October 16 scientific test complex of JSC "NPO Energomash" without removal from the stand held the fifth fire test of the experimental oxygen-kerosene rocket engine for the first stages of launch vehicles such as Russian rocket "Soyuz" and foreign launch vehicles.
The engine equipped with a large number of extra dimensions vibration state of stress and temperature fluctuations in the course of the five tests worked for 678 seconds.
Tests carried out successfully completed the first phase of the experimental confirmation of performance of a new modification of oxygen-kerosene rocket engine, developed from the technology and experience in the development RD191 engine. The new engine, which has 200 ton thrust at the Earth, differs 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 to the rocket engine mount or a universal 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 easier nearly 300 kg.
It is assumed that the experimental engine RD193 engine will form the basis for the I-stage rocket "Soyuz-2.1V" easy class and other possible modifications "Soyuz" and RD181 engine for stage I of foreign launch vehicles.
In addition, the pilot engine program agreed with the SSC FSUE "Keldysh Research Center", the problem was solved verify that the design on the modes corresponding to the system requirements MRCA (Reusable Space Rocket System), developed under the Federal Space program.
Currently conducted analysis of test results. The engine will be disassembled and thoroughly prodefektirovan. According to repair a decision on the possibility of further tests and adjustments to the design and technological solutions.
