Abstract

The invention discloses a low-temperature self-ignition adjustment method for liquid hydrocarbon fuels based on atomic carriers, and relates to the field of aviation fuels. Through the atomic carrier additive, the combustion energy barrier of the base fuel is reduced, and low-temperature self-ignition of the hydrocarbon fuel is realized; the atomic carrier additive is a borane dimethyl sulfide complex; the base fuel is octene, hexene or olefin and RP ‑3 Blended fuel with kerosene. The invention has the advantages of real-time regulation and control of ignition, low self-ignition temperature, strong safety, etc., can realize high-efficiency regulation and control of the low-temperature self-ignition combustion characteristics of the liquid hydrocarbon fuel, and has simple operation and strong practicability.

Description

technical field [0001] The invention relates to the field of aviation fuels, in particular to an atomic carrier-based low-temperature self-ignition regulation method for liquid hydrocarbon fuels. Background technique [0002] Aeroengines will stall in the air due to compressor surge and other accidents. Compared with ground ignition, the air temperature at the engine inlet is lower (inlet temperature <-40°C) and pressure is lower (0.3 atmospheres) during air ignition. Under such harsh working conditions, how to achieve reliable ignition of the main combustion chamber and stable flame propagation is the main technical difficulty faced in the design and use of the main combustion chamber of advanced aero-engines, which restricts the development of advanced aero-engines. Aiming at the ignition problem under severe working conditions faced by advanced aero-engines, it can be seen from relevant research reports at home and abroad that the influence of key parameters on the ign...
