Ramjet vs. Ramet — What's the Difference?

A ramjet, sometimes referred to as a flying stovepipe or an athodyd (aero thermodynamic duct), is a form of airbreathing jet engine that uses the engine's forward motion to compress incoming air without an axial compressor or a centrifugal compressor. Because ramjets cannot produce thrust at zero airspeed, they cannot move an aircraft from a standstill.

A physiologically distinct organism that is part of a group of genetically identical individuals derived from one progenitor, as a tree in a group of trees that have all sprouted from a single parent plant.

A jet engine that propels aircraft by igniting fuel mixed with air taken and compressed by the forward motion of the aircraft.

(botany) A clone (individual member of a genet).

(aeronautics) A jet engine in which forward motion forces air into an inlet, compressing it (as opposed to having a pump type device compressing the air for combustion with fuel), and where combustion is subsonic.

A simple type of jet engine; must be launched at high speed
