Available in PDF, EPUB and Kindle. Book excerpt: The Aerodynamic Deployable Decelerator Performance-Evaluation Program (ADDPEP) aims to advance the state of the art by developing the most effective analytical and empirical techniques for designing aerodynamic deployable decelerators and for evaluating these engineering techniques through wind-tunnel and free-flight tests. During ADDPEP Phase 2, two types of decelerators were investigated: large reefed supersonic parachutes and raminflated balloon-type BALLUTEs. The areas investigated included analytical and engineering design, material capabilities, fabrication techniques, and wind-tunnel and free-flight tests. Free-flight tests were performed on a hemisflo parachute having a nominal 16-ft-diameter canopy, a 10-percent extended skirt, and a 14-percent porosity. This design was tested for 200,000-lb opening loads, deployment Mach numbers were 1.50, 1.63, and 1.84 at altitudes of 13,700, 15,500, and 10,500 ft, respectively. The results confirmed that this parachute has excellent aerodynamic characteristics and adequate strength. Five-foot-diameter BALLUTEs, both textile and metal, were fabricated. These were designed for a broad spectrum of deployment conditions ranging from Mach 2.7 at 73,000 ft to Mach 10 at 225,000 ft. The textile BALLUTEs were wind-tunnel and free-flight tested; the metal BALLUTEs were wind-tunnel tested only. Flight tests were limited to Mach 9.7, and wind-tunnel tests to Mach 3. The flight test data supported wind-tunnel data, which indicated that excellent stability and structurally adequate designs can be attained with five-foot-diameter BALLUTEs.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this program is to advance the state of the art by using analytical and engineering techniques for designing aerodynamic deployable decelerators. Three classes of decelerators - small supersonic parachutes, ram- air-inflated BALLUTEs, and large high-dynamic-pressure parachutes were investigated. Free-flight tests using a newly developed GAC missile system and wind-tunnel tests in the full-scale propulsion wind-tunnel facility at Arnold Research Center were conducted. The results indicated that the engineering techniques that were developed led to improved decelerators and that an improved free-flight test capability was established.

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.

Book excerpt: In the development of a computerized data catalog and data retrieval system for deployable aerodynamic decelerators, the results were twofold: (1) a list of parameters which completely define the information pertinent to these decelerators; and (2) a data base (the structure to arrange the data elements making up a unit of information) and the computer programs to manipulate the data base. The combination of these results constitutes a system to store and retrieve by computer techniques all data related to deployable aerodynamic decelerators.

Available in PDF, EPUB and Kindle. Book excerpt: Acronym agglomeration is an affliction of the age, and there are acronym addicts who, in their weakness, find it impossible to resist them. More than once in recent months my peers have cautioned me about my apparent readiness to use not only acronyms, but abbreviations, foreign isms, codes, and other cryptic symbols rather than common, ordinary American words. Many among us, though, either have not received or have chosen to ignore such advice. As a consequence, what we write and speak is full of mystery and confusion. It is then for the reader and listener and for the writer and speaker that Reta C. Moser has compiled this guide. Its effective application to the art of communication is urged. Such use should help avoid many of the misunderstandings involving terminology which occur daily. Although such misunderstandings are certainly crucial in humanistic and social situations, they are often of immediate import and the trigger to disaster in scientific, technical, and political situations. Some 15,000 acronyms and 25,000 definitions are provided (a 50- and 47 -percent increase over the 1964 edition!), with due credit to Miss Moser's diligence in making the compilation and with the acknowledgment that the acronymical phenomenon is very much with us. This edition, like the first, is certain to be of value to writers, librarians, editors, and others who must identify and deal with acronyms.

Couch and published by . This book was released on 1975 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was conducted at Mach 1.80 in the Langley 4-foot supersonic pressure tunnel to determine the effects of variation in reefing ratio and geometric porosity on the drag and stability characteristics of four basic canopy types deployed in the wake of a cone-cylinder forebody. The basic designs included cross, hemisflo, disk-gap-band, and extended-skirt canopies; however, modular cross and standard flat canopies and a ballute were also investigated. An empirical correlation was determined which provides a fair estimation of the drag coefficients in transonic and supersonic flow for parachutes of specific geometric porosity and reefing ratio.
