Electric X-Plane Nears Crucial Battery Test

Quote
NASA is preparing to test a redesigned lithium-ion battery module for its first electric propulsion demonstrator, the X-57 Maxwell, as it moves toward a maiden flight planned for early in 2018. The ground test will replicate one performed in December that resulted in a destructive thermal runaway and required the packaging to be redesigned. That test involved deliberately initiating a short circuit in one battery cell to ensure the overheating did not spread to other cells—but it ...

Success With Low-Boom X-plane Critical To NASA’s Aeronautics Vision

Quote
We may not recall them all, but those we do remember hold special places in aviation history. The X-1 in which Chuck Yeager broke the sound barrier in 1947. The X-15 in which Pete Knight reached Mach 6.7 in 1967. The X-43 that hit Mach 9.6 on scramjet power in 2004. They are the X-planes. Aviation afficionados will recall even more: the X-5 that pioneered variable wing sweep, the X-24 lifting bodies, forward-swept-wing X-29 and thrust-vectoring X-31—the international X-plane. Then ...
