Sting Balance

About Sting Balance

Overview

High-precision internal force and moment balances engineered for subsonic, transonic, and supersonic wind tunnel testing. Machined from a single piece of precipitation-hardened stainless steel, these balances deliver exceptional strength, accuracy, and minimal cross-interference, making them ideal for advanced aerodynamic research.

Designed to fit inside test models, internal balances provide direct measurement of aerodynamic loads while maintaining clean external flow conditions.
