guidelines on conceptual and preliminary design of hypersonic waveriders with different number of inlet ramps

Many of the savants in the field of aeronautical engineering presume that air-breathing hypersonic flight is the last boundary of aerial vehicle design to be pushed back. a “waverider,” using the scramjet engine cycle as its propulsive system, is an auspicious design configuration for the prospective hypersonic transport vehicles of the future. two-dimensional cfd analysis and case-to-case study of three pre-defined waverider configurations with 2-ramp, 3-ramp, and 4-ramp inlet geometries are carried out in the hypersonic flight regime of mach numbers 5, 6, and 7. this is done in an attempt to study the single-oriented and correlative-oriented impacts of increasing/decreasing the number of inlet ramps and increasing/decreasing the flight mach number upon the behavior of final aerodynamic coefficients and ratios. the paramount outcome of the present work is the generation of some tables that can be utilized as primary guidelines for aeronautical design engineers who are designing waverider configurations on a preliminary basis.
