drag angle
31feathering angle — The angular setting that gives a zero windmilling torque and, hence, minimum drag for a stopped propeller. Also called feathering pitch …
32Угол запаздывания — Drag angle Угол запаздывания. В сварке, угол между осью электрода или горелки и нормалью к плоскости сварки, когда сварка выполняется горелкой, расположенной перед сварочной ванной. (Источник: «Металлы и сплавы. Справочник.» Под редакцией Ю.П.… …
33Capacitance Electronic Disc — Capacitance Electronic Discs The CED, exposed from protective caddy Media type video playback media Capacity 60 minutes NTSC video per side, 27,000 frames per side[ …
34Сварка обратным способом — Backhand welding Сварка обратным способом. Техника сварки, при которой сварочная горелка или пушка направлена в сторону, обратную направлению сварки. Иногда упоминается «пушечная методика» в газовой дуговой сварке и сварке покрытым электродом.… …
35airplane — /air playn /, n. 1. a heavier than air aircraft kept aloft by the upward thrust exerted by the passing air on its fixed wings and driven by propellers, jet propulsion, etc. 2. any similar heavier than air aircraft, as a glider or helicopter. Also …
36Propeller — A propeller is essentially a type of fan which transmits power by converting rotational motion into thrust for propulsion of a vehicle such as an aircraft, ship, or submarine through a mass such as water or air, by rotating two or more twisted… …
37Atmospheric reentry — refers to the movement of human made or natural objects as they enter the atmosphere of a planet from outer space, in the case of Earth from an altitude above the edge of space. This article primarily addresses the process of controlled reentry… …
38Swept wing — A swept wing is a wing planform common on high speed aircraft, with the wing swept back instead of being set at right angles to the fuselage. This is a useful drag reducing measure for aircraft flying just below the speed of sound. Forward sweep… …
39Gravity turn — A gravity turn or zero lift turn is a maneuver (see trajectory optimization) used in launching a spacecraft into, or descending from, an orbit around a celestial body such as a planet or a moon. This launch trajectory offers two main advantages… …
40fluid mechanics — an applied science dealing with the basic principles of gaseous and liquid matter. Cf. fluid dynamics. [1940 45] * * * Study of the effects of forces and energy on liquids and gases. One branch of the field, hydrostatics, deals with fluids at… …
