Download or read book Wind Tunnel and Full scale Forces on Rocket Sleds written by Daniel J. Krupovage and published by . This book was released on 1967 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vertical quasi-steady state forces on three dual rail rocket sleds, which were predicted using wind tunnel data, are compared with those measured on the Holloman Test Track. A description of the magnitude and character of the oscillatory forces is also presented. This is the first such comparison since the advent of rocket sled testing. Wind tunnel force tests on the three rocket sleds indicated that aerodynamic forces would be of sufficient magnitude to warrant consideration in structural design. The forces measured during the track tests indicated that the aerodynamic contribution was the dominant component to the vertical quasi-steady state force in the supersonic regime. The results of full-scale investigations showed implicitly that when the sleds experienced considerable aerodynamic forces, the wind tunnel data agreed fairly well with the forces measured on the rocket sled. The quasi-steady state vertical forces were predicted, using wind tunnel data, to within 3,000 pounds for loads between 12,000 and 32,000 pounds. (Author).
Download or read book Force Measurement on Rocket Sleds written by William E. Baker and published by . This book was released on 1966 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods were developed for measurement of specific components of forces acting on rocket sleds during runs. The forces acting on the sleds for which the instrumentation was developed to measure were the thrust forces from the pusher, the braking forces, and forces acting on the slipper by the track. The methods of measuring the forces included instrumentation of the existing sled structures with strain gages and use of specially developed force transducers which were mounted on the slippers. For both force measurement methods, static calibration procedures were used. The transducer developed was a three component force transducer, measuring two orthogonal components of force and one moment component. Two of these transducers were manufactured and sent to Holloman Air Force Base for use. In addition to the development of methods of measuring forces, the contractor consulted with the Track Test Directorate on problems related to force systems acting on sleds and behavior of the sled due to the force systems. Descriptions of this work are included. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: High speeed impact testing is a branch of environmental testing that lends itself well to the use of rocket sleds. Two types of impact testing are commonly used. The first method, standard impact testing, consists of accelerating the test item to the desired velocity and impacting it into a stationary target. The second method, called turnaround testing, consists of propelling the target into a stationary unit. In order to utilize the advantages of standard testing, it is necessary to be able to record high frequency data from the impact by communicating with the test item carried on the sled. The screen box technique works so well in the classical usage that it was decided to modify the technique slightly and investigate the possibility of transmitting high frequency data generated on the rocket sled through screen boxes to a ground-based recording station located near the track. In order to investigate the above uncertainties, several rocket sled tests were conducted. Based on the tests and a vast log of past experience using screen boxes to supply electrical communication with rocket sleds traveling at velocities up to Mach 3.5 and three highly successful high frequency data tests at speeds near Mach 5, it is believed that high frequency data generated during a rocket sled impact of any velocity achievable at Sandia can be transmitted to recording stations through a conventional rocket sled screen box system. It has been shown that the presence of a rocket sled traveling at hypersonic velocities through a screen box does not degrade, distort, or otherwise alter data being transmitted through the screen box. Additionally, no dropouts or loss of signal of any type was in evidence while using screen boxes as data links.

This book was released on 1967 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Velocity versus coast distance measurements on one monorail rocket sled were conducted to obtain quantitative information on the braking effectiveness of an extendible aerodynamic drag brake. The data were obtained by means of ribbon frame cameras and reduced to the form of drag coefficients for the rocket sled and aerodynamic drag brake. The drag brake as described has a drag coefficient of approximately 1.68 in the subsonic regime and approximately 1.8 in the supersonic regime. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The best backyard experiments for hands-on science learning The Ultimate Book of Saturday Science is Neil Downie's biggest and most astounding compendium yet of science experiments you can do in your own kitchen or backyard using common household items. It may be the only book that encourages hands-on science learning through the use of high-velocity, air-driven carrots. Downie, the undisputed maestro of Saturday science, here reveals important principles in physics, engineering, and chemistry through such marvels as the Helevator—a contraption that's half helicopter, half elevator—and the Rocket Railroad, which pumps propellant up from its own track. The Riddle of the Sands demonstrates why some granular materials form steep cones when poured while others collapse in an avalanche. The Sunbeam Exploder creates a combustible delivery system out of sunlight, while the Red Hot Memory experiment shows you how to store data as heat. Want to learn to tell time using a knife and some butter? There's a whole section devoted to exotic clocks and oscillators that teaches you how. The Ultimate Book of Saturday Science features more than seventy fun and astonishing experiments that range in difficulty from simple to more challenging. All of them are original, and all are guaranteed to work. Downie provides instructions for each one and explains the underlying science, and also presents experimental variations that readers will want to try.
