Problems solved by technology

In addition, since the flight parameter recording system is about to conduct a test flight after the aircraft is powered on, once there is a fault at this time, the time left for troubleshooting is extremely short, and more professional personnel associated with the system are required to assist in troubleshooting. In order to troubleshoot, it is necessary to repeatedly disassemble, assemble and debug. The operation is complex, difficult to implement and easy to cause other products to fail again.
Therefore, the risk of system performance verification by using the aircraft as a platform is relatively high

Embodiment Construction

[0035] This method is suitable for the trial repair of a certain type of flight parameter recording system.

[0036] Introduce according to the trial repair process:

[0037] 1. Realization of product testing method before trial repair

[0038] ⑴Summary of procurement of test equipment and solutions to existing problems

[0039] After market research and technical analysis, our factory purchased the test equipment of the flight parameter recording system. However, due to the technical blockade of the equipment manufacturer, the pin definition of the product is not provided, and further implementation of the product failure cannot be carried out. Through the principle analysis of the product and the reverse test of hundreds of pins of the equipment, the pin definitions of each product and each socket of the equipment are obtained, which provides technical support for troubleshooting of products and equipment. In addition, although the supporting materials of the equipment hav...

Abstract

The invention discloses a test repair method for a certain type flight parameter recording system. The method comprises the following steps: realizing a product testing method before test repair and solving main problems solved in the test repair process (solving problems during decomposition and surface treatment; eliminating a fault that an electric switch on an aircraft cannot be opened and perfecting equipment detection performance; eliminating data out of tolerance of a sensor and transducer assembly and improving the contact performance protection of a detection equipment connector; solving frequent faults caused by unqualified output voltage of an exhaust temperature measuring module and partial circuit surveying and mapping). According to the test repair method for the certain typeflight parameter recording system provided by the invention, the work efficiency is increased, and risk of operational complexity of performing system performance verification by taking the aircraftas a platform and repeated faults of related products can be avoided. In addition, due to the difficult self-repair process, and much new knowledge can be known and mastered. A solid foundation is laid for repair of imported products in future.

Description

technical field [0001] The invention relates to a trial repair method of a certain type of flight parameter recording system. Background technique [0002] A certain type of flight parameter recording system (referred to as "flying reference") is an important airborne electronic device on the aircraft, and its role is more and more closely integrated with the flight safety of the aircraft, aircraft maintenance and flight training. Combining the flight parameter recording system with the expert system of the ground data processing station, it can monitor the working conditions of related systems on the aircraft, such as engines, air data, heading attitude, flight control, fuel and other systems, and can also monitor the flight quality. Monitoring, thus forming a closed-loop monitoring system for flight safety. The processing results of flight data can be used as an important basis for analyzing problems in maintenance, flight training, safety inspection and other departments...
