Camber (aerodynamics) In aeronautics and aeronautical engineering, camber is the asymmetry between the two acting surfaces of an airfoil, with the top surface of a wing (or correspondingly the front surface of a propeller blade) commonly being more convex (positive camber). An airfoil that is not cambered is called a symmetric airfoil.
Wingnut (hardware) A wingnut, wing nut or butterfly nut is a type of nut with two large metal "wings", one on each side, so it can be easily tightened and loosened by hand without tools. A similar fastener with a male thread is known as a wing screw[1][2] or a wing bolt. [3]
Fixed-wing aircraft. A Boeing 737 airliner is an example of a fixed-wing aircraft. The fixed wings of a delta -shaped kite are not rigid. A fixed-wing aircraft is a heavier-than-air aircraft, such as an airplane, which is capable of flight using aerodynamic lift. Fixed-wing aircraft are distinct from rotary-wing aircraft (in which a rotor ...
An airplane (North American English) or aeroplane (British English), informally plane, is a fixed-wing aircraft that is propelled forward by thrust from a jet engine, propeller, or rocket engine. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, transportation of ...
An airship[a] is a type of aerostat or lighter-than-air aircraft that can navigate through the air flying under its own power. [1] Aerostats use buoyancy from a lifting gas that is less dense than the surrounding air to achieve the lift needed to stay airborne.
Wrench. A set of metric spanners or wrenches, open at one end and box/ring at the other. These are commonly known as “combination” spanners. A wrench or spanner is a tool used to provide grip and mechanical advantage in applying torque to turn objects—usually rotary fasteners, such as nuts and bolts —or keep them from turning.
Cantilever wings require much stronger and heavier spars than would otherwise be needed in a wire-braced design. However, as the speed of the aircraft increases, the drag of the bracing increases sharply, while the wing structure must be strengthened, typically by increasing the strength of the spars and the thickness of the skinning.
Definitions and etymology. According to Merriam-Webster, a "wingnut" is "a mentally deranged person" or "one who advocates extreme measures or changes: radical". [1] Lexico, an online dictionary whose content comes from Oxford University Press, gives the political definition of "wing nut" as "A person with extreme, typically right-wing, views."
