Simulation Study Of The Flight Characteristics Of The Small Caliber Apds

This thesis presents theoretic analysis, experimental studies and numerical simulation on the rule of separating motion of projectile x free motion close to gun of sabot , flying characteristic of projectile under sabot and projectile's function each other on "30mm" armor piercing projectile.The main contents of study are as followings:1). Based on emperiment of "30mm" armor piercing projectile's discarding sabot close to gun, study discarding sabot motion and process , and analysis discarding sabot characterstic , the possibility of disturb on sabot f^rm main gun under the disturb field of double gun.2). Using FLUENT software, calculate the aerodynamic parameter of projectile and sabot.3). According to motion equations of sabot and parameter obtained above , calculate and analysis flying motion variety of sabot.4). Based on 6 free degree projectile's motion equation , using aerodynamic parameter of projectile, calculate exterior ballistic^ analysis the rule of variety of velocity and angle of attrck.5). Using tools of animation .according to flying pose of armor piercing projectile and data from experiment,actually animate the track of ballistics whole procedure.lt can dynamically simulate to obtain visual scientific calculation and accurate simulation in real meaning.
