FIELD: motors and pumps. ^ SUBSTANCE: inventions are referred to rocket engineering, namely to elimination of rocket engine solid fuel charge on a test bench equipped with localisation, cooling and neutralisation chamber for combustion products (LCNC). Determination and monitoring of various process parameters including combined steam gas flow rate measurement in combustion products is required to solve a number of problems related to charge elimination in solid fuel-operating rocket engine on test benches equipped with LCNC sections. The inventions for combined steam gas flow rate measurement in combustion products ensure reliability and validity of data to be acquired under complicated conditions of semi-closed LCNC spaces, where high-speed, high temperature steam gas flow of combustion products is remotely monitored. The initial rate of combined steam and gas flow as well as rate dynamics during the whole process is monitored and measured by means of this method and telescopic module. It allows for determining optimal process modes (especially amount of the supplied cooling agent, hydraulic parameters, changing conditions of combustion products outflow rate, etc) ensuring rocket engine charge elimination safety on test benches equipped with LCNC sections. ^ EFFECT: process safety of rocket engine charge elimination on test benches equipped with LCNC sections. ^ 2 cl, 6 dwg |
