This book was released on 1964 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research program covers the detailed investigation of gliding parachutes and their necessary guidance and control systems to achieve a controlled approach to a touchdown at a preselected site. Theoretical and analytical investigations have been conducted to determine system feasibility and performance limits; and to establish the configuration of a flexible, self- inflating canopy capable of meeting the program objectives. A series of exploratory wind tunnel tests with small model steerable parachutes has been conducted to substantiate the findings of the analytical investigation and further define the detail design of the most promising configurations. Additional tests with large scale models in the form of tow tests, wind tunnel tests, and free-flight deployment tests, have been conducted to demonstrate aerodynamic characteristics; and to obtain essential data for use as design criteria for an integrated steerable parachute system. The results of this research program, reported herein, has culminated in the design of a flexible, self-inflating, steerable parachute canopy which has demonstrated in wind tunnel tests a maximum lift-to-drag ratio of 2:1; has been deployed in free-flight tests at velocities up to 150 knots; and has demonstrated a turn rate of approximately thirty (30) degrees-per-second.

This book was released on 1966 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: This program covers the detailed investigation of gliding parachutes and their necessary guidance and control systems to achieve a controlled approach to and touchdown at a preselected spot. Theoretical and analytical investigations and exploratory wind-tunnel and truck-tow tests were conducted to establish a flexible and self-inflatable canopy configuration capable of meeting the program objectives. Free-flight tests were conducted to demonstrate the performance of the selected configuration. This report documents the free-flight test phase of the program. Sixteen, 28 and 40 foot steerable parachute canopies were free-flight tested with suspended weights from 198 to 3865 lbs. to obtain deployment, inflation, and performance data. A flexible, self-inflating, steerable parachute was developed which demonstrated a maximum L/D of 2.1 in wind tunnel tests; has been deployed in free-flight tests in sizes up to 40 ft. D(W) at velocities up to 150 knots and altitudes up to 15,000 ft. and demonstrated excellent stability and controllability with turn rate up to 30 degrees per second.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Analytical studies were conducted for the purpose of defining optimum systems for the aerial delivery of payloads in the 35,000 to 70,000-pound range and the aerial retrieval of payloads in the 3,000 to 10,000-pound range. A generalized approach was utilized in the analysis and evaluation of candidate systems for both functions. Included in the study was a definition of requirements for each operational phase, the development of criteria for concept classification and selection, feasibility analyses of candidate concepts, and a comparison of operational characteristics of delivery and retrieval concepts. Selected concepts were employed in the formulation of complete systems, for which detailed performance analyses and evaluations were conducted. Conclusions formed on the basis of the analytical study are presented.

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.
