Abstract:
The essence of dynamic combustion was explained. Based on the requirements of both military and civil aircraft engines, the importance of conducting dynamic combustion technologies and supporting the optimization design of aero-engine combustors was highlighted. The research progress on dynamic combustion technologies was summarized and compared from domestic and foreign aspects in terms of fundamental research, model combustor research, numerical simulation, and engineering application. The challenges in developing dynamic combustion technologies were analyzed, four key technologies to be developed in China were presented, and their connotation and technical pathways were expounded. Based on the design requirements of advanced engines along with current dynamic combustion progress, suggestions including establishing database, developing design methods, building theoretical system and training research teams, were put forward for developing dynamic combustion technologies in China.
