Analysis and Research of Water Sprays in Civil Aircraft

In the process of designing a new type of civil aircraft, the main manufacturer needs to obtain the type certificate, including the water spray test. Using the method of engineering estimation at the beginning of the design, we can effectively find the potential design problems in the initial stage and reduce the risk of subsequent tests. This paper studies water sprays under different runway water depths, tire parameters and speeds, obtains the basic track of the water sprays and determines the risk of the water sprays in compliance of civil aircrafts. It finds out the causes of the water sprays, analyzes them, and guides the model design.
