Abstract

The main goal of aircraft bombing is its success in the destruction of the required target depending on the correct aiming and the correct moment of release. Different conditions, such as air speed, altitude, angle of release and the presence of wind, have a significant effect on the choice of the release moment to ensure target destruction. In this paper, a Six-degree of freedom (6DOF) mathematical model for the free fall bomb is presented describing the motion of the bomb in the three-dimensional space in the presence of stochastic winds. The aerodynamic coefficients for the free fall bomb are calculated through Missile Datcom computer program, however, these coefficients can be calculated either experimentally using the wind tunnel or a flight test; or mathematically through the Computational Fluid Dynamics (CFD). The stochastic wind affecting the trajectory of the bomb is defined by a velocity spectral represented by the Continuous Dryden Spectral. The contribution in this paper is the modeling and evaluation of the free fall bomb flight simulation in the presence of stochastic wind affecting the bomb flight trajectory.
