Download or read book An Analytical Study of Stable Cargo Platforms for Single and Multiple Parachute Systems written by Helmut G. Heinrich and published by . This book was released on 1964 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was made to determine a suitable parachute-platform combination for a retro rocket assisted cargo delivery. The minimum deployment altitude has been determined for a particular configuration. The necessary rocket thrust has been determined and presented as functions of several system parameters. Experiments were conducted with several conventional parachutes in connection with a particular platform-load combination. A particular configuration, possessing the desired degree of stability, is discussed.

This book was released on 1968 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cargo platform used with a single G-11A parachute supports various payload shapes and sizes. The drag of the platform model was, therefore, measured with three different simulated loads as well as without load.

This book was released on 1968 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drag areas necessary to determine the deployment characteristics of various man-carrying and cargo parachute systems are found in wind tunnel tests and surveys of existing literature. Results include the drag areas of parachute deployment bags, cargo platforms and containers, and the falling human body. (Author).

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.
