Numerical Simulation of Fluidic Thrust Vectoring in the Conical Nozzle

Abstract

The application of fluid injection into the divergent portion of a supersonic nozzle to release the pushed vector is an attractive alternate to conventional thrust vectoring systems. Indeed, it can replace mechanical complexes. In recent years, this new thrust vectoring technology is the subject of numerous experimental and numerical researches, and has allowed countless applications due to its many advantages. A thrust vectoring concept is currently being applied to new-generation fighter aircraft equipped with jet engine. Fluidic thrust vectoring also finds application in satellite altitude control systems; this principle reduces the number of nozzles used. This study is based on ANSYS-FLUENT and analyzes the different phenomena involved. The results of thrust vectoring performances (angle of deviation, efficiency, lateral forces, etc.) are compared to those in the bibliography.
