Ramjet Intakes

چکیده
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.

Unified Analysis of Internal Flowfield in an Integrated Rocket Ramjet Engine. I: Transition from Rocket Booster to Ramjet Sustainer
A comprehensive numerical analysis was conducted to study the internal flow development in an integrated rocket-ramjet (IRR) propulsion system. The study consists of two parts: transition from the rocket booster to the ramjet sustainer and combustion dynamics during ramjet operation. The physical model of concern includes the entire IRR flow path, extending from the leading edge of the inlet ce...
