Lighter-Than-Air Systems
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.
