1. supersonicadjective

   Moving at a speed greater than the speed of sound in air; -- this speed varies with altitude, since the speed of sound varies with altitude, as well as with temperature and humidity, being approximately 1129 feet per second at sea level and 984 feet per second at 16 miles altitude.

2. supersonicadjective

   Capable of moving at speeds higher than the speed of sound; -- of aircraft.

1. Supersonic

   Supersonic speed is the speed 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 level, this speed is approximately 343.2 m/s (1,126 ft/s; 768 mph; 667.1 kn; 1,236 km/h). Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.2. Sounds are traveling vibrations in the form of pressure waves in an elastic medium. Objects move at supersonic speed when the objects move faster than the speed at which sound propagates through the medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, the speed of sound, and Mach numbers for a steadily moving object may change. In water at room temperature supersonic speed can be considered as any speed greater than 1,440 m/s (4,724 ft/s). In solids, sound waves can be polarized longitudinally or transversely and have even higher velocities. Supersonic fracture is crack motion faster than the speed of sound in a brittle material.

Examples of supersonic in a Sentence

1. George Abbey:

   If I could fly supersonic transport, I could reduce that [travel] time, time is really money, and spending a short time on an airplane vs. a long time, I’d prefer taking the short time.

2. Jonny Kim:

   Single cracks are usually not good. The crack, you know, in the crack, when I say crack, I mean when you are on the giving end of a rifle, you it's a much different sound than being on the receiving end of a rifle, that of a bullet that is supersonic makes a very distinctive crack. And when you hear that, and it's a single one, it generally is not good.

3. Daniel Edgington-Mitchell:

   Even if you built something new, I think you are going to be struggling, i think that is why there is such a push in the United States to reconsider the standards particularly for supersonic aircraft because it is just going to be really difficult.

4. Ed Stone:

   This has really been a wonderful journey that began with the launch of two spacecraft in 1977 to explore Jupiter and Saturn, our journey has expanded deeper and deeper into space. We had no quantitative idea of how big this bubble is that the sun creates around itself with its supersonic solar wind, made of ionized plasma, which is speeding away from the sun in all directions. And we didn't know the spacecraft could live long enough to reach the edge of the bubble, leave it and enter nearby interstellar space.

5. Elon Musk:

   These things are much more important than creating electric supersonic VTOL.
