Urban's AirMule set to start untethered hover trials

摘要

Urban Aeronautics is planning untethered hover flights in March for its vertical take-off and landing AirMule unmanned air vehicle, having achieved more than 30 tethered tests of lmin duration.rnDesigned for cargo delivery and medical evacuation missions, and formerly called the Mule, the UAV completed tethered tests in wind speeds of up to 50kt (92.5km/h). It was hovered autonomously at an altitude of 2ft (60cm) using its fly-by-wire control system, which employs inertial measurements augmented by GPS navigation.
