Early B-52G/H radome

Hi Nigel,

 

I'm wondering though if you also compared the kits in your video to actual line drawings or only compared them to each other.

 

Thanks,

 

Marc.

 

Hi Marc,

 

To answer your question.. in a word..No. I don't have reliable line drawings, and I don't trust drawings unless I KNOW they're good.

 

I think we can sum this one up with what "looks" right, to my eye the Revellogram kit is spot on, the others are, well, wrong.

Thanks for that. I'm not crazy about Vallejo, but with paint that's often a touch personal. I might go for a home brew on the basis of Gunze or Tamiya.

 

Yeah having tried several paints I keep going back to the old faithfulls like Tamiya and Gunze for aircraft too but the colours Vallejo put out are compelling.

Just to keep you interested.. I thought I'd pop up a pic of the Master in progress for the Italeri/AMT H with EW gear. Upper ECM has been mastered with its mounting flange and is currently being moulded.

 

If you compare this to the kit parts you'll see a big difference.. especially the profile underneath..

 

The resin parts will include the radome including underbelly and cooling vents forward of side ECM's , ECM (Either as one with nose or separate)?

 

I think I will also make separate FLIR blisters as the AMT ones are so bad.. in fact the MC ones are poor as well... 

 

I'm also working on the MC nose, which is very labour intensive!! I've had to replace pretty much the whole fuselage under and forward of the glazing. Once the later (Phase VI) radomes are done I'll get stuck into the early nose.Is that phase IV?

 

Please let me know what you think.. good or bad.

Makes sense to me.

Yeah,

 

Phase IV (4) consisted among other things of:

  • AN/ALR 20 countermeasures
  • AN/APR 25 RHAW
  • AN/ALR 18 receivers
  • AN/ANT 6B or 22 CW jammers
  • AN/ALT 13 jammers
  • AN/ALT 15H jammers
  • AN/ALt 15L jammers
  • AN/ALT 16 (you guessed it) jammers
  • AN/ALE 20 flare dispensers
  • AN/ALE 24 chaff dispensers
  • AN/ALE 25 chaff dispensers

HTH.

 

Marc.

How do you determine drawings are "good" (accurate) ?

Sorry Marc, you may as well write that in double dutch.. it all means nothing to me!!

 

Can you describe the phases by visual changes to the radome please.

Opinion among those in the know or blueprints. otherwise I just use them to look at.

 

For example.. I consider any drawing other than blueprint to be an artists representation at best, unless a renowned expert on the subject says otherwise. Also, as with the Squadron signal B-52 in action book.. there are 3 view drawings and artists colour drawings.. they all have errors which could cause the modeller to make shape errors. Just look at the shape of the wing tanks in that book if you have it.

I have posted this in the "H" thread, but wanted to put it here as well to ensure all interested parties see it.

 

Here's a pic of where I am now. Ignore the Flir on the belly, I haven't made the non flir belly yet.. just look at the MC stock nose in the background!!

 

Edit: looking at this picture I am wondering if there was another radome, or if the profile of the early nose above on the station diagrams is incorrect? The nose I have roughly carved to shape here looks a little too sloped to me, but it perfectly matches the profile above.?? So.. could it be we have the long "EVS" nose, two interim G/H short noses and the shorty D nose?

Post here for the sake of duplication....

 

This may help...or not... (posted under "Fair Use" for educational purposes)

It looks to me that the Later nose has more of a up sweep and it approaches the end of the radome. The early seems to me more gradual. 

The later nose doe have a more "pointy" appearance. The early nose is "pointy" but not at the same angle as the later nose.

The nose you just carved looks to me closer to an A through F model nose rather than an early G/H nose.  Just my opinion and derived purely from looking at your photo.

I think it's established there are (at least) three nose types:

  • pre G model
  • pre phase IV - just kidding VI
  • from phase VI

From phase VI top and bottom profile are markedly different. I would say the change below starts from the pressure bulkhead at station 345.50.

Where can i find information on how to identify the phases of B-52 upgrades? I keep reading about Phase IV or phase VI but don't really know what it refers to?

 

I have all the better known books.. so a reference to them would be cool.

Hi Nigel,

 

Very helpful for me is the Aerofax Datagragh book by Dennis Jenkins and Brian Rogers.

 

The pictures Steve posted are also from that book.

 

Further, Steve, Dutch and Teeradj were very useful in determining whether indeed there was a different nose contour or not which a month or so ago was still pretty much in the air.

 

Let me know if you're in a rush, then I can send you relevant pages via mail.

 

I also have the HPH kit which I think is stunning (unlike their customer service which is very underwhelming). I'm half planing to backdate the kit to a Chrome Dome era H but I'm not sure if I've got the bottle for that. Steve's station diagrams were very helpful in that respect but I really need some cross sectionals also.

 

Let me know if I can help further, happy to share the book with you - internet prices for this book are somewhat silly.

 

Marc.

I disagree Marc.. The change is from 175.6, the back end of the composite belly. A change from 345.5 would have entailed a complete re-design-remake of the lower ejection doors and all surrounding structural members. I firmly believe the changes made to all fuselage variants from A-H are limited to removable parts such as the radome or tail gun housing.

I appreciate there was a structure added below the cockpit to replace the rear end of the "belly" on later aircraft, but that was an addition, not a change to existing structures,

 

Someone once told me they believed the AMT skinny fuselage was correct, because when they took the Man out of the tail it didn't need to be so wide...  Are there people who actually believe the engineers would have copped up a complete rear fuselage and make it skinnier just because there's no Man in the back now???

I have that book Marc, so references to where to look for the info will be great...Thanks

Look on pages 28 and 32 of the Aerofax data graph book for an explanation  of the different Panasonic EW upgrades.

I’m not buying the 3 different nose radome theory. Talking to former BUFF guys, guys that were around from the 60s to the 80s don’t recall 3. Different noses, only two: pre and post EVS.

Hi Steve,

 

The three noses include the original nose as worn very nicely by the D version amongst others.

Steve is correct in his statement. I was pondering the idea of three noses, basically because the station diagram above shows an early configuration and is a little too sloped, more like a cross between a D and a G.

 

So, yes there were three styles/shapes, but i was suggesting there may be four in total. I am incorrect in my assumption.

My attempt here is to backdate my very nice HPH 1/48 BUFF into a SAC bird. 

 

Slowly but surely reliable information seems to be surfacing.

 

 

 

I'm considering making a mould of the 1/48 nose then making a resin copy to cut up and cast an early nose for that one too.
