Aspect ratio (aeronautics) An ASH 31 glider with very high aspect ratio (AR=33.5) and lift-to-drag ratio (L/D=56) In aeronautics, the aspect ratio of a wing is the ratio of its span to its mean chord. It is equal to the square of the wingspan divided by the wing area. Thus, a long, narrow wing has a high aspect ratio, whereas a short, wide wing ...
Class 1: Explosives. Division 1.1: Explosive that has a mass explosion hazard. A mass explosion is a detonation of almost entire load instantaneously. Division 1.2: Goods and Substances without a mass explosion hazard, but with a projection (shrapnel/fragmentation). Division 1.3: Goods and substances with a mass fire hazard, and a minor, blast ...
The 5,353 ton collier ship was 112.35 meters long, with a beam of 16.82 meters and a draft of 9.3 meters. She was powered by 3 boilers that powered one 3-cylinder triple expansion engine that powered a single shaft to a single screw with 462 nhp. During World War I, she served in the US Navy as the USS Fairmont.
The motion is a rapid pitching of the aircraft about the center of gravity, essentially an angle-of-attack variation. The short-period mode is an oscillation with a period of only a few seconds that is usually heavily damped by the existence of lifting surfaces far from the aircraft’s center of gravity, such as a horizontal tail or canard.
Heat 2 is a 2022 American crime novel written by Michael Mann and Meg Gardiner. Mann's debut novel , Heat 2 is both a prequel and a sequel to his 1995 crime film Heat [ 1 ] . It covers the formative years of homicide detective Vincent Hanna ( Al Pacino ) and criminals Neil McCauley (Robert De Niro ) and Chris Shiherlis ( Val Kilmer ).
A diagrammatic representation of a fixed-wing airplane in phugoid. In aviation, a phugoid or fugoid ( / ˈfjuːɡɔɪd / ⓘ) is an aircraft motion in which the vehicle pitches up and climbs, and then pitches down and descends, accompanied by speeding up and slowing down as it goes "downhill" and "uphill". This is one of the basic flight ...
This is a table of Clebsch–Gordan coefficients used for adding angular momentum values in quantum mechanics. The overall sign of the coefficients for each set of constant , , is arbitrary to some degree and has been fixed according to the Condon–Shortley and Wigner sign convention as discussed by Baird and Biedenharn.

ISO 3166-1 alpha-2 codes are two-letter country codes defined in ISO 3166-1, part of the ISO 3166 standard [ 1] published by the International Organization for Standardization (ISO), to represent countries, dependent territories, and special areas of geographical interest. They are the most widely used of the country codes published by ISO (the ...
