Book excerpt: There has always been a sense of romanticism attached to balloons, as they glide effortlessly and soundlessly in a world of their own. However, the history of balloon flight is often underestimated, as are the fascinating scientific breakthroughs that can be attributed to it.

Download or read book Zeppelin written by Ernst August Lehmann and published by . This book was released on 1937 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a thorough first person account of zeppelins, their history and flights. This book was being translated by Leonhard Adelt, who was on board with Lehmann as a guest during the Hindenburg's last flight. The book had recently been published in German when the Hindenburg was destroyed. The English translation, completed by Jay Dratler, was published in 1937 with a preface and closing chapter by American airship captain Charles E. Rosendahl, who had interviewed Lehman on his deathbed. https://en.wikipedia.org/wiki/Ernst_A._Lehmann

Download or read book Lighter than Air Robots written by Yasmina Bestaoui Sebbane and published by Springer Science & Business Media. This book was released on 2011-11-15 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Principles of Aerostatics written by John A. Taylor and published by Createspace Independent Publishing Platform. This book was released on 2014-07-15 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Principles of Aerostatics presents the complete theory of static lift for airships, aerostats and balloons. Concepts are laid out, and building on the derivation of temperature, pressure, density and humidity in the atmosphere and the gas laws, formulas for static lift are derived. The variation of lift with atmospheric and airship parameters, climb and descent, and flight above pressure height are then explored. Both SI and United States Customary Units are employed throughout, and worked examples and calculator programs are provided. The mathematical processes can followed by a reader with an understanding of high school algebra. "This is an excellent and unique work bringing the strands of basic theory together and rendering them into a workable series of mathematical expressions which can be used by any individual with a hand held scientific calculator. It is a most significant contribution to the LTA industry." - Dick Chadburn - Former Chairman, The Airship Association
