Prediction of aerodynamic coefficients for irregularly shaped body using numerical simulations
Article history: Received 20 February 2018 Received in revised form 26 April 2018 Accepted 2 May 2018 An evaluation of aerodynamic forces and moments that act on an irregularly shaped body (fragments of HE projectile) moving at high velocities was made, using numerical simulations, analytical models, and CAD methods. Using the results obtained for aerodynamic forces and moments, and known values of body exposed area, aerodynamic drag and lift coefficients were determined for different body orientations and different flow velocity. Analysis of the influence of the body front surface and body slenderness on the position of the maximum CD value (on the CD (Ma) curve) was performed.
