amurray Posted March 13 Author Share Posted March 13 7 hours ago, Derek B said: Hi Art, Good images from Carsten. Looks like the auxiliary bypass slots are covered over by spring loaded doors, and not plated as I originally thought. I could not find any really good images of the intake boundary layer outlets, however, given the angles of these upper and lower outlets, it would strongly suggest that the internal boundary layer splitter must be bifurcated in some manner? How this would look configuration-wise is anyone's guess, as it looks like it is part of the internal fuselage structure (you would need copies of the original Hawker drawings or a detailed aircraft repair manual to determine this). It has been an interesting education for me, which will help me later with my own model. Good luck Art. Derek Derek, I really appreciate your efforts and hope I can return the favor some day. If ONLY we had an ex-Hunter ground crew member in our group! I found a website of a group in CA and VA that supposedly has 20 Hunters in service. I'll call them to see if I can be put through to someone on their grounds crew. https://www.atacusa.com/mk-58-hawker-hunter Derek B 1 Link to comment Share on other sites More sharing options...
amurray Posted March 13 Author Share Posted March 13 "In for a dime, in for a dollar!" While I'm at it I might as well detail the automatic air bleed ducts and doors. Sometimes they are open in flight, other times not. Sometimes they are open while taxiing, other times not. Derek B 1 Link to comment Share on other sites More sharing options...
Smeds Posted March 14 Share Posted March 14 I am an ex Armourer, I worked on Hunters F.6, FGA.9 and T.7's at RAF Brawdy in the early 80's. The doors just aft of the intakes were spring loaded. The ground crews used them to secure canvas FOD covers in place with bungee's. Derek B 1 Link to comment Share on other sites More sharing options...

They are well documented. I need the structure of the boundary layer air ducts. Many thanks. Derek B and Smeds 2 Link to comment Share on other sites More sharing options...
amurray Posted Saturday at 01:41 AM Author Share Posted Saturday at 01:41 AM Kopecky Scale Models flare dispensers roughed in. EXCELLENT resin pieces! I didn't have to reshape the kit pieces as much as I feared. Air bleed duct cut outs started. I'm not going to open the doors on the wing surface because the design of the wing is such that it would be very difficult. But one will be able to see the ducts in the air intake. The doors were open in very few photos, so IMO I'm on solid ground. The ducts are visible in the air intakes.

amurray Posted Saturday at 11:39 PM Author Share Posted Saturday at 11:39 PM Well, I finally got my answer on the boundary air layer duct. It penetrates the wing but NOT the intake. That means I have to go back to patch the intake openings I made for the boundary air layer ducts. Also, trashing the intake splitter was a bit of a mistake but it is misshapen and my change to its profile is more accurate. AARRGHH!!!

Derek's excellent close-up photos of the air intakes above show the automatic air bleed ducts but not boundary layer air ducts opening into the air intakes. Understand that I am solely going on the basis of the knowledge of others. I have zero firsthand knowledge of this aircraft. I consulted the head of the F-35 structures engineering group and separately a career Naval Aviator.
