Beneath the starfish in the top enclosure are most of the electric and avionics systems. These include the batteries, which serve as balancers for electrical loads and for the CoG (and it also provides back-up energy in the event of an engine malfunction), the autopilot, navigation systems, power management unit (PMU), and an engine management board developed in-house to handle the running and cooling of the engine. Below these is the engine compartment, which is completely isolated from the avionics chamber. Inside it is the engine, an alternator, a fuel pump, an EFI system and the cooling system. “It’s important to note that we’ve developed two cooling systems: an air-cooling system that’s the base configuration, and a water-cooling system for end-users who maybe expect to be flying in temperatures of upwards of 40-50 C. Both configurations have been successfully tested,” Skantze adds. Forward of the engine compartment are the payload gimbals and other mission installations, and beneath are the X12’s legs. Fuel hoses run inside the legs, with the ‘feet’ or pontoons containing the fuel tanks (also helping to keep the CoG low) as well as comms antennas, while the GNSS antennas sit atop the hub. “One thing we’ve tried to optimise is the useability of our UAVs,” Skantze says. “That’s why for instance we’ve gone from rotor arms that had to be screwed in to ones that snap into place in seconds simply by folding outward, and clicking into the lock position at the correct angle, all without the need for tools. Then a manual unlocking of the arms is quickly performed after the UAV is recovered.” While the 25 kg X8 is portable by a single person, Xer recommends two personnel carrying it and the X12 from a road vehicle – especially the X12, given that it weighs more than 60 kg when fully loaded and fuelled. With two trained personnel, either UAV can be set up in 30 seconds, with a short period after for electronic start-up and engine warm- up before take-off (notwithstanding any waypoint programming, geo-fencing or other mission planning details not addressed beforehand). “The more you need tools, or to handle cables or screws or the like, the more things can get damaged, lost or otherwise go wrong in the field,” Skantze comments. “All the parts of the starfish – the hull, arms and folding and locking brackets for the arms, as well as all the structural fittings and mounts – have been developed in-house.
