Algorithms for the Reduction of Wind-Tunnel Data Derived from Strain Gauge Force Balances.

Abstract

Algorithms and procedures are presented for the reduction of force and moment data derived from wind-tunnel models supported by internal strain-gauge balances. The algorithms are developed in their most general forms, suitable for implementation on the new generation of powerful minicomputers currently being included in wind-tunnel data acquisition systems. Although the emphasis of the report is on the treatment of data derived from sting mounted strain-gauge force balances, the analysis is applicable, with only minor modifications, to data derived from modern load-cell based external force balances. Keywords: Data reduction; Wind tunnel apparatus; Loads(forces); Moments. (Australia)
