Evaluation of the possibility of bomb flight control

This paper presents theoretical model dedicated to a guided bomb. A mathematical description of the six-degrees-of-freedom motion of the bomb is shown. Particular attention was paid on aerodynamic forces and moments generated by additional control fins mounted on the front part of the bomb. Exemplary results of a numerical simulation of bombing are submitted and conclusions focused on the possibility of flightpath control are formulated. The paper concerns on the equations of bomb spatial motion and kinematic relations expressed making use of moving coordinate systems, the common origin of which is located at the centre of mass of the bomb. The set of equations of the rotating motion about the centre of mass in the body-fixed reference frame is presented. Aerodynamic forces and moments acting on the bomb are described. Coefficients are determined using the PRODAS software with detailed geometry of the LB-10M bomb. The coefficients were determined for different Mach numbers from 0.4 to 0.8. The important task was research investigations of aerodynamic characteristics with a wind tunnel and a set of experiments in real bombing conditions.
