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 ...

When legendary pilot Chuck Yeager broke the sound barrier and flew the Bell X-1 past Mach 1 in 1947, it was the greatest aviation milestone ever achieved at that time. These days, however, reaching ...

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 ...

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 ...
