In view of the problems of low efficiency, low precision and no joint test of the aircraft flap equal quantity distributor, an intelligent detection device with industrial computer as the core was designed through indepth analysis of the working principle and testing project requirements of the flap equal quantity distributor. The integrated detection of flow resistance performance, flow difference performance, congestion performance and joint debugging function of the flap equal quantity distributor was realized, and the detection efficiency and accuracy were improved. The research results has practical and military value.
