Book Description
This transcript from hearings before the Subcommittee on Science, Technology, and Space of the Committee on Commerce, Science and Transportation of the United States Senate includes a variety of witness statements and technical submissions including material from Goodyear Airships Programs, the U.S. Navy, NASA Lighter-than-Air Project Office, Piasecki Aircraft Corp., the U.S. Forest Service, Hov-Air-Ship Inc., and Senator Barry Goldwater. Primary uses discussed in detail are transportation and emplacement of very heavy assemblies and subassemblies encountered in the construction industry, and long-endurance surveillance of the coastal zone.

Book Description
The primary purpose of this AGARD report is to survey the results of studies, conducted over the last 15 years, to assess missions and vehicle concepts for modern propelled lighter-than-air vehicles. The report includes sections on utilization of these vehicles for patrol and surveillance, vertical heavy-lift, high altitude platforms and transportation missions. Keywords include: Airships, Design, Airborne operations, Surveillance, and Air transportation.

Book Description
This book is a compilation of ten technical archival publications describing the analysis of various icosahedrons, primarily of a nonlinear nature. Static and dynamic characteristics are considered, and other covered topics range from large displacements and rotations to the consideration of chaotic behaviour. There is a great deal of experimentation included in several papers, from a quasi-static point of view as well as that of dynamics.

Book Description
An aerial robot is a system capable of sustained flight with no direct human control and able to perform a specific task. A lighter than air robot is an aerial robot that relies on the static lift to balance its own weight. It can also be defined as a lighter than air unmanned aerial vehicle or an unmanned airship with sufficient autonomy. Lighter than air systems are particularly appealing since the energy to keep them airborne is small. They are increasingly considered for various tasks such as monitoring, surveillance, advertising, freight carrier, transportation. This book familiarizes readers with a hierarchical decoupled planning and control strategy that has been proven efficient through research. It is made up of a hierarchy of modules with well defined functions operating at a variety of rates, linked together from top to bottom. The outer loop, closed periodically, consists of a discrete search that produces a set of waypoints leading to the goal while avoiding obstacles and weighed regions. The second level smoothes this set so that the generated paths are feasible given the vehicle's velocity and accelerations limits. The third level generates flyable, timed trajectories and the last one is the tracking controller that attempts to minimize the error between the robot measured trajectory and the reference trajectory. This hierarchy is reflected in the structure and content of the book. Topics treated are: Modelling, Flight Planning, Trajectory Design and Control. Finally, some actual projects are described in the appendix. This volume will prove useful for researchers and practitioners working in Robotics and Automation, Aerospace Technology, Control and Artificial Intelligence.

Book Description
This is the fascinating story of the dream of a completely new aircraft, a hybrid of the airplane and rigid airship - huge, wingless, moving slowly through the lower sky. Its early and secrect experimenta; development took twelve years' time and one and a half million dollars. McPhee chronicles the perhaps unfathomable perseverance of the aircraft's successive progenitors and makes it seem as momentous as the first trip to the moon.
