Sci-Tech: UrbanAero’s fancraft AirMule making test flights

Urban Aeronautics in Israel has begun untethered unmanned flight tests of their vertical takeoff and landing (VTOL) prototype AirMule vehicle:

“AirMule Achieves Major Milestone on the Path to
Full Mission Demonstrations”

The AirMule, an unmanned VTOL (Vertical Takeoff and Landing) aircraft developed by Tactical Robotics Ltd., a subsidiary of Urban Aeronautics, Ltd., has successfully completed a major milestone in preparation for full mission demonstrations scheduled for next year. The aircraft has completed several fully automatic test flights in which it carried out take-offs, flights to and from a specified location and landing back at its point of origination.

The 1-ton vehicle is unique from all existing vertical take-off and landing aircraft in that it has no exposed rotors. This allows the aircraft to fly in air space that is off limits for any other aircraft.

During these tests height above ground is maintained by two laser altimeters (to be augmented soon by a radar altimeter for dusty conditions). Accurate position is maintained through data fusion of GPS signals, INS data and optical reference to markers on the ground.

Acoustic signature (Sound Pressure Level in dBA) has been recorded as a function of distance from the aircraft to a calibrated microphone and has been found to be significantly lower than an equivalent helicopter.

Additional flight testing is planned for next year with a second prototype, now in construction, planned to join the flight test program in the second half of 2014.

About Urban Aeronautics and Tactical Robotics

Urban Aeronautics Ltd, is the world leader in developing Fancraft technologies. These technologies are the foundation for a family of internal rotor (modified ducted-fan) aircraft with both manned and unmanned, civil and military applications. Due to their internal rotors, compact design and revolutionary ‘six-degrees-of-freedom’ mobility, these aircraft are uniquely suited to flight inside of cities and other obstructed environments where both fixed wing aircraft and traditional rotorcraft are unable to operate. Urban’s subsidiary, Tactical Robotics Ltd. develops these technologies for the military and unmanned market including the company’s flagship model, AirMule.
