Hypersonic vehicle design using inward turning flow fields

Novel inlet–airframe integration methodology for hypersonic waverider vehicles

“…Despite the long-lasting existence of the MOC methodology, it is still extensively used in the design of modern hypersonic vehicles [28]. Kothari et al [29] applied the MOC to the design of air-breathing scramjet-powered hypersonic vehicles. Based on the MOC, Barkmeyer et al [30] investigated the inverse waverider design for inward turning inlets.…”

Iso-Contraction-Ratio Methodology for the Design of Hypersonic Inward Turning Inlets with Shape Transition

“…According to (10), Cr 03 and M 3 contour plots with respect to the π 30 -σ 30 plane is shown in Figure 2 when the inflow Mach number is 5.4. Cr 03 and M 3 contour plots with respect to the π 30 -σ 30 plane is shown in Figure 3 when the inflow Mach number is 3.5.…”

“…The method translated the design problem of a three dimensional flowfield into that of a set of two dimensional conical flowfields. To reduce the pressure gradient between two adjacent slices, the set of conical flowfields were designed to share the same generatrix and have different radial deviation values 10 . However,the reflected shock was then not handled and hence there were additional shock reflection in the isolator.…”

“…14). Ideally, the funnel-like inlet configuration offers more air capture and more efficient compression to the inlet throat for less wetted area, with an accompanying more efficient expansion through the radial nozzle than does its two-dimensional or conical counterparts.…”
