ABSTRACTDSTO operates a low speed wind tunnel within <strong>the</strong> Air Vehicles Division <strong>of</strong> <strong>the</strong> Plat<strong>for</strong>ms Sciences Laboratory.Air speeds up to approximately 90 m/s can be produced in <strong>the</strong> test section which is 2.7 m wide by 2.1 m high.A six-component <strong>Collins</strong> internal strain-gauge balance is used to measure <strong>for</strong>ces and moments on a modelunder test. A manual calibration <strong>of</strong> this balance has been carried out to determine <strong>the</strong> sensitivity matrix <strong>for</strong> <strong>the</strong>new amplifiers and wiring system integrated into <strong>the</strong> low speed wind tunnel data acquisition system followingits upgrade in 2000. With <strong>the</strong> new sensitivity matrix <strong>the</strong> maximum standard error <strong>of</strong> <strong>the</strong> loads measured by <strong>the</strong>strain-gauge balance was 0.19%.Page classification: UNCLASSIFIED
