Calculation And Analysis The Aerodynamic Characteristics Of The Glide Bullet

This thesis presents the empirical method for prediction the aerodynamic coefficients on glide bullet. McCoy empirical method , Newton method , Van-Driest method , Kpachob,H.X empirical method, Moore empirical method is applied and except these empirical, the little disturbing theory, taper flow theory , lifting surface theory are also applied. Through these theory and empirical method, this thesis presents a suit of methods to calculate the aerodynamic characteristics of the body alone , tail alone , wing alone and the wing-body-tail combination at subsonic , transonic , and supersonic, bases these methods, author has developed the computation program. Three calculation example are used in this thesis, they are 122mm-missile bullet,250kg aviation bomb and a glide bullet with I,II two models. The aerodynamic coefficients results of the calculation were coherent with the result of the wind tunnel experiments, through the comparing the result of the two models of the glide bullet, the affect of the Mach number, the angle of attack and the wing on aerodynamic characteristics of glide bullet is analyzed, this set of methods are suitable for the calculation of the glide bullet.
