Engineers at NASA Glenn are testing a new boundary layer ingesting (BLI) inlet-fan combination—the first of its kind ever to be tested. Originally conceived of as a propulsion system for generation-after-next (N+2), the BLI system could increase fuel efficiency by 4-8% more than the advanced engines airlines are beginning to use.

We know the folks at Zipline pretty well, though, and they’ve certainly made creative engineering work for them, as we saw when we visited one of their “nests” in rural Rwanda. Visual sensors on the Droid find the delivery site and check for obstacles on the way down, while the thrusters compensate for wind and movement of the parent drone.
