Ejector Ramjet with Turbojet Fuel Rich Gas Generator.
Abstract
An ejector ramjet having a turbojet engine located in the air inlet to provide a fuel rich gas to the ramjet engine is described. The turbojet exhaust entrains secondary air in the ejector tube for the ramjet in the same manner as in a thrust augmentation system and increases the air's stagnation pressure. The mixture is burned in the ramjet dump combustor in a conventional manner. Fuel is supplied to the inlet of the turbojet compressor to provide precompressor cooling. The fuel flow to the compressor inlet is controlled to provide a stoichiometric mixture for the combustor. Additional fuel is supplied at the inlet of the turbine to provide cooling for the flow through the turbine and to provide a fuel rich mixture in the turbojet exhaust. (Author)
