Abstract:

Focusing on the background of carbon emission reduction in the global air transport industry， this paper discusses how to develop green commercial aircraft in order to provide a reference for the low-carbon development of commercial aircraft in China. Firstly， it analyzes carbon emission reduction situation of world aviation industry and summarizes the current situation and trend of low/zero carbon development in Europe and the United States. Secondly， it analyzes the development path of new energy propulsion and related exploration work from three directions： sustainable aviation fuel （SAF）， hybrid electric propulsion， and hydrogen propulsion. Thirdly， for the future development of green commercial aircraft products， the demand analysis and the main key technologies are presented. Finally， the product development and key technology development direction of green commercial aircraft are summarized with a proposed carbon emission reduction system for commercial aircraft.
