1. APID 55 VTOL Miniature UAV, Sweden UAE protects its borders
with UAV surveillance
2. Introduction The Apid 55 is a miniature vertical take-off
and landing (VTOL) unmanned aerial vehicle (UAV) system designed
and manufactured by CybAero for the United Arab Emirates Defense
Agency (UAEDA). The vehicle can perform intelligence, surveillance,
target acquisition and reconnaissance operations in hostile
environments even in adverse sight conditions. Apid 55 grew out of
an early 1990s research project run by the University of Linkoping
in Sweden. It is a fully autonomous rotary-wing UAV that is
applicable to a wide range of civil and military roles. It captures
the real time imagery or videos of the battlefield and transmits to
the GCS through a satellite communication data link with in a range
of up to 50km.
3. Design and Features Apid 55 can take-off from and land
vertically either on a runway or unprepared airstrips. It is fitted
with a four-bladed main rotor system of 3.3m-diameter, two-bladed
tail rotor system, alternators, antennas and back up power
batteries. Flying at a maximum altitude of 3,000m, the UAV can
provide its operators with real time intelligence data by executing
surveillance and reconnaissance missions over a large area. A GPS,
gyros, accelerometers, compass, infra-red altitude meter,
barometric altitude, laser scanners and stabilized cameras are also
installed in the helicopter. The aircraft can be transported on a
pick up transport vehicle.
4. Engine and Sensor The Apid 55 is powered by a single Hirith
E18H engine. The E18H is a two cylinder, two-stroke fuel injected
engine which produces 41kW of output power using gasoline as fuel.
The Apid 55 can fly at a maximum speed of 90km/h. The aircraft is
equipped with electro-optic (EO) and infra-red (IR) sensors. The EO
sensor transforms light rays into electronic signals for capturing
real time imagery or videos of the battlefield.
5. Navigation and GCS The Apid 55 can be controlled either
manually from the GCS or through autonomous mode. The helicopter
can be operated through pre-programmed waypoints, which can be
changed during flight using a graphical user interface system.
Ground control system (GCS) is designed and manufactured to
process, retrieve, store and monitor the real time imagery or
videos provided by the aircraft using a graphical user interface
(GCU). The operators residing in the GCS operate the vehicle
through payload control systems.
