Ramjet Intakes
Abstract
Intake design for supersonic engines, in common with other engineering design problems, is application dependent and the true challenges are in meeting performance targets over the required Mach and Reynolds number ranges while complying with the multitude of constraints imposed by the aircraft/missile and its mission. The fundamentals and limitations of efficient ram compression are well understood and since NASA, DTIC, RTO and AERADE provide free public access to a large database of intake experiments conducted in the 1940s to 1970s, the designer should be aware of problems encountered and the fixes applied during previous testing of isolated intakes. The outline of this lecture is a brief tour of some historic supersonic intakes discussing the features that enable the intake to meet its requirements and applying some reverse engineering to deduce how the designers appear to have approached the problem. The tour is combined with an introduction to tailoring compressive flow fields by exploitation of one and two dimensional flow elements.
