subsonic airfoil
1Airfoil — An airfoil (in American English) or aerofoil (in British English) is the shape of a wing or blade (of a propeller, rotor or turbine) or sail as seen in cross section. An airfoil shaped body moved through a fluid produces a force perpendicular to… …
2Supercritical airfoil — it has since been mainly applied to increase the fuel efficiency of many high subsonic aircraft. Research in 1940 by DVL s K. A. Kawalki led to subsonic profiles very similar to the supercritical profiles, which was the basis for the objection in …
3airplane — /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 …
4military aircraft — Introduction any type of aircraft that has been adapted for military use. Aircraft have been a fundamental part of military power since the mid 20th century. Generally speaking, all military aircraft fall into one of the following… …
5Aerodynamics — is a branch of dynamics concerned with studying the motion of air, particularly when it interacts with a moving object. Aerodynamics is closely related to fluid dynamics and gas dynamics, with much theory shared between them. Aerodynamics is… …
6Mach number — (mathrm{Ma} or M) (generally pronEng|ˈmɑːk, sometimes IPA|/ˈmɑːx/ or IPA|/ˈmæk/) is the speed of an object moving through air, or any fluid substance, divided by the speed of sound as it is in that substance. It is commonly used to represent an… …
7Lift (force) — For other uses, see Lift. Boeing 747 8F landing A fluid flowing past the surface of a body exerts a surface force on it. Lift is the component of this force that is perpendicular to the …
8Shock wave — Bombshock redirects here. For the Transformers character, see Micromasters#Bombshock. For other uses, see shockwave. Schlieren photograph of an attached shock on a sharp nosed supersonic body. A shock wave (also called shock front or simply shock …
9Propeller — 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… …
10Gurney flap — The Gurney Flap (or wickerbill) is a small flat tab projecting from the trailing edge of a wing. Typically it is set at a right angle to the pressure side surface of the airfoil,cite journal author = Van Dam, C.P. coauthors = Yen, D.T.; Vijgen, P …
