Tethered Airship System

Due to earthquakes, floods ,military conflict and other disasters, ground communications networks were interrupted and blind spots were extisted; due to large gatherings, communication expansion and safety monitoring are necessary .

The emergency communication vehicle cannot get close to disaster area, the high-altitude base station can be used in connection with ground station or satellite communication ways to ensure the emergency communication and monitoring requirements in the area.

The high-altitude base station program mainly uses flying airship to carry 4G equipment, optical-electric pods, radar and other loads to achieve long-distance coverage, to avoid terrain undulations, using VOLTE to solve emergency voice communications and image monitoring.

Airship:

Airship is made by multiple fabric with high frequency hot pressing . The lift of the tethered blimp is derived from the difference in density between the helium and the surrounding air. Additional lift is generated by wind speed through the hull and tail section.

The system is widely used because of its simple structure, flexible lifting, good safety, low price, reusable and strong maintainability. Our tethered blimp is mainly used to communicate with the earth, to observe and carrying experiments. Our design idea is that the project is safe and reliable, multi-purpose, parts and materials are as localized as possible, and it has good operability and practicability.

Airship including:

Environmental pressure control system:
Emergency system
