MAV
is designed for 50 minute endurance, and can take off and land in
wind speed conditions up to 15 knots and fly a mission under wind
speed of up to 20 knots, as well as under rain conditions. Service
ceiling is 10,000 ft. The vehicle usually operates at altitudes
of 100 to 500 feet above ground level, and can provide forward and
down-looking day or night video or still imagery. The vehicle will
operate in a variety of weather conditions including rain and moderate
winds. The MAV uses a small gasoline powered piston engine, driving
a counter-rotating ducted fan system. Although the MAV can be quite
noisy at close quarters, it is virtually inaudible (60 dBA) at a
distance of 100 meters. Steering is performed by flat deflectors
controlled by the automatic pilot, which rotate the cylindrical
vehicle to the required direction to point the payload at the target,
and develop forward thrust for lateral movement and acceleration.
An alternative propulsion system using a micro-turbine, is under
development at Locust USA. The current version is consuming slightly
more fuel than the piston engine powering the MAV, but is considerably
more powerful. A future version of a reciprocating turbine will
improve fuel consumption to improve mission endurance and payload
capacity.
MAV carries its sensors and datalink in a pod mounted on one side
of the vehicle, counter-balanced by the avionics and control pod
on the other side. Payloads include a forward and downward looking
EO and IR imaging sensors, capable of detecting and recognizing
a man-sized target at 250 meters during daylight (125 m at night).
Based on its own position and measuring of payload aiming angles,
the payload can also extract the coordinates of the target, at a
target location error (TLE) of 20 meter. The interchangeable pod
uses modular design, accommodating other sensors according to the
mission requirement. The MAV is controlled via tough tablet computer
converted into a ground control station with an integrated video
recorder storing up to 60 minutes of sensor imagery. Operating modes
include autonomous flight via dynamic re-tasking and manual intervention,
hover and stare and remote launch modes. The system stores up to
100 waypoints in a flight plan. Up to 10 flight plans can be stored
on the ground station.
Miniature
Turbine Powerplant for the MAV
Locust USA, producers of a family of miniature turbine engines
designed for mini UAVs. The company developed several turbines delivering
from 5 to 150 shp,
One of the applications of this micro-turbine offers an alternative
propulsion system for the Miniature Aerial Vehicle (MAV) Class I
UAV developed by Honeywell. Using a micro-turbine, the current version
is consuming slightly more fuel than the piston engine powering
the MAV but is considerably more powerful. A future version of a
reciprocating turbine will improve fuel consumption to improve mission
endurance and payload capacity.
