Book Synopsis The Problem: Instantaneously Effecting Controlled Balloon-system Descent from High Altitude by : James F. Dwyer
Download or read book The Problem: Instantaneously Effecting Controlled Balloon-system Descent from High Altitude written by James F. Dwyer and published by . This book was released on 1980 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for a technique of instantaneously effect controlled balloon-system descent from high altitude prompted the development efforts reported herein. The background, the approach, test flight data, and the technical problems that frustrated the successful development of the desired technique are included. A simplified model of the shape of a partially full balloon is presented (a model that should also approximate the dimensions of subpressure shapes). Some heretofore unpublished information on apex valve characteristics and subpressure effects are included together with recommendations for any future work of this problem. Significant supplementary findings and historical perspectives are noted. (Author).

Download or read book Factors Affecting the Vertical Motion of a Zero-pressure, Polyethylene, Free Balloon written by James F. Dwyer and published by . This book was released on 1985 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper critiques existing aerodynamic-thermodynamic models for predicting the vertical motion of free balloon systems. It demonstrates that: a) the aerodynamic drag coefficient model should be based on Froude number and fractional volume as well as Reynolds number; b) there has been a widespread error in definition of the instantaneous mass of the balloon film involved in the heat transfer process; c) the gas bubble cannot be modelled as a sphere; d) the gas bubble is asymmetrical except when near or at its natural ceiling altitude; and e) the actual gas bubble shape, and most probably the added mass, is directly related to the type of gore pattern. Finally, a procedure is proposed for the analysis of actual flight data to enable the development of a practical, but also theoretically sound, model of the aerodynamic drag coefficient of a zero-pressure, free balloon- and subsequent refinement of the heat transfer models for direct and reflected solar energy.

Book excerpt: This document serves as the third revision of the USAF Parachute Handbook which was first published in 1951. The data and information represent the current state of the art relative to recovery system design and development. The initial chapters describe representative recovery applications, components, subsystems, material, manufacture and testing. The final chapters provide empirical data and analytical methods useful for predicting performance and presenting a definitive design of selected components into a reliable recovery system.

Download or read book An International Legal Framework for Geoengineering written by Haomiao Du and published by Routledge. This book was released on 2017-10-18 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geoengineering provides new possibilities for humans to deal with dangerous climate change and its effects but at the same time creates new risks to the planet. This book responds to the challenges geoengineering poses to International Law by identifying and developing the rules and principles that are aimed at controlling the risks to the environment and human health arising from geoengineering activities, without neglecting the contribution that geoengineering could make in preventing dangerous climate change and its impacts. It argues first that the employment of geoengineering should not cause significant environmental harm to the areas beyond the jurisdiction of the state of origin or the global commons, and the risk of causing such harm should be minimized or controlled. Second, the potential of geoengineering in contributing to preventing dangerous climate change should not be downplayed.
