Abstract: | The design of supersonic three-dimensional inlets using the V-shaped body forming a two-dimensional flow including an initial
oblique shock wave and a subsequent isentropic compression wave is considered. Such a flow appears attractive for inlets design
due to a possibility of obtaining high compression levels of external flow over the inlet ramp with small losses of the total
pressure. Numerical computations of the flows around the designed configurations were carried out in design and off-design
regimes using Euler code. The flow structure was identified, the aerodynamic characteristics of the inlets were determined.
The investigation covers the range of supersonic speeds corresponding to the freestream Mach numbers M∞= 1.8−2.5. |
