Normal Probability Distribution and Process Capability Index Analysis Determine the Reference Value for Continuity Requirements of Aircraft External Surface
摘要
To ensure the aerodynamic performance of the aircraft, the continuity requirements of the external surface are determined to restrain the deviation between the manufacturing external surface and the design external surface of the aircraft. When formulating the continuity requirements of the external surface, we need to consider whether the manufacturing can be realized. This paper proposes the normal probability distribution analysis and process capability index analysis of the existing manufacturing detection data to provide the manufacturing reference value for the continuity requirements of the external surface. At present, this method has been verified and applied in practical work.
