Also known as the jet sweep or fly sweep, [6] this sweep is a running play that is run from a set with a wide receiver (flanker) split out to the side away from the play, often run with the receiver in motion. The quarterback receives the snap and turns or runs toward the receiver, as the receiver makes a deep arc into the backfield behind the ...
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.
End-around is a type of special run play in football. [7] Whereas in the end around the receiver crosses the backfield after the snap, in the jet sweep, the receiver goes in motion and the quarterback calls for the snap just as the receiver passes him. [8]
A variable-sweep wing, colloquially known as a "swing wing", is an airplane wing, or set of wings, that may be modified during flight, swept back and then returned to its previous straight position. Because it allows the aircraft's shape to be changed, it is a feature of a variable-geometry aircraft.
Full-scale prototype design of a flying test single-seat jet fighter with a wingspan of 8.06 m and a length of 8.98 m. It had a conventional tail and swept wings designed to be set at different angles while on the ground. Test flights were first intended to be undertaken with a 35-degree wing sweep, followed by a 45-degree sweep.
A composite photograph showing the Bell X-5’s variable-sweep wing. The Bell X-5 was the first aircraft capable of changing the sweep of its wings in flight. It was inspired by the untested wartime P.1101 design of the German Messerschmitt company. In a further development of the German design, which could only have its wing sweepback angle ...
The Junkers Ju 287 was a multi-engine tactical jet bomber built in Nazi Germany in 1944. It featured a novel forward-swept wing, and the first two prototypes (which were aerodynamic testbeds for the production Ju 287) were among the very few jet propelled aircraft ever built with fixed landing gear.
Meanwhile in Germany, Hans Wocke was studying the problems of swept wings at the near-sonic speeds of which the new jet engines were capable. He recognised many of the advantages that forward sweep offered over the backwards-swept designs then being developed, and also understood the implications of aeroelastic bending and yaw instability.
