Webwedge diverter was about 0.36, based on diverter frontal area, while the drag coefficient of the 40° wedge was about 0.47. INTRODUCTION The majority of the published force data on wedge type boundary-layer diverter systems treats primarily the pressure drag (refs. 1 to 5). A few measurements of skin-friction drag are reported in references Web1993). In boundary layer diverter intake configuration, diverter separates the inlet from the fuselage and the boundary layer. This design feature not only causes added intake weight and drag, but maintenance requirements are also increased (Mattingly 2002). This intake type is successfully designed and tested on F-16 aircraft
