Recovery System Design Guide

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.

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.

The care that a patient receives in the first hours after surgery is crucial to minimizing the risk of complications such as heart attacks, pneumonia, and blood clots. As the patient awakes from their drug-induced coma, it takes time for them to metabolize and excrete these drugs, during which period they remain unable to care for themselves, and at increased risk of harm. The recovery room staff must manage both comatose and physiologically unstable patients, and deal with the immediate post-operative care of surgical patients. The fifth edition of this popular book provides nurses, surgeons and anaesthetists with clear guidance on how to manage day-to-day problems and how to make difficult decisions. Previous editions of this book have established it as the definitive guide to setting-up, equipping, staffing, and administering an acute care unit. It includes basic science such as physiology and pharmacology, specific symptoms including pain and vomiting, and has chapters devoted to the unique post-operative needs of individual types of surgery. This new edition brings this important text up to date and new drugs and techniques for monitoring are described. A new section looks ahead to the future development and design of recovery rooms and how they can contribute to patient well being.
