This paper deals with the design of a deformable nose for the non-penetrating projectile in order to prevent its body deformation. Numerical, analytical and experimental studies have been carried out to analyze the effect of different nose shapes on the projectile deformation when it hits the brick wall. The projectile consists of an aluminum nose, a thin-walled steel cylinder body, and an end connector. This non-penetrating projectile can be used to carry a cargo that must reach its destination safely, for example in firefighting applications. To pursue this goal, the criterion utilized for the best design in this paper is stress and strain analysis. The geometric shape of the noses includes three types: type (a), type (b), and type (c). The first type of nose was flat shape. This nose was detached from the projectile by impact and did not prevent the projectile deformation. The second type of nose was a combination of flat and conical shapes. The projectile was also deformed by this nose. The third type of nose was a combination of flat, conical, and spherical shapes. Due to the maximum absorption of the impact energy, this type of nose prevented the deformation of the cargo and projectile.
