JAXA’s research focused on both developing the advanced composite structures as well as the smart technology for this next generation of aircraft. In parallel with JAXA’s research, the TMU undertook research into likely future avionics developments.
The research involved two phases, both of which utilized HBM’s equipment for the testing regime. The first phase, which was undertaken in 2011, developed an Advanced Technology Demonstrator (ATD) as a business jet for up to 8 passengers (Fig.1).
The second phase, which took place during 2012, looked at developing a regional jet for 120 passengers. Following the success of the tests on the ATD’s canard wing (Fig.2) a bigger composite structure for a wing in the region of 5 m long was built and static tests undertaken to examine the integrity of the fuel tanks that are located in the aircraft’s main wing.
Both aircraft feature specially developed advanced carbon fiber reinforced laminates (CFRP). The high impact resistant laminates are reinforced by Vectran fiber through-the-thickness stitching to reduce any loss of structural strength through delamination.
