Abstract:
      Objective To investigate the causes for frequent failures of airborne products in the qualification test phase, and improve the development process of airborne product. Methods Fifty environmental identification test failures of the helicopter airborne products were collected and analyzed. Results The environmental test failures were mainly three proofings and vibration test failures. The causes of the failures were mainly the following three points: improper selection of materials and surface treatment, design flaws and relaxed quality procedures. Conclusion According to the analysis results, airborne products are re-quired to arrange environmental development tests as early as possible, establish the environmental database, simulate design and strengthen quality management in the design process, so as to avoid frequent failures of airborne products in the identification testing phase.
