NewGuy here, so let the Fun begin, eh? ;D I'm building Revell's Six (1/48) of a 5th FIS Dart. I always build planes in-flight; in this case I want the bay open and the IR head extended......... After much searching, I came across one pic of a plane under test with the ball extended, but nowhere near clean enough for scaling, even with some SuperGeek enhancing of the image. Where can you get any data/pics on the IR seeker system? I could do a hack job with a ball bearing on a dowel or somesuch, but.......NO! There must be some info somewhere. Help! (pleeeeeze?)

( pleeeeeze? ) Hi Rattinox, I Googled "F-106 IR seeker head" and found no images. There are some low res pics of the IR head extended in these books: Page 49 Convair F-106 Delta Dart by William G. Holder Aero Series # 27 ISBN 0-8168-0600-4 Page 6 f-106 DELTA DART IN ACTION by Captain Don Carson & Lou Drendel Squadron/Signal Pubs ISBN 0-89747-014-1 Page 75 (cutaway drawing) Wings of Fame Volume 12 (softback edition) ISBN 1-86184-021-7 I'd estimate the ball was 8-9 inches in diameter or about the size of the pilots head without helmet. At 1/72 scale that would be about 1/8 inch or slightly less so a B-B might do the trick or a ball bearing. The head looked chrome in color with a blueish tint. Hope this helps. Pat Perry 456th FIS

Pat Perry 456th FIS Woops! Since your are building a 1/48 scale, 9 inches would be 0.187 inch or 3/16 inch Pat

I once had to escort a Head to Warner Robbins for some kind of maintenance. It was if I recall a new addon for the Six. The case was huge, but as was said the unit was close to 10 inches in diameter and blueish tinted. It also had a goldish subglow in direct sunlight. If I recall the air deflection platform just forward on the Six was black and angled slightly upward to the ball. Maybe some former Six Jock migh have more on it for us. Speak up guys.

The IR head and system was an ADD-on TCTO and the area where the head was located was faired into the fuselage.....The head was liquid nitrogen cooled and the door('s ?) were air operated and the head was electically driven.....The head was constructed like the IR head on the Falcon missiles.......If your model doesn't have the HUMP on top of the nose just ahead of the windshield, I would suggest that you forget that modification.........Trivia question : What was the vapor that came out of the vent when the nitrogen system was being serviced? ?? ::)The Old Sarge

Cold nitrogen vapor untill the system was full,then it started spitting liquid nitrogen. Yep, til it condensed the oxygen in the air and it became liquid, and when it came in contact with greasey,oily gloves it became 100% gaseous oxygen and on one instance at Loring, the glove burst into flames........Thus the reason for the catch can when servicing the nitrogen system........Good to see you back Bien....

Thanks to all for your info. I've never seen anybody try this modeling stunt (seeker extended); so even if crude it's a try at least...... I worked as a lab tech for an optics firm that did alot of IR detector stuff. One of the more important things we developed was the canopy-darkening system to protect the pilot's eyes from a nearby nuc flash......(ooops! could I be shot for blabbing this?!). The huge carrying case protecting the head was very necessary. Those detectors were fantastically fragile- I know! The weird coloration on the ball is multiple layers of micro-thin metals like gold, tantalum, etc. that screened out all but the specified IR rays. I've watched many a time as these metals were vacuum-deposited on the latest (mid-eighties) prototype detector was coated- incredibly beautiful stuff..... Alas, I'm worse than any wannabe pilot. I got booted from The Academy for.........Hay Fever! Stinking alergies! "We can't have xxxxxxxx sneezin' pilots, xxxxxx Johnson!" Never lie to Uncle Samuel.......... Thanks! P.S. The liquid nitrogen was to get the detector as cold as possible for maximum sensitivity. Since IR is basically heat radiation............. Thank God I never had to deal much with that stuff. One good blast from a bottle would freeze your hand to the bone instantly. Fingers would crack off like bad marble; nobody in our shop got The Freeze, thankfully................

The glass was actually pretty thick, around 5/8" or so. All Ruby Glass and not at all see-thru for human eyes.
Along around 82 or 83, they went to electronic cooling and did away with the nitrogen altogether. After that it could "see" vacuum tubes at tempature. No longer needed a lit cig for a target.
Who remembers the goofy test cap for the seeker head? Gave it a pinpoint target to look at, but nothing it could actually track. Of course, SP's took care of that chore, and when the radome was off, you could slave the radar dish to the ir head, lots of fun that was...

On the AIM-9 they are using Argon to cool the seeker head. It's stored in a small bottle in the guidance section. I forget how much pressure is in it but 5000 psi rings a bell.

;D I snoozed, I loosed! I haven't been on the Board for awhile and missed the new posts.
Those vids of the Dart & seeker head have been removed "due to use violations"........
Are there any other references?
(I'm doing a Dart from the 11th FIS/Duluth in 1/48th scale in the act of firing a nuclear Genie)

:smokin: Well, looks like Old Man Reality isn't the curmudgeon I always thought he was........
I did a new search on "F-106 cockpit" and was rewarded with a gorgeous shot of the IR seeker!
Too bad I can't figure out how to upload the thing........

Here it is: A far better link: flickr.com/photos/dodzq1ozz/2565643769/And if that doesn't work, just do a Google search for "F-106 cockpit" images The pic will be on a Flickr file on the second page. You cannot miss seeing this shot! It's glorious . Wonder how the guy got this pic? And where?!

You cannot miss seeing this shot! It's glorious . Wonder how the guy got this pic? And where?! Hi Ratt, Great find! Here's a copy of the image in case anyone has any trouble getting to the site. Looks like ertoss lives in the Delaware area. I left a message to see where and how he took the photo. Here's another link to the Flickr Military Aviation section. There are over 31,000 photos there! flickr.com/groups/military-aviation-photography/Just click on the first image and you go into a slide show. Or just fan through the pages until you see something you want to enlarge. Thanks for the heads-up Ratt, Pat P. 456th FIS
