Characteristics Analysis and Study for Area-Changing and Damp-Increasing Range Correction Device
A new kind of correction system with damp-increasing area-changing was analyzed and proposed through analyzing researches of one-dimension trajectory correction at home and abroad. And carried out an analysis of the change and the influence that caused by drag coefficient, lift coefficient with angle-of-attack and wind speed under different area. The mathematical model was proposed between increased drag coefficient and variable area opened by the damper. Feasibility and rationality of the new system were verified by simulation analysis. Furthermore, the damper can open at the right place under the system requirements. By researching aerodynamic characteristics of the projectile fixed this device would promoted the further design of damp-increasing range correction system.
