To meet the demand of jet-effects test of large turbine fan aircraft

a kind of integrated jet-effects testing technique based on calibration tank was developed. The testing model and jet simulators were integrated according to the principle of the technique. Aerodynamic forces and thrust were both measured by wind tunnel balance. Thrust was calibrated in calibration tank and deducted from the testing data measured by wind tunnel balance. Techniques such as thrust calibration and deduction

air bridge

mass flow rate and nozzle pressure ratio controlling were introduced. In order to verify the reliability of integrated jet-effects testing technique

a thrust calibration test and a full model jet-effects wind tunnel test were conducted in the calibration tank and FL-13 low speed wind tunnel respectively. The test results indicated that

the calibration testing accuracy of thrust was better than 0.24%

and the repeatability testing accuracy of drag coefficient was 0.000 3

which can meet the accuracy need of jet-effects wind tunnel test.
