The Kaman K-MAX
Cargo Unmanned Aircraft System (UAS) is capable of autonomous beyond line of
site (BLOS) operation both day and night (Kaman Aerospace, n.d.). Its’ primary mission forth the US military is
autonomous resupply in both hostile and non-hostile environments and the unit
can also be configured for a variety of non-military uses including fire
fighting, logging, humanitarian resupply and construction support (Lockheed
Martin, n.d.). The K-MAX is a joint
venture between Kaman Aerospace, manufacturer of the original manned K-Max heavy
lift helicopter, and Lockheed Martin which provided the mission integration,
on-board intelligence and command and control technology (Kaman, n.d.). Possessing a maximum external load capacity
of 6,855 lbs and a an external payload hook capacity of 6000 lbs, the UAS has a
range of 396.3 km with load and 494.5 km without load (Kaman, n.d.). The system is operated via a ruggedized lap
top computer which serves as the ground control station (GCS) and utilizes a
portable antennae for line of sight (LOS) operations while BLOS operations
utilize a satellite based data link (Kaman, n.d.) No additional personnel or equipment are
required to convert from LOS to BLOS operations. Each controller can command two K-MAX. Additionally, the UAS is fitted with high-resolution
video and 3D imaging to allow for precision terrain avoidance and safe landing
in challenging terrain (Lockheed Martin, n.d.).
The entire mission can be flown in a fully autonomous mode with mission
plans pre-loaded and capable of being altered or changed mid flight by the
controller or autonomously if an obstacle is detected; if desired another
ground controller can take control of the aircraft for precision landings at
the drop site, though his is not necessary and is strictly optional.
BLOS operation has
the obvious advantage of increasing available range and enabling day or night
operations in varying terrain. Threat
avoidance is significantly enhanced by the systems ability to operate at night
and with a low noise signature provided by the twin counter-rotating
intermeshing rotors and tail-rotor less design.
Provided the technology and systems are operating correctly there are no
disadvantages to BLOS operations. The
design maintains the original K-MAX’s single seat cockpit for flight in an
optionally piloted configuration and dual flight control computers provide
redundancy and additional reliability (Kaman, n.d.).
There are numerous
opportunities for commercial BLOS UAS operations. In a study focused primarily on agriculture,
forestry and energy sectors a report by Andrew Shelley Economic Consulting and
Aviation Safety Management Systems presented to the government of New
Zealand estimated that allowing BLOS operations could provide up to NZ$190
million in economic benefits (Friday Offcuts, 2015). Currently France has allowed
one company, Delair-Tech, to certify and operate a BLOS UAS, the DT-18 UAV for
BLOS operation in France (Amato, 2014).
The American distributor for Delair, Fly Terra, has been testing the
DT-18 in New York at the DUAIR test facility.
Another opportunity
for BLOS UAS is small package delivery. UAS
package delivery, being championed by companies such as Amazon (King, 2015)
would require BLOS capability to be useable in a commercial environment. Maintaining LOS operations only for a delivery
service is simply not practical. While some argue that small package delivery
via UAS is simply not practical or realistic due to fundamental logistics
issues (Wohlsen, 2014) package delivery has been tested in certain markets
overseas such as India, which has less restrictive UAS rules than the US (King,
2015) and Canada, which in 2014 approved over 1600 companies for commercial UAS
operations (Etherington, 2015). In 2014
DHL announced that it would begin autonomous, monitored BLOS delivery services
to the small island of Juist in the North Sea, upon arriving at designated landing
point a DHL driver will make the last leg of the delivery by truck (Hern, 2014). Ultimately, based on current trials and
logistics fundamentals, it would appear that BLOS capability and operation is a
necessity for successful commercial UAS package delivery operations.
