The invention discloses an airplane porthole component performance test system comprising an industrial control computer, a programmable logic controller, an airplane porthole component test device, and an air source. The industrial personal computer is used for being connected with the programmable logic controller, transmitting a pulse signal of controlling the airplane porthole component test device, and receiving a current signal, processed by the programmable logic controller, of the airplane porthole component test device. The programmable logic controller is used for receiving a pulse signal whereby the industrial control computer controls the airplane porthole component test device, and receiving and processing the current signal from the airplane porthole component test device. The air source is used for providing the airplane porthole component test device with air. The airplane porthole component performance test system is capable of effectively simulating flight temperature and pressure parameters of an airplane, is capable of truly indicating the physical performance of airplane porthole glass during actual operation and the influence of component assembly upon the performance of the airplane porthole glass, is also capable of automatically intercepting and storing test data in performance test process into the industrial personal computer, and has an extensible test function.
