Design of a six-component strain gauge balance for testing aircraft models in the hypersonic wind tunnel
Dragan Marinkovski Marija Samardžić
A six-component strain gauge balance is designed for the purpose of testing aircraft models in the hypersonic wind tunnel T–34 of the VTI VJ. Stress and strain analyses are presented, as well as the values of the output signals obtained from the measuring bridges. All the problems related to providing required test conditions and the ways of overcoming them are described.
Key words: wind tunnels, measuring equipment, strain gauge balance. |
