Supersonic Mach Angle Calculator

Take the inverse sine of the reciprocal of a strictly supersonic Mach number. At Mach one the ideal limiting angle is 90 degrees, but this calculator requires a supersonic domain. It evaluates only the displayed equation and entered SI values; it does not infer material data or experimental conditions. Confirm the convention and inputs against the physical setup before using the result.

The result is the geometric characteristic angle of infinitesimal disturbances, not necessarily an observed finite shock angle. As Mach number rises, the ideal cone narrows. Display precision is not measurement accuracy. Check dimensions, scale, limiting cases, and input uncertainty against an independent source before using the value in laboratory, engineering, or safety-sensitive work.

The disturbance travels steadily through a uniform medium and the entered Mach number is greater than one using local sound speed. Finite-strength shocks, body geometry, acceleration, temperature gradients, refraction, viscosity, humidity, three-dimensional flow, and unsteady propagation are excluded. This educational result is not a simulation, calibration, design approval, or safety determination. Real systems may require measured properties, geometry, boundary conditions, uncertainty propagation, and numerical models beyond these inputs.
