“…Such an engine was first proposed under the name of AJAX (Kuranov AIAA 2001) [5] (Gurijanov AIAA 1996) [6], and another was studied under the name of MHD-Arc-Ramjet in which an arc heating device was used to return energy (Tang AIAA 2006) [7] (Tang AIAA 2007) [8]. In order to make MHD interactions effective, the appreciable electric conductivity of airflow is achieved using equilibrium ionization technologies at high enough flow temperatures (Park JPP 2001) [9], or nonequilibrium ionization technologies at medium flow tem-peratures (Sergey AIAA J 2001 ) [10] (Sergey JPP 2002) [11] (Park JPP 2003) [12]. The characteristics of the ramjet with energy-bypass is shown in Fig. (1) (seeing (Tang AIAA 2006) [7] for further details).…”

In order to provide a basis for the establishment of an applicable strategy for the development of aero-engine thermal cycles, the evolution of compression processes in aero-engine thermal cycles is reviewed in this paper by analyzing the compression requirements for the injection or extraction of energy. It is therefore concluded that the injection of energy in the compression is required for applications in low speed ranges, for example, the injection of energy in turbojet compressors; the method of adiabatic compression is desirable for applications in intermediate speed ranges, for example, shock interactions for ramjets/scramjets; and the extraction of energy is needed for applications in high speed ranges, for example, the extraction of energy in ramjets with energy-bypass. The injection or extraction of energy in the compression heavily depends on the aero-engine performance required for applications in different speed ranges.
