Abstract

The invention relates to the technical field of engines, in particular to a system of recycling wasteheat of an aero-engine. The system of recycling the wasteheat of the aero-engine comprises the aero-engine, a thermo-acoustic engine and a heat carrying fluid pipeline. A part of the heat carrying fluid pipeline and a housing of the aero-engine are arranged in a fit manner, and the two ends of theheat carrying fluid pipeline are correspondingly connected to a heat carrying fluid inlet and a heat carrying fluid outlet of the thermo-acoustic engine. The system of recycling the wasteheat of the aero-engine provided by the invention can drive the thermo-acoustic engine to work by mean of heat transferred to the housing by air flow in the aero-engine so as to convert heat energy into mechanicalenergy, so that heat when the aero-engine works is recovered and the energy utilization ratio of the aero-engine is improved, and meanwhile, the gas quantity loss for cooling the housing of the aero-engine is reduced, the cooling problem of the aero-engine is solved effectively, the integral performance of the aero-engine is improved, and the system meets different demands of an aircraft.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an aeroengine waste heat recovery and utilization system. Background technique [0002] The aero engine is the heart of the aircraft, providing power for the entire aircraft. However, the thermal efficiency of current aero-engines is very low due to the high temperature of the exhaust heat. When the aeroengine is working, the airflow entering the aeroengine inlet is mainly divided into two parts after being compressed and boosted by the intake compression section, one part enters the combustion section, and the other part enters the shell interlayer of the engine as a cooling airflow. After the airflow entering the combustion section burns and expands in the combustion section, it pushes the expansion turbine in the expansion section to do work, and accelerates into the afterburner, where it further burns with the injected fuel to raise its temperature, and accelerates the injec...
