What is the meaning of hypersonic flight?

Hypersonic flight is flight through the atmosphere below about 90km at speeds above Mach 5, a speed where dissociation of air begins to become significant and high heat loads exist.

Furthermore, what is the speed of hypersonic?

A proposed hypersonic plane, dubbed Skreemr, could fly passengers from New York to London in just 30 minutes, traveling at 10 times the speed of sound, or just under 8,000 mph (12,348 km/h).

How fast is hypersonic speed in mph?

Such nozzles are called de Laval nozzles and in extreme cases they are able to reach hypersonic speeds (Mach 13 (15,926 km/h; 9,896 mph) at 20 °C). An aircraft Machmeter or electronic flight information system (EFIS) can display Mach number derived from stagnation pressure (pitot tube) and static pressure.

What is meant by supersonic flow?

Mach number, wave motion, and sonic speed. The Mach number (M) is defined as the ratio of the speed of an object (or of a flow) to the speed of sound. These regimes are subsonic, transonic, supersonic, hypersonic, and hypervelocity flow.

What is the purpose of chest tube water seal?

The middle chamber of a traditional chest drainage system is the water seal . The main purpose of the water seal is to allow air to exit from the pleural space on exhalation and prevent air from entering the pleural cavity or mediastinum on inhalation.
