An alternative shape of strain-gauged balance for use in wind tunnels at low temperatures

The search for a shape of one-piece balance that might be more suitable than the conventional strain-gauged balance for general use in low-temperature wind tunnels, led to a design with symmetry in both the pitch and yaw planes and with most of the drag stiffness concentrated at ne axial location. Calculations of stress levels and deflection under load showed this design to have a performance similar to that of a modern conventional balance.
