Bonding technology, as one of the three aircraft manufacturing connection technologies, has been widely used in advanced aircraft. Foreign aircraft structure bonding technology has been quite mature, but Chinese helicopter bonding technology is in the process of continuous practice and improvement. EC175 helicopter represents the level of advanced aircraft in the world in the 21st century. It is the first equal risk cooperation project developed by China and western country. There are 31 kinds of honeycomb sandwich products with trapezoidal cross-section in EC175 helicopter. Affected by the trapezoidal closed sandwich structure, the failure rate of frame-honeycomb de-bonding is more and 63% in actual production, which seriously affected the production cost and restricted the progress. This paper analyzed the reasons from three aspects: structure, material and process. Through the optimization of bonding assembly process combined with product structure optimization, this kind of failure rate is effectively reduced and the technical level of helicopter structure bonding manufacturing is improved.
