Abstract: We present a new mathematical model for startup of staged liquid rocket engines (LRE). It is based on the improving the mathematical models of low-frequency dynamics of cavitating pumps and gas LRE channels as well as on the introducing the process of injecting gaseous oxygen into the liquid oxygen stream in the LRE feed. We describe a mathematical simulation of the l startup of the prospective sustainer LRE of 250 ton-force thrust, which is being developed at the SE "Yuzhnoye" Design Office (Dnipro, Ukraine).
