patchfree a écrit:Mais on voit que quand même c'est une autre fusée, par bien des aspects nouvelle, parce qu'au fond le premier (ou le second si on veux en référence à la soyouz classique) est totalement nouveau mis à part les points d'encrage... Il y aura quand même des risques lors du premier lancement.

08.09.2012 / 00:05 Central Design Bureau "Progress" expects that the launch of "Soyuz-2.1V" will be on time

Central Design Bureau "Progress" expects that the accident, which occurred during ground tests of the first stage of the new rocket "Soyuz-2.1V" will not affect the launch date of the first instance of the rocket, said Friday the company official representative Julia Izyumova.
"Experts TsSKB" Progress "will do everything possible to launch rocket" Soyuz-2.1V "took place in a timely manner," - she said.
Izyumova recalled that the launch of the first flight of the new instance, is planned for the fourth quarter of 2012, RIA Novosti reported.

Peut-être pourront-ils refaire un essai rapidement en "menant au galop", la réparation du banc d'essai, et la disponibilité d'un premier étage ?????
Et si l'essai est concluant ... le lancement peut s'enchainer assez rapidement puisque le lanceur opérationnel est prêt.
Mais tu a raison .... cela mérite confirmation.

The new missile carrier light class "Soyuz-2.1V" will be launched in April 2013 with the cosmodrome "Plesetsk
The new missile carrier light class

BERLIN, Sept. 12. (ARMS-TASS). The new missile carrier light class "Soyuz-2.1V" will be launched in April 2013 from the Plesetsk cosmodrome. This korr.ARMS-TASS at the International Aviation and Space Show, first deputy general designer Samara "TsSKB Progress" Alexander watchman.

Resolution on the first launch of a new launch vehicle will be obtained only after the Scientific Research Centre of the rocket and space industry (Relight) will be re-ground test firing of the first stage, called the "burned in" missiles ", said the representative of" TsSKB -Progress. During the test of the first stage on the ground stand the center Aug. 16 accident. Steering motor stage moved to a freelance operation, which led to its destruction, partial damage of the first stage and the cable systems that connect to the test stage. In this case, the central engine NK-33 from the experts did not have any complaints. According to experts, the cause of the accident are errors in the safety system control motor.

Thus, the delay of the first launch rocket "Soyuz-2.1V" is about four months. Earlier, representatives of the company after the accident reported that the first rocket launch will take place in due time - in the fourth quarter of 2012

With an easy two-step "Soyuz-2.1V" from Plesetsk can be run on low circular orbit spacecraft weighing up to 2.8 tons Using the unit at start removing the "Volga" rocket will remove the sun-sinohronnye orbit satellites weighing up to 1.4 tons

This modification of the carrier rocket "Soyuz" will use standardized with the variants launch system and management system. Likely that this rocket will be taken as a basis for "Soyuz-2-3." If proven and commissioning of "Soyuz-2.1V" will compete with such carriers as a Russian "Angara-1" and the French "Vega".

patchfree a écrit:
... Alors c'est vrai que le problème semble provenir du software du banc d'essai... mais bon, ça me paraîtrait risqué de lancer sans le test au sol...

nikolai39 a écrit:Là, le NK-33A (dérivé du NK-15 de la N1) n'a eu aucun soucis. Le problème vient des automatismes du banc d'essais IS-102, qui ont envoyé des ordres incorrects suite à un défaut de fonctionnement du moteur RD-0110R.

patchfree a écrit:Le problème est donc bien dû à un problème du banc de test: l'anomalie du RD-110R n'est qu'une mauvaise lecture du nombre de tour de la turbo-pompe par le logiciel de contrôle qui croyant à une vitesse excessive aurait dû couper les 2 moteurs mais n'a coupé que le RD-110R et non le NK-33 qui ensuite a fonctionné à vide et à été détruit.

Correct?

Soyuz-2.1v launch vehicle has been brought back to MIK-317/14-3 on 11st september, and it has been disassembled on 12nd september.

It will be keeped there in containers to allow the assembly of the next Soyuz-2.1b.

Et ce cher M. Pillet s'excuse d'avoir oublié de prévenir son forum préféré en premier... :oops:

In JSC "NPO Energomash" held the next firing test rocket engines

19/10/2012 ::

        October 16 at a scientific test complex of JSC "NPO Energomash" without removal from the stand held the fifth fire test experimental oxygen-kerosene rocket engine for the first stages of launch vehicles such as Russian rocket "Soyuz" and foreign launch vehicles.
        Engine, equipped with a large number of extra dimensions vibration stress state, ripple and temperature in all five tests worked 678 seconds.
        Tests carried out successfully completed the first phase of an experimental validation of a new modification of oxygen-kerosene rocket engine to be created on the basis of technology and development experience RD191 engine. The new engine, which has 200 ton thrust of the Earth, is different from the basic design of the introduction of a number of welds (cameras with a stator turbine mixing head with a gas generator housing), Fixed Mount the motor to the rocket or a cardan joint for rocking the entire engine for thrust vector control, depending the design of the rocket.
         Unlike RD191 new engine is shorter in height by 760 mm and lighter by 300 kg.
         It is assumed that the experimental engine will form the basis for the RD193 engine I stage rocket "Soyuz-2.1V" light class and other possible modifications of "Soyuz" and RD181 engine for stage I of foreign launch vehicles.
        In addition, the pilot engine program, agreed with the SRC FSUE "Keldysh Research Center", verify that the task was to design the modes corresponding to the system requirements MRKS (Reusable Space Rocket System), developed under the Federal Space programs.
        Currently under test analysis. The engine will be disassembled and thoroughly prodefektirovan. According to the results of fault detection will be decided on the possibility of further tests and adjustments in design and technological solutions.

01.11.2012 / 12:51 Running light rocket "Soyuz-2.1V" is scheduled for March-April 2013


The first launch of a new carrier rocket "Soyuz-2.1V", together with a new block removal "Volga" is planned for March-April 2013, as a payload considered satellite MSU "Lomonosov", or created by students Samara apparatus "Stork", RIA a source in the space industry.
The first launch of "Soyuz-2.1V" from Plesetsk was originally scheduled for October. However, after an accident during tests of the rocket engine in the Moscow Research Center aerospace industry (SIC PSC), which occurred in August, the launch was postponed.
