Available in PDF, EPUB and Kindle. Book excerpt: This report covers a two-phase, 7-month research and development program to design and fabricate a prototype cargo-recovery parachute assembly for airdropping heavy unit loads in the order of 50,000-lb. The design study covers the trade-off analysis and cost effectivness aspects for a complete parachute assembly. From these studies, a design analysis and a complete detailed design were made based on the specified performance and design requirements. Use of data reduction on full-scale cargo drops with G-11A parachutes with vent-pull down configuration, scale model wind tunnel tests and parametric studies determined that it is feasible to use a cargo parachute of 135 ft. diam. with a vent-pull down in a cluster of six to recover a load unit of 50,000-lb.

Available in PDF, EPUB and Kindle. Book excerpt: The report presents the results of an in-depth exploratory development study of a parachute retrorocket recovery system for the airdrop of cargo loads weighing up to 50,000 pounds and the results of actual drop tests of loads weighing from 3000 to 35,000 pounds. The study indicates that a parachute retrorocket recovery system is particularly feasible for the recovery of airdrop loads and may prove to be the only practical system for heavy loads, especially if low altitude is a requirement.

This book was released on 1971 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical report presents the results of an in-depth exploratory development study of an airdrop system utilizing the recovery parachutes to extract as well as recover the airdrop load. The purpose of the study was to achieve a low altitude capability by minimizing the altitude loss from the time that the load clears the aircraft until an acceptable impact velocity is achieved. During the study, mathematical models were developed and programmed for computer solution which simulated the operation of an airdrop system. This analytical tool, coupled with experimental data derived from a limited flight test program, was utilized to conceptualize a configuration for an airdrop system and predict its theoretical performance. From these studies emerged an understanding of possible configurations for a low altutude airdrop system employing the recovery parachutes for extraction.

Available in PDF, EPUB and Kindle. Book excerpt: A 26-ft-diameter ribbon parachute deployed using a pilot parachute system has been developed at Sandia National Laboratories for the recovery of a 760-lb payload released at subsonic and transonic speeds. The wide range of deployment dynamic pressures led to the design, utilizing wind tunnel testing and computer simulation, of a unique pilot parachute system verified in full-scale flight tests. Performance data from 20 full-scale flight tests were used to evaluate system performance and structural validity. The concical ribbon parachute design chosen for this development effort follows the practice of previous Sandia National Laboratory parachute development programs for high performance airdropped payloads. The design process for this parachute system included a tradeoff study to evaluate and compare the performance between an equivalent drag area 26-foot-diameter single parachute system and a cluster system of three 14-ft-diameter parachutes. The results showed a small advantage for the cluster system in inflation and initial deceleration characteristics. However, the higher cost, higher weight, greater packing complexity and greater risk involved in the development of the cluster system outweighed the performance advantages and led to the choice of the 26-ft-diameter parachute as the baseline design for the development. This paper describes the design and performance of the 26-ft-diameter parachute which was chosen for the recovery of a 760-lb payload. The results of 20 full-scale flight test of this parachute system are summarized. 8 refs., 13 figs., 2 tabs.
