Governing equation

Reading this result: Near-zero viscosity: momentum barely dissipates, so vortices persist and the flow tips into turbulent, chaotic mixing.

Mach Cone & Sonic BoomLive

Controls

Presets

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.

Cone half-angle30.0°

Governing equation

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.

Controls

The equation that rules spaceflight. Your Δv budget depends only on exhaust velocity and the ratio of full-to-empty mass — and it's brutally logarithmic.

Δv5524 m/s
Mass ratio5.00
Propellant400 t
Exhaust vel.3432 m/s

Governing equation

Reading this result: At 5524 m/s this stage cannot reach orbit; since Δv grows only with the log of mass ratio, big gains need a much emptier tank or higher Isp.
