Hitec North American Sales & Support San Diego, CA www.HitecCS.com autopilot to begin the automated launch sequence, allowing the UAV’s powertrain to start and FLARES’s docking clamps to be released. In turn, FLARES keeps track of key timing and altitude stepping points through its internal clock and altimeter respectively, which trigger it to transition from ascent to dash. Despite its metallic appearance, the FLARES airframe is mostly built from carbon fibre and it features four rotor arms. In FLARES 2, each one is designed with a ‘leg’ or strut for landing, while in FLARES 3, two of the legs are designed as fin-like components for greater stability during the dash phase of launch. Each arm on FLARES 2 integrates two electric motors and propellers in a coaxial configuration. In FLARES 3, this is doubled, meaning two motors per prop and 16 motors in total, for extremely high redundancy in launch and recovery, and thus minimising the chance of ScanEagle or Integrator suffering damage due to a motor failure. The four arms run into the central hub, where FLARES’s Lithiumion batteries, ESCs (with Currawong’s Velocity ESCs among those used), autopilot and flight sensor package sit. A few components outside of the multirotor include the capture rope for recovery, an automated winch that installs at the ground to lower the captured UAV downwards for safe and steady recovery, and a mast-like, proprietary, mechanical anchoring point to fix the rope to the ground, referred to by Insitu as MARS (mast-augmented recovery system). “That differs from SkyHook in the sense that it folds very neatly into an 80 in storage container, hence that mast structure can be transported around in a much more mobile way, and secured into most terrains to ensure a fixed position for the bottom end of the rope during recovery,” Pearce says. In addition to the redundancy espoused as a vital target over iterations of FLARES, power efficiency is critical, with Hood Tech Mechanical’s credo of ‘hover at half power’ indicating that it designed the multirotor to be capable of achieving hover with half of its maximum thrust capacity while still carrying a ScanEagle or Integrator underneath. Hartley says FLARES can do a better job of gust rejection and operations in high sea environments than most integrated, VTOL-transitioning UAVs. It can maintain stability against winds of up to 30 knots and gusts up to 10 knots by virtue of its greater size, power and authority in pitch and roll than one would find on an aircraftinstalled VTOL system. Insitu’s engines While both UAVs operate on the basis of two-bladed, carbon-fibre pusher propeller drives, their powertrains start to differ greatly from each other as one moves forwards into their engines. ~
