Inlet Design Inlet Design MSI1993 (Aerospace) (OP) 11 Mar 16 21:04 For a Ramjet, how to decide what angle to use for the inlet cone? RE: Inlet Design rb1957 (Aerospace) 11 Mar 16 21:59 Mach number maybe ? another day in paradise, or is paradise one day closer ? RE: Inlet Design WKTaylor (Aeronautics) 14 Mar 16 15:54 MSI1993... This topic might get more response in the Aerodynamic Engineering Forum http://www.eng-tips.com/threadminder.cfm?pid=1 NOTE. AIAA Aerospace AIAA Education Series [texts] include some excellent books on engine-airframe integration and engine-inlet design. http://arc.aiaa.org/series/4.es?_ga=1.194199144.49...

[Picasso] RE: Inlet Design KENAT (Mechanical) 14 Mar 16 19:19 Simplistically it's related to target mach number as rb1957 suggests. However, if memory serves what's really important would be angle between tip of the cone and the lip of the duct - ie. the effective angle.
