Available in PDF, EPUB and Kindle. Book excerpt: Strain-gauge balances for use in wind tunnels have been designed at Langley Research Center (LaRC) since its inception. Currently Langley has more than 300 balances available for its researchers. A force balance is inherently a critically stressed component due to the requirements of measurement sensitivity. The strain-gauge balances have been used in Langley s wind tunnels for a wide variety of aerodynamic tests, and the designs encompass a large array of sizes, loads, and environmental effects. There are six degrees of freedom that a balance has to measure. The balance s task to measure these six degrees of freedom has introduced challenging work in transducer development technology areas. As the emphasis increases on improving aerodynamic performance of all types of aircraft and spacecraft, the demand for improved balances is at the forefront. Force balance stress analysis and acceptance criteria are under review due to LaRC wind tunnel operational safety requirements. This paper presents some of the analyses and research done at LaRC that influence structural integrity of the balances. The analyses are helpful in understanding the overall behavior of existing balances and can be used in the design of new balances to enhance performance. Initially, a maximum load combination was used for a linear structural analysis. When nonlinear effects were encountered, the analysis was extended to include nonlinearities using MSC.Nastran . Because most of the balances are designed using Pro/Mechanica, it is desirable and efficient to use Pro/Mechanica for stress analysis. However, Pro/Mechanica is limited to linear analysis. Both Pro/Mechanica and MSC.Nastran are used for analyses in the present work. The structural integrity of balances and the possibility of modifying existing balances to enhance structural integrity are investigated.

This book was released on 1983 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: In multi-component strain gauge wind tunnel balances it is common practice to use four arm bridges of gauges arranged to produce an output from one load component and not from other load components which also cause significant strains under the gauges. This system relies on the fact that there is fundamentally one output-producing pattern of strains and three non-output-producing patterns. It is shown that interactions arise between the various strain patterns and that these interactions, and hence the balance calibration equations, are dependent on the nature of the readout equipment used. Specific precautions which must be observed to obtain 0.01% accuracy levels are investigated. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: DSTO operates a low speed wind tunnel within the Air Vehicles Division of the Platforms Sciences Laboratory. Air speeds up to approximately 90 m/s 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%.
