Hopefully
it won’t happen very often, but when Amazon and others finally get fully
fledged drone delivery services off the ground, there’ll be occasions
when the flying machines suddenly drop out of the sky.
Whether
it’s inclement weather, a software malfunction, or some ne’er-do-well with a
catapult and a rock, we have to accept that those multi-copter contraptions
will sometimes get into difficulties and fall all the way back to the ground.
It’s
one of several challenges that gives the Federal Aviation Administration folks
sleepless nights as they consider the safest way to let companies and
organizations use the popular technology as part of their operations.
But
Amazon may have the answer.
The
online shopping giant is exploring an innovative system that would cause an
airborne drone that’s in difficulties to disintegrate in mid-air, minimizing
the force of the potential impact on any human, animal, or object on the
ground.
The
idea is outlined in a patent granted this week by the U.S. Patent and
Trademark Office. Titled “direct fragmentation for unmanned airborne vehicles
(UAVs),” the document describes how a malfunctioning drone could dismantle
itself in the sky after assessing the conditions on the ground.
“The
fragmentation sequence includes a release timing and a release location to
fragment away (e.g., release, drop, jettison, eject, etc. away) one or more UAV
components in case the flight operation of the UAV is disrupted,” the company
says in the patent.

Conditions
that could cause problems for a delivery drone are listed as “unexpected heat,
cold, wind, rain, hail, high or low (e.g., barometric) pressure regions, or
other meteorological conditions.” These could affect the drone’s rotor system,
flight control computer, battery, flight sensors, or other components,
resulting in a major malfunction that makes it behave more like a brick than an
aircraft.
The
patent, which Amazon filed in June 2016, says that the release system could
include “attachment mechanisms, such as clips, latches, hooks.”
Amazon
says the fragmentation sequence would happen automatically, and that depending
on which parts of the drone are jettisoned, “the weight, speed, air drag
coefficient, and other factors related to the UAV can be altered.” This
suggests that the drone wouldn’t always completely disintegrate.
Rather, it would in some situations only eject the parts causing the problem if
it allowed the damaged drone to make a safer landing.
We’re
assuming the system would also do its best to ensure that whatever it’s
carrying — several textbooks for a delivery, for example — is jettisoned away
from anyone its sensors detect on the ground … providing it’s not its sensors
that are malfunctioning.
It’s
an intriguing idea, though Amazon has been filing a lot of intriguing ideas
related to its delivery drone ambitions, some more outlandish than
others. Check out this city-based drone tower that would look — and
sound — like a giant beehive. And if you want to go full bonkers, then this
patent for a “flying warehouse” should tickle you.
There’s
no telling whether this latest idea will become a thing, but it nevertheless
offers some interesting insight into how champions of the technology are hoping
to overcome the great challenges that lie ahead.
