Abstract:

DSTO operates a low speed wind tunnel within the Air Vehicles Division of the Platforms Sciences Laboratory. Air speeds up to approximately 90 ms can be produced in the test section which is 2.7 m wide by 2.1 m high. A six-component Collins internal strain-gauge balance is used to measure forces and moments on a model under test. A manual calibration of this balance has been carried out to determine the sensitivity matrix for the new amplifiers and wiring system integrated into the low speed wind tunnel data acquisition system following its upgrade in 2000. With the new sensitivity matrix the maximum standard error of the loads measured by the strain-gauge balance was 0.19.
