摘要

The shell (1) has a tail shaft (2) connected with a projectile body, and a wing tail unit (3) tail-laterally fastened in the tail shaft. The tail shaft comprises material i.e. aluminum alloy, which has high tensile strength than material i.e. plastic material, of the wing tail unit. The material of the wing tail unit has high elasticity or plasticity than the material of the tail shaft. The tail shaft serves for an admission of a propellant fire mixture and a basic charge, and is front-laterally provided with an external thread (5).
