Abstract

The invention relates to the technical field of ramjets, in particular to a device for testing fuel combustion performance of a ramjet. The device for testing the fuel combustion performance of the ramjet comprises a combustion system, a pyrolysis system and a flame data acquisition system, wherein the combustion system is used for atomizing liquid fuel, mixing the liquid fuel with gaseous fuel and igniting the mixed fuel; the pyrolysis system is communicated with the combustion system and used for providing controllable liquid fuel and gaseous fuel; the flame data acquisition system is connected with the combustion system and used for detecting the combustion performance of mixed combustion of the gaseous fuel and the liquid fuel. The device for testing the fuel combustion performance of the ramjet is mainly used for detecting the combustion performance of endothermic hydrocarbon fuel, can simulate the working state of a scramjet of a power device of a hypersonic vehicle, detects and reasonably observes the fuel combustion performance of the ramjet, can detect the combustion performance of both pyrolysis gas and the liquid fuel, and has the advantages that the device is concise and convenient to operate, the safety is high, a flame is convenient to observe and temperature measurement point positions are more flexible.

Description

technical field [0001] The invention relates to the technical field of ramjet engines, in particular to a fuel combustion performance testing device for ramjet engines. Background technique [0002] Hypersonic vehicles with a flight Mach number greater than 5 are at the forefront of the development of contemporary aerospace science and technology. As a hypersonic vehicle power plant, the ramjet requires a larger cooling heat sink due to the harsh ambient temperature. The thermal protection measures currently used routinely, such as traditional air film cooling, improved materials, and passivated cooling technologies, cannot meet the requirements for thermal management of high-temperature components of aircraft. The use of heat sinks such as mechanical refrigeration systems or non-flammable coolants can provide effective cooling, but will reduce the load performance of the aircraft. From the point of view of aircraft integrated design, combustible coolant (that is, heat-abs...
