Marquardt RJ43
Encyclopedia
The Marquardt RJ43-MA were ramjet
engines used on the CIM-10 Bomarc missile and on the D-21
drone. They were engineered and built by the Marquardt Corporation.
Ramjet
A ramjet, sometimes referred to as a stovepipe jet, or an athodyd, is a form of airbreathing jet engine using the engine's forward motion to compress incoming air, without a rotary compressor. Ramjets cannot produce thrust at zero airspeed and thus cannot move an aircraft from a standstill...
