Unlike civil aviation, where aircraft fly relatively steadily and generate lift at low angles of attack, military aircraft are often required to perform extreme manoeuvres. These manoeuvres can push ...

Perhaps the only undesirable characteristic of the Mach number is that it is not directly indicative of the local flow velocity. This is true in the sense that the sonic speed itself is a function of ...

In order to push flight technology beyond the supersonic regime, fundamental research on viscous hypersonic flow will be essential. It is widely recognized that this research must have both a strong ...

“Mach 1”: The term refers to the speed of sound, which is not a fixed number but varies based on the temperature of the surrounding gas. Named for Austrian physicist Ernst Mach, the term is a little ...

Rearranging terms, and recalling the definition of the Mach number (3.17), the following expression can easily be obtained: Equations (3.20) through (3.22) are better viewed as simply relating the ...
