Research Activities on Supersonic Technology at JAXA
Japan Aerospace Exploration Agency has promoted supersonic technology research including flight demonstration since 1997, in order to establish the fundamental technologies fora next generation supersonic transport. In the first program(NEXST program) from 1997 to 2005, we demonstrated the validity of the computational technology and some low drag design concepts by a flight trial of a scaled experimental airplane (the NEXST-1 vehicle), and this program was successfully terminated in 2005. The current research program, Silent Supersonic Technology Research Program(S3 Program) started in 2006 as a follow-on program of the NEXST program. The main objective of this program is to establish supersonic technologies mainly for improving environmental compatibility such as reducing sonic boom. In this program, JAXA promotes not only basic research but also flight demonstration for low sonic boom design technology. As for basic research, R&D on computational design technology, aircraft technologies for low sonic boom, low drag and lightweight, sonic boom modeling and so on are being studied. Also, a flight demonstration project, DSEND project, is planned for verifying the validity of JAXAs low sonic boom design concepts. This paper describes an overview of this program and the current research activities.
