Matthew Piers Watt Boulton (22 September 1820 – 30 June 1894), also published under the pseudonym M. P. W. Bolton, was a British classicist, elected member of the UK's Metaphysical Society, an amateur scientist and an inventor, best known for his invention of the aileron, a primary aeronautical flight control device.
The name "aileron", from French, meaning "little wing", also refers to the extremities of a bird's wings used to control their flight. [2] [3] It first appeared in print in the 7th edition of Cassell's French-English Dictionary of 1877, with its lead meaning of "small wing". [4] In the context of powered airplanes it appears in print about 1908.
Acrostic: a poem in which the first letter of each line spells out a word, name, or phrase when read vertically. Example: “A Boat beneath a Sunny Sky” by Lewis Carroll. Concrete (aka pattern): a written poem or verse whose lines are arranged as a shape/visual image, usually of the topic. Slam; Sound; Spoken-word; Verbless poetry: a poem ...
The roll is used to provide lateral displacement while maintaining the original heading. The maneuver begins like a normal barrel roll, but when the plane is nearly inverted, the pilot places the elevators and ailerons close to the neutral position. Called "unloading", this allows the inverted aircraft to fly momentarily in a fairly straight arc.
Note the aileron deflection on the right wing. Diagram of how an aileron roll is performed in relation to other common rolls. The aileron roll is an aerobatic maneuver in which an aircraft does a full 360° revolution about its longitudinal axis. When executed properly, there is no appreciable change in altitude and the aircraft exits the ...
Rigor is a cornerstone quality of mathematics, and can play an important role in preventing mathematics from degenerating into fallacies. well-behaved An object is well-behaved (in contrast with being Pathological ) if it satisfies certain prevailing regularity properties, or if it conforms to mathematical intuition (even though intuition can ...
The Wrights' pioneering use of "roll control" by twisting the wings to change wingtip angle in relation to the airstream led to the more practical use of ailerons by their imitators, such as Glenn Curtiss and Henri Farman. The Wrights' original concept of simultaneous coordinated roll and yaw control (rear rudder deflection), which they ...
Poetry (from the Greek word poiesis, "making") is a form of literary art that uses aesthetic and often rhythmic qualities of language to evoke meanings in addition to, or in place of, literal or surface-level meanings. Any particular instance of poetry is called a poem and is written by a poet.
