To deal with the aerodynamic characteristics at such speed, supersonic airfoils are required on the aircraft. However, when the object moves at such a high speed, shock waves are formed, which can alter the aerodynamics of the aircraft. The shock wave is a result of fluid ...
WebJul 10, 2024 · The first and foremost factor for the shock angle is speed. Mach 1 will cause a straight shock and higher speeds will bend the shock backwards into an oblique shock with a shock angle φ according to the equation. φ = a r c c o s ( 1 M a) This angle will become smaller with increasing bluntness of the body causing it.
