Read full description

Shock Math is a fast, accurate compressible-aerodynamics calculator for students, engineers, and anyone working in high-speed gas dynamics. Solve isentropic, shock, and duct-flow relations in seconds β€” from any input variable, for any gas. COMPRESSIBLE FLOW, SOLVED β€’ Isentropic flow β€” pressure, temperature, density, and area ratios, Mach angle, and Prandtl–Meyer angle β€’ Normal shock relations β€” downstream Mach, static and stagnation pressure, temperature, and density ratios β€’ Oblique shock relations β€” weak and strong solutions, wave angle, deflection angle, and normal Mach components β€’ Conical shock relations β€” Taylor–Maccoll solution for cone angle, surface Mach number, and surface property ratios β€’ Fanno flow β€” adiabatic flow with friction in a constant-area duct β€’ Rayleigh flow β€” frictionless flow with heat addition β€’ Ideal gas law β€” p = ρRT and pV = nRT, with flexible units β€’ Scratch Pad β€” a quick built-in calculator for the numbers in between SOLVE FROM ANY VARIABLE Don't just go forward from Mach number. Enter a pressure ratio, temperature ratio, area ratio, wave angle, or Prandtl–Meyer angle and Shock Math finds the Mach number for you β€” subsonic or supersonic branch, your choice. ANY GAS, ANY GAMMA Set the ratio of specific heats (Ξ³) to model air, combustion products, monatomic gases, or anything in between. Every relation respects your Ξ³. PROVEN-ACCURATE MATH Version 1.6 rebuilt and independently verified the calculation engine. Every relation is cross-checked against the classic NACA Report 1135 tables and against independent reference implementations across a wide range of Mach numbers and specific-heat ratios β€” hundreds of checks, zero discrepancies. Forward and inverse solutions round-trip exactly. BUILT FOR REAL WORK β€’ Clean, focused calculators β€” no clutter β€’ Light and dark mode β€’ Show or hide the calculators you use β€’ Built-in reference notes explaining each set of relations β€’ Apple Watch scratch pad for quick calculations Whether you're checking homework in a gas dynamics course, sizing a supersonic nozzle, or sanity-checking a CFD result, Shock Math gives you trustworthy numbers fast. Feedback and feature requests are always welcome from the in-app form.
