MYUAV Tethering Power System for Drones

Product Specification

MYUAV What is tethering power system for UAVs

The Tethering Power System combines unmanned aircrafts with tether system and base power station. The system provides continuous power to the unmanned aircraft via a tether cable. It enables unmanned aircrafts to stay in the air for an elongated time, and makes them independent of on-board batteries.

The tether power system provides 33m-360m of tether cable which is suitable for small drones like DJI Mavic 3 and the big drones with MTOW 55kgs. The system can be customized according to specific requirements. The tether power system displays key information to make it convenient for the operator to monitor status constantly.

FAQ

1. **Q: What is MYUAV's tethered power station? **.
**A:** MYUAV's tethered power station is an innovative high-altitude power generation solution that uses tethered drone technology to connect a large drone to a ground power source. The drone carries a small wind turbine or solar panel to fly high into the sky, using high-altitude wind or sunlight resources to generate electricity, and then sends the power back to the ground via tethered cables.

2. **Q: How does MYUAV tethered power station work? **.
**A:** The working principle is mainly to use the drone as a platform to lift it to the height that the traditional wind turbine cannot reach, where the wind speed is more stable and strong, thereby improving the power generation efficiency. The UAV receives a constant supply of electricity through high-strength cables attached to the ground to maintain the flight of the UAV and the operation of the power generation equipment.

3. **Q: How efficient is the MYUAV tethered power station? **.
**A:** Because the actual data depends on the specific UAV model and the configuration of the power generation equipment, MYUAV may have increased the power generation per unit area through the efficient use of wind or solar resources. Compared to traditional ground-based power plants, high-altitude wind or solar power has a higher power generation potential per unit area, but the exact efficiency figures need to refer to the product performance indicators provided by MYUAV company.

4. **Q: In what environment can MYUAV tethered power stations operate? **.
**A:** MYUAV's tethered power stations should be able to operate within a safe range of meteorological conditions, such as avoiding extreme weather conditions, while ensuring the safety and stability of tethered cables. The specific operating environment conditions should be consulted with MYUAV for detailed standards prior to purchase.

5. **Q: How to recover and maintain tethered UAVs? **.
**A:** MYUAV may be equipped with an automated or semi-automated recovery system to safely land and recover the teemed UAV if necessary, while performing regular maintenance checks on the power generation equipment on the UAV. The maintenance process may include integrity inspection and repair of the drone body, power system, power generation equipment and tethered cables.
