Download or read book Radial Reefing Method for Accelerated and Controlled Parachute Opening written by Calvin K. Lee and published by . This book was released on 1994 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Future Army airdrop systems will require aerial insertion of cargo and personnel from low altitudes to minimize ground-fire hazards. A radial reefing method was developed as a potential candidate to meet this requirement. The radial reefing method involves selecting equally spaced radials of a parachute canopy and reefing these radials near the skirt; concurrently, the canopy fabric adjacent to the reefed radials is puckered. Reefing the canopy this way creates large fabric pockets near the skirt during initial canopy inflation, resulting in accelerated and controlled parachute opening. This was confirmed by full-scale air drop testing using single Army personnel and cargo parachutes. In addition to demonstrating promises for single-canopy low-altitude airdrop applications, the radial reefing method also shows potential to improve clustered parachute opening by minimizing canopy enfolding and slumping.

Download or read book Controlled Opening Method for Clustered Parachutes written by Calvin K. Lee and published by . This book was released on 1992 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a method for achieving simultaneous opening of clustered parachutes. The method involves connecting and partially reefing the parachutes in a cluster during the initial stage of the opening so that they open together as a single parachute; they are then disconnected and disreefed at almost full inflation, thereby controlling and opening the parachute simultaneously. This method, called the controlled opening method, was tested with clusters of 64-ft-diam G-12 cargo parachutes, 100-ft-diam G-11 cargo parachutes, and 28-ft-diam C-9 personnel parachutes. Their openings were significantly improved when compared to the openings of these clusters without using the controlled opening method.

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.
