Boundary layer diverter
WebThe diverter has to remove a boundary-layer for maintaining inlet performances, and should be designed to that it doesn’t greatly decrease aerodynamic performance of airframe. Therefore, the performance of diverter was evaluated in terms of a removing boundary-layer on the airframe surface and its aerodynamic drag. WebApr 14, 2016 · The diverter separates the inlet from the fuselage and the boundary layer, but this design feature causes the inlet weight and drag to increase and with higher maintenance requirements. It is...

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 Webboundary-layer flow in terms of the conserved variables (i.e., p, pu, pv, pw, and e) that was ... inlet, and boundary-layer diverter) except for the tail, (6) repeat 5 except replace standard wing with extended wing, and (7) repeat 5 except replace wing with spiroid wing. Though no publications were results, many presentations were made to Lockheed
WebHighly integrated boundary layer ingesting (BLI), offset or S-duct aircraft inlets have the potential benefits of reduced drag, size and weight by eliminating the boundary layer diverter and shortening the inlet duct; reduced ram drag by reducing the momentum of the inlet flow (ref. 1); and lower observability.
