اندازه گيري نيروهاي اعمالي به فرامين كنترل در آزمايشهاي پروازي هواپيما با استفاده از Strain Gauge

Measuring the Control exerting forces is one the important parameters in the flight tests. These forces must lie in the determined range of airplane design regulations like JAR and FAR. Airplane designers d manufacturers are always interest to introducing and implementing of appropriate and efficient methods of measuring forces. In this paper, a method to measure the Control exerting forces by strain gauge systems is presented. With this method, exerting forces will be measured easily in all flight tests, and the results are processed appropriately. Furthermore, repeatability and easiness of the method increases the exactness of the results and decreases the cost. This method was used successfully in glider and motoglider flight tests in Paravar Pars Corporation and the results were acceptable.
