#论文# #水火箭# #飞行性能# #力学#

It is important to ensure the accuracy and stability of the flight path of the water rocket. This work develops a simulator with a numerical calculation program based on a mechanical consideration of the flight performance of a water rocket, analyzes the correlation between the flight distance obtained in the simulation and the estimated flight distance by applying a multivariate analysis method and verifies the validity of the flight distance calculated from the result.
