Ramjet Engine for Power Generation - A Review
Keywords:
Ramjet, Supersonic, Diffuser, Structural MemberAbstract
A method of power generation by using the ramjet engine. Ramjet structural components to provide inlet compression, the combustion chamber and an outlet nozzle are provided at one or more circumferentially spaced locations along the periphery of the low aerodynamic drag rotor. Ramjet compression occurs by impingement of an inlet air stream between the rotating inlet structure and an adjacent stationary wall. The compressed air inlet stream provides oxygen for mixing with the fuel, such as natural gas, others suitable hydrocarbons, or hydrogen, which is supplied to the ramjet combustion chambers to produce expanding combustion gases. Such gases escape out through the nozzle formed between the rotating outlet structure and the stationary wall. The ramjet operates at supersonic velocities, and preferably in excess of mach 2.0, to produce shaft energy. The rotor rotates about an axis defined by an outlet shaft. The rotor acts as the structural member which transmits to the output shaft the thrust generated by the ramjets. Thermal and mechanical energy in escaping combustion gases may also be utilized to increase the overall efficiency of the ramjet engine.
