Description
A fiber-optic tethered quadrotor system with jam-resistant fiber data link and continuous 5 kW ground power for unlimited hover time. 900 mm wheelbase airframe flies at 33 m/s up to 5,000 m in IP56 protection. Backpack-portable tethered box deploys in 5 minutes by a single operator.
The optical fiber 4-axis tethered drone system combines a compact quadrotor with a fiber-optic tethered power and communication ground terminal. The airframe has a 900 mm symmetrical motor wheelbase and 1,200 × 1,200 × 500 mm unfolded dimensions (550 × 550 × 500 mm folded), built from carbon fiber and aluminum alloy for light weight, high strength and corrosion resistance. Flight performance includes 10 m/s ascent and descent, 33 m/s flight speed, Level 6 wind resistance, ≥5,000 m flight altitude, and ≥50 minutes no-load endurance at sea level with 24-minute charging. Maximum load is 5 kg (optional 10–15 kg), full load 10 kg. Hovering accuracy is vertical ±0.5 m and horizontal ±1.5 m with GNSS; protection is IP56, allowing flight in moderate rain. Flight modes include manual, automatic, fixed altitude, fixed point, sport and attitude. The tethered box accepts 110–240 VAC input and outputs adjustable 500–750 VDC (default 750 VDC) at 5,000 W rated / 6,000 W peak, with comprehensive protection, touch-screen status display, automatic cable tension following takeoff and landing, and optional dual-fiber data communication (FC interface). Cable is 100 m standard (200 m optional), φ3.5 mm, 21 g/m, breaking force ≥200 kg, ≥3,000 retraction cycles. The box measures 470 × 210 × 470 mm and weighs 16.5 kg including cable. The onboard power unit converts 400–750 VDC input to 50 VDC output at ≥3,000 W rated (dimensions 180 × 160 × 68 mm, weight about 2 kg — source lists 1,990 g).
