Abstract
As a bridge between the economy and society, air transportation plays an important role, and the aircraft engine, which is the “heart” of the aircraft, is the key to achieve all this. However, in recent years, the particulate matter emission and carbon dioxide greenhouse effect of aircraft have brought serious pollution to the world and are of great concern. Therefore, this paper will be based on the concepts of low carbon, green, energy saving, environmental protection and safety, as well as the social development requirements of carbon balance. By studying the pollution sources and elimination methods of aviation engines, further analyzing the development process of green aviation in China and the experience and inspiration of developing green aviation in Europe, the paper aims to propose innovative development ideas in the field of aviation power in order to better serve economic development and social progress.
Highlights
An aircraft engine is a highly complex and sophisticated thermal machinery, which provides the power required for the aircraft to fly
The combustion chamber is the main source of pollutant emissions from aero engines, and the harsh environment of high temperature and pressure in the combustion chamber has become a breeding ground for nitrogen oxides (NOx) instead [2]
rapid quenching-lean oil combustion (RQL): Firstly, oil-rich combustion is carried out, and a large amount of air is injected into the combustion zone, and the air is rapidly mixed with the products in the combustion zone to enter the oil-poor combustion state, reducing NOx generation
Summary
An aircraft engine is a highly complex and sophisticated thermal machinery, which provides the power required for the aircraft to fly. It is of great significance to promote national economic development and enhance national core competitiveness. It is because of the important strategic position of the aero-engine and its role in promoting national economic and scientific development that China attaches great importance to its development and has implemented a series of national major science and technology projects, which have strongly promoted the development of this field. Since the reform and opening up, China has made great progress in the production and development of advanced military engines, the development of civil engines for the domestic large passenger aircraft C919, and the development of advanced air and space power [1]
