Abstract:

To satisfy the demands for cheaper and environment-friendly aero-engines of future aircraft, intercooled recuperated cycle has been given much attention to in the past few years. Research on intercoolers and recuperators in aero-engines has become one of the key factors restricting the development of aero-engines that utilizing intercooled recuperated cycle. Research background of intercooled recuperated aero-engines is briefly introduced. Studies on heat transfer surfaces of intercoolers and recuperators in intercooled recuperated aero-engine both home and abroad are reviewed, as well as research on optimization of heat exchangers, installation and use of intercoolers and recuperators in intercooled recuperated aero-engines and the development of new type of high temperature heat exchanger technologies. Future research on intercoolers and recuperators in intercooled recuperated aero-engines is also proposed.

Key words: aero-engines, intercoolers, recuperators, enhanced heat transfer, high temperature heat exchanger, printed circuit heat exchanger, micro channel heat exchanger
