The Impact of Standard Deviation of Wind on the Bomb Flight in Atmospheric Turbulence

Abstract

Abstract The paper provides the simulation results of a small-diameter guided training bomb released during atmospheric turbulence. The simulation utilized a guided bombed devised at ITWL. Aerodynamic characteristics of the bomb were obtained from wind tunnel tests and from calculations made by the PRODAS programme. The simulation programme was developed based on a mathematical model describing a spatial motion of an aerial bomb moving in atmospheric turbulence. To describe a turbulence component, the model of stochastic processes proposed by Shinozuki was used. The manuscript includes examples of diagrams of basic parameters showing the bomb flight in a disturbed atmosphere. The analysis of the impact of the standard deviation of the wind on the change in the parameters of bomb flight was performed. The relationships between the parameters of bomb flight and the possibility to hit the target were provided.
