The Mach number fields … In aerodynamics, the critical Mach number (Mcr or M*) of an aircraft is the lowest Mach number at which the airflow over some point of the aircraft reaches the speed of sound, but does not exceed it. At the lower critical Mach number, airflow around the entire aircraft is subsonic. Supersonic aircraft such as Concorde and combat aircraft also have an upper critical Mach number at whi…

Discussion WebAbstract. Optimum critical nonlifting airfoils that have the highest free stream Mach number M. for a given thickness ratio 8 have recently been presented by Schwendeman, Kropinski, and Cole [Z. Angew. Math. Phys., 44 (1993), pp. 556-571]. The asymptotic shape of these airfoils as Mo. -o 1 and 8 -O 0 consists of a sonic arc with a (x2/5) nose.
