Book Description
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.

Book Description
All available experimental values of extraction time, deployment time, opening time, and effective drag coeficient of standard serial delivery systems have been gathered and reduced to comparable conditions. A study has been made to determine the governing parameters in the delivery sequence, and representative values of these parameters have been determined through statistical analysis where possible.

Book Description
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.

Calculated Values of Transient and Steady State Performance Characteristics of Man-carrying, Cargo, and Extraction Parachutes

Category : Airdrop
Languages : en
Pages : 80
Book Description
Opening shock, snatch forces, opening times, rates of descent, and down times of a number of man-carrying, cargo, and extraction parachutes are calculated on the basis of analytical equations and certain other assumptions. Comparisons of the calculated data with full scale experimental values are somewhat limited, but show reasonable agreement when available. This report represents a first step in an attempt to catalog full scale experimental values from which, eventually, more exact analytical methods can be derived.
