Theories Analysis And Numerical Simulation Of Extended Range Ballistic Trajectories

In studying the predicted research project named "Total Technique Studies of Super-Long Range" in the Tenth Five Year Plan, two kinds of proceed projects are presented to meet the requirements of the research project in this thesis: one is rocket pushing together extended range with glide; anther is compound extended range together extended range with glide. The present investigations focus on theoretical analysis and numerical experiment for the first proceeded project. As regard to the projectile geometry in the first project, the project of the exterior ballistic extended range based on the projectile's geometry and size here is designed. The linear glide method among the projects is studied carefully. The influences of the reasonable point to fire for rocket pushing segment on artillery range, and the influences of glide point of departure, glide start speed, glide the at an final point with glide to control the parameters on artillery range are considered theoretically. A reasonable start speed scope for glide and extended artillery range, a suitable start glide point, the reasonable ballistic degree of attack in glide project are brought out, and the final glide point is analyzed as well. The synthetic optimum and design are completed, and the optimum results are given as well. Based on the first project, the exhausting time in the boattail and extended range segment influences on artillery range are considered. The suitable exhausting time is obtained. Finally, the secondary developing has been done in Visual Basic language. Some visual windows and simple database are created. They can be used to show the static or dynamic curves for aerodynamics and exterior ballistic testing data.The research works in this thesis may not only provide the scientific guides for choosing and deciding the research project, but also will make an important role for its future development.
