Application of the Projection Pursuit Regression in Forecasting the Torpedo Velocity at Tube Outlet

Article Preview

Abstract:

Through the relations among the torpedo velocity at tube outlet, cylinder volume, cylinder pressure and emission valve size, we adopt the projection pursuit regression method and establish the model to predict the torpedo velocity at tube outlet. Through the comparison of experiment data and model prediction, fitting accuracy of this relation model is stronger and the projection pursuit regression is an efficient method which can research the initial ballistic trajectory of ship-launched torpedoes.
