AVIATION & AERONAUTIC CALCULATOR
Shock Wave Angle
A precise tool.
What is the Shock Wave Angle & How does it work?
The oblique shock wave angle is a critical parameter in the study of supersonic flow over surfaces, such as wings and nozzles. It describes the angle between the shock wave and the direction of the incoming flow.Understanding this relationship is essential for designing efficient and stable supersonic aircraft and engines.
sin(theta) = frac{2}{M^2 sin^2(beta) – 1}
theta = oblique shock wave angle, M = Mach number, beta = deflection angle

Frequently Asked Questions
What is an oblique shock wave?
An oblique shock wave is a type of shock wave that occurs at an angle to the direction of the incoming flow, common in supersonic aerodynamics.
How do I calculate the Mach number for my aircraft?
The Mach number is calculated by dividing the speed of the aircraft by the speed of sound in the surrounding air.
What is the deflection angle in this context?
The deflection angle, Ξ², is the angle between the incident flow direction and the normal to the shock wave front.
Why is understanding the oblique shock wave angle important?
Understanding it is crucial for designing efficient and stable supersonic aircraft and engines that can handle high-speed airflow effectively.
Can this calculator be used for subsonic flow?
No, this calculator specifically deals with supersonic flow. For subsonic flow, different principles and equations apply.
What happens if the Mach number is less than 1?
If the Mach number is less than 1, the flow is subsonic, and oblique shock waves do not occur; instead, there might be a normal shock or other types of flow separation.
How does changing the deflection angle affect the shock wave angle?
Changing the deflection angle affects the sine of the shock wave angle according to the given formula, impacting the overall aerodynamic behavior of the aircraft.
