🔑 Why Use Load Cells in Wind Tunnels?

Wind tunnels replicate real-world aerodynamic conditions at controlled scales. Load cells are essential because they:

• ✅ Measure lift, drag, thrust, and side forces.

• ✅ Enable multi-axis force and moment measurement (6-component balances).

• ✅ Provide high sensitivity for low-force model testing.

• ✅ Ensure repeatability and accuracy under varying wind speeds.

• ✅ Support both educational experiments and industry-grade aerospace R&D.
