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.
Time published an April 2, 1973 article, The Paper-Plane Caper, [2] about the paper airplane and its Kline–Fogleman airfoil. Also in 1973, CBS 60 Minutes did a 15-minute segment on the KF airfoil. CBS reran the show in 1976. [citation needed] In 1985, Kline wrote a book entitled The Ultimate Paper Airplane. [3]
Supercritical airfoils feature four main benefits: they have a higher drag-divergence Mach number, [21] they develop shock waves farther aft than traditional airfoils, [22] they greatly reduce shock-induced boundary layer separation, and their geometry allows more efficient wing design (e.g., a thicker wing and/or reduced wing sweep, each of which may allow a lighter wing).
Years of research and experience with the unusual conditions of supersonic flow have led to some interesting conclusions about airfoil design. Considering a rectangular wing, the pressure at a point P with coordinates (x,y) on the wing is defined only by the pressure disturbances originated at points within the upstream Mach cone emanating from point P. [3] As result, the wing tips modify the ...
In another comparison with the Camel, a very large but streamlined aircraft such as the Lockheed Constellation has a considerably smaller zero-lift drag coefficient (0.0211 vs. 0.0378) in spite of having a much larger drag area (34.82 ft 2 vs. 8.73 ft 2). Furthermore, an aircraft's maximum speed is proportional to the cube root of the ratio of ...
The weight a foil can lift is proportional to its lift coefficient, the density of the fluid, the foil area and its speed squared. The following shows the lifting ability of a flat plate with span 10 metres and area 10 square metres moving at a speed of 10 m/s at different altitudes and water depths.
The final day of SailGP's Season 4 could bring a nice seven-figure payday for skipper Peter Burling and his Team New Zealand Black Foils on San Francisco Bay. The Kiwis head into the final regatta ...
The distribution of forces on a wing in flight are both complex and varying. This image shows the forces for two typical airfoils, a symmetrical design on the left, and an asymmetrical design more typical of low-speed designs on the right. This diagram shows only the lift components; the similar drag considerations are not illustrated.
