Use of accelerometers for measurement of pitch and bank angles in an aerodynamic experiment
Tóm tắt
Modern requirements imposed on the precision with which angles are measured are evaluated in an aerodynamic experiment. A method of calibration of an accelerometer with respect to two angular positions with estimation of the measurement error of the angles and a method of taking into account the influence of temperature on its readings are presented. It is shown that with the use of an A-17 accelerometer of the T-128 transonic wind tunnel of the Zhukovskii Central Aerohydrodynamic Institute it becomes possible to increase the measurement precision of the pitch angle of aircraft models several fold.
