I may be crazy, Has anyone tried this?

[Zetoyoc]

Am I out of my mind. I recently came across an unlabled picture of a missile I just love the look of.

(the top one)


after some searching I could not find that particular missile unfortunatly but found some similar.








I'm certain it would have to be a scratch build and may be beyond my current skills. But I may have to give it a go anyway.

Has anyone built this missile or have information on dimentions or can convince me I am crazy and should upscale an alpha instead.

Check out wiki first-- it's an Italian design--anti ship--Quite a few sights under otomat

[Disaster_Guy]

Looks somewhat similar to the ALARM (anti-radiation missile). http://en.wikipedia.org/wiki/ALARM

EDIT:
Never mind... thought you were talking about the middle one.

[Zetoyoc]

I think i'm going to research and attempt to build the melera version. or a crazy mix of the two, or .. good thing this is the research phase.. gulp..

got kind of a harpoon look to it..sadly I lost mine,was one of my nicer builds

Did you ever try this? It's on my short list - I've had a couple of illustrations bouncing around my folder of projects since 2008-2009 while I was looking for Harpoon data. I've got a small Harpoon kit I'm going to try to convert to a 2 stage LPR, but I'm just itching to make the OTO-Melara MILAS. With the Anti-Submarine torpedo on the front it looks more likely to be dynamically stable, and as a bonus you could make the whole torpedo component eject for recovery. (You can see the torpedo in the line drawings at the bottom of your last illustration. It is one bad-*** looking rocket at launch, though (http://upload.wikimedia.org/wikipedi...T-84-03922.jpg). Boost with two side engines, sustain with main? (I'm kidding!!! or am I...)

Jesse,

As a USAF Aircraft Mechanic (Retired) - I too have a love for the models that resemble or are replicas (scale or sport) of the real thing ............... DO IT Take your time and make the model you want.
I am going to work (one day) on a Nike Ajax model since I have a real one in the museum right down the street....... I can measure and take pics .. the whole nine yards !!

I'm more of a civilian aficionado, but for some reason I really dig the harpoon and otomat. A couple years ago I built a Pegasus based on a 2.6" frame and subbed a 29mm mount for the kit's 3x24mm. Easily the most complex and challenging "kit" I've built. Flew it naked (up to first full finish coat, no stickers) and watched in horror as the bottom rail button caught at the top of the rail, flipped the bird horizontal, and - on F power - flew straight and stable with wings flat and tail up for a good 600+ feet about 30' off the ground...directly into a heavy stand of trees. I got most of the parts back.

I didn't know about the rail button problem until later. We figured it was an odd stability issue until I found the rail button at the bottom of the rail later that day and matched it to the missing button on the model. I haven't built another scale model since - just not enough time.

[JordanT]

Okay...first step is seeing if it can be scaled. Turns out the program I use for marking up engineering prints (Bluebeam Revu, a PDF program) will re-scale noted dimensions on the fly. I give it a desired dimension, tell it what I want it to scale to on the print, and it recalculates. A few minutes and I came up with this:

[Rocketbuilder]

For some reason, the PDF you posted won't open for me. Has anyone else had problems with it?
JordanT, what diameter did you scale it to?
Thanks

[DizWolf]

Opened for me just fine.

[[POW]Eagle159]

Wow thats cool!

Looks too complicated for me though!

[cwbullet]

Neat missile, but complicated build. I always wanted to build an ALCM cruise missile, but everything I think of it, I talk myself out of it.

[JordanT]

I had two choices...BT60 or 3" for the main body, resulting in either a 24" or 45" tall model, respectively. I opted for 3". It makes the torpedo a touch bigger than a BT-80/2.56 LOC tube. My biggest worry is the air intakes at the main fins. They look like half of an ellipse that gets crushed at the rear. I don't have any good photos straight on from the front, and the side views are blocked by the SRBs, though the lines drawing at the bottom of the linked image in an early post shows the missile rotated 90 degrees and the weird trace the back of the intake. Next up is a RockSim model to see how much play I have in engine weight, how carefully I have to keep an eye on mass distribution/CG, and if I have to sport-model the fins to make it stable.

If/when I get past that stage, I'll probably make a new thread in the scale area.

Here's a screen capture of the dimensioned drawing for those who couldn't see the pdf. Of course, the fin depths still have to be scaled by 1/cos(45), or 1.41 to account for the rotation of the image.

[Rocketbuilder]

Awesome, thanks! Even though I'll be building it in a different scale (BT-55, since I've got tons of it) those dimensions give me somewhere to start.

[JordanT]

Well, the more the merrier. Here's a re-scale with the rear tube as a 1.325OD:



No sense in burning up a calculator when a single dimension regeneration will do it!

[Rocketbuilder]

Wow, thanks again! I can't wait to get started on this. Unfortunately (from a rocket-building standpoint only, of course ), I'm going on a two week vacation in a few days, so I probably wont get started until I get back. And then there's school, which will further limit the amount of time I have to build... But I'll get it done eventually. The big question is how much detail I can/am willing to put into it.
Once my computer is back from the shop (the computer I'm on right now won't run OR, it's too old), I'll draw up an OR file, to see if the top one can be built to true scale. If it can, it will definitely need lots of noseweight, but probably not so much that an F39 won't lift it; I'm willing to sacrifice altitude for accuracy, anyway.
Should be fun!
