The Approximate Analysis of Zero-lift Trajectories by C. P. Hoult Pdf
The gross motion of a ballistic rocket following a zero-lift trajectory during both powered flight and re-entry is discussed with special reference to the importance of the appropriate dimensionless parameters. Approximate solutions are found for the tip-over maneuver, low- and high-altitude powered flight, and re-entry. Of the greatest significance to the rocket dynamicist is that all the above solutions are related to confluent hypergeometric functions with have been used to describe short-period motion in the literature.
Radiation Studies from Nuclear Emulsions and Metallic Components Recovered from Polar Satellite Orbits by Herman Yagoda Pdf
This study discusses two blocks of Ilford G5 emulsions, plus metallic components, that were recovered from the polar orbiting satellites, Discoverer XVII and XVIII. This discussion covers the Class 3+ flare of 12 Nov 1960 in relation to the Discoverer XVII exposure; photographic processing of satellite-exposed emulsions; preliminary cosmic-ray observations on orbited emulsions; and radiochemical analyses of the Discoverer capsules.

Winds and Circulations in the Mesosphere by Thomas J. Keegan Pdf
Some preliminary analysis are presented of the winds and circulations in the mesosphere based upon the first year of data collected by the Meteorological Rocket Network. Differences between winds determined from radar targets released by rockets and those from the conventional balloon technique are discussed briefly.

Some preliminary analysis are presented of the winds and circulations in the mesosphere based upon the first year of data collected by the Meteorological Rocket Network. Differences between winds determined from radar targets released by rockets and those from the conventional balloon technique are discussed briefly. The scale of seasonal, daily, and vertical wind variations is illustrated by wind profiles and time cross-sections. They demonstrate clearly the seasonal reversal of mesospheric winds and the existence of large, wind-speed variations over periods of only several days. They also reveal that vertical wind shears of 0.030 per sec, and probably greater, exist at about 180,000 ft. A relationship is indicated between mesospheric circulation changes and subsequent tropospheric circulation changes. Examples are shown of the circulation over North America in spring and summer at heights up to 180,000 ft. Analysis of rocket wind-data indicates that the techniques are sound and that much can be learned by more intensive analysis. (Author).
