Download or read book Snatch Force During Lines first Parachute Deployment written by Earle K. Huckins (III.) and published by . This book was released on 1971 with total page 2 pages. Available in PDF, EPUB and Kindle. Book excerpt: Snatch force is generally considered to be the maximum suspension-line tension at the vehicle during the deployment process prior to canopy inflation. For a canopy-first type of deployment, the maximum tension is generated immediately after the decelerator is completely extended. However, for a lines-first deployment, the maximum tension gnerally occurs as the canopy skirt emerges form the deployment bag.

Download or read book The Effect of Line Disengagement Impulses Upon the Parachute Snatch Force written by Helmut G. Heinrich and published by . This book was released on 1966 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theory of parachute snatch force calculation incorporating the effect of the line disengagement impulses is developed and used to calculate snatch forces of the 28-ft solid flat circular parachute, C-9, for cases for which the results of numerous field tests are available. The calculated forces agree satisfactorily with the field test results. Further calculations with the same theory, however, without consideration of disengagement impulses showed consistently higher forces than the field tests results. This indicates that the disengagement impulses are significant contributions in the calculation of parachute snatch forces. Since the improved method of calculation provides the field tests fitting results, the benefits resulting from the disengagement impulses should be considered in the design of parachute deployment bags.

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 Parachute Recovery Systems written by Theo W. Knacke and published by . This book was released on 1992 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this manual is to provide recovery system engineers in government and industry with tools to evaluate, analyze, select, and design parachute recovery systems. These systems range from simple, one-parachute assemblies to multiple-parachute systems, and may include equipment for impact attenuation, flotation, location, retrieval, and disposition. All system aspects are discussed, including the need for parachute recovery, the selection of the most suitable recovery system concept, concept analysis, parachute performance, force and stress analysis, material selection, parachute assembly and component design, and manufacturing. Experienced recovery system engineers will find this publication useful as a technical reference book; recent college graduates will find it useful as a textbook for learning about parachutes and parachute recovery systems; and technicians with extensive practical experience will find it useful as an engineering textbook that includes a chapter on parachute- related aerodynamics. In this manual, emphasis is placed on aiding government employees in evaluating and supervising the design and application of parachute systems. The parachute recovery system uses aerodynamic drag to decelerate people and equipment moving in air from a higher velocity to a lower velocity and to a safe landing. This lower velocity is known as rate of descent, landing velocity, or impact velocity, and is determined by the following requirements: (1) landing personnel uninjured and ready for action, (2) landing equipment and air vehicles undamaged and ready for use or refurbishment, and (3) impacting ordnance at a preselected angle and velocity.
