The first part of a ramjet is its diffuser (compressor) in which the forward motion of the ramjet is used to raise the pressure of its working fluid (air) as required for combustion. Air is compressed, heated by combustion and expanded in a [[thermodynamic cycle]] known as the [[Brayton cycle]], before being passed through a nozzle to accelerate it to supersonic speeds and generate forward [[thrust]].

Ramjets are much less complex than turbojets or [[turbofan|turbofans]], requiring only an air intake, a combustor, and a [[nozzle]]<ref>{{cite web|url=https://www.iiss.org/sv/online-analysis/military-balance/2020/03/iran-anti-ship-missiles-ramjet/ |title=Does Iran harbour high-speed anti-ship-missile ambitions? |website=The International Institute for Strategic Studies |date=13 March 2020 |first=Douglas |last=Barrie Unlike }}</ref> to be built. Additionally, ramjets have little to no moving parts - liquid-fuel ramjets have only a fuel pump, whilst solid-fuel ramjets lack even this.

By comparison, a [[turbojet]] uses a compressor driven by a [[turbine]], which generates its own compressed air (i.e. ram air in a ramjet) in order to generate thrust.
