Cobra Worldwide‘s partnership with Thai unmanned aerial car (UAV) producer HG Robotics culminated with the event of a completely new manufacturing idea for the carbon fibre composite flying wing of the “VETAL” vertical take-off and touchdown (VTOL) drone.VETAL is a twin-rotor, tail sitting drone that HG Robotics has not too long ago launched for large-scale agricultural surveys, in addition to normal surveillance monitoring.
Constructing upon earlier expertise as a element producer for HG Robotics, COBRA has strengthened the partnership with the brand new VETAL drone, supporting HG with the event of a completely new manufacturing idea for the carbon fiber composite flying wing. Having developed the preliminary flying form of the VETAL platform, HG Robotics had produced the primary flying prototypes utilizing a extra conventional UAV building strategy of skinny composite skins, with ribs and frames supporting the hole construction.
Drawing from its a long time of expertise with shut tolerance moulding of EPS foam cored sandwich elements for the watersports market, COBRA proposed a hybrid resolution, combining each hole and cored sections, for the flying wing. The principle physique of the plane includes a PVC foam sandwich shell with a low-density EPS foam rib which, mixed with a totally foam-cored tail construction, delivered a whole airframe fractionally lighter than the shopper’s difficult goal.
Moreover, to scale back weight, a mixture of carbon fibre stitched biaxial materials and UD reinforcements are used wherever doable, with further glass fibre strengthened sections of the laminate being employed the place radio transparency or insulation from metallic components is required.
