Vuurpylmotors gebruik dieselfde beginsels vir aandrywing as straalmotor straalmotors<ref>[https://www.collinsdictionary.com/dictionary/english/reaction-engine Reaction engine] definition, Collins online dictionary: ''"an engine, such as a jet or rocket engine, that ejects gas at high velocity and develops its thrust from the ensuing reaction"'' (UK), or ''"an engine, as a jet or rocket engine, that generates thrust by the reaction to an ejected stream of hot [[exhaust gas]]es, ions, etc."'' (US) (retrieved 28 June 2018)</ref> met die enigste verskil dat vuurpylmotors nie atmosferiese lug ([[suurstof]]) benodig vir ontbranding nie. Die vuurpyl dra al die brandstof wat dit benodig. <ref>[https://www.collinsdictionary.com/dictionary/english/jet-propulsion Jet propulsion], Collins online dictionary definition.
