Muzz Posted January 20, 2015 Share Posted January 20, 2015 I'm currently building the GWH Mig-29 9-12 kit and I'm doing a Hungarian AF example. The kit comes with PE mesh grills which cover the 3 small openings immediately aft of the upper fuselage air intakes. From looking at photos of the example I'm building, the aircraft doesn't appear to have the mesh grills fitted, just the three openings with no cover. Would this be correct?

upnorth Posted January 20, 2015 Share Posted January 20, 2015 (edited) I'm currently building the GWH Mig-29 9-12 kit and I'm doing a Hungarian AF example. The kit comes with PE mesh grills which cover the 3 small openings immediately aft of the upper fuselage air intakes. From looking at photos of the example I'm building, the aircraft doesn't appear to have the mesh grills fitted, just the three openings with no cover. Would this be correct? Muzz I've seen three different variations to those intakes: the wire mesh type cover you describe, punched sheet metal covers with "gills" cut in them as well as solid covers that are spring hinged at the back of the openings and seem to suck in like the blow in doors around the Harrier's intakes. From certain angles, in flight shots of Fulcrums fitted with the solid blow in door style make it look like there are just big holes in those spots. I'm not sure what variables would dictate which would be fitted to a particular air frame though. It could be individual aircraft, specific time frame or a bit of both.

logical Posted January 20, 2015 Share Posted January 20, 2015 The gills are shut and flush when the plane is parked and powered down. They're only open when powered up. Link to comment Share on other sites More sharing options...
Westwind Posted January 20, 2015 Share Posted January 20, 2015 Hungary operated the MiG-29B-12 „Fulcrum-A“, a simplified export Version for Members of the Warsaw Pact. Those aircraft had solid blow-in doors. As logical statet correctly, they open up only, when the engines are powered up and during the start. The "normal" air intakes are closed during this proceedings by another "flap" to prevent stones and other dangerous objects from getting sucked in, since the MiG-29 sits quite low, especially when loaded with weapons and tanks. This walkaround pictures might help as reference: http://www.primeportal.net/hangar/luc_colin/mig-29_huaf_walk1.htm Link to comment Share on other sites More sharing options...
Muzz Posted January 20, 2015 Author Share Posted January 20, 2015 The openings I'm talking about are aft of the main upper fuselage intakes, think Upnorth knows the ones I'm talking about. I realise the main upper fuselage intake doors drop open when the aircraft is powered up. This photo shows the aircraft I'm doing and the 3 small openings can be seen on this powered down aircraft behind the closed main doors................. http://www.airliners.net/photo/Hungary---Air/Mikoyan-Gurevich-MiG-29B-(9-12A)/1727657/L/&sid=77956e5fb7c33bfa87f586bee9e76f74 Link to comment Share on other sites More sharing options...
Westwind Posted January 21, 2015 Share Posted January 21, 2015 Ah, these are the openings you're talking about Look at this picture: http://data.primeportal.net/hangar/luc_colin/mig-29/MiG-29%20HuAF%20011.JPG As you can see, they are covered with mesh. I don't think the Hungarians removed them deliberately on your special colours-bird. 1 Link to comment Share on other sites More sharing options...
upnorth Posted January 21, 2015 Share Posted January 21, 2015 If I had to go by photos on the net, I'd say the jet you're doing had the solid blow in doors. In this picture, if you see how the light is hitting the aircraft, I think if it had mesh screens on those openings that the light would be catching in the upper set of them and reflecting enough that you could see mesh if it was there: http://mlm-s1-p.mlstatic.com/avion-hasegawa-mig-29-hungarian-air-force-70th-anniversary-16052-MLM20113124833_062014-F.jpg net photo It's completely possible that individual aircraft had different fits in that area if Hungary took multiple deliveries of Fulcrums over time. 1 Link to comment Share on other sites More sharing options...
Muzz Posted January 21, 2015 Author Share Posted January 21, 2015 Thanks for all your assistance folks, decision made, I'm leaving the PE parts off! Muzz Link to comment Share on other sites More sharing options...

You are right, this MiG has indead the solid blow in doors in contrast to "Number 18" from my picture . Strange, to see this differences, since Hungary got all of its 28 MiG-29s in 1993. But maybe they were from different batches. Link to comment Share on other sites More sharing options...
