ANALYSIS OF THE EFFECT OF THE GUIDED BOMB'S STRUCTURAL SYSTEM ON AERODYNAMIC CHARACTERISTICS

The paper presents results of calculations of aerodynamic characteristics and numerical simulations of flight of guided aerial bombs with a laser guiding system for their selected structural configurations. Moreover, the aerodynamic characteristics were calculated with different methods and the results were compared. A system of twelve differential regular equations supplemented by principles of steering was used to describe bombs spatial motion for simulation purposes. The main objective of the paper was the analysis of an influence which bombs structural configuration effects on aerodynamic characteristics and the identification of aerodynamic properties which are specific for these structural configurations and which could be preferred at designing of guided bombs. Exemplary results of calculations are presented in the paper.
