Aircraft ejector performance test system and test method

The invention discloses an aircraft ejector performance test system, which comprises a test chamber, a gas cylinder and a slide simulator. An aircraft ejector is arranged in the test chamber, and thegas cylinder is connected with the aircraft ejector through a gas inlet pipeline. An air inlet is formed in the rear end of the test chamber, an air inlet chamber is formed in the front end of the test chamber, an air outlet is formed in the front end of the air inlet chamber, the rear end of the air inlet chamber is tightly connected with the test chamber, an opening is formed in the rear end ofthe air inlet chamber, the aircraft ejector body is arranged in the test chamber, and an aircraft ejector nozzle inserting opening is formed in the air inlet chamber. The slide simulator is located atthe air outlet, and the slide simulator is used for simulating internal back pressure change when a slide is inflated. The aircraft ejector performance test system is specially used for performing performance test on developme
