A The Relationship Between The Change Of Flow Direction De And Velocity Perturbation Dv From Speed Vacross A Mach Wave 2 (50.13 KiB) Viewed 37 times
a) The relationship between the change of flow direction de and velocity perturbation dV from speed Vacross a Mach wave in a supersonic flow at Mach number M is given by dV V dᎾ M2 - 1 Consider a thin, symmetric aerofoil with chord length c of negligible thickness at angle of attack a to a supersonic free stream of Mach number Moo.

Cd + M2 where S, and are the slopes of the upper and lower surfaces relative to the chord line and s is the ordinate along the chord line. VPE-1 2-1 [ 03 + S (83 +87) 1161
