An analytical investigation of the effectiveness of water injection for engine-inlet matching and thrust augmentation was made at Mach numbers from 1.5 to 2.0. One-dimensional equations for complete evaporation in a constant-area channel were applied to a fixed-geometry inlet, and its flight performance was compared with bypass and translating-spike inlets.
