    Subject: F-16 Inlet, part two
    --> TeamGrumman-List message posted by: Bruce Smith <bruce.smith@york.com> Gary, I read that General Dynamics designed an inlet for the F-16 that had variable geometry, for customers who may have desired a higher "dash" speed. Was this ever tested? I know that an F-16 once hit 1,600 mph. This may be too over the top, but what about a variable geometry inlet system for Grummans? Bruce Smith

    Subject: F-16 Inlet, part two
    --> TeamGrumman-List message posted by: "James Courtney" <jamey@jamescourtney.net> Wouldn't such a device be more about tuning how pressure waves build up at high subsonic and supersonic speeds rather than amount of air fed to engine as presumably at mach# speeds the engine is getting quite a bit of air. One of the MIGs (21 I think) had a movable cone in the engine (SR71 may have had this too) to allow some tuning of the supersonic airflow into the engine. If this is the case, unless you put hang a PT-6 and a JATO you're probably not going to see a benefit. Anyway, these are simply the ramblings of a software engineer and not a real engineer so I look forward to responses by those more knowledgeable:) Jamey -----Original Message----- From: owner-teamgrumman-list-server@matronics.com [mailto:owner-teamgrumman-list-server@matronics.com] On Behalf Of Bruce Smith Sent: Wednesday, August 09, 2006 5:07 AM Subject: TeamGrumman-List: F-16 Inlet, part two --> TeamGrumman-List message posted by: Bruce Smith --> <bruce.smith@york.com> Gary, I read that General Dynamics designed an inlet for the F-16 that had variable geometry, for customers who may have desired a higher "dash" speed.

    Cockpit adjustable cowl flaps, just like a Bonanza (and others)! Actually any plane that can cruise at 150 kts and needs to climb at 100 kts can use adjustable cowl flaps to both increase climb cooling and reduce cruise drag. I think closing the cowl flaps on my Bonanza at cruise speed increases the speed by about 5 mph. Quite significant.
