Experimental small-thrust rocket engines developed at Reshetnev University in Krasnoyarsk have successfully passed firing tests in Moscow. The tests were conducted at the stand of the M.V. Keldysh State Scientific Center (part of the Roscosmos State Corporation).
The educational institution explained that the uniqueness of the engines lies in the manufacture of combustion chambers entirely on a printer using additive technologies (3D printing) from a heat-resistant powder alloy.
Professor of the Department of Engines Vladimir Nazarov explained that successful engine tests open up prospects for creating installations operating on gaseous fuel.
These are engines for light-class launch vehicles, upper stages, correction and braking systems of spacecraft.
During the tests, three successful engine starts were performed with a duration of 30 to 60 seconds. According to visual inspection using an endoscope, no structural damage was detected.
