Mach number

Below the speed of sound, pressure waves race ahead of an aircraft. At and above Mach 1 the aircraft outruns its own sound, and the waves pile into a cone-shaped shock — the sonic boom. The faster it flies, the more sharply swept the Mach cone: its half-angle is arcsin(1/M). This geometry governs supersonic and hypersonic vehicle design.

Governing equation

μ = arcsin \frac{1}{M} = arcsin \frac{a}{v} = arcsin \frac{1}{2.0} = 30. 0^{\circ}

Reading this result: At Mach 2.0 the half-angle is arcsin(1/M) = 30.0° — faster flight sweeps the Mach cone tighter around the flight path.

About this simulation

The full Mach Cone tool models a helicopter rotor with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
