The fire endurance test reusable rocket engine-demonstrator S5.86.1000-0 number 2 draft 7.5 ton of fuel on a pair of liquid oxygen (LCD) - Liquefied Natural Gas (LNG) has been successfully held on 28 September at booth V2A IC-106 FSE "SIC RCP" in Peresvet (Moscow region).
The rocket engine designed and manufactured in "KBhimmash them. A. Isaev, "- a branch of Federal State Unitary Enterprise" GKNPTs them. Khrunichev "on the technical task of SRC Federal State Unitary Enterprise" Keldysh Research Center. "
During the test, carried out a double integration engine. Duration of the first start was 162 seconds. On the second turn was reached a record length of the engine of such dimension with a single turn - 2007 seconds. The tests were terminated for making components.
Total flight time in this instance the engine during the 4-inclusions was 3389 seconds.
During the test confirmed the possibility of multiple (double) start and stop the engine-demonstrator at the liquefied natural gas, long the engine, made by closed circuit recovery with afterburning generating gas for fuel pair of LCD LNG stability prolonged (more than 2000 seconds) the engine demonstrator in native mode, with various combinations of thrust and fuel mixture ratio, the correct technical solutions adopted for the multiple launch, management, regulation, taking into account features liquefied natural gas, the ability to stand for the long-term tests, etc.
The tests have provided experimental data to refine the methodology for calculating the cooling of the combustion chamber when using LNG as a cooling agent. Also improved the technology of transportation, refueling and temperature control of large masses of liquefied natural gas and tested technological solutions practicable procedures for refueling flight products.
The program engine test is successful, the press service of Russian Federal Space Agency and the Research Center of the RCP
