Boeing's 787 will be the world's first new commercial jetliner that was designed from scratch with an on-board fuel inerting system. Later this year, the FAA will require that airplane makers and airlines reduce the flammability of fuel vapors, and inerting is the only practical way of doing that.
What is inerting? How this can prevent fuel tank explosion disasters? Why boeing 787 has it… to find an answer follow the interesting link. This is a new technique that most new aircrafts will apply in the days to come…. So budding aerospace engineers, take a peek into the future…..
