The invention provides a pneumatic wing loading device, which belongs to the technical field of wing strength tests. The pneumatic wing loading device provided by the invention is designed to solve problems that it is complicated in operation by using a hydraulic system to apply a load to a wing and the hydraulic system is not portable. The pneumatic wing loading device comprises an air pump, an electromagnetic proportional valve, a multi-way pipe joint, n electromagnetic valves, n cylinders and a control part, wherein an air outlet of the air pump is communicated with an air inlet of the electromagnetic proportional valve; an air outlet of the electromagnetic proportional valve is communicated with an air inlet of the multi-way pipe joint; n air outlets of the multi-way pipe joint are communicated with air inlets of the n electromagnetic valves in a one-to-one corresponding way, respectively; an air outlet of any electromagnetic valve is communicated with an air inlet of one cylinder; a pressure instruction output end of the control part is connected with a pressure control end of the electromagnetic proportional valve; and n switch instruction output ends of the control part are connected with control ends of the n electromagnetic valves in a one-to-one corresponding way, respectively, wherein n is a natural number which is not less than 2.
