supersonic speed
In fluid dynamics, the Mach number (M or Ma) is a dimensionless quantity representing the ratio ... While the terms subsonic and supersonic, in the purest sense, refer to speeds below and above the local speed of sound respectively, ... ,The sound barrier or sonic barrier is the sudden increase in aerodynamic drag and other undesirable effects experienced by an aircraft or other object when it approaches the speed of sound. When aircraft first began to be able to reach close to the speed ,A supersonic aircraft is an aircraft able to fly faster than the speed of sound (Mach number 1). Supersonic aircraft were developed in the second half of the ... ,The flow pattern at supersonic speed shown in Fig. 42 is similar to that of subsonic speed [3]. At supersonic speeds the characteristics of cavity flow are as ... ,Supersonic travel is a rate of travel of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea ... , A bullet fired from a gun travels at supersonic speeds. This picture shows a bullet and the air flowing around it.
