tomcatfan Posted August 1, 2017 Share Posted August 1, 2017 (edited) Hello folks, I am working on a F/A-18E Super Hornet that I will display as a jet getting ready for the catapult lunch. Seems like there is some kind of air intake opened on top of the fuselage just in front of the ECS Exhaust. What is this and can anybody provide detailed photographs? I feel like I need to modify this on my Hasegawas Hornet to make it look right. Any help will be very much appreciated. Best Regards, Daniel Edited August 1, 2017 by tomcatfan better picture Quote Link to post Share on other sites
USAFsparkchaser Posted August 2, 2017 Share Posted August 2, 2017 I think they are ram air scoops for the primary heat exchanger. It cools the engine bleed air for the Environmental control system. They are open when the engines are at a lower RPM and close at higher RPM. Not sure if you are familiar with the F-15E, which has the same concept on the side of the CFT. I was Air Force and worked this system. Not sure how NAVAIR works, but would think they would close somewhat while on a catapault launch as the engines go to a higher RPM or N2 which I think is the correct term for engine RPM. Hope this helps. Quote Link to post Share on other sites
tomcatfan Posted August 3, 2017 Author Share Posted August 3, 2017 Thanks for the input. From the pictures I found on navy.mil the ram air scoops seem to open almost all the time one the ground, even during take off and sometimes even during flight. Does anybody have a good detail shot?

fasteagle12 Posted August 3, 2017 Share Posted August 3, 2017 Seems like someone should make aftermarket replacement parts for them to show them in the raised position. I'm surprised no one has (hint, hint steel beach ) Quote Link to post Share on other sites
Darren Roberts Posted August 3, 2017 Share Posted August 3, 2017 Hmmm!!!!! I just need some detail shots and I'll do it. Quote Link to post Share on other sites

Well, looks like no one has any detail shots?! So I guess I will just have to make up some details. I think it will still look more realistic for my diorama than leaving the fuselage as is.

fasteagle12 Posted August 5, 2017 Share Posted August 5, 2017 I looked around and couldn't find any super detail photos. I found a couple that, when enlarged, give some detail, but not all that great. Here's one: http://www.navy.mil/management/photodb/photos/170518-N-PF593-011.JPG As you said, if no one can find detail photos, then do the smaller details make that much difference? Maybe Jake Melampy's Super Hornet guide has photos (I wish I had the book, but don't). Quote Link to post Share on other sites

tomcatfan Posted August 5, 2017 Author Share Posted August 5, 2017 too bad I missed out on that book Quote Link to post Share on other sites
fasteagle12 Posted August 5, 2017 Share Posted August 5, 2017 Here's a photo, when enlarged, gives a little more detail... http://www.seaforces.org/usnair/VFA/VFA-143_DAT/VFA-143-Pukin-Dogs-038.jpg Quote Link to post Share on other sites
tomcatfan Posted August 8, 2017 Author Share Posted August 8, 2017 very helpful picture, thanks a lot. Looks like there is an hydraulic actuator on the outside of the intake. Will try and scratchbuild that. Quote Link to post Share on other sites
