X-wings with their s-foils locked in attack position as they assault the Death Star in Star Wars (1997 Special Edition). The T-65B X-wing was produced by the Incom Corporation, which had previously supplied the ARC-170 and Z-95 Headhunter starfighters to the Galactic Republic during the Clone Wars.
After World War II, NACA research began to focus on near-sonic and low-supersonic airflow.After considering the sudden drag increase which a wing-fuselage combination experiences at somewhere around 500 mph (800 km/h), Whitcomb concluded that "the disturbances and shock waves are simply a function of the longitudinal variation of the cross-sectional area" – that is, the effect of the wings ...
Camber is usually designed into an airfoil to raise its maximum lift coefficient C Lmax.This minimizes the stalling speed of aircraft using the airfoil. An aircraft with wings using a cambered airfoil will have a lower stalling speed than an aircraft with a similar wing loading and wings using a symmetric airfoil.
In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack exceeds its critical value. [1] The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid , foil – including its shape, size, and finish – and Reynolds number .
Hydrofoiling wingsail catamaran 17. A sailing hydrofoil, hydrofoil sailboat, or hydrosail is a sailboat with wing-like foils mounted under the hull.As the craft increases its speed the hydrofoils lift the hull up and out of the water, greatly reducing wetted area, resulting in decreased drag and increased speed.
The S-72 in flight without a main rotor in 1984. Sikorsky and Bell Helicopters competed for the RSRA contract. [1] Bell's preferred proposal was the "Bell 646A" with rotors based on the Bell 240 UTTAS; the alternative was the smaller "Bell 646B" based on the Bell 309 KingCobra. [2]
For example, the dihedral angle is usually greater on low-wing aircraft than on otherwise-similar high-wing aircraft. This is because "highness" of a wing (or "lowness" of vertical center of gravity compared to the wing) naturally creates more dihedral effect itself. This makes it so less dihedral angle is needed to get the amount of dihedral ...
The X-wing starfighter, named for the distinctive shape made when its S-Foils are in attack position, was a class of starfighter used by the Rebel Alliance in their conflict with the Galactic Empire. It made its theatrical debut, as the T-65B model, in Star Wars (1977) as the spacecraft piloted by Luke Skywalker and the Red Squadron when Luke ...
