Abstract: MI-Jet or medium independent jet engine is a new conceptual design which can be used in any gaseous atmosphere or in any planets with an ISP greater than that of the existing rocket engines. MI engine’s thermodynamic concept could be utilized to develop turbojet, ramjet and scramjet engines that can operate in Martian environment with higher ISP. The same concept could be extended for the development of MI-Turbojet, MI-Ramjet and MI-Scramjet engine for Earth atmosphere with an ISP as high as 200% of the ISP of existing rocket engines, but less than that of the conventional scramjet or other air-breathing engine. However the operational complexity of the MI-Jet will be significantly lower than that of the existing scramjet engine.
