Research on the maturity evaluation method of the transfer phase in flight test

In the development of new aircrafts, flight test is a crucial link between the manufacturing process of the prototype and the acceptance of the final product. Based on the division of test phrase in China, this chapter explores the construction ideas of flight test maturity models. In terms of the technology status, integration status, manufacturing status, flight test status and RMS status, this chapter describes the flight test maturity, and establishes a more comprehensive and objective model —the Flight Test Maturity Model (FTMM) with specific description of each level of the test flight maturity characteristics. In this chapter, Flight state of maturity serves as the theoretical basis for the evaluation of the flight test phase, the Attribute Comprehensive Evaluation method is also used to test flight maturity. An example is given using flight testing maturity model to evaluate the test status of a new type of aircraft, which verifies the correctness of the model and its applicability in the flight test work.
