Aerostat


An aerostat (from Ancient Greek ἀήρ (aḗr) 'air', and στατός (statós) 'standing', via French) is a lighter-than-air aircraft that gains its lift through the use of a buoyant gas. Aerostats include unpowered balloons and powered airships. A balloon may be free-flying or tethered.

A tethered aerostat filled with helium gas is in vertical and horizontal equilibrium at the end of a 4,000 ft long cable under tension, as shown in the figure below. The aerostat has a volume of 200,000 ft, and its maximum diameter is 38 ft. It has a drag coefficient of 1.2 based on the projected frontal area. The net weight of the aerostat is ...

An aerostat is an aircraft that generates lift by using a lifting gas to become lighter than air. Aerostats are named so because they utilize aerostatic lift, a buoyant force that does not require movement through surrounding air.Because of this, aerostats do not require a runway and are able to conduct a vertical take-off and landing (VTOL).

Tethered Aerostat Radar System in New Mexico. The first aerostats were assigned to the United States Air Force in December 1980 at Cudjoe Key, Florida. During the 1980s, the U.S. Customs Service operated a network of aerostats to help counter illegal drug trafficking. Their first site was built at High Rock, Grand Bahama in 1984.

Aerostat - The aerial platform, creating lift and carrying the aerial unit. Aerostat is the common name for anchored/tethered systems, in contrast to non-tethered airships. Aerial unit - The aerial unit includes the "operational payload" and any supporting systems for its operation (communication, power, computers, lights, etc.)

An aerostat provides persistence and never inconveniently passes over the horizon like a satellite does. Plus, its flight can be controlled more readily than that of an airship. Indeed, when measured on a cost-per-hour basis, there is no cheaper alternative for elevating payloads to improve their ranges. As an example, an aerostat at 500 feet ...

Aerostats are extremely useful in military operations, especially when equipped with radar and sensor systems. These systems enable the aerostats to detect and track threats such as aircraft ...

The unusual-looking ships—helium-filled aircraft called aerostats—rose to an altitude of 15,000 feet and floated quietly in the sky, each secured to a ground-based mooring system by long tethers. Insurgents on the ground were perplexed by what they saw. The airships didn't seem to move, nor did they fire missiles or release bombs.

aerostat system supports the automated interoperability between tactical/theater surveillance assets and the dissemination of threat data to operational forces to aid interdiction of hostile fires and unconventional threats. The 74K aerostat system leverages a wide-area, secure communications backbone for the integration of threat reporting from

The review has been presented to highlight the design process of the different aerostat envelope shapes that includes sizing ...

COMSovereign Holding Corp.'s Lighter Than Air Systems subsidiary, Drone Aviation, has been awarded a multi-unit, $8.4 million subcontract from a U.S. Government prime contractor for its Winch Aerostat Small Platform (WASP) and related support services to be used for national security and defense. The WASP is a highly tactical and mobile aerostat system which can be operated by a crew of two ...

Aerostat is an aerodynamically shaped non-rigid/flexible structure. The aerostats may be tethered or un-tethered. The lighter than air (LTA) helium gas is used to create the upward positive lift of the aerostat structures 1,2.The Archimedes' principle of buoyancy involved in creating the aerostat lift 3,4 is shown in the following Fig. 1.. They are actually employed at greater heights to ...

The Class IV Aerostat for the U.S. Air Force. ILC Dover supports design of the initial Class IV aerostat for the United States Air Force. We manufacture all operational Class IV aerostats, which have r volumes of 275,000 to 420,000 cubic feet. The Class IV aerostat can withstand hurricane-force winds in excess of 90 MPH and is able to operate ...

The aerostat will be ADS-B Out equipped, aiding its visibility to appropriately equipped aircraft. Hubbard also described the vehicle's "flight termination system," which includes a valve that would be opened to slowly release helium from the aerostat that could be activated in an emergency, such as detachment from its tether. ...

The approval of the potential aerostat deals is the latest in a string of Polish deals the State Department has OKed over the last year, from an estimated $4 billion in integrated air defense ...

"Aerostat, I think, is synonymous with the old fight, counterinsurgency," Lareina Adams, a project manager for terrestrial sensors, told C4ISRNET during an interview at the Association of the U.S. Army convention in Washington. "But what we're trying to see is if we can expand the applicability of the aerostat to other missions that ...

Tethered Aerostats. Tethered aerostats (TA) are the most cost-effective platforms for aerial surveillance or communication. The TA can serve as high raise towers with various types of equipment installed on the top. Being up to 5 000 m tall, these "towers" significantly expand the range of the said equipment. Unlike any other manned or ...
