The continuous variable angle of attack force test in Φ0.5 meter hypersonic wind tunnel has large amount of data and high efficiency advantages. But affected by sensor response time differences, model self weight and model’s accelerate or decelerate, but the test data could not be processed without preprocess. The following work is mainly carried out: First, parameters of the model attack angle control system and the data acquisition system, and the software acquisition strategy are determined by testing. Then, the non delay digital filter is used to preprocess the experiment data, and the cross-correlation function is used to calculate the time delay of each component of the load balance relative to the angle of attack. Based on the regular force test data processing flow, And the correction methods of elastic angle, model self-weight, model centrifugal force and inertia force are put forward systematically. Finally, comparative verification test and balance temperature effect test was were carried out, it showed that the results of the continuous variable angle of attack test were in good agreement with the results of the conventional step test, the temperature effect at high Mach number could be reduced effectively by continuous variable angle of attack force test technical.
