Book Synopsis Opening Dynamic Characteristics of a 32-ft Ringslot Parachute, Stiffness Index 0.24, and a 45.2-inch Model, Stiffness Index 0.40 by : Helmut G. Heinrich
Download or read book Opening Dynamic Characteristics of a 32-ft Ringslot Parachute, Stiffness Index 0.24, and a 45.2-inch Model, Stiffness Index 0.40 written by Helmut G. Heinrich and published by . This book was released on 1972 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The stiffness characteristics of full size and model parachutes can be expressed as stiffness indices. An example is given in which a conventionally built ringslot model parachute has a stiffness index of 1.0. A very flexible model was developed with 0.4 stiffness index while a geometrically similar 32-ft ringslot parachute had an index of 0.24. The design details of the flexible model are described. The projected area-time history during the inflation of the 32-ft ringslot parachute, obtained from full size parachute tests, were compared with those of the model ringslot parachute with a stiffness index of 0.40. The area-time characteristics of the model were obtained in wind tunnel tests. Both area-time histories are nearly identical.
Download or read book Synthetic Fibers written by Franz Fourné and published by Hanser Gardner Publications. This book was released on 1999 with total page 885 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide to plant design and machinery construction and operation is written by one of the pioneers in the field. It offers a comprehensive overview on processes, machines, and plant layouts for the production of synthetic (man-made) fibers from an engineering point of view. Detailed technical drawings, plus numerous formula and diagrams, illustrate the entire fiber-technical knowledge for the design of various production steps, from raw materials through polymerization, and spinning to textured and technical fabrics. This unique handbook is a treasury of knowledge for the expert, an indispensable adviser in solving day-to-day problems, and a must on the shelf for every library.
Book Synopsis Flexibility as Parameter of Model Parachute Performance Characteristics by : Helmut G. Heinrich
Download or read book Flexibility as Parameter of Model Parachute Performance Characteristics written by Helmut G. Heinrich and published by . This book was released on 1970 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parachute model tests offer the possibilities of efficiently conducting parametric performance studies. Meaningful model experiments must, however, consider besides the effects of Reynolds and Mach Numbers, those of porosity as well as structural characteristics if non-steady processes shall be investigated. In the following the model stiffness index is defined and its effect upon static and dynamic performance characteristics investigated. Quantitative data and stiffness indexes of cloth samples and parachute models are determined. A new technique of construction is described which provides parachute models with a lower stiffness index than previously available. Results of wind tunnel and catapult experiments with parachute models of different stiffness indexes are shown and, when possible, compared with results of full size tests.
