【 摘 要 】

This paper presents the study which was intended to identify the optimum geometries for different operating conditions of a Coanda bases Fluidic Thrust vectoring using ACHEON nozzle (Aerial Coanda High Efficiency Orienting Nozzle). This computational study was done utilising the software ANSYS. The study is aimed at optimising the Coanda surface by identifying the most appropriate geometry of the Coanda surface for different operating conditions. The radius of curvature of the coanda surface has been modified for different studies and also different levels of truncation of the coanda surface has also been done. In this study a variation in the radius is from 52.73 mm to 62.67mm.
