The invention discloses a liquid ramjet engine fuel supply gear adjusting device. The device is composed of internal oil supply pipelines distributed in an oil supply pipeline integration module, external oil supply pipelines, oil supply on-off solenoid valves, a main oil supply pipeline, an oil pump, an engine oil supply pipeline and an experimental engine through connection, the n internal oil supply pipelines are distributed in the oil supply pipeline integration module, one side of the oil supply pipeline integration module is connected with the external oil supply pipelines, one side of each internal oil supply pipeline is connected with the corresponding one external oil supply pipeline, the internal oil supply pipelines are gathered through the other side of the oil supply pipelineintegration module to be connected with the engine oil supply pipeline, the experimental engine is connected with the engine oil supply pipeline, the corresponding oil supply on-off solenoid valve isinstalled on each external oil supply pipeline, the oil supply on-off solenoid valves are consistent with the external oil supply pipelines in number, and the external oil supply pipelines are connected with the oil pump through the main oil supply pipeline. The device solves the problem that the flow of a scramjet engine fuel supply device cannot be accurately adjusted according to gears.
Description
technical field [0001] The invention belongs to the field of liquid ramjet connecting tube experiments, in particular to a liquid ramjet fuel supply gear adjusting device. Background technique [0002] Experimental research on scramjet engines began at the beginning of this century. Xiao Baoguo et al. mentioned a fuel supply method in "Scramjet Combustion Mode Conversion Direct-Connected Experimental Research", which can complete the flight under the condition of Mach number 4.5. The experimental research on the combustion characteristics of the engine can measure the engine operating parameters, but the engine fuel supply device cannot realize the precise adjustment of the fuel according to the gear position, and cannot accurately evaluate the impact of the sudden change of the engine fuel flow on the engine performance during the experiment. Li Dapeng mentioned a fuel supply device in the article "Research on the Working Process of the Combustion Chamber of Kerosene Dual-m...
