Why did F-14 have swing wings?

which is why the Navy’s fleet defense fighter of the 1960’s was the F-4 Phantom II was a mach 2 fighter. So they used an advanced flight control computer which would move the f-14’s wings automatically to configure it for the optimum sweep for the necessary speed, altitude and angle of attack.

Why are there no swept wing aircraft?

However, the most important reason for variable sweep wings falling out of favor is that they are nearly impossible to be made stealthy. One way to make the aircraft stealthy is to reflect the Radar energy away from the source. In order to achieve this, the wings of stealth aircraft are designed in a specific way.

What is the purpose of swing wing aircraft?

A variable-sweep wing, colloquially known as a “swing wing”, is an airplane wing, or set of wings, that may be swept back and then returned to its original straight position during flight. It allows the aircraft’s shape to be modified in flight, and is therefore an example of a variable-geometry aircraft.

What is the point of swept wings?

Swept wings, however, are designed to reduce turbulence by slowing down the air as it moves across the surface of the wings. As previously mentioned, swept wings are longer than straight wings. Therefore, air moves more slowly across them, which reduces the amount of turbulence the airplane encounters.

Why don’t we use the swing mechanism in modern planes?

The swing mechanism takes up too much space inside the wing that could be used for fuel. It is difficult to position hard-points in the swinging part of the wing, affecting payload. Advances in aerodynamics and better engines mean that the drag reduction using varying the wing sweep is not so critical anymore.

What was the last military aircraft with a variable-sweep wing?

The last variable-sweep wing military aircraft to date was the Soviet Tupolev Tu-160 “Blackjack” strategic bomber, which first flew in 1980. A variable-sweep wing was also selected as the winning design used by Boeing’s entry in the FAA’s study for a supersonic transport, the 2707.

Why are variable wing designs unjustifiable for phases of flight?

So in conclusion; the emergence of reliable fly-by-wire systems made the heavy and complicated variable wing designs unjustifiable for phases of flight they were meant to improve, because FBW is much cheaper and delivers higher performance. An extreme example of a high angle of attack, level flight.

What is the advantage of variable wing over sweep wing?

See, the reason variable wing is utilised in an aircraft design is to make it perform well on different flight envelopes, mainly slow speed and high speed handling. Swept wing is good for high speed work but perform poorly at low speeds and vice versa.
