TF500H

Greater Payload & Enhanced Safety: Powered by Heavy Fuel

The "TF 500H" Heavy-Duty Unmanned Helicopter leverages a heavy fuel engine to deliver superior payload capacity and enhanced safety margins compared to gasoline-powered alternatives. This maritime-capable platform is equipped with a dual-redundancy flight control system, enabling fully autonomous takeoff and landing, precision hovering, pinpoint cargo delivery, and emergency return-to-home capabilities. Boasting exceptional environmental and site adaptability, it excels in specialized low-altitude logistics missions, including: transportation of engineering equipment and spare parts, urban and wildland firefighting, resupply operations, medical evacuation (MEDEVAC), emergency rescue, and communications relay. Its versatility further extends to innovative applications such as weather modification and scientific research payload integration.

Technological Advancement

High-Reliability & High Environmental Adaptability Platform Technology — Fully Independently Developed System & Environmentally Adaptive Design

01

Tandem Helicopter Overall Technology

Adopting a tandem dual-rotor layout design, the front and rear rotors are arranged longitudinally to maintain fuselage stability, simplify structure, and reduce weight. The dual-rotor layout provides stronger aerodynamic stability; the increased rotor area enhances lift, and its wind resistance performance is superior to that of conventional single-rotor helicopters.
02

Flexible Rotor Hub Technology

Integrated with elastic bearings, it realizes flexible flapping and lead-lag movements of the rotor blades, significantly reducing the number of mechanical components. The flexible rotor hub design lowers structural complexity; elastic materials can absorb high-frequency vibrations during rotor movement to achieve vibration suppression. Its rigid connection feature enables more direct transmission of blade pitch commands, reducing control delay and improving maneuverability.
03

High-Efficiency Rotor Technology

The rotor system adopts lightweight design technology, integrating the advantages of no tail transmission, no need for tail reducer and tail rotor. It avoids the risk of tail rotor failure, improves maneuverability, increases hover efficiency by 10%~15%, and features a compact structure and small overall size, adapting to shipboard environments with limited space.
04

Long-Distance High-Power Transmission Technology

It adopts high-torque brushless motors combined with high-power ESCs to achieve linear control of power output; the dual-motor redundant architecture can still maintain stable power output in case of failure; the lightweight transmission structure reduces aircraft weight and enhances transmission strength.
05

Airframe Lightweight Technology

Composite materials are used as the main load-bearing structure, reducing weight while improving strength; the modular design facilitates rapid replacement of mission modules and reduces the weight of redundant structures.
06

Power Adaptability Modification Technology

Equipped with dual-rotor power redundancy configuration, it can automatically redistribute power when a single motor fails, maintaining more than 80% of the load capacity, which is suitable for high-reliability scenarios such as material transportation.

High-Safety Intelligent Flight Control Technology

Fully Independently Developed System & Military-Grade Redundancy

The dual-redundancy flight control system has a hot-switching time of <100ms between the main and backup flight control computers, and can still maintain more than 80% of the control capability when a single system fails; power system fault tolerance: the tandem dual-rotor design allows automatic adjustment of power distribution when a single rotor fails to maintain hover stability. It supports autonomous mission execution, integrates core flight control technology, and enables fully autonomous takeoff and landing, precise fixed-point delivery, and emergency return.
