Jet engines, artwork Featured 4 May 2011 Print

Jet engines, artwork

Jet engines. Computer artwork comparing the designs of three types of jet engine - the turbojet (top), ramjet (middle) and scramjet (bottom). The turbojet is the oldest kind of general-purpose airbreathing jet engine developed during the 1930s. The ramjet, or stovepipe jet, was invented in 1913 but not produced until the 1940s. It does not have an internal compressor, using the engine's forward motion to compress incoming air. This means it cannot move an object from a standstill. The scramjet is a variant of the ramjet that was built in the 1950s and 60s, where combustion occurs in supersonic airflow - again relying on high speed to compress the air before combustion
