Much like the US aerospace industry, Russia's has produced a massive amount of vaporware in the last twenty years. I did not believe this one would ever make the pad much less be ready to fly in the next 60 days. This rocket will replace Proton and will likely launch the next-generation Russian capsule which may have seating for twelve! The test flights will be over the next 5 years at which time Proton will be retired.

For those of you wondering, in nominal 1/64 scale, core and boosters (for the Russians, first and second stages) are all identical and would be Series 18 tubing. The third stage would be BT-70 and the payload fairing would be BT-80. Gonna need some custom Sandman cones for the boosters, transitions and the fairing.

I'm gonna need to go roll a Jiffy-Mart to pay for this one.


I have a request in already for Angara part.
Mark, I don't know if it was you... I have trouble with real names/forum names.

Unfortunately I really don't have a really good profile pic of the parts.

I'm working on the scale drawings so I can make the parts.

Gordy,

It was not I asking for Angara parts. But I'm in if you are producing stuff. Try this link:

http://www.russianspaceweb.com/angara5_flight1.html

That's as good as you're going to get. There maybe more pictures coming in over the next few weeks as the Russians are still saying launch before the end of the year. This rollout was for system and pad integration tests. Note that the core and boosters appear identical up to the end of the long conduit.

I started working on measurements and the aeroshroud top is almost exactly a Vostok-style cone. As I noted, I'm thinking ST-18 boosters and core; BT-70 Third stage and BT-80 fourth stage and aeroshroud. So that's 4 booster nose cones, two transitions and fairly large cone. What size were you contacted about making?

For what it's worth (I don't know) there's a downloadable paper model of the Angara 5 here: http://www.cardmodels-r.narod.ru/ht...ngara5-rev1.pdf

Spasibo ("Thanks"), Rich! Its blunt biconical nose cone is strongly reminiscent of the Russian Dnepr SLV's (SS-18 ICBM's) similar nose fairing. That Angara model should fly fine, if made of 110# cardstock, glued together securely, and sprayed with clear lacquer to further stiffen the cardstock and make it moisture-resistant.

Maybe not (although clear plastic fins would provide an easier solution). Scale models of rockets with strap-on boosters can sometimes be persuaded to fly straight by adding nose ballast, which facilitates the boosters' serving as crude but effective fins. Also:

Another option (but one that likely wouldn't lend itself well to cardstock rockets) is to "install" well-concealed air intake vents in the body, and to install the motor way up front, *inside* the body, with the recovery system above it. This allows the motor exhaust, mixed with entrained air that comes in through the vents, to be exhausted out the rear of the body, which serves as a "3-D" 'skyrocket trailing stick' for stability.

Ok, this is what I've tried to interpret from the pictures.

I just edited the parts, I had the boosters too large.

For the booster tubes, I used BT-60's. Scaled to the Series 18 and BT-70 it would call for a 1.54" body tube.
The closest to that size is the BT-60 at 0.1" larger in diameter.

Comments, criticisms, corrections?

Cool, but there's another transition from the core to the third stage. Remember the core and the boosters are all the same diameter and the third and fourth stages are different diameters, with the tird stage being smaller in diameter than the fourth (only in Russia).

When I look at it the short straight section you have on the booster cones it seems to me to be slightly tapered. This short segment will also be slightly tapered on the transition from core to third stage and then flare out for a sort-of truncated hourglass shape on that piece.

I wish I could draw this but I'm at work . . . .

When you get home scribble me a sketch of what you mean on the taper.

Now when I look really really close I can "kinda" see the second transition.

Then I looked at an Angara 2 picture the second transition is clear. That would be a Series 18 to BT-60 transition.

I'll wait until I hear back from you with your sketch before I change my drawing.
