The invention relates to a wing-in-ground-effect ship longitudinal coefficient estimation method and an aerodynamic characteristic analysis system thereof, and belongs to the technical field of wing-in-ground-effect ships. The method comprises the steps of preliminarily designing a ground-effect wing ship scheme, designing and manufacturing a wind tunnel model, obtaining data through three times of variable flight height tests, deriving a mathematical expression of a longitudinal aerodynamic coefficient of the ground-effect wing ship by using the data, and estimating longitudinal aerodynamic characteristics in any flight height state through the mathematical expression of the longitudinal aerodynamic coefficient of the ground-effect wing ship. Therefore, the test process is simplified and test times are reduced. According to the method, theoretical analysis is combined with a small amount of test data, so that the workload of the model blowing test is remarkably reduced, the research and development period is shortened, and the expenditure consumption is reduced. Meanwhile, according to the method, the key partial derivative and the relative ground-effect height in the stability calculation of the wing-in-ground-effect ship can be accurately obtained, the design efficiency and accuracy are improved, and the method plays an important role in promoting the development and application of the wing-in-ground-effect ship technology.
