The fundamental design of a gas turbine engine is such that the air flow-rate entering its compressor is regulated by the amount of fuel burned in its combustor. For supersonic flight the air entering the inlet also has to be re… 展开

The DSI bump functions as a compression surface and creates a pressure distribution that prevents the majority of the boundary layer air from entering the inlet at speeds up to Mach 2. In essence, the DSI does away with compl… 展开

Initial research into the DSI was done by Antonio Ferri in the 1950s, and further developed & optimized by Lockheed Martin in the early 1990s using computational fluid dynamics. The first Lockheed DSI was flown on 11 Dec… 展开

Traditional aircraft inlets contain many heavy moving parts. In comparison, DSI eliminates all moving parts, which makes it far less complex and more reliable than earlier diverter-plate inlets. The removal of moving parts als… 展开
