Abstract

The invention discloses an injection system based on mixed reaction of two-component liquid fuel, and relates to the technical field of scramjet engines. The injection system comprises an injection panel group, a first fuel control system and a second fuel control system, and the injection panel group is connected with the first fuel control system and the second fuel control system; the injection panel group is configured to enable first liquid fuel and second liquid fuel which are injected into the injection panel group to be rapidly mixed and efficiently react, and meanwhile, high heat released after the reaction of the first liquid fuel and the second liquid fuel and generated intermediate active substances are injected into a combustion chamber; the ignition reaction of a scramjet engine is realized when the scramjet engine flies under the condition of the low Mach number (the Mach number is less than 4.0); and the first liquid fuel is a boron-containing complex, and the second liquid fuel is unsaturated hydrocarbon. The system is simple in structure, safe and efficient, and the problem that the scramjet engine is not prone to ignition under the low Mach number condition is solved.

Description

technical field [0001] The invention relates to the technical field of scramjet engines, in particular to an injection system based on the mixed reaction of two-component liquid fuels. Background technique [0002] A scramjet is a ramjet in which fuel is burned in a supersonic airflow. When using hydrocarbon fuel, the flight Mach number of the scramjet engine is below 8. Because the scramjet works in the supersonic airflow, it can obtain oxygen from the atmosphere during the ascent process, giving up carrying oxidant, and has the advantages of simple structure, light weight and low cost. [0003] But it can't start automatically in static state, and it can work effectively after it must be pushed to a certain speed with a booster method, and its low-speed performance is not good. Reliable ignition and efficient combustion of hydrocarbon fuels remain a challenge, especially in scramjet combustors flying at low Mach numbers (Mach numbers < 4.0). The total temperature of ...
