Balanced flow — In atmospheric science, balanced flow is an idealisation of atmospheric motion. The idealisation consists in considering the behaviour of one isolated parcel of air having constant density, its motion on a horizontal plane subject to selected… … Wikipedia
balanced control surface — i. A control surface that is aerodynamically balanced to reduce the force necessary to displace it by providing some area ahead of the hinge line. ii. A control surface balanced by weights ahead of its hinge line to reduce possible flutter … Aviation dictionary
Surface tension — For the work of fiction, see Surface Tension (short story). Surface tension is a property of the surface of a liquid that causes it to behave as an elastic sheet. It allows insects, such as the water strider (pond skater, UK), to walk on water.… … Wikipedia
Balanced field takeoff — In aviation, the balanced field takeoff is the theoretical principle whereby the critical engine failure recognition speed, or V1, is used as a decision speed at which the pilot elects whether to continue the takeoff. The concept at play is that … Wikipedia
balanced air force — The strength and composition of various elements of an air force in consonance with its overall mission, taking both the air and surface elements into consideration. A balanced force structure should provide for maximum flexibility, economy, and… … Aviation dictionary
Capillary surface — In fluid mechanics and mathematics, a capillary surface is a surface that represents the interface between two different fluids. As a consequence of being a surface, a capillary surface has no thickness in slight contrast with most real fluid… … Wikipedia
Level surface — Level Lev el (l[e^]v [e^]l), a. 1. Even; flat; having no part higher than another; having, or conforming to, the curvature which belongs to the undisturbed liquid parts of the earth s surface; as, a level field; level ground; the level surface of … The Collaborative International Dictionary of English
