Abstract: This paper investigates the aerodynamic actions acting on a tails-less projectile with constant mass. To define the overall aerodynamic strength acting on the projectile is used a semi-empirical approach based on the study of the main physical phenomena the strength is originated from. The problem of the interaction of the projectile and the air is split into some elementary problems involving each aerodynamic action, the sum of which gives the overall aerodynamic strength. This approach allows to clarify the physical meaning of the aerodynamic strengths acting on a projectile (drag, lift, etc). The overall aerodynamic momentum is defined in an analogue way using the definition of the aerodynamic strength. The last paragraph reports some synoptic tables and figures that summarize the former paragraphs.
