Download or read book Technical Report on Vortex Ring Parachute Wind Tunnel Tests at United Aircraft Corporation written by David T. Barish and published by . This book was released on 1959 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: The program consisted of testing of full scale parachutes in the 33 foot square settling section, and the measurement of the deployments of deceleration chutes in the 18 foot octagonal test section. Drag measurements on two versions of the Vortex Ring Chute 21.7 feet and 32.5 feet in diameter gave values of drag coefficient, more than 1.8 times that measured with a 28' diameter flat circular chute in the same test section. Correlations with small scale wind tunnel tests are also included. A large number of deployments of the 260" diameter drag chutes were conducted in the test section at speeds from 50 mph to 187 mph. Dynamic force measurements indicated rapid deployment, low shock factor and stable operation. A new pilot chute installation gave good deployment characteristics and stable operation.

This book was released on 1959 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wind tunnel tests were conducted of a large number of configurations of the Vortex Ring Parachute. These produced data for evaluating the effects on performance of porosity, a new panel geometry, rigging variations, four pilot chute configurations, three swivels, a flare model, the wake of a large disk placed upstream, cyclic pitch control, and ground effect. Detailed data were obtained from the flow field behind the chute, by smoke tunnel studies and velocity surveys. In addition, the effect on performance of putting slits in a standard 40" pilot chute to provide rotation was measured.

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.

Available in PDF, EPUB and Kindle. Book excerpt: A brand-new edition of the classic guide on low-speed wind tunnel testing While great advances in theoretical and computational methods have been made in recent years, low-speed wind tunnel testing remains essential for obtaining the full range of data needed to guide detailed design decisions for many practical engineering problems. This long-awaited Third Edition of William H. Rae, Jr.'s landmark reference brings together essential information on all aspects of low-speed wind tunnel design, analysis, testing, and instrumentation in one easy-to-use resource. Written by authors who are among the most respected wind tunnel engineers in the world, this edition has been updated to address current topics and applications, and includes coverage of digital electronics, new instrumentation, video and photographic methods, pressure-sensitive paint, and liquid crystal-based measurement methods. The book is organized for quick access to topics of interest, and examines basic test techniques and objectives of modeling and testing aircraft designs in low-speed wind tunnels, as well as applications to fluid motion analysis, automobiles, marine vessels, buildings, bridges, and other structures subject to wind loading. Supplemented with real-world examples throughout, Low-Speed Wind Tunnel Testing, Third Edition is an indispensable resource for aerospace engineering students and professionals, engineers and researchers in the automotive industries, wind tunnel designers, architects, and others who need to get the most from low-speed wind tunnel technology and experiments in their work.

This book was released on 1972 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 28-ft solid flat parachute, United States Air Force Standard C-9 canopy was deployed from its deployment bag in a wind tunnel running at speeds of 115, 150, and 200 fps. By means of electronic instrumentation the impulses were recorded that developed when the risers and suspension lines are disengaged from their ties and stow loops. The disengagement impulses were repeatable, and their numerical value was established and confirmed. The influence of the impulses upon the velocity of the moving mass is significant.

This book was released on 1991 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A plastic annular parachute model will be tested in the U.S. Army Aviation Systems Command Aeroflightdynamics Directorate (AVSCOM/AFDD) wind tunnel at the NASA Ames Research Center in Moffett Field, California. The data from the wind tunnel test will be used to verify results obtained from the computational fluid dynamics program SALE "Simplified Arbitrary Lagrangian-Eulerian" (which is currently being modified by the Engineering Technology Division (ETD) of the Aero-Mechanical Engineering Directorate (AMED) at Natick to improve the prediction of flow fields around parachutes). In this report the parachute model test setup is analyzed to determine the possibility of failure during the wind tunnel test.
