Flow Features and Aerodynamic Analysis of the Canard Missiles

In this work, a grid method for determining the aerodynamic characteristics of canard missiles, taking into account the effects of the oblique blowing is developed. Based on a comparison with NASA experimental data, the accuracy of the calculation results obtained by this method was tested. A comparative analysis of the canard missile flow spectra in the modes with the absence and presence of the oblique blowing is carried out. It is shown that the main mechanism for the oblique blowing formation is the interaction of vortices arose during the flow around the rudders and vortices coming off the missile body.
