Product overview
United Aircraft presents the TD550 as a powered coaxial unmanned helicopter for heavy-load work and high-altitude takeoff and landing. Its architecture combines an aviation turbocharged piston engine with dual-redundant HeliAP flight control. The manufacturer describes a simple structure that supports convenient disassembly, assembly and installation, with compact installed dimensions for transport. However, no numerical dimensions, empty weight or assembly procedure.
The integration options cover electro-optical observation, cargo attachment, communications relay, SAR radar, high-definition mapping and airborne weapons. These are potential payload categories, rather than an itemized supplied configuration. Manual, programmed and one-command autonomous flight are described, alongside autonomous takeoff and landing, position holding, obstacle avoidance, emergency return and precise delivery. Procurement should therefore establish the selected mission equipment and its integration requirements.
The published operating figures depend on loading and altitude: endurance is 6.5 hours with 100 kg at sea level, two hours with 260 kg at sea level, and two hours with 120 kg at 5000 m. Maximum takeoff weight is also qualified at sea level. Separate wind figures apply during takeoff and landing and while airborne. Environmental claims include moderate rain, light snow and damp-heat resistance.
