| Summary |
This book presents select peer reviewed proceedings of the International Conference on Design and Engineering of Lighter-Than-Air Systems (DELTAs 2022) which was held at the Department of Aerospace Engineering, Indian Institute of Technology (IIT) Bombay. It highlights current research trends and advancements in the field of lighter-than-air (LTA) systems. The topics covered include design (conventional and unconventional), aerodynamics (CFD), structures, loads and materials, stability and control, operations and ground handling, multidisciplinary design optimization, and novel applications of LTA systems. The book will be a valuable reference for researchers and professionals interested in lighter-than-air systems and allied fields |
