Lighter-Than-Air (LTA) Systems is an very unique course in Aeronautical Engineering which is designed to introduce to the technology of buoyant systems which were on the technological forefront in early 1990's. In the recent years the interest in the LTA Systems have been restored due to the benefits that they provide with long endurance and low fuel consumption.
This course is offered as an Open Elective II for the students with different disciples of study such as Civil Engineering, Computer Science Engineering, Electrical Engineering, Food Technology, and Mechanical Engineering.

Intended Course Outcomes:
Upon successful completion of this course, the students will be able to
Apply the principles of aerostatics and buoyancy to analyze the static lift characteristics of different LTA configurations.
Calculate static lift, pressure height, and other key performance parameters for given LTA system designs.
Analyze the influence of environmental factors (temperature, pressure, humidity) on LTA system performance.
Evaluate the selection and application of appropriate envelope materials and ground handling techniques for different LTA systems
Apply design methodologies for the development of aerostats and airships, considering factors like shape, size, and internal structure.
Analyze the design considerations and challenges associated with high-altitude airships and hybrid LTA systems.
