Aerodynamic characteristic of a canard guided rocket

Abstract

The computational fluid dynamics (CFD) numerical simulation was used to investigate the aerodynamic characteristic of a canard guided rocket based on the technology of high quality point-to-point multi-block structured grid. The results of numerical simulation and experiments showed that the method is highly credible, and the method could be used to the rockets with semblable configurations. The canard guided rocket was designed with different noses, canards and fins. The N-S equations were solved numerically by the finite volume method, and the multi-grid method was adopted to accelerate the convergence. With these strategies the aerodynamic characteristics of rocket, nose, canard and fin were educed, and the change law was summarized. The results will provide the support for the optimization of anard guided rocket in engineering design.
