scientists use what is known as aMach Numberto represent the flow boundary past the local speed of sound. In other words, pushing past the sound barrier is defined as Mach 1. So how fast do you have to be going

known as the Darkstar. The test is designed to see if the new jet can reach Mach 10, although, Maverick (in keeping with his name) pushes the aircraft to Mach 10.2, causing the plane to disintegrate, forcing Maverick to call for help from an indiscriminate...
A turbofan is the turducken of engines -- essentially a turbojet wrapped in a larger cowling with a big fan slapped on its front. The fan pulls in more air, which the engine then splits into two streams: Some air moves through the nested turbojet, while the rest flows through the ...
Hypersonic Jet Planes Living on Air Taking Flight Hypersonic Military Technology Sources What Is Hypersonic Speed? Hypersonic speed is five times the speed of sound. Scientists measure speeds this fast with a Mach number, named for Austrian physicist Ernst Mach. Sound has a speed of Mach ...
How fast do jet engine turbines spin?RotationIt is necessary to measure rotation in some mechanical systems. The unit is RPM (revolutions per minute). It measures how many times a piece of equipment (such as a jet engine turbine) completes a full 360 degree rotation in a minute....
In the simplest type of jet engine, called a turbojet, air is drawn in at the front through an inlet (or intake), compressed by a fan, mixed with fuel and combusted, and then fired out as a hot, fast moving exhaust at the back....
Toothless, a character from 'How to Train Your Dragon', is the sole Night Fury seen in the series. His jet-black scales and physical traits represent the Night Fury species. His development was influenced by various animals, notably cats and black panthers, which inspired his fluid, mammalian...
If it’s just speed that you’re after, think again about how to study fast with this guide to high volume learning at speed.There are certainly ways to memorize long passages of text word-for-word that are 100% effective. There are people who are known to have done it. But, if ...
It's not the fastest fighter jet in the Air Force's arsenal — that title goes to the F-15E Strike Eagle – but it's up there. Just how fast it goes depends on its altitude, because a lower altitude comes with a higher level of drag while a higher one means less drag. At se...
