Aerospace industry is a large-scale and complicated system. It is important to use systematical theory and methods to improve management. With the popularity of space product contract on research and production, study on price estimation become much essential and urgent. This paper aims for the price estimation of solid rocket motor. Firstly, the price feature of motor and the price-making situation in the Fourth Academy of China Aerospace Science & Technology Corporation are introduced, and the imperfections are pointed out. Secondly, the predict methods of armament cost are induced. Thirdly, the estimating methods and models used in the Fourth Academy are mainly discussed, and Parametric Cost Estimating is determined to solve the problem in future. Then influential factors are analyzed, new method and models are presented. The emphasis in the paper lies in factor-analysis and establishment of estimating model. Through correlate analysis and cluster analysis, the main parameters are selected. By curve estimation and stepwise regression, the price-estimating model of solid rocket motor is established.
