The stress on low observability (LO) characteristics has directed fighter aircraft forebody configurations toward contours which generate strong vortices in the vicinity of the fuselage half-breadth, in both maneuvering and cruising flight conditions; these vortices can reduce integrated inlet performance and degrade inlet/engine compatibility. The present investigation has employed high-speed experimental flowfield surveys to characterize advanced LO-contoured fighters' inlet-approach flowfields. Attention is given to forebody angle-of-attack-induced shielding of the inlets at various Mach numbers.
