The invention belongs to the technical field of aviation and particularly relates to an aircraft actuation system load loading device applicable to an aircraft actuation system loading project. According to the device, a single-actuator loading device and an aircraft airfoil loading device are improved, double effects of applying one device to single-actuator performance parameter index evaluation and aircraft airfoil actuator joint loading are realized, and a novel loading device is provided for the aircraft actuation system. The loading device provided by the invention is simple and convenient, and meets two loading needs for top loading and airfoil loading in the field of aircraft actuation system load loading through a connecting mechanism, a slider mechanism and a bracket mechanism. The resources are saved; and two processes in the aircraft loading project are realized by one mechanism, thus the equipment resources as well as the space resources of a laboratory are saved. The workflow is accelerated; and through the technical scheme, the time period of original two processes can be effectively shortened, and the process of applying an actuator to the aircraft airfoil is accelerated.
