[0030] S1. Weigh deionized water with a mass fraction of 70% with an analytical balance, add glycerol with a mass fraction of 15% to 25% into the deionized water, and slowly stir with a glass rod for 10 minutes;

[0031] S2, add the mass fraction of 5% to 15% hydroxyl-terminated hyperbranched polyester (HBP) into the solution, and continue to stir slowly for 10min;

[0032] S3. Put the mixed solution into an ultrasonic cleaner and shake for 30 minutes to ensure that the solution is mixed evenly, and the solution is sealed and stored.

Embodiment 3

[0034] The application of a novel hydrocarbon fuel coking inhibitor is specifically realized by the following method: a tee joint is arranged at the inlet of a high-temperature fuel cracking device of an aerospace power engine, and the fuel and the coking inhibitor are respectively added from two channels. The branch of the coking inhibitor is equipped with an electronic valve. The valve is automatically closed when the fuel cracking temperature is lower than 700 °C, and the valve is automatically opened when the fuel cracking temperature is higher than 700 °C. The coking inhibitor is added to the cracking device. Barbed wire, increasing the heat flow disturbance can ensure that the fuel and additives are mixed evenly, and the addition amount of the coking inhibitor is 5% of the fuel amount.

Description

technical field [0001] The invention relates to the field of aerospace power engines, in particular to a preparation method and application of a novel hydrocarbon fuel coking inhibitor. Background technique [0002] With the continuous increase of flight Mach number, the effective cooling of aircraft combustion chamber has become an urgent problem to be solved. Endothermic hydrocarbon fuel is used as a cooling medium for active cooling heat management due to its excellent endothermic properties, that is, before the fuel enters the combustion chamber, it flows through the micro-channels on the wall of the engine combustion chamber, passing sensible heat, latent heat of phase change ( Physical heat sink) and chemical cracking reaction endothermic (chemical heat sink) to cool the walls of the combustion chamber. However, the coking reaction occurs simultaneously during the high-temperature pyrolysis of fuel, and coking will increase the flow resistance, affect the heat transfe...
