Supersonic intake
WebMar 1, 2024 · The adopted intake is designed to ensure an efficient functioning, not only in nominal conditions but along the supersonic ascent trajectory thanks to a movable inner spike. A nonzero angle of attack resulted in a little degradation of the performances in terms of efficiency, spillage, and flow distortion. WebIntake is an important component of next generation air-breathing engines such as Ram/Scram jet engines, as well as conventional jet-propulsion systems. The super-sonic intake decelerates compresses the air inflow by shocks or compression waves to appropriate flow conditions for a specific engine system. The performance of su-

A diverterless supersonic inlet (DSI) is a type of jet engine air intake used by some modern combat aircraft to control air flow into their engines. It consists of a "bump" and a forward-swept inlet cowl, which work together to divert boundary layer airflow away from the aircraft's engine. This eliminates the need for a … See more 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 … See more The DSI bump functions as a compression surface and creates a pressure distribution that prevents the majority of the boundary layer … See more Weight and complexity reduction Traditional aircraft inlets contain many heavy moving parts. In comparison, DSI eliminates all moving parts, which makes it far less complex … See more • "JSF Diverterless Supersonic Inlet" - Code One magazine, Lockheed Martin • • University presentation on JSF Program • F-35 Technology page Archived 2012-05-06 at the Wayback Machine See more 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.

Bleed has been efficiently used in supersonic and hypersonic intakes for three primary reasons: to improve the performance of the intake, to reduce the starting Mach number of the intake, and to postpone the onset of buzz oscillations.
WebMar 19, 2024 · A diverterless supersonic intake consists of a three-dimensional bump and a forward swept cowl lip. The bump serves the dual purpose of external compression as well as diversion of low energy boundary layer developed on the fuselage. The boundary layer is diverted by the combined action of bump and forward swept cowl.
