"Tethered" Aerostat

Details

For several decades now Aero Drum Ltd is a supplier of tethered Aerostats to various clients and partners worldwide. We are specialized in design and production of carrier only - Aerostat, stabilization sail, main line (with or without internal power cable), Aluminum base for ... your remote sensing equipment in the stable point between the Aerostat and main line, and rest related to the Aerostat system itself. Our Aerostat Surveillance Systems are used for: - Intelligence Gathering – Reconnaissance – Research - Force Protection - Border Port Security - Beyond Line of Sight (BLOS) Communication Relays - Situational Awareness - Rapid Acquisition - Disaster Response - Incident Awareness & Assessment - Monitoring Air Quality & Atmospheric Conditions - Critical Infrastructure Security - Various Atmospheric measurements - Wild life count - Wild life monitoring and filming, and many more applications Structural integrity and genuine design solutions - The envelope of our Aerostats is made out of High-quality Polyurethane (TPU) film imported for UK or USA. Three thicknesses are mainly used 100, 125 and 150 microns. Double or even triple welding technology process is guarantying that the helium permeability is 0.5 maximum daily regardless to the volume. We care about your helium or hydrogen expenses.Aerostats are a type of lighter-than-air (LTA) aircraft that remain aloft primarily through the use of buoyancy provided by a gas-filled envelope. They are commonly referred to as "tethered" or "unmanned" balloons. Aerostats have been used for various purposes, including military surveillance, telecommunications, and scientific research. A typical aerostat consists of a large envelope filled with a lighter-than-air gas, such as helium or hydrogen, which provides the buoyancy necessary to lift the aerostat off the ground. The envelope is usually made of strong, lightweight materials such as nylon or polyester. The aerostat is usually attached to the ground by a tether or mooring cable, which also serves to provide stability and control. Aerostats are often used for surveillance purposes, particularly in military applications. They can be equipped with various sensors, cameras, and communication equipment to monitor and collect information from the surrounding area. Since aerostats can remain airborne for long periods, they offer a cost-effective and persistent surveillance solution, especially in areas where infrastructure is limited or challenging. One of the advantages of aerostats is their ability to operate at high altitudes, providing an elevated vantage point for surveillance or communication purposes. They can stay aloft for days or even weeks at a time, depending on the design and operational requirements. However, they are subject to weather conditions, and strong winds can affect their stability and performance. Aerostats are also used in the field of telecommunications, particularly for providing wireless connectivity in remote areas or disaster-stricken regions where traditional infrastructure may be damaged or absent. By carrying communication equipment, such as cellular base stations or Wi-Fi transmitters, aerostats can establish temporary networks and enable connectivity over a wide area. In summary, aerostats are gas-filled, lighter-than-air aircraft that are tethered to the ground. They find applications in military surveillance, telecommunications, and scientific research, offering persistent aerial platforms with the ability to operate at high altitudes for extended periods.

RC safety valve (several sizes depending on Aerostat volume) that is set in every envelope is a security that will keep your expensive equipment. Our safety valves can be RC operated or integrated in your own onboard systems.

Main line is polyester Dyneema starting at 4 mm up to 10 mm depending on the Aerostat volume. We have also the main line with power wires integrated in the core of the line. This is important feature for prolonged autonomy (days). The main line is Polyester (waterproof) Dyneema or Dacron quality depending on Aerostat volume. The T aluminum shape is a base for your remote sensing equipment. It is situated between the main line and Aerostat harness system. This is a stable point and vibration free position in the complete system.

Automatic Leveling System – Originally developed during years of field work to allow to the aerostat to respond to wind changes and level itself regardless to operators. This way it is always turned into wind resulting in lowest aerodynamic resistance possible what directly affects good stability.
