| Abstract: | In this paper,the design and calibration of a small two component strain-gauge balance used in wind tunnel test of propellers with power have been described and the main technical characteristics of this balance have been given. The check results show that the balance has high performance and precision.Now,it has been excellently used in wind tunnel tests for the design of aircraft propellers. |
