NK-33A test firing:

I don't know Russian, but from the machine translation I can't quite get if they were testing the automatic shutdown system or they had an off nominal situation and the engine shutdown.

My Russian is a little rusty, but my translation is roughly this:

They performed the next test of the engine, this time with added systems for protection from off-nominal situations.

The goal was to test the reliability of the protection system of the rocket engine.
During the test of the NK-33A engine after reaching the maximum values of the off-nominal shutdown sensor, the control function of the engine worked on time. The engine was shutdown at the necessary moment.

The check of the engine protection systems will be continued. The next test is planned soon.

The protective system of NK-33A successfully worked

On Friday evening, the specialists of "Kuznetsov" conducted another test of NK-33A by a customer. This time - with the connected device disaster recovery stage.

Hmmm the Russians are dumping the NK-33 after Soyuz-2-1v's first few flights in favor of the RD-191 derived RD-193!? That sounds like a big change the rocket doesn't it?  ???

Conduct a new test engine NK-33A
March 30, 2013

As promised last week to test complex of "Kuznetsov" specialists of the company held a regular fire test of NK-33A. Re - the connected device emergency protection level.

This is the third acceptance testing engine NK-33A in the year. As you know, the engine is designed for the planned flight tests as part of the launch rocket "Soyuz-2-1v." The tests were on the planned scheme, the NK-33A has once again demonstrated the reliability of key characteristics. Immediately after the fire test, this engine was sent to the assembly plant for the production of the final preparations for the handover.

Recall the previous testing of the product took place March 22, 2013.

A source writing on the "Globalnaya Avantyura" forum reports that the second attempted test firing of a Soyuz-2-1v first stage at the facilities of NITs RKP in Peresvet today ended with the stage shutting down 50 seconds ahead of schedule. The problem reportedly was not with the NK-33A main engine, but with the RD-110R steering engine. This is just preliminary information, no official confirmation yet.

http://www.avanturist.org/forum/topic/101/offset/6900/

During the first test firing on 16 August last year the stage shut down less than 10 seconds into a scheduled 200 second test firing. The tail section was damaged in the incident, forcing the stage to be shipped back to TsSKB/Progress in Samara for repairs.

A contributor to the "Novosti kosmonavtiki" forum writes that the stage did shut down about 50 seconds earlier than planned (150 seconds into a scheduled 202 second burn) due to a leak in one of the propellant lines leading to the RD-110R steering engine. However, because this is a test stand version of the engine some of the connections in the propellant lines are not standard (using bolts rather than welds) and therefore the test is still considered a success.
