Abstract
This paper studies the effect ofvectoring jet on the transverse aerodynamic characteristics of a slender body. Theresults show that: 1) the side force of the slender body caused byasymmetric vortices at a high attack angle can be reduced by vectoring jeteffectively. 2) with the increase of the attack angle, the affected zone of vectoringjet is expanded and reaches the nose of the slender body. 3) with theincrease of thepressure of the vectoring jet, the effect of jet on the side forceof the slender body is increased. The Mach number of the nozzle is thekey simulation criterion for the thrust vectoring test. The test wascarried out in D4 wind tunnel in Beijing University of Aeronautics andAstronautics.
