A review of research on intercoolers and recuperators in aero-engines

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.
