The prefix Mach is used to describe supersonic speed.It was named for Ernst Mach(1838-1916),a Czech-born Austrian physicist,who contributed to the study of sound.When twice the speed of sound,it is Mach 2.When it is near but below the speed of sound,its speed can be designated at le...
NASA released images of the first ever air-to-air images of supersonic shockwaves, part of a study that seeks to make supersonic aviation quieter.
In the end, diffused flow 18 will be slow enough, about 700 feet per second (“FPS”), to enter axial flow compressor 4 in normal fashion. Thus, the events in FIG. 2 are similar to what happens in the nacelles of the Concorde airliner at Mach 2, and axial flow compressor 4 could...
The speed of sound is generally placed at 1088 feet per second at sea level at 32 degrees Fahrenheit. It varies in other temperatures and in different media. Sound travels faster in water than in air, and even faster in iron and steel. It travels a mile in 5 seconds in air, it does...
flight path, the company says it plans to fly its passenger aircraft at supersonic speeds over the ocean, and will fly at just below the speed of sound when over land. That's still significantly faster than the cruising speed of traditional jetliners, however, which is about 550 to 600 ...
The authors tested whether their model tail would be able to withstand the stress of moving fast enough to create a supersonic boom. They found that the thin whip-like tail could not move at a maximum speed of 340 meters per second (1100 feet per second) without breaking. ...
The Hoka Mach Supersonic is a speed trainer best suited to tempo runs and speed workouts. Its new ProFly+ midsole foam makes it firmer and easier to pick up the pace but also makes it less enjoyable for easy runs. The version is slightly heavier than its
conventional commercial airliner. In many ways, the interior was like that of a spaceship, with only 25 rows of seats set two on either side of the aisle and tiny widows that only added to the impression. Up front was a large digital display showing the altitude in feet and the speed ...

Recently, a number of tools have been marketed that claim to produce a superior air stream for improved digging purposes by employing a means to make the air exit the tool at a supersonic speed. Little attention has been paid to the proper engineering design of these nozzles for the purpose...
