The test of flow un-uniformity in fuel manifold is the main testing project for the parameter of aircraft engine fuel mani-fold. Aiming at the testing project and the relevant requirements,the schematic diagram of the hydraulic control system for tester was provided,the hydraulic control components and methods of flow detection suitable using in particular working conditions were sugges-ted,and the ways of working on the closed-loop control of the large-scale pressure were described. According to the specific require-ments of liquid temperature in the inlet of fuel manifold during testing,the working principle of closed-loop temperature control was raised. Two types of fuel manifold can be tested by this testing machine.
