Low-speed experimental study of the vortex flow effects of a fighterforebody having unconventional cross-section

Aerodynamic Analysis of a Generic Fighter with a Chine Fuselage/Delta Wing Configuration Using Delayed Detached-Eddy Simulation

“…For certain flight conditions these vortices interact with the wing leading edge vortices, and improve the maneuvering lift capabilities. 1 However, for other flight conditions these vortex interactions are detrimental to the aerodynamic characteristics of the vehicle. This is especially true when the fighter experiences moderate to low angles of sideslip at angles of attack in excess of 25˚.…”

“…2 The vortex interactions of chine fuselage/delta wing configurations have been extensively investigated experimentally. [1][2][3][4][5][6][7][8] Erickson and Brandon 1 were amongst the first to investigate the nonlinear aerodynamic and stability characteristics of a chine-shaped forebody and delta wing configuration. They concluded that at high angles of attack the chine-wing vortex system was susceptible to severe asymmetries in the core breakdown positions in sideslip.…”
