1. Study of air intake configuration Presented by Chirag.D.soni Airplanes may kill you but they ain't likely to hurt you. — 'Satchel' (Leroy Robert) Paige, baseball player, circa 1959.

3. What is air intake? In any application subsonic transport or supersonic fighter the air intake is essentially a fluid flow duct whose task is to process the airflow in a way that ensures the engines functions properly to generate thrust

7. Turboprop engine air intake

9. Bifurcated intakes

11. NACA submerged inlet in a euro fighter The NACA submerged type intake is not very efficient for use with propulsion installations. However, they are frequently used as intakes of auxiliary systems (auxiliary power unit, heating and avionics bay cooling) as seen in Fig above

12. Intake flow field

15. Pressure recovery and nose suction formation

19. Various types of supersonic inlets

20. Flow conditions over wedge and cone In the design of supersonic air intakes flow conditions over wedge and cone are of the greatest importance as these are simple geometric bodies and relatively easy to manufacture.

26. Oblique shock diffuser intake characteristics

27. Examples of use off oblique shock diffusers Mirage ||| fighter with side mounted oblique-shock diffuser Two dimensional oblique shock diffuser (Northrop F-5 with vertical ramp)

28. Axisymmetric oblique-shock diffuser (Lockheed SR-71 )

32. F-14 intake characteristics
