As demand grows for reliable aerial platforms capable of remaining airborne for extended periods, Nanjing Flying is strengthening its tethered Drone solutions with a focus on stable flight, continuous power delivery and flexible mission support. Its FlyCart30 Tethered Drone system combines an aerial power module, ground tethered box and intelligent cable management technology to provide a practical solution for long-duration aerial operations. The system is designed around the keyword stable flight tethered Drone, emphasizing dependable power transmission and controlled operation rather than short-duration battery flight.

Continuous Power for Extended Flight

One of the most important limitations of conventional battery-powered UAVs is flight duration. Nanjing Flying addresses this challenge by connecting the FlyCart30 to a ground-based power system through a dedicated tether. The product supports continuous power supply from a generator and is designed for flight durations of more than 24 hours. Depending on the required operating height, users can select 110m, 220m or 330m cable configurations, corresponding to supported flight altitudes of 100m, 200m or 300m.

This architecture changes the way long-duration aerial tasks can be organized. Instead of repeatedly landing the Drone to replace batteries, the tethered system provides a continuous electrical connection between the ground module and the Drone-mounted power unit. For applications requiring persistent aerial presence, this approach can significantly reduce interruptions and make deployment more efficient.

Intelligent Cable Management Supports Stable Flight

Stable flight depends on more than the Drone itself. The relationship between the Drone and its tether is also critical, especially when the Drone changes altitude. The FlyCart30 Tethered Drone uses an intelligent cable reel with a variable-speed adjustment range of . The cable follows the Drone's upward and downward movement, synchronizing its deployment and automatic retraction. The system also provides continuous adjustment of cable pulling force from , helping manage the tether during flight.

This combination of dynamic cable control and controlled pulling force gives the system a more coordinated operating structure. Rather than treating the tether as a passive connection, Nanjing Flying incorporates cable management into the overall flight support system. This is an important design consideration for users looking for a stable flight tethered Drone that can maintain a controlled connection with its ground power source.

High-Power Tethered Architecture

The ground module is designed for high-power continuous operation. It accepts 380±10%VAC three-phase five-wire input and provides 800–1000VDC output, with a factory default of 1000VDC. On the Drone side, the air module accepts 800–1000VDC and provides a stable 58.5VDC output, with 20kW rated long-time output

The high-voltage, low-current transmission architecture is designed to support efficient power delivery through the tether. The Drone-mounted module replaces the compatible Drone battery and can be directly plugged in and locked into position. the air module is designed as a dedicated power interface for the tethered configuration rather than requiring repeated manual battery replacement during extended operation.

Safety Designed Into the Power System

Long-duration aerial equipment requires reliable protection at both the electrical and mechanical levels. Nanjing Flying's FlyCart30 Tethered Drone includes multiple protective functions covering overvoltage, overcurrent, overtemperature and short circuit conditions. The system can also respond to cable breakage, short circuit and detachment by automatically shutting down high voltage. If the generator stalls, the cable maintains its automatic recycling function.

The tether itself uses a multi-layer construction incorporating silver-plated copper, Teflon insulation, single-mode fiber, sheath film and Kevlar weaving. This structure combines power transmission, communication capability and mechanical reinforcement within the cable assembly. The system also supports fault display and acoustic-optic alarms, allowing operators to receive clear information when abnormal conditions occur.

Flexible Control and Real-Time Information

Another advantage of the system is its range of control options. The tethered box supports buttons, an app, HMI and the Drone controller, while the communication system can support multi-terminal interconnection and optional fiber communication. Operators can view information such as voltage, current, temperature, power consumption, cable outlet length and operating time.

This makes the system easier to integrate into different operating environments. Instead of relying on a single control method, Nanjing Flying provides several interfaces that can be selected according to operational requirements. The combination of real-time data and multiple control modes also helps users understand the working status of the tethered power system during extended aerial operation.

Designed for Powerful Aerial Lighting

The FlyCart30 Tethered Drone is also compatible with high-power lighting solutions, making the platform particularly suitable for situations where aerial illumination is required for large outdoor areas. The L24 floodlight provides 2400W lighting power and can reach 3600W in super-bright mode,  Its lighting area can reach approximately 3,000 square meters at 50m and 10,000 square meters at 100m.

For applications requiring even greater lighting output, the L48 floodlight offers 4800W power and up to 10,000W in super-bright mode, lumens. Both solutions can automatically turn on or off according to the Drone's movement and support control through the button, app, HMI or Drone controller.

This combination gives Nanjing Flying's tethered Drone platform a practical role in nighttime operations, temporary area lighting and other scenarios where elevated, high-output illumination is required.

A Platform for Multiple Mission Payloads

Beyond lighting, the FlyCart30 Tethered Drone can accommodate several specialized payload systems. The product page lists cleaning spray equipment, fire extinguishing systems, a speaker and spotlight system, as well as other mission-oriented accessories. The fire extinguishing systems support fire foam or water-based agents,

Nanjing Flying Focuses on Practical UAV Engineering

For Nanjing Flying, the development of a stable flight tethered Drone is not simply about extending flight time. It is about building a coordinated system in which power transmission, cable movement, Drone operation, safety protection and payload integration work together.

The FlyCart30 Tethered Drone demonstrates this approach through its continuous generator-powered operation, intelligent cable management, high-power electrical architecture and broad payload compatibility. With configurable tether lengths, multiple control methods and specialized aerial lighting options, the platform provides a flexible foundation for users who need sustained aerial capability without relying solely on conventional battery endurance.

As tethered Drone technology continues to develop, Nanjing Flying is positioning stable power delivery and controlled aerial operation as key elements of its product strategy. By combining long-duration flight capability with practical payload options, the company is creating tethered Drone solutions designed for demanding aerial environments where reliability, endurance and operational flexibility matter most.
