Abstract: In this thesis, through the application of the dimensional analysis method, we get the scaling criterion of the movement parameters of the cylinder in the land ejection scaling test, and by the application of the equation analysis method, we get the scaling criterion of the gas generator injection into the cylinder. On this basis, a radial scaling model suitable for the land ejection test is established, a scaling scheme is proposed, and the motion parameters of the scaling model are calculated. Compared with the full-size model, the accuracy of the reduced scale model is verified. At the same time, the main factors affecting the accuracy of radial scale tests are analyzed.
