A significant portion of the SR-71's J-58 engine thrust was provided by turbine bypass air that was dumped into the afterburner. (See diagram.) Question: Could the same principle be used with a non-afterburning turbofan or turbojet engine? The idea would be to take excess intake air and channel it into the non-afterburning exhaust stream. The intended effect would be to increase the mass of the exhaust, thereby increasing thrust. Please be kind. I am not an engineer.Bronc
