理想冲压喷气发动机、理想涡轮喷气发动机和理想涡轮风扇发动机的参数循环分析是众所周知的，并有文献记载。这些理想推进系统的参数数学描述有助于理解这些发动机相互比较以及与使命要求比较时的优点和有用的工作条件。人们还知道，当在高超音速马赫数下工作时，超音速燃烧冲压式喷气发动机在产生比推力方面比其它发动机优越上级。本文的目的是对理想的超燃冲压发动机进行参数循环分析。这就允许用简单的代数方程来描述理想的超音速燃烧冲压式喷气发动机，类似于理想的冲压式喷气发动机、理想的涡轮喷气发动机和理想的涡轮风扇发动机。
Parametric cycle analyses for the ideal ramjet, ideal turbojet, and ideal turbofan engines are well known and documented. The parametric mathematical descriptions of these ideal propulsion systems are useful for understanding the advantages and useful operation conditions when comparing these engines with one another and with mission requirements. It is also known that the scramjet engine is superior in producing specific thrust over these other engineswhen operating at hypersonicMachnumbers. The purpose of this work is to present a parametric cycle analysis for the ideal scramjet. This permits the description of the ideal scramjet via simple algebraic equations similar to that for the ideal ramjet, ideal turbojet, and ideal turbofan engines.
