JAXA's Aviation Program Group aims to build safe, environmentally-friendly domestic passenger aircraft. It is conducting research and development to establish new manufacturing techniques and cutting-edge aviation technology. The results of the group's work are greatly anticipated in the face of accelerating global warming and new environmental regulations for greenhouse-gas reduction being set by the International Civil Aviation Organization.
Other notable research being conducted by the APG is in next-generation supersonic transport, which is also being studied in the United States and Europe after the retirement of the only existing supersonic passenger aircraft, the Concorde, in 2003. Maintaining Japan's only advanced test facilities in this area, JAXA is conducting research to develop environmentally compatible supersonic transport. The results thus far have been well received by researchers within and beyond Japan.
The following is an update from the Clean Engine Team, which is working on an engine with reduced noise and harmful emissions, and the Supersonic Transport Team, which is researching aircraft that will cross the Pacific Ocean in just five hours.
