AirMule Transporter UAV, Israel




Key Data


AirMule transport UAV

The AirMule is an unmanned air vehicle (UAV) designed and developed by Israel’s Urban Aeronautics to meet the requirements of the Israel Defence Forces.

The AirMule successfully completed its first phase of flight testing in January 2010. Its maiden flight, which was scheduled for April 2009, has been postponed. The aircraft is scheduled to enter service in 2014.

In June 2009, the UAV was shipped to an airstrip located in central Israel to perform a series of ground tests for hover testing.

AirMule cargo UAV variants

In January 2009, Urban Aeronautics designed a cargo variant that will be able to fly at speeds of 200 to 250kts.

Wing tunnel testing of the variant began on 7 January 2009.

AirMule transporter UAV design and development

"The AirMule is being designed for cargo transport, medical evacuation and troop supply missions."

The AirMule was developed during the war in Lebanon in 2006 as a way of transferring troops and medical equipment. The UAV can be operated in remote areas where helicopters and traditional rotorcraft cannot function.

The AirMule is being designed for cargo transport, medical evacuation and troop supply missions. The payload bays, which are being incorporated in the vehicle, will double the rescue cabin space for wounded soldiers.

Navigation

The AirMule can be controlled either manually from a ground control station (GCS) or through an autonomous mode using an automatic fly-by-wire system. The AirMule will land safely despite communication errors in the GCS.

Avionics

The UAV’s fly-by-wire can be controlled using a four-channel flight control system that depends on inertial measurements increased by a global positioning system equipped in the aircraft.

Two laser altimeters are incorporated in the vehicle to determine the height of the UAV above the ground. The aircraft is also equipped with a vane control system to produce either side force or rolling moment.

About 460 channels fitted in the aircraft send real-time data to the ground station operators thereby allowing them to track the operations of the engine and subsystems. The subsystems include three gear boxes, two main lift rotors, and three uplink and downlink communication channels.

Sensors and radars

The UAV is equipped with infrared sensors and two laser sensors for monitoring flight altitude.

The AirMule's radars include a synthetic aperture radar and a ground moving target indicator.

Engines

The UAV is powered by a single Arriel 1D1 turboshaft engine which can produce 559kW of electric power.

Performance

The AirMule can fly at a maximum speed of 185km/h. Its maximum altitude is 3,657m. Its maximum endurance is between two and four hours. The UAV weighs around 635kg and its maximum take-off weight is 1,088kg.

Ground control unit

The data retrieved and transferred by the AirMule will be stored at a ground control unit (GCU), which will be equipped with an air data computer for displaying its position. The GCU will monitor telemetry data supplied by the UAV using uplink and downlink communication devices.
