Book Description
A preliminary investigation of the aerodynamic and control characteristics of a flexible glider similar to a parachute in construction has been made at the Langley Research Center to evaluate its capabilities as a reentry glider. Preliminary weight estimates of the proposed vehicle indicate that such a structure can be made with extreamly low wing loading. Maximum temperatures during the reentry maneuver might be held as low as about 1,500 degrees F.

Book Description
An investigation was made in the Langley Unitary Plan wind tunnel to determine the behavior of paraglider models at moderate to high supersonic speeds. The models were deployed from a sting in the supersonic stream and steady-state aerodynamics performance data were obtained. Maximum values of the lift-drag ratio were about 1.4 at a Mach number of 2.65 and about 1.2 at a Mach number of 4.65. The angles of attack over which the models could be flown were limited by unsteady behavior of the canopy.

Book Description
If you’re interested in paragliding or have already started training, this book is what you need. It includes: Learn the essentials of keeping safe – like how turbulence forms behind hills and terrain – through to the intricacies of thermalling with birds of prey, thousands of feet high. All the know-how to help guide you from your first thrilling, ground-skimming flights to aerobatic manoeuvres and beyond. Follows the teaching syllabuses of the BHPA (UK), USHPA (USA) and other national paragliding bodies, including Canada, South Africa, Australia and New Zealand. What the experts say: “Absolutely bang up to date. Its high standard of writing conveys intricate concepts in an easy-to-understand way. The layout, technical illustrations and time-lapse photography combine to produce a very aesthetically pleasing result” – Steve Uzochukwu, Skywings Magazine, BHPA “As a new pilot entering this beautiful 3D game, it’d take years of research and conversations with experts to glean all the information this book provides in its 300+ pages. Coupled with an easy reading style, this book is an absolute must” – Wally Arcidiacono, Bright Flight Paragliding, Australia “Paragliding: The Beginner’s Guide is essential reading for all our students” – Jess Cox, Chief Flying Instructor, Fly Sussex, UK “This book is now standard issue to all of our beginning flight students” – Brad Hill, Discover Paragliding, USA 340 pages of comprehensive instruction and information including: Understanding the air Learn how the air moves and what happens when you fly through it on a paraglider. Aerology is essential to keeping you safe and helping you pass your flying exams, and diagrams and easy-to-read explanations throughout make everything clear. All the gear you need Understand the difference between different types of paragliders and harnesses. Learn about flying instruments, helmets and reserve parachutes – as well as specialist kit for acro, accuracy, hiking, mountaineering and powered paragliding. Getting started How does a wing fly? What happens on a paragliding training course? How do you safely launch a paraglider in different conditions? Turn? How do you come down? The book answers all the new-pilot questions in a straightforward, easy-to-understand way. Learning about the weather The book is an excellent meteorology primer, explaining weather systems and the art of forecasting. You’ll learn to read the clouds and the sky, how valleys and hills affect the wind, and how to use apps and other technology to your full advantage. Becoming a qualified pilot Learning to fly independently from an instructor is when your learning curve really takes off. So it’s time to learn advanced manoeuvres that will keep you safe in a range of conditions. In the book you’ll learn about advanced training, techniques, and safety clinics. Going places Air law and airspace can be a dry topic, but here the editors have made the essentials really simple and clear so you can stay safe – and legal. Also, find out about the different kinds of instruments available – from basic altimeters to hi-tech flight computers. Getting your licence Paraglider pilot training across the world follows the same basic principles. The book follows the broad teaching curricula of the BHPA (UK), USHPA (USA) and other national paragliding organisations, including Canada, South Africa, Australia and New Zealand, so it’s suitable for pilots worldwide. The story of paragliding From pioneers to world record flights. Learn how paragliding grew from an experimental activity in the French Alps to the incredible adventure sport it is today, enjoyed by an estimated 125,000 qualified pilots worldwide.

Book Description
Low-speed wind-tunnel studies were made of the effects of camber and twist and the effects of aspect ratio on the aerodynamic characteristics of parawings. To determine the effects of camber and twist, tests were made both with the conventional conical-type canopy, which provides camber and washout, and with a cylindrical-type canopy which provides essentially zero camber and twist. With regard to aspect ratio, tests were made of parawings having aspect ratios of 3 and 6; the range was thereby extended well beyond that of previous investigations. The degree to which airfoil and wing theory can be used to predict the aerodynamic characteristics of parawings was also investigated.

Book Description
The report covers the initial evaluation of the National Aeronautics and Space Administration's (NASA) 24-foot limp parawing for use as a manned aerial delivery system. A satisfactory application of the parawing to this use will provide the capability of offset precision aerial delivery of personnel. Aided by a navigational system, the parawing could be employed during night and during conditions of adverse visibility. The primary objective of the evaluation was the acquisition of deployment load data on the parawing. Testing, which included dummy drop tests and live drop tests, was conducted from 16 March 1966 to 20 April 1966. In general, the measured and observed characteristics of the parawing, coupled with the comments of the members of the U.S. Army Parachute Team (USAPT) who flew the wing, indicate that the parawing has potential and merits further investigation. Specifically, the loads were found to be within human tolerance and were no greater than those experienced in jumping conventional parachutes. The glide ratio of the parawing appears to be in excess of 2:1. (Author).
