The aviation industry, in the past few decades, is interested in the supersonic flight. The defence sector of almost all the nations are involved in the design of modern supersonic fighter aircraft, ICBMs and innovations in faster air transport. Even most of the space agencies are interested in finding out the newer technologies of launching the satellites. In brief, Aeronautics has stepped into the next generation of explorations and innovations. Ramjet is one of the main sources of power for supersonic flight. Ramjet powered missiles, Ram Rocket, Ramjet assisted supersonic fighter will lead the aviation sector in the near future. Combustion instability and better fuel mixing are some of the problems encountered in Ramjet combustion. This research work involves in the study of air-fuel mixing in the combustion chamber to find out better solution to overcome the combustion instabilities.
