The invention provides a system and method for measuring the torque of an aircraft in real time at moment of unfolding a control surface, and solves the problem that when the aircraft is subjected to a ground wind tunnel test, the existing torque measurement equipment cannot bear other external force loads except torsion, so that the torque measurement equipment is damaged or measurement data is wrong, and the flight state of the aircraft cannot be judged. The system comprises a fixing support, a supporting shaft, a bearing pair, a torque sensor, a linkage device and a measuring unit. The fixing support is located outside the tail of the aircraft and connected with the tail end of the supporting shaft. The supporting shaft is coaxially arranged in the aircraft projectile body through the bearing pair; the front end of the supporting shaft is coaxially and fixedly connected with the linkage device arranged in the aircraft projectile body through the torque sensor; the linkage device is coaxially and fixedly co
