Специальность: Машиностроение (Mechanical engineering).Mortar shell design is one of the most critical components in defense organization of projectile design. Unavilability of data and literature regarding artillery projectiles and rocket warheads, are considered to be one of the main contributors for the failure of manufacturing projectile in a local industry. The need for this study is to design and fabricate this type of mortar shell in Ethiopia itself. Thus, the primary objective of this thesis is to develop a ballistics model of mortar shell and predicting the performance of mortar casing by ANSYS a finite element analysis package. Initially, the model is designed as a simplistic ballistic model capable of predicting the pressure and thrust generated by a propellant from a given set of input parameters. Its structure was determined on the basis of gun design empirical, experimental investigations of ballistic research laboratories and weapon design of ammunition and artilleries of high explosive calibers.Content:
