Next Generation Rocket Angara: News

I find shocking the level of incompetence of Russian Government in promoting their space program . You have here
bran new next generation heavy rocket angara 5  being launched successfully and not a single video anywhere in
any Russian media of major event. How can they expect to attract investors to Russia if they don't advertise
their nation capabilities.

So you have an interesting situation in Russia ..where not only the western media have done a good job , in brainwashing people that Russia innovate nothing and is only a gas station.. but also Russian  media incompetence
in to properly promote any new technology  or machine they create.

SImply Russia government is not very efficient in advertising its own industry. RT for example is highly view in the west.. but they do not take advantage of their media success in promoting either Tourism or foreign investments
in Russia.

And for a good reason...
THERE WAS ALMOST A DISASTER AT TAKE-OFF.

You can see the top of the missile veering to the right side, but then correction from thrust vector engines kicked in and corrected so the launcher got straighten out. here is the video from previous poster.

Obviously some of the engines didnt got to 100% power in time, the time from engine start to launch buildin arm swinging back is too short ,and launching in mid winter when it was very cold and snow adding weight to missile, plus with cross winds , just goes to show how crazy or confident russians were to get the launch done before 2015 , probably an order from the top brass!

Does everybody think what I am thinking of?

Here's the best picture I have of the tail section of the Angara-1.2PP. Interesting.

Roll control... Do you mean the "tails"? - Which are, AFAIK, only installed on the 1.2PP. 

?

A little bit of elaboration on my previous post:

- Angara-5 core has no roll control tail surfaces.
- They say it uses thrusters for roll control.
- I am not sure if I see two thrusters or four. Whether there are two thrusters or four thrusters, they are positioned asymmetrically. (Correction: I can't count any roll control nozzles on the core. I have a suspicion where they have to be.)
- Ignoring hidden aspects of the design, the asymetrical positioning of roll thrusters is "wasteful".
- If the Angara-5 core can use roll control thrusters for roll control, why did Angara-1.2PP and Naro-1 needed roll control tail surfaces. Is it just because of the fact that the Angara-5 core at separation is lighter and has a lower moment of inertia around the roll axis, having already burned some of its propellants, than Angara-1.2PP at launch with full tanks? What other reason can there be?
- How about Angara-7? It's core surely would't fire before separation; so it would even be heavier and with a larger moment of inertia around the roll axis than Angara-1.2PP at launch.
- Very interesting.

- How about Angara-7? It's core surely would't fire before separation (Correction: It probably would fire a split second before separation to obviate any need for any separate ullage handling mechanism.); so it would even be heavier and with a larger moment of inertia around the roll axis than Angara-1.2PP at launch.

- Very interesting.

Can someone find, possibly through Russian language sources, some answers to the questions that I raised in my previous post?

Thanks.

I have no sources and I doubt they exist aside from blogger speculation.

It looks to me like all the engines are used to control any roll.   One of the pluses of having thrust vectoring ability (albeit limited).

Before the separation of the strap-ons (blocks A, B, V, G), the strap-ons perform the roll control. The question relates to the phase after the separation of strap-ons.

We do not see if the inner section deploys winglets so I would not rule that out.

That veering to the right side is clearly a distortion effect of the fish-eye lens being used to film the launch.  You do
not see any veering in the part of the video filmed without a distorted view.

it depends on viewers angle, form 90degree view no side veering you wont notice it , but in paralel viewing camera you could see at 8-9 sec some tilting of the top of the rocket to right side. something like this https://www.youtube.com/watch?v=tvNALouyQaI
