Abstract:

The supersonic combustion ramjet, or scramjet, is the engine cycle most suitable for sustained hypersonic flight in the atmosphere. This article describes some challenges in the design of the inlet or intake of these hypersonic air-breathing engines. Scramjet inlets are a critical component and their design has important effects on the overall performance of the engine. The role of the inlet is first described, followed by a description of inlet types and some past examples. Recommendations on the level of compression needed in scramjets are then made, followed by a design example of a three-dimensional scramjet inlet for use in an access-to-space system that must operate between Mach 6 and 12.
