Research and Application of Aero-engine Interface Measurement Technology

During the production and development of a certain type of aircraft, frequent sampling of the pipeline connecting the engine and the body occurred, which not only had a great impact on the production schedule, but also produced huge waste. In this paper, the measurement technology of laser tracker is researched, and digital measurement technology is applied for the first time in the assembly process of aeroengine. By using the laser tracker to measure the shape parameters of aeroengine in advance, the space coordinate system of the aeroengine is established, and the pipeline interface space is fitted. Coordinates and correction of pipeline manufacturing process parameters have greatly reduced the sampling of pipes in the assembly process of aero-engines. It is verified through actual production and manufacturing. After the application of laser tracker measurement technology, the average number of sampling times for connecting pipes for each aero-engine is reduced by 49% , Which greatly reduces the aircraft manufacturing cycle, and also contributes to the application of digital measurement technology in the production and development of weapons and equipment.
