TsAGI participates in the 11th International Symposium on Strain-Gage Balances
Specialists of the Zhukovsky Central AeroHydrodynamic Institute (TsAGI) took part in the 11th International Symposium on Strain-Gage Balances, held in May in Cologne (Germany). In their reports TsAGI scientists covered issues of a six-component rotary balance calibration and studies of dynamic characteristics of strain-gage balances.

These devices are used in wind tunnels experiments, and special requirements are imposed on the precision of their indication. The measurement techniques and the balances themselves are ever-improving. That is why it is significant for specialists from different countries to have the opportunity and discuss improvement of balances designs and measurement methods, the use of computer modeling methods, 3D printing technologies when creating balances, experiments results, etc.

“The Symposium is the most important event dedicated to the development, calibration and operation of strain-gage balances,” said Vagan Manvelyan, TsAGI engineer of the Department Measuring technology and metrology, a participant in the Symposium. “It is a good opportunity for professionals to share experiences with the few colleagues who are so trained in the world. For example, we were able to get answers and clarify a new field of study for TsAGI — the rotary balance application. This will help us to improve the quality of our research.”

In addition, the Institute specialists participated in a panel discussion on the angle measurement in aeronautical experiments. The participants decided to arrange a section on this topic during the next Symposium in two years in South Africa.

The International Symposium on Strain Gage-Balances was an initiative of NASA. The first Symposium was organized in the USA in 1996. Its aim is to be an open international forum for presentation discussion and exchange of technical information among wind tunnel test technique specialists and strain gage balance designers. This year the event attended by more than 70 specialists from 40 industrial and scientific organizations of 15 countries in Europe, Asia, North and South America, Australia and Africa.
