GBU-10, 12, Guided Intelligent Weapons

[Flite-Metal]

Has anyone developed these? There is a need...electric jet modelers are in need of light weight, detailed,
scale card stock models since weight is the major concern when they detail their projects.



The 10 and 12 are similar in shape.

That shouldn't be too hard to do. What scale? Do you have any specs?

I'll google and see what I can find.

Would something like this do? I see GBU in the description, but don't know which one they are.

John,

Its 1/9th scale. What I have in mind is creation of a wrap which can be placed over cardboard tubes of multiple diameter
like found in a toy rocket kit. Balsa noses and other items can be utilized to beef up the scale details, but at its root its a
simple, inexpensive pair of tubes.

GBU-10: 1:9 = 18.67" length x 2" dia.

GBU-12: 1:9 = 14.67" length x 1.25" dia.

GBU-24: 1:9 = 18.67" length x 2" dia.

Below is an older Estes (The toy rocket division of Hobbico) GBU-24 which is further up the evolutionary chain from
a GBU-10 or GBU-12. A market exists for this concept because of horribly expensive vacuum formed, resin, and fiber
glass components produced by two or three people. These yield too much weight and something that can not be
released from the model during scale contests if it is resin.

We fly mission plans during scale contests and scale details are reviewed and compared to documentation during static
portion of these events. Below is the Estes GBU-24 which was made in China between 2003-2005. I found one of these
this afternoon.


As you can see there is a difference across the evolution of "seeker" technology utilized in the nose to detect infrared, or radar
return since the GBU-XX was introduced. In the above image the rear fins are unfolded. A single internal spring can push to the
rear pushing on the short side of the hinged fins extending fins when GBU is dropped. A small parachute within rear between fins
can slow its descent to prevent severe damage.

I envision a plastic laminated sheet to be placed onto card board tube, balsa, plastic, etc. to create a light weight weapon.



The pylon mounts for these weapons are varied. Below I post images of a pylon rail made from balsa which was used on a model
of an A-10 Warhog. You can easily imagine designing a wrap for the multiple weapons carried by modern jet aircraft. I will post
an image of the typical A-10 as it is armed today. It is loaded for Bear...

Cool.......... but how do you want to handle the tapered ends of the MK 8X bomb?

And also you want to be able to deploy the guide fins after dropping?

Normally in geometry a domed end is comprised of multiple radians. In the art of card stock modeling that would see the domed
ends as the collection of triangle points to form a rounded shape. In addition to normal radians at the end, a taper is comprised
of radian elements as well.





There are several designs of rear elements on Iron Bombs. Rear elements that garner the geatest amount of attention are the
one's designed to "retard" the fall of the Iron Bomb enabling the jet to clear blast wave to avoid airframe concussion damage
or shrapnal.

MAU-91 "Snakeye" Bomb

Obviously, the mechanicals of the retarding function will be constructed of appropriate plastic hinged to a slip collar around the
rear shaft of the weapon. The card stock should replicate this, then it is glued to the plastic as with all elements of this so this
becomes its cosmetic skin, as if in a SIM.

Below is the MK-82 retarded tail fin mechanical layout.



Typical pylon "rail" with three MK's. There is also a four rail for some aircraft.

This image below has a lot of high contrast lighting and shows more detail of the retard mechanism. The shovel shape is apparent
in the rounded shape which wraps around bomb body. This will I believe require two card pieces to form each segment. On with a
curve, the second "back piece" is attached to curved one.

Did this help?



Below are the multiple configs of the GBU...

That one's mine.

It has 1:50 scale:
Mk 84
GBU-10
CBU-58 Cluster bomb
GBU-32 JDAM
MK-7 Nuclear bomb

Also available on another sheet is:
AGM-65 Maverick
Red Top Missile
Aim-9 Sidewinder
AIM-120 AMRAAM
AGM-45 Shrike
AIM-4 Falcon
AGM-54 Phoenix
AIM-7 Sparrow

Plus
M-157 and M-159 Rocket Pods, and M-135 Minigun.

Most of these were designed to be mounted on aircraft, so there are no deployable fins.

Flite-Metal........ check your PMs.

Playing around with Wings3D I made up this. It's just the bomb section of the MK 82.

Two "bombs" that are 6 1/2 inches long. I haven't bothered to scale them yet.

Is this what you want to start with?

I have 6 GBU-24's coming from Seattle. They were originally Estes rocket kits. I need only shorten body tube by 1" and it will be 1/9th
scale as required.

These still have a market place if anyone is game for creating them in a pdf with high enough resolution to be perfectly clear at 1/5th
scale. Yes, we have model jets that are 20% of the 1:1 Remember to create internal formers to support skins.

The MAU-91 "Snakeye" Bomb would be fabulous as a skin which could adhered to the wood and plastic parts to provide a scale image.
