Pocket wind tunnel

Feel the air flow over a wing — in your hand.

Kivoraq runs a real-time aerodynamics sandbox on your phone. Shape a section, sweep the angle of attack, and watch streamlines stay attached — or separate into stall.

What's inside

A simulator, not a slideshow.

Every screen is live. Drag a slider and the physics recompute — lift, drag, pressure field and flow separation, all at once.

Wind tunnel

Watch the flow decide.

Switch between Streamlines, Pressure and Velocity views. Push the angle of attack and wind speed until the section stalls.

  • Angle of attack 6.0°, wind speed 22.0 m/s — live Cl & Cd
  • Streamlines · Pressure · Velocity overlays
  • Tracers toggle to seed particles into the flow

Shaper

Sculpt your own section.

Drag thickness and camber and the profile redraws instantly. A validity meter warns you when the geometry reaches the edge of what flies.

  • Thickness and camber ratio sliders
  • Live section summary & zero-lift angle
  • Save shapes straight into your gallery

Polar & Learn

Read the whole envelope.

Sweep the full range and see the drag polar, the lift curve and a numbered sweep table — then tap into the Learn cards to understand why.

  • Drag polar colour-coded by flow state
  • Lift curve with the stall break visible
  • Sweep table from −15° through stall
