. Its wings, with anhedral and 35 degrees of sweep, combined German and Russian swept-wing research. Initial production aircraft, which entered service in latewere powered by a Klimov RD or VK-l turbojet, developed in Russia from examples of the Rolls-Royce Nene which, innocently, Britain had sold to the USSR in An oblique wing (also called a slewed wing) is a variable geometry wing concept.
On an aircraft so equipped, the wing is designed to rotate on center pivot, so that one tip is swept forward while the opposite tip is swept aft. back-swept wings, this corresponds to a stall occurring at the wing tips, resulting in a loss of aileron control.
In the case of forward-swept wings, however, stall occurs ﬁrst at the wing. The wave drag is much less for swept wings, roughly in proportion to the aspect ratio. So when you are trying to push the plane to Mach 1, swept wings make your job easier. At Mach 1 and a bit higher more and more of the wing region experiences supersonic flow, and the shock drag is dominant.

Stanewsky, Trans.). In German Development of the Swept Wing (pp. American Institute of. With a swept wing the same happens, but now the flow will not stay at one wing section but show an added sideways component. Again, air is sucked into the low pressure area, but because that area is a little to the side of the direction of motion of the wing, the flow lines will initially move towards the center of the wing on the upper side in.
The wing, in many ways, is doing what a bird’s wing does in flight; evolution hasn’t yet felt the need to put an upright tail on a bird, after all. “The Ho was decades ahead of its time.
A straight wing is most efficient for low-speed flight, but for an aircraft designed for transonic or supersonic flight it is essential that the wing is swept.
Most aircraft that travel at those speeds usually have wings (either swept wing or delta wing) with a fixed sweep are simple and efficient wing designs for high speed flight, but there are performance tradeoffs.The Horten HX-2 "flying wing," developed from a German World War II fighter plane concept, is now ready to fly.
