    2021-8-2 · Air-jet spinning is also known as Vortex or fasciated yarn spinning. It was introduced in the 1980s. A basic air-jet spinning system is shown in Figure 9.12.Before the sliver from the drawframe is supplied to the air-jet spinner, combing is often used, as it is imperative to get rid of any dust or trash that could obstruct the spinning jets.

A very simple rule of thumb is that the throw (the distance for a jet to reach a stated ’terminal velocity’) of at an air jet to a terminal velocity of 75 fpm is effected by about 1% degree F delta-t. A downward jet of cold air will travel further, hot air less, than isothermal air.

    2019-1-16 · “Lift” Keeps the Airplane Up. Although aerodynamics is a very complicated topic, one simplistic statement sums up the basic principle of flight: An airplane stays up because its wings push the air down. [] This is called “lift.” An airplane generates lift, however, only when it is moving. This is completely different than a lighter-than-air balloon.
