Download or read book The Local Motions of a Payload Supported by a Tritethered Natural Shape Balloon written by Richard C. Leclaire and published by . This book was released on 1973 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report compares the payload motions during flights of a 793 cubic meter (28,000 cubic feet) natural-shape balloon on a tritethered cable array with those using an identical balloon on a single cable. Nominal altitudes were 457 m (1500 ft), 610 m (2000 ft), and 762 m (2500 ft) above ground level at Holloman AFB and White Sands Missile Range, New Mexico. Winds ranged from 0.5 m/sec to 12 m/sec (1 to 23 knots). The payload location relative to the balloon was varied and the balloon was flown with different values of free lift and elevation angles. Target position, tangential speed, and acceleration were determined by using the WSMR cinetheodolite system. Telemetry included pitch and roll gyros, a flux-gate compass, accelerometers, and an anemometer. With both types of cable arrangement, one component of the motion was an oscillation similar in order of magnitude of frequency and orientation to the classic transverse oscillations of a sphere due to periodic vortex shedding in its wake.

Download or read book Motions of a Payload on a Tethered Aerodynamic shape Balloon Using Various Cable Lengths written by Don E. Jackson and published by . This book was released on 1975 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of flight tests of a classic British barrage (kite) balloon was made at White Sands Missile Range in a variety of wind conditions and tether lengths. The report presents the motions of a payload suspended beneath the balloon as measured by ground-based cinetheodolites and balloon-borne sensors. Included in the data are horizontal and vertical trajectories, maximum displacement, pitch and roll angles, ground speed, and acceleration.

Available in PDF, EPUB and Kindle. Book excerpt: The annotated bibliography has evolved from an informal compilation prepared in response to many requests from military and civilian researchers who were planning balloon-borne experiments and searching for data or detailed information concerning some specific aspects of modern scientific ballooning operations. The bibliography consists of three parts: a subject index, an author index, and the bibliography with annotations.
