Research on the Experimental Cost Estimation Model in the Civil Aircraft Development Phase

With the increasing maturity of domestic civil aircraft technology and the entry of domestically produced civil aircraft into the market, civil aircraft enterprises are gradually strengthening their awareness and capabilities in cost control to achieve higher profit margins by controlling aircraft costs. For aircraft manufacturers, controlling development costs during the aircraft development phase is crucial. Test costs are an important component of development costs, and there is a large number and variety of tests during the civil aircraft development phase. Therefore, it is essential to establish a universal test cost estimation model to meet the manufacturer's need for efficient and accurate control of test costs. This article introduces a test cost estimation model for the civil aircraft development phase, considering nine types of costs, including labor costs, equipment costs, and fuel costs. The rationality of this model is validated through research, calculations, and result comparisons.
