http://en.wikipedia.org/wiki/Grumman_X-29
The Grumman X-29 was an experimental aircraft that tested a forward-swept wing, canard control surfaces, and other novel aircraft technologies. The aerodynamic instability of this arrangement increased agility but required the use of computerized fly-by-wire control. Composite materials were used to control the aeroelastic divergent twisting experienced by forward-swept wings, also reducing the weight. Developed by Grumman, the X-29 first flew in 1984 and two X-29s were flight tested over the next decade...
Design and development
Two X-29As were built by Grumman from two existing Northrop F-5A Freedom Fighter airframes (63-8372 became 82-0003 and 65-10573 became 82-0049) after the proposal had been chosen over a competing one involving a General Dynamics F-16 Fighting Falcon. The X-29 design made use of the forward fuselage and nose landing gear from the F-5As with the control surface actuators and main landing gear from the F-16. The technological advancement that made the X-29 a plausible design was the use of carbon-fiber composites. The wings of the X-29, made partly of graphite epoxy, were swept at more than 33 degrees forward. The Grumman internal designation for the X-29 was "Grumman Model 712" or "G-712".
The X-29A demonstrated high maneuvering and control in flight testing. A maximum angle of attack of 67° was reached. The configuration, combined with a center of gravity well aft of the aerodynamic center, made the craft inherently unstable. Stability was provided by the computerized flight control system making 40 corrections per second. The flight control system was made up of three redundant digital computers backed up by three redundant analog computers; any of the three could fly it on its own, but the redundancy allowed them to check for errors. Each of the three would "vote" on their measurements, so that if any one was malfunctioning it could be detected. It was estimated that a total failure of the system was as unlikely as a mechanical failure in an airplane with a conventional arrangement.
Aeroelastic considerations
In a forward swept wing configuration, the aerodynamic lift produces a twisting force which rotates the wing leading edge upward. This results in a higher angle of attack, which increases lift, twisting the wing further. This aeroelastic divergence can quickly lead to structural failure. With conventional metallic construction, a torsionally very stiff wing would be required to resist twisting; stiffening the wing adds weight, which may make the design unfeasible.
The X-29 design made use of the anisotropic elastic coupling between bending and twisting of the carbon fiber composite material to address this aeroelastic effect. Rather than using a very stiff wing, which would carry a weight penalty even with the relatively light-weight composite, the X-29 used a laminate which produced coupling between bending and torsion. As lift increases, bending loads force the wing tips to bend upward. Torsion loads attempt to twist the wing to higher angles of attack, but the coupling resists the loads, twisting the leading edge downward reducing wing angle of attack and lift. With lift reduced, the loads are reduced and divergence is avoided.
Operational history
The first X-29 was taken aloft on 14 December 1984 from Edwards AFB with Grumman's Chief Test Pilot Chuck Sewell at the controls. With that flight, the X-29 became the second jet-powered aircraft to fly with forward swept wings (with the Nazi Germany-era Junkers Ju 287, which first flew in 1944, being the first)... The NASA test program continued from 1984 to 1991...

Russia's unique forward-swept wing jet trainer SR-10 is passing tests with the Russian Aerospace Forces in the Moscow Region.
The plane's name can be explained as "jet with wing sweep —10°", which reflects the aircraft's main constructional feature — the moderately forward-swept wings facilitating stability and maneuverability at low speeds.
This subsonic, single engine, all-composite plane meets the needs of unexperienced pilots who will later change it for the Yak-130 — a sophisticated trainer which is in fact a full-fledged combat plane wanted by a number of countries for their air forces.

A swept wing is a wing planform favored for high subsonic jet speeds first investigated in Germany from 1935 onwards until the end of the Second World War. Since the introduction of the MiG-15 and North American F-86 which demonstrated a decisive superiority over the slower first generation of straight-wing jet fighters during the Korean War, swept wings have become almost universal on all but the slowest jets (such as the A-10). Compared with straight wings common to propeller-powered aircraft, they have a "swept" wing root to wingtip direction angled beyond (usually aftward) the spanwise axis. This has the effect of delaying the drag rise caused by fluid compressibility near the speed of sound as swept wing fighters such as the F-86 were among the first to be able to exceed the speed of sound in a slight dive, and later in level flight.
Unusual variants of this design feature are forward sweep, variable sweep wings and pivoting wings. Swept wings as a means of reducing wave drag were first used on jet fighter aircraft. The four-engine propeller-driven Tu-95 aircraft also has swept wings.

A wing is an appendage with a surface that produces lift for flight or propulsion through the atmosphere, or through another gaseous or liquid fluid. A wing is an airfoil, which has a streamlined cross-sectional shape producing a useful lift to drag ratio.
The word "wing" from the Old Norse vængr for many centuries referred mainly to the foremost limbs of birds (in addition to the architectural aisle.) But in recent centuries the word's meaning has extended to include lift producing appendages of insects, bats, pterosaurs, boomerangs, some sail boats and aircraft.
"Wing" can also mean an inverted airfoil on a race car that generates a downward force to increase traction.
Various species of penguins and other flighted or flightless water birds such as auks, cormorants, guillemots, shearwaters, eider and scoter ducks and diving petrels are avid swimmers, and use their wings to propel through water.
A wing's aerodynamic quality is expressed as its lift-to-drag ratio. The lift a wing generates at a given speed and angle of attack can be one to two orders of magnitude greater than the total drag on the wing. A high lift-to-drag ratio requires a significantly smaller thrust to propel the wings through the air at sufficient lift.

SR-10: Unique Russian Forward-Swept Wing Jet Trainer Passes Tests
Russia's unique forward-swept wing jet trainer SR-10 is passing tests with the Russian Aerospace Forces in the Moscow Region. The plane's name can be explained as "jet with wing sweep —10°", which reflects the aircraft's main constructional feature — the moderately forward-swept wings facilitating stability and maneuverability at low speeds. This subsonic, single engine, all-composite plane meets the needs of unexperienced pilots who will later change it for the Yak-130 — a sophisticated trainer which is in fact a full-fledged combat plane wanted by a number of countries for their air forces.

http://en.wikipedia.org/wiki/Grumman_X-29
The Grumman X-29 was an experimental aircraft that tested a forward-swept wing, canard control surfaces, and other novel aircraft technologies. The aerodynamic instability of this arrangement increased agility but required the use of computerized fly-by-wire control. Composite materials were used to control the aeroelastic divergent twisting experienced by forward-swept wings, also reducing the weight. Developed by Grumman, the X-29 first flew in 1984 and two X-29s were flight tested over the next decade...
Design and development
Two X-29As were built by Grumman from two existing Northrop F-5A Freedom Fighter airframes (63-8372 became 82-0003 and 65-10573 became 82-0049) after the proposal had been chosen over a competing one involving a General Dynamics F-16 Fighting Falcon. The X-29 design made use of the forward fuselage and nose landing gear from the F-5As with the control surface actuators and main landing gear from the F-16. The technological advancement that made the X-29 a plausible design was the use of carbon-fiber composites. The wings of the X-29, made partly of graphite epoxy, were swept at more than 33 degrees forward. The Grumman internal designation for the X-29 was "Grumman Model 712" or "G-712".
The X-29A demonstrated high maneuvering and control in flight testing. A maximum angle of attack of 67° was reached. The configuration, combined with a center of gravity well aft of the aerodynamic center, made the craft inherently unstable. Stability was provided by the computerized flight control system making 40 corrections per second. The flight control system was made up of three redundant digital computers backed up by three redundant analog computers; any of the three could fly it on its own, but the redundancy allowed them to check for errors. Each of the three would "vote" on their measurements, so that if any one was malfunctioning it could be detected. It was estimated that a total failure of the system was as unlikely as a mechanical failure in an airplane with a conventional arrangement.
Aeroelastic considerations
In a forward swept wing configuration, the aerodynamic lift produces a twisting force which rotates the wing leading edge upward. This results in a higher angle of attack, which increases lift, twisting the wing further. This aeroelastic divergence can quickly lead to structural failure. With conventional metallic construction, a torsionally very stiff wing would be required to resist twisting; stiffening the wing adds weight, which may make the design unfeasible.
The X-29 design made use of the anisotropic elastic coupling between bending and twisting of the carbon fiber composite material to address this aeroelastic effect. Rather than using a very stiff wing, which would carry a weight penalty even with the relatively light-weight composite, the X-29 used a laminate which produced coupling between bending and torsion. As lift increases, bending loads force the wing tips to bend upward. Torsion loads attempt to twist the wing to higher angles of attack, but the coupling resists the loads, twisting the leading edge downward reducing wing angle of attack and lift. With lift reduced, the loads are reduced and divergence is avoided.
Operational history
The first X-29 was taken aloft on 14 December 1984 from Edwards AFB with Grumman's Chief Test Pilot Chuck Sewell at the controls. With that flight, the X-29 became the second jet-powered aircraft to fly with forward swept wings (with the Nazi Germany-era Junkers Ju 287, which first flew in 1944, being the first)... The NASA test program continued from 1984 to 1991...

In a forward swept wing configuration, the aerodynamic lift produces a twisting force which rotates the wing leading edge upward. This results in a higher angle of attack, which increases lift, twisting the wing further. This aeroelastic divergence can quickly lead to structural failure. With conventional metallic construction, a torsionally very stiff wing would be required to resist twisting; stiffening the wing adds weight, which may make the design unfeasible.
The X-29 design made use of the anisotropic elastic coupling between bending and twisting of the carbon fiber composite material to address this aeroelastic effect. Rather than using a very stiff wing, which would carry a weight penalty even with the relatively light-weight composite, the X-29 used a laminate which produced coupling between bending and torsion. As lift increases, bending loads force the wing tips to bend upward. Torsion loads attempt to twist the wing to higher angles of attack, but the coupling resists the loads, twisting the leading edge downward reducing wing angle of attack and lift. With lift reduced, the loads are reduced and divergence is avoided.
Operational history
The first X-29 was taken aloft on 14 December 1984 from Edwards AFB with Grumman's Chief Test Pilot Chuck Sewell at the controls. With that flight, the X-29 became the second jet-powered aircraft to fly with forward swept wings (with the Nazi Germany-era Junkers Ju 287, which first flew in 1944, being the first)... The NASA test program continued from 1984 to 1991...

Russia's unique forward-swept wing jet trainer SR-10 is passing tests with the Russian Aerospace Forces in the Moscow Region.
The plane's name can be explained as "jet with wing sweep —10°", which reflects the aircraft's main constructional feature — the moderately forward-swept wings facilitating stability and maneuverability at low speeds.
This subsonic, single engine, all-composite plane meets the needs of unexperienced pilots who will later change it for the Yak-130 — a sophisticated trainer which is in fact a full-fledged combat plane wanted by a number of countries for their air forces.
