Special Session V: Lighter-Than-Air Systems.

Every country around the globe needs an enduring and reliable silent eye in the air for defense purposes and a green-aviation technology for civil applications. One of the potential solutions to meet both requirements is Lighter-Than-Air (LTA) Systems. The two main types of LTA systems are Aerostats (consisting of an aerodynamically shaped un-powered balloon tethered to a ground station) and Airships (free flying balloons that have a powerplant and a three-axis control system).

Despite their initial popularity in the early 20th century, the use of Aerostats for aerial surveillance, and Airships for transportation and other purposes declined in the following decades due to safety concerns, cost, and the development of more efficient aircraft. With advancements in technology and the need for sustainable aerial platform and green transportation systems, Aerostats and Airships have once again gained attention as a potential solution.

In recent years, there has been a renewed interest in LTA Systems, particularly for their potential as a greener alternative to conventional modes of aerial platforms and air transportation. Aerostats are much more cost effective and easily re-locatable and re-furbishable as compared to satellites, and they have much large endurance compared to UAVs. Airships are being considered as an alternative to traditional shipping methods, as they can carry large payloads over long distances while using significantly less fuel than airplanes or ships. Airships have a unique set of advantages compared to other forms of aircraft, including their ability to stay aloft for long periods of time and their ability to carry heavy loads over long distances. They also have a unique aesthetic appeal and can be used in a variety of creative ways. As the demand for sustainable and low-emission transportation solutions continues to grow, airships are poised to play an increasingly important role.

The design and development of Aerostats and Airships involve multiple disciplines that are associated with each other. There are many technical challenges related to the design, engineering, operations, performance, economics, business models, and regulations & policy that need to be addressed to achieve the most reliable LTA systems.

This session on LTA Systems aims to foster discussion and exchange of ideas among researchers and practitioners in the field and to contribute to the development of this technology and its applications.
