Orbital Sciences GCM-163 Coyote

[sambatterman]

Does anyone have any scale plans/drawings/dimensions on the Coyote sea-skimming cruise missile/drone?

When you go to the Raytheon site, the Coyote doesn't look like the one you pictured.

Raytheon seems to make a completely different missile named Coyote. The GCM163 is Northrop Grumman: https://news.northropgrumman.com/ne...n-achieves-100th-coyote-target-vehicle-launch (picture shows a booster, apparently, but the sustainer looks like the above pic)

Okay - let me be super clear - I like the Orbital Science version. That's what I want to build. Any thoughts? Thanks for helping me here hobie1dog and neil_w.

 

[Hobie1dog]

Length	5.60 m (18 ft 4.3 in) (without booster) 9.53 m (31 ft 3.3 in) (incl. booster)
Diameter	35 cm (13.8 in); booster: 46 cm (18 in)
Weight	?
Speed	Mach 2.8
Range	110 km (60 nm)
Propulsion	Booster: Hercules MK 70 solid-fueled rocket Sustainer: Aerojet MARC-R-282 solid-fueled ducted rocket/ramjet

Just to be even superer clearer - Orbital Science = Northrop Grumman.

Anyway, I do not see any obvious source for scale plans, however I did find this: https://itsablast.com/store/orbital-sciences-gqm-163-coyote-details.html. They have a cardstock model of the missile, may or may not be accurate. Apart from downloading the plans and gleaning what you can from there, you might try contacting the people who run that site and see if they'll tell you if *they* had an source for drawings or plans, or if they just went off pictures (which is sometimes the only way).

 

[Hobie1dog]

the above was from this site which you may have already been to:

Thanks guys!
Thinking roughly half scale would be 9'2" tall and 6" Blue Tube - that gets it close.

It wouldn't surprise me if the actual drawings and plans are classified.

Their public affairs office gave me grief like I was going to poach their contracts when I asked for data. I even specified *exterior dimensions* and that I didn't care about the internals. email me later (phlash1-at-gmail-dot-com) and I'll send you a link to my dropbox folder. I'm not even sure what I've got in there - it may all be stuff you've already accrued....

 

[neil_w]

I had similar difficulties when building my IRIS-T. The manufacturer would not give me the time of day. Eventually I just collected as many pictures as I could and took measurements off them. Good enough for a sport-scale build.

This guy has already flown one at LDRS-40. there are 4 pictures but I cannot save them for some reason, but you can click on the right arrow and see them all:

appears to be a 4 inch version

 

[Hobie1dog]

I sent the guy a message on Reddit, so we will see if can give us the information.

 

[sambatterman]

Thanks so much guys - this is very helpful.

I think I'm most concerned/interested in the air scoop/inlets - everything else is very straightforward. There is a lot of detail and "section-ality" of these inlets that are not captured in just a straight "box" approach.

ACME Aerospace is the Prime. You might talk to them.

 

[rharshberger]

Mac Performance offered their version of this missle at one point iirc, I know you are a scratch builder so that may not be something within your interest.

Thanks - I was just using that picture to begin to determine placement and size of the fairings, fins and guidance strakes.

Just an aside to the OP...

Until this post, I never made the connection between the Coyote and Estes QCC Explorer. Good pic on TRF (Here). Mine has been in pre-primer stage for 2+ years. I need to finish it...
