In aerodynamics, hypersonic speeds are speeds that are highly supersonic. In the 1970s the term generally came to refer to speeds of Mach 5 and above.

Supersonic airflow is decidedly different than subsonic flow. Practically everything about the way an aircraft flies changes dramatically as an aircraft accelerates to supersonic speeds. Even with this strong demarcation, there is still some debate as to the definition of "supersonic". One definition is that the aircraft, as a whole, is travelling at Mach 1 or greater. More technical definitions state that you are only supersonic if the airflow over the entire aircraft is supersonic, which occurs around Mach 1.2 on typical designs. From Mach 0.8-1.2 is therefore considered transonic.

Hypersonic (laptop): Hypersonic is a company selling mainly desktop replacement laptops under the brand name Aviator. These laptops use many desktop components and as such can turn out quite large. They also sell Gaming desktops and workstations....

Aerodynamics: Aerodynamics is a branch of fluid dynamics concerned with the study of gas flows, first analysed by George Cayley in the 1800s. The solution of an aerodynamic problem normally involves calculating for various properties of the flow, such as velocity, pressure, density, and temperature, as a functio...
