The invention discloses an aero-engine fuel combustion characteristic experiment detection system. The system comprises a fuel oil system, an air inlet system, a combustion system and a data samplingand detection system. The fuel oil system is used for providing flow-controllable vaporized fuel oil for the combustion system; the air inlet system is used for providing main combustion air and cooling air for the combustion system; the combustion system is used for providing a limited space with controllable combustion pressure for combustion of fuel oil; and the data sampling and detecting system is used for detecting, sampling and measuring combustion data of the combustion system. According to the invention, combustion in a turbulent flow state can be realized, and the obtained ignition and combustion characteristics of the fuel contain the influence of turbulence and are closer to actual situations; and the system has a real aero-engine combustion head, can cover the actual working conditions of an aero-engine, can directly obtain enough data matched with the actual working conditions of the aero-engine, can supplement detection standard parameters of the aero-fuel ignition and combustion characteristics, and is simple, easy to implement and low in cost.
Description
technical field [0001] The invention relates to the technical field of engineering thermophysics and combustion technology, in particular to an experimental detection system for fuel combustion characteristics of an aero-engine. Background technique [0002] With the development of the aviation industry, the requirements for the combustion performance of aero-engine fuel are increasing, so it is necessary to study the ignition and combustion characteristics of aviation fuel. Some existing technologies can detect the ignition and combustion characteristics of fuel. For example, experimental devices such as fast presses and shock tubes can be used to measure the ignition delay of fuel. However, these detection methods cannot consider the influence of turbulent flow on the ignition and combustion characteristics of fuel, and cannot cover the actual working conditions of aero-engines. Large, the obtained data does not match the actual working conditions and can only be used as ...
