With the tips located forward of the point where the wings connect to the fuselage, the plane almost looks as if it is travelling backwards in flight.

Aviation Stack Exchange is a question and answer site for aircraft pilots, mechanics, and enthusiasts. It only takes a minute to sign up. What are the advantages of a forward-swept wing vs. Image credit: NASA. There have only been a few aircraft built with forward-swept wings. Most notably was the X, which you have pictured above.

Over the years, countless wing configurations have been tried and tested. Few have been successful. Learn about the different types of aircraft wing configurations and see how each wing type differs from the other, as well as the pros and cons of each. Aircraft wings are airfoils that create lift when moved rapidly through the air. Aircraft designers have created a variety of wings with different aerodynamic properties. Attached to the body of an aircraft at different angles, these wings come in different shapes. If you are fond of airplanes or interested in learning how planes fly, you may want to learn about different types of aircraft wings or propellers used in aircrafts.

A forward-swept wing is an aircraft wing configuration in which the quarter-chord line of the wing has a forward sweep. Typically, the leading edge also sweeps forward. The forward-swept configuration has a number of characteristics which increase as the angle of sweep increases. The rearward location of the main wing spar would lead to a more efficient interior arrangement with more usable space. Air flowing over any swept wing tends to move spanwise towards the rearmost end of the wing. On a rearward-swept wing this is outwards towards the tip, while on a forward-swept wing it is inwards towards the root.

Design Process: Cantilever Wings

Last month we began our discussion of the structural layout of the wing with a look at externally braced wings. We now turn our attention to cantilever wings. The majority of modern airplanes have cantilever wings because the drag penalty of external wing bracing is excessive for their mission. On a cantilever wing, all of the loads are borne on structural elements that fit entirely within the airfoil contour of the wing. The wing will incorporate one or more full-span spars that carry the primary bending load. There are two approaches to giving the wing sufficient torsional stiffness to withstand the torsion produced by the ailerons, flaps and the other aerodynamic forces that tend to twist the wing. It is possible to use a single tubular or box spar that is stiff enough in torsion to carry the twisting loads as well as the wing bending.

Within the frame of the NLF path a short and medium range transport aircraft with forward swept laminar wing was designed. The present paper is focused on the aerodynamic design of the forward swept wing in cruise flight. The resulting wing was assessed on overall aircraft level with respect to its fuel reduction potential, whereby the CSR configuration, essentially a re-design of the Airbus A, was used as a reference. Laminarization of boundary layers on wing, empennage and engine nacelles of transport aircraft has undoubtedly the highest potential for improving the aerodynamic performance. But before this technology can find its way into series production and become fully operational a bunch of scientific issues have to be resolved. Aerodynamics is inherently the key driver for development of laminar technology on transport aircraft. Consequently, throughout the past decades the basic problems regarding laminar to turbulent transition on transonic swept wings have been investigated thoroughly and flow control methodologies capable of delivering large portions of laminar boundary layer flow are well understood [ 2 ].

9 Types of Aircraft Wings in Depth

A swept wing is a wing that angles either backward or occasionally forward from its root rather As the pressure waves converge the air in front of the aircraft begins to compress. This creates a Thus swept-forward wings are unstable in a fashion similar to the low-speed problems of a conventional swept wing.

A B Stratofortress showing wing with a large sweepback angle. A swept wing is a wing planform favored for high subsonic and supersonic speeds, and is found on almost all jet aircraft in one form or another, as well as some high speed propeller aircraft. Compared with straight wings common to slower aircraft, they have a "swept" wing root to wingtip direction angled beyond usually aftward the spanwise axis.

Stability & control of a forward swept wing Aircraft

Swept wing

By Collimatrix , March 9, in Aviation. Every so often someone asks a question about the advantages of forward-swept wings, and usually they get a shitty half-assed answer about how they somehow improve maneuverability and stuff. I will attempt to provide a fully-assed answer.

Идти приходилось плечо к плечу, носок в пятку. У испанцев всегда было иное представление о плотности, чем у остального мира. Беккер оказался зажат между двумя полными женщинами с закрытыми глазами, предоставившими толпе нести их в собор. Они беззвучно молились, перебирая пальцами четки. Когда толпа приблизилась к мощным каменным стенам почти вплотную, Беккер снова попытался вырваться, но течение стало еще более интенсивным. Трепет ожидания, волны, сносившие его то влево, то вправо, закрытые глаза, почти беззвучное движение губ в молитве.

Сьюзан многим ему обязана; потратить день на то, чтобы исполнить его поручение, - это самое меньшее, что он мог для нее сделать. К сожалению, утром все сложилось не так, как он планировал. Беккер намеревался позвонить Сьюзан с борта самолета и все объяснить. Он подумал было попросить пилота радировать Стратмору, чтобы тот передал его послание Сьюзан, но не решился впутывать заместителя директора в их личные дела. Сам он трижды пытался связаться со Сьюзан - сначала с мобильника в самолете, но тот почему-то не работал, затем из автомата в аэропорту и еще раз - из морга.

Коммандер, пытаясь приоткрыть дверь, прижал лицо вплотную к узенькой щелке. - Господи Боже мой, Сьюзан, с тобой все в порядке. Она встала на ноги и расправила платье. - Все обошлось. Сьюзан огляделась. Третий узел был пуст, свет шел от работающих мониторов. Их синеватое свечение придавало находящимся предметам какую-то призрачную расплывчатость.

 Не знаю… - В голосе слышалась нерешительность.  - Я бы только… - Не надо спешить, друг. Мне стыдно это говорить, но полиция у нас в Севилье далеко не так эффективна, как на севере. Паспорт этому человеку вернут только через несколько дней. Если вы назовете мне его имя, я сделаю все, чтобы он получил свой паспорт немедленно. - Да что вы… Мне кажется, что… - Зашелестели перелистываемые страницы.  - Имя немецкое.

Беккер закрыл глаза и попытался сосредоточиться. Итак, каков следующий шаг.

Немец не хотел его оскорбить, он пытался помочь. Беккер посмотрел на ее лицо. В свете дневных ламп он увидел красноватые и синеватые следы в ее светлых волосах. - Т-ты… - заикаясь, он перевел взгляд на ее непроколотые уши, - ты, случайно, серег не носила. В ее глазах мелькнуло подозрение.

Голос шефа из смешливого вдруг стал жестким: - Сьюзан, я звоню потому, что ты нужна мне .
