Computational aerodynamic study of a supersonic reference projectile

aerodynamic shape optimization of supersonic projectile fins

the aim of this work is to find an efficient aerodynamic-based design algorithm for projectile fins and configuration shape optimization. three-dimensional supersonic flow over a projectile with fins at much number 5 and one degree angle of attack was studied. the runge-kutta method and multi-block technique was used to solve the governing equations. a basic configuration was assumed for the fi...

Unsteady Aerodynamic Simulations of a Finned Projectile at a Supersonic Speed With Jet Interaction

Transonic and Supersonic Overtaking of a Projectile Preceding a Shock Wave

In this paper, two-dimensional and axisymmetric, time dependent transonic and supersonic flows over a projectile overtaking a moving shock wave are considered. The flow is simulated numerically by solving full time averaged Navier-Stokes equations. The equations are linearized by Newton approach. The roe’s flux splitting method, second order central difference scheme for the diffusion terms, an...

A Numerical Study into a Local Protuberance Interaction with a Fin on a Supersonic Projectile

A preliminary investigation into the interaction of a local protuberance with a fin on a supersonic projectile has been completed. Computational fluid dynamics have been utilised throughout. A model has been computed for Mach numbers between 1.5 and 4 and between 0° and 8° angle of attack. Validation of the results has been undertaken quantitatively through comparing normal force and pitching m...
