    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.


    Thanks for your reply.

    Purely aerodynamic (?) or partially aerodynamic roll control can be feasible for the first stage of Angara-1.2, for example. However, the Angara-5's core is mostly a 2nd stage rocket block. I doubt that aerodynamic control would be useful regarding the Angara-5's core's flight profile.

    Additionally, Angara-1.2, etc. probably only use supplemental aerodynamic roll control during the early stages of their flight when, due to the larger moment of inertia of the launchers around the roll axis at the early stages of their flight, the Angara-1.2 type optimally small thrust-based roll control system is not sufficient. Under this scenario, the question still is where the roll control thrusters on Angara-1.2, etc. are.

    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.
    https://www.youtube.com/watch?v=BsQOpD4TIZM

    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!

    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

    You can clearly see the rocket deform in the video. This deformation has nothing to do with "veering" and is a pure lense distortion.
    Just let it go.

    ok, it was within launch parameters ,payload entered Gso so success.
    then briz-m fired last time its fuel reserve ,and took itself and dummy payload still together, from busy geosynchronus -to higher graveyard orbit.
    here is a comparison to its competitor.
    http://en.wikipedia.org/wiki/Delta_IV_Heavy

    unfortunately no angara 7 ,which would overtake delta ,for next few years.

    The A5 is already superior to the heavy Deltas, there really isn't a need for an A7 as of now. Now that the Angara project has proven (so far) successful, I think the RSA will put more time into other projects along with the Angara.

    delta is pure hydrogen /oxygen propulsion, angara uses kerosine as fuel in 1st and 2nd core stage, and briz in 3rd stage. it would need hydrogen /oxygen in 3rd stage to get more lifting power an that engine- kvtk is not ready in next few years.

    If you go to the wiki or elsewhere they do not bother to adjust for latitude of the launch site when listing rocket
    payload to different orbits. The Delta Heavy has more payload to GTO capacity but a lot of that is due to the
    fact it is being launched from Cape Canaveral while the Angara is launched from Plesetsk.

    The A5 can be modified to have the same nominal payload performance as the Delta Heavy by giving it a LOX/H2
    third stage.

    so where can it be looked up -the payload weight depending on different launch sites , plesetsk ,vostochni ,and equatorial - brazil- alcantara perhaps.

    production issues are not settled so there will be logistics and production rate problems. many factoried are in european part or urals , only omsk factory is in western siberia.
    that makes vostochny very far away from manufacturing facilities.
    only 1 launch in 2015...meh No
    i think angara -1.1 will replace zenit and that would be best to destroy ukraine capability and revenue , plus pick up ukranian pro-russian engineers and staff and continue wtih 100% russian product + profit.

    I can see what you mean.. the light deviation to the right of the head.. but it can be an effect of the lens of the camera.. Because if you look at the tower ,the steel structure that hold firm the rocket.. it also appears to be not aligned too.. and this is before the rocket is launched.. but no idea really .. could be a problem that happened or could be a camera lens effect what we saw.

    I actually notice the launch pad incredibly close to the rocket.. that tower so close to the rocket does not inspire me confidence.. could get stuck with the rocket.

    Any rocket launch is a balancing act, so sideways movement of the nose, especially at launch is just as normal as the flapping of the horizontal stabiliser on an aircraft with FBW flight controls on landing or take off.

    It doesn't indicate a problem, it is just a natural settling of control.

    i dont think you can compare a space rocket to an airplane. but lets put this question to rest.

    i dont think you can compare a space rocket to an airplane. but lets put this question to rest.

    They are very comparable... it is just that the tail surface of an aircraft is more visible than the tiny variations in thrust and thrust angles of the various rockets keeping a rocket vertical as it leaves its mounting.

    At lift off there is a critical period where the air is not flowing rapidly down the sides of a rocket, so balance is what keeps the nose pointing upwards... at launch the only think maintaining that balance once it is no longer supported on the launch pad is the directed thrust from the rocket motors.

    It is rapidly burning fuel which shifts the cg, so it is natural for there to be a bit of wobble at the start.

    so for the whole 2015 no angara launch .,like i said production is going to be problematic , even launch was problematic it seems.

    You do realise the Angara is a family of launch vehicles and they are talking about 2016 for the next launch of the heavy weight model that takes payloads into geostationary orbits from Russian launch pads...

    There is no mention of launch or production problems in that article....

    Thats not news, has to do with schedule conceived a while ago.

    And the launch was flawless by all reports.

    1 angara launch was planned in 2015,
    but this year is full of rocket launches near 40 are planned, next year less- about 30 and simmilar 2017 , so in 2016 ,2017 there should be spare capacity left from factories and bureaus.

    Russia's Angara rocket program funding not to be cut despite economic crisis — source

    The Angara rocket family is a new generation of space launch vehicles based on a universal rocket module with oxygen-kerosene engines.

    MOSCOW, March 2. /TASS/. The financing of the program for the creation of the Angara family carrier rockets will be continued in full despite the country’s current economic hardships, a rocket and space industry source told TASS on Monday.

    "The country’s financial-economic hardships will not affect the Angara program in any way. There will be no budget cuts and no additional funding is required. The money is available," the source said.

    According to him, "it’s all about the industry resources."

    The Angara rocket family is a new generation of space launch vehicles based on a universal rocket module with oxygen-kerosene engines. The family load capacity ranges from 1.5 to 25 tons. The carrier rockets of the Angara family are intended to replace the Proton carrier rockets.
