Aerospace Propulsion Systems
Statement released by NASA Dryden Research Center A ramjet engine is a
mechanically simple type of jet engine that has no moving parts (with the
possible exception of fuel turbopumps). A ramjet does not have a compressor or
turbine.
As far as the ramjet engine is concerned, it is getting all the things it needs to
operate— high-speed air, fuel in the form of carbon monoxide and hydrogen, and
an igniter— so it fires and produces usable thrust. SQUID's "flying stovepipe,"
aided ...

Fundamentals Of Compressible Flow
12.4 RAMJET ENGINE When the flight speed of a turbojet engine is very high,
say in the range of Mach number 2 to 4 the pressure rise in the diffuser (ram
pressure) is very high; at this flight speed the contribution of the compressor to
the total ...
Even though these assumptions are not realistic, they simplify the analysis of the
processes in the ideal ramjet engine. Furthermore, the ideal ramjet is a useful
concept and serves as a standard for comparing the performance of actual ramjet
...

High-Speed Flight Propulsion Systems
Alternatively, for, say, a Mach 7 system, the conventional ramjet engine might be
stretched to avoid transition to a true scramjet mode: alternatively the scramjet
takeover Mach number may be reduced or "stretched" down to eliminate the
ramjet ...
