leading edge of the airfoil
31root chord — The chord of an airfoil measured from its leading edge to the trailing edge at its root. In an airfoil that has no sweepback at all, the value of the root chord is equal to the normal chord. See mean chord …
32GWS Slow Stick — The Slow Stick radio controlled model plane is a basic, electrically powered, trainer park flyer that can be flown in relatively small spaces such as parks which permit RC aircraft.It is popular with beginner or novice RC plane pilots due to its… …
33chord length — The length of a chord. The straight line distance from the leading edge to the trailing edge of an airfoil …
34center-of-pressure coefficient — The ratio of the distance of the center of pressure from the leading edge of an airfoil to its chord length …
35Lift (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 …
36airplane — /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 …
37Insect wing — Original veins and wing posture of a dragonfly. Hoverflies hovering to mate …
38Stall (flight) — For other uses, see stall. In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases. This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is… …
39fluid 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… …
40Paragliding — is a recreational and competitive flying sport. A paraglider is a free flying, foot launched aircraft. The pilot sits in a harness suspended below a fabric wing, whose shape is formed by the pressure of air entering vents in the front of the wing …
