...Michael J. Brear; Jack L. Kerrebrock; Alan H. Epstein This paper discusses the requirements for the propulsion system of supersonic cruise aircraft that are quiet enough to fly over land and operate from civil airports, have trans-pacific range in the order of 11,112 km ( 6000 nmi ) , and payload...

... of results bears this out. Figure 2 shows the area averaged inlet pressure recovery versus the inlet mass-flow rate. The inlet pressure recovery is reasonable at the design mass-flow rate of 3.13 lb/s (Table 1 ), although it is roughly 2% below the pressure recovery of current, civil aircraft engine...

... equations aircraft Reduced-order modeling is a conceptually novel and computationally efficient technique that is recently used in analysis of unsteady flows. Unsteady flow eigenmodes are used to construct reduced-order unsteady flow models similar to the normal mode analysis in structural dynamics...

... due to the physical limits these phenomena impose on aircraft and missiles at extreme flight conditions. Demands for more maneuverable air vehicles have pushed the limits of current CFD methods in the high Reynolds number regime. Simulation methods must be able to accurately describe the unsteady...
