How do I simulate a wind-tunnel airfoil?

Open this page and use the live Standard Atmosphere tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive a wind-tunnel airfoil from your own measurements.

The International Standard Atmosphere is the reference model all aircraft and instruments are calibrated against. Temperature falls steadily through the troposphere at 6.5 °C/km, then holds constant in the stratosphere above the tropopause. Pressure and density decay roughly exponentially — at airliner altitude the air is only a quarter as dense as at sea level.

Governing equation

T = T_{0} - L h = 288.15 - 0.0065 \cdot 10000 = 223.1 K, p = p_{0} (\frac{T}{T _{0}})^{g / (L R)} = 26.4 kPa

Reading this result: Below the 11 km tropopause, temperature falls at 6.5 °C/km — here it is -50 °C and the air holds 34% of sea-level density.

About this simulation

The full Standard Atmosphere tool models a wind-tunnel airfoil 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.
