Alpha Unmanned Systems and UAV Navigation

Alpha Unmanned Systems and UAV Navigation jointly announced today the introduction of a fully automatic autorotation feature on the Alpha 800 platform that sets it apart from its competitors.

Autorotation, a critical capability for helicopters in case of engine or tail rotor failure, is described as ‘gliding the craft,’ something all manned helicopter pilots are trained to do. It is notoriously difficult to achieve and therefore takes extended practice.  In the case of a UAV helicopter, no automatic autorotation has been possible… until now.

First of its kind

The new capability represents an important step forward in that it enables a UAV in distress to be safely landed. Minimizing risk to people and property on the ground, it also greatly increases the likelihood that the payload and other expensive components on the platform will be recovered.

Alpha Unmanned Systems and UAV Navigation have been collaborating on this technology for several years, the robust Alpha 800 fitted with sensors and hardware to feed the necessary information to UAV Navigation’s VECTOR autopilot.  The Alpha 800 platform has proven to be very effective for developing software as well as for extensive simulation with an advanced Hardware In the Loop simulator. Actual flight-testing confirmed the results with repeated successful landings following autorotations from a variety of altitudes, wind directions and headings. In all cases, no engine power whatsoever was supplied to the rotors.

Autorotation is just one of the safety features provided by the VECTOR autopilot to the ALPA 800 UAV. The system is also capable of flying in GPS-denied environments and in situations where the onboard Magnetometer is unavailable.

We will be happy to hear your thoughts
