The article deals with the diagnostics and emergency protection system (DEPS) of liquid rocket engines (LRE) and the challenges the system faces. First, we formulate the main directions of DEPS improvement and show the structure of the system, including not only the software and hardware which directly implement the fault detection and emergency protection functions, but also the system’s ancillary elements complex, making possible its setting and adjustment. Next, we propose DEPS test set-up for both the autonomous system testing, and complex testing with the protection object and the top-level control system. Moreover, we present the procedure that enables debugging of the most part of DEPS software without reference to its hardware. Finally, we evaluate the technology development results.
