Steady flight, unaccelerated flight, or equilibrium flight is a special case in flight dynamics where the aircraft's linear and angular velocity are constant in a body-fixed reference frame. [1] Basic aircraft maneuvers such as level flight, climbs and descents, and coordinated turns can be modeled as steady flight maneuvers. [ 2 ]
One technical definition is that a kite is “a collection of tether-coupled wing sets“. [119] The name derives from its resemblance to a hovering bird. [120] Kutta condition – is a principle in steady-flow fluid dynamics, especially aerodynamics, that is applicable to solid bodies with sharp corners, such as the trailing edges of airfoils.
TV-broadcaster slang for a shot in which there is no favorable outcome possible. Dimples The round indentations on a golf ball cover which are scientifically designed to enable the ball to make a steady and true flight. Dimples, by reducing drag, allow a golf ball to stay in the air for a longer flight than would be possible with a smooth ball ...
While slang is usually inappropriate for formal settings, this assortment includes well-known expressions from that time, with some still in use today, e.g., blind date, cutie-pie, freebie, and take the ball and run. [2] These items were gathered from published sources documenting 1920s slang, including books, PDFs, and websites.
A flight attendant revealed the secret meaning behind the airplane chime sounds you hear during a flight.
Most aircraft trimmed for straight-and-level flight, if flown stick-fixed, will eventually develop a tightening spiral-dive. [2] If a spiral dive is entered unintentionally, the result can be fatal. A spiral dive is not a spin; it starts, not with a stall or from torque, but with a random perturbation, increasing roll and airspeed.
In honor of Black Twitter's contribution, Stacker compiled a list of 20 slang words it brought to popularity, using the AAVE Glossary, Urban Dictionary, Know Your Meme, and other internet ...
After the flight, data were transcribed from the records and the results were correlated with pilot opinion. This approach would be considered routine today, but it was a notable original contribution by Gilruth that took advantage of the flight recording instruments already available at Langley and the variety of airplanes available for tests ...
