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.

World famous competitive skydiver and coach Dan Brodsky-Chenfeld presents proven tools and techniques for success and explains how they can be used in everyday life. Dan survived a plane crash from which sixteen of the twenty-two people on board were killed. He was left critically injured and woke up from a six-week-long coma with a broken neck, broken skull, severe head trauma, a collapsed lung, and other serious internal injuries. Against all odds, Dan recovered and went on to become one of the greatest competitive skydiver in the world. With the love and support of friends and family, Dan was able not only to resurrect his life but return to skydiving to achieve greater heights than he could have ever imagined. His techniques and methods for excelling are applicable to all people, no matter their goals. Dan uses his experiences to teach the lessons he’s learned—as a competitor, coach, business owner, father, and husband—to help others achieve their dreams, overcome obstacles, and reach their peak performance.
