The principal requirements of combustors for advanced

high-tech aircraft engines are reviewed in this paper. Key technologies are briefly described and new development approaches are introduced.Combustors will be developed continuously in the direction of improving performances

shortening length

increasing reliability and durability

reducing exhausting gas pollution

and utilizing alternating fuels

the last one is the key to the success of wide application of industrial gas turbines.Various new combustor concepts are in study both abroad and home

includingdouble-annular combustors

vorbix

axially or radially stagged combustors

varying geometry combustors

twin recirculation combustors

horse shoe combustordome

vortex buring afterburner

barchane dune flame-holder and so on. Among the key technologies for advanced combustors

improving spray quality and combustor-dome fuel-air mixture preparation

and developing advanced coolingschemes and heat-resisting materials are in the first priorities.Rapid progress of computer and laser technologies strongly influences a varietyof science and technology fields

combustor is no exception. The main aspects of computer modeling and laser diagnostics of combustion processes are briefed

and a new empirical/multidimensional analytical design methodology is surveyed

which is believed to become a new approach to studying

designing and developing advanced combustors.
