Boeing says the side-of-body modification for the Dreamliner is “on track”, but is still not disclosing any details. In a statement released Oct. 16, Scott Fancher, general manager of the Dreamliner program, said:
“The design of the side-of-body solution is on track. Installations of the fittings are proceeding well and we are pleased with the progress we are making on this important effort. We continue to be on track to fly the 787 by the end of the year.”
Boeing said a more detailed update will be provided on Oct. 21 during Boeing’s third-quarter earnings call. The original design put too much stress on composite sections of the wing, causing them to delaminate.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
SpaceX has 3D printed and successfully hot-fired a SuperDraco engine chamber made of Inconel, a high-performance superalloy, using direct metal laser sintering (DMLS). The company's first 3D-printed rocket engine part, a main oxidizer valve body for the Falcon 9 rocket, launched in January and is now qualified on all Falcon 9 flights.
Lawrence Livermore National Laboratory and MIT have 3D-printed a new class of metamaterials that are both exceptionally light and have exceptional strength and stiffness. The new metamaterials maintain a nearly constant stiffness per unit of mass density, over three orders of magnitude.
Smart composites that let the material's structural health be monitored automatically and continuously are getting closer to reality. R&D partners in an EU-sponsored project have demonstrated what they say is the first complete, miniaturized, fiber-optic sensor system entirely embedded inside a fiber-reinforced composite.
