A flap is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in drag so they are retracted when not … See more The general airplane lift equation demonstrates these relationships: $${\displaystyle L={\tfrac {1}{2}}\rho V^{2}SC_{L}}$$ where: • L … See more • Air brake (aeronautics) • Aircraft flight control system • Aileron • Body flaps, a type of high-drag set of aerosurfaces designed for very high angle-of-attack descent of rocket-powered vehicles, particularly used during atmospheric entry of space vehicles.

In aeronautics, the chord is an imaginary straight line joining the leading edge and trailing edge of an aerofoil. The chord length is the distance between the trailing edge and the point where the chord intersects the leading edge. The point on the leading edge used to define the chord may be the surface point of minimum radius. For a turbine aerofoil the chord may be defined by the line between po… WebFlap is a crossword puzzle clue that we have spotted over 20 times. There are related clues (shown below).

WebSep 28, 2024 · You have to think that your flap is a small wing by it's own. The fixation point of this wing, through which all loads must be transferred is at the leading edge. Then there is a moment created at this hinge by both the aerodynamic lift and the aerodynamic moment if your profile is not symmetrical. WebJan 6, 2024 · Chord Line. With your flaps retracted, your chord line is a straight line from the leading edge to the trailing edge of the wing. But when you lower your flaps, this chord line changes, altering the characteristics of your wing. With many flap designs (like slotted flaps ), when you lower your flaps, you'll see the wing expanding. porsche taycan interior 2021Webon the flap will be statically equivalent to a force N, normal to the chord and through the hinge axis, a tangential or chordwise force T and a hinge moment H. The force T is small and will at present be neglected but its influence on the hinge moment would not be negligible if the hinge axis had a large vertical offset from the chord line. irish filigree necklace pattern
