A kind of general assembly test method of aircraft system

Abstract

The invention discloses a general assembly test method of an aircraft system, which comprises the following steps: 1) conduction of the cable network of the whole aircraft; 2) power supply system test; 3) task system electrical measurement; 4) electromechanical power-on test; 5) bus 6) Inspection of hydraulic system; 7) Inspection of lighting system; 8) Inspection of take-off and landing, landing gear; 9); 10) Inspection of fire protection system; 11) Function inspection of each subsystem; 12) Inspection of engine; Inspection; 14) flight control test. The present invention decomposes and merges the test work, so that different system test items of the same type are merged and tested; the test work is layered and tested, and from the perspective of safety, the test is performed layer by layer to improve the safety and reliability of the power-on test and reduce the test risk; step by step. The test is converted into a function and performance test; the critical path method and parallel test method are used for design; the test process of the fixed aircraft system has a guiding role.

Description

technical field [0001] The invention relates to the technical field of aircraft performance testing, in particular to an aircraft system assembly testing method. Background technique [0002] The aircraft system is a complex system. In order to ensure the correctness and reliability of the system, a series of performance tests need to be carried out on the aircraft during the manufacturing process. In the past, the aircraft system adopted a distributed layout, that is, the systems were relatively independent. If signal cross-linking was required between the systems, communication lines or hard lines were added. After the system was installed, a single system could independently complete the system test. With the improvement of aircraft system integration, modern aircraft are based on the whole machine network platform, a large number of high-speed buses are used, and the system is highly integrated. Due to changes in the aircraft system architecture, the traditional single ...

Problems solved by technology

Due to changes in the aircraft system architecture, the traditional single system test method can no longer meet the test requirements of modern aircraft. As an important link to ensure the installation and integration of aircraft systems and the correctness of system functions, the aircraft assembly system test needs to cover the entire process. Component-level testing, gradually integrated into system testing, and comprehensive joint debugging of the whole machine

[0003] The existing test process in the domestic aircraft assembly stage is based on the performance test requirements of each subsystem and the previous experience to arrange production. Due to the wide variety of test items and the cross-linking and coupling of signals between the various subsystems of the aircraft, there is a tight gap between the test items. Therefore, the test process needs to meet a specific test sequence. The whole process is very complicated, and it is easy for operators to perform repetitive work. During the test process, the failure problems encountered are often biased, and it takes more time to coordinate with specialized personnel to arrange Therefore, it greatly affects the test efficiency; some test items are independent of each other and do not interfere with each other, but the existing process test process is basically carried out in series, which makes the test cycle longer and cannot meet the production needs; the existing test process is not carried out Specific specifications, risk of on-board quality accidents
