Keywords: next-generation sst propulsion system, nox/co2/noise reduction, espr project

ESPR program was initiated in 1999 as the successor of HYPR program by NEDO under METI budget support in order to develop necessary technologies for the next-generation SST engine. In ESPR program, CO2 reduction technologies, NOx reduction technologies and noise reduction technologies are especially focussed as environmentally compatible technologies which are critical to realize next-generation SST. Targets of the above subjects and validation methodologies are overviewed and some major topics of intermediate research results during initial three years program are reported.
