Research & Development
JAXA promotes three research and development programs and a fundamental research program that underpins them.
With supersonic civil transport such as the Concorde, it is said that a 1% increase in air resistance will eliminate the capacity sufficient to carry three passengers. Air resistance has a profound influence on fuel consumption.
In NEXST-1 (small supersonic experimental plane), the aircraft configuration was designed so that fuel consumption would be improved. An important hurdle for the realization of supersonic civil transport, economic efficiency, and therefore better fuel consumption efficiency was demonstrated using flight experiments.
The "NEXST-1" flight experiments took place in 2002 and 2005 at Woomera experimental yard, Australia, achieving air resistance reduction of as much as 13% compared with that of the Concorde.
