Geology of the Mississippi River Deltaic Plain, Southeastern Louisiana: Volume 1

Geology of the Mississippi River Deltaic Plain, Southeastern Louisiana: Volume 1

Date: July 1958
Creator: Waterways Experiment Station (U.S.)
Description: "The purpose of this report is to consolidate data gathered by the Corps of Engineers in various geologic investigations, and to augment this material with pertinent information garnered from the extensive investigations and studies [of the Mississippi River deltaic plain and its associated offshore area]" (p. 1). The report focuses primarily on those materials that are most important from an engineering standpoint.

Handbook of structural stability part VI : strength of stiffened curved plates and shells

Handbook of structural stability part VI : strength of stiffened curved plates and shells

Date: July 1, 1958
Creator: Becker, Herbert
Description: A comprehensive review of failure of stiffened curved plates and shells is presented. Panel instability in stiffened curved plates and general instability of stiffened cylinders are discussed. The loadings considered for the plates are axial, shear, and the combination of the two. For the cylinders, bending, external pressure, torsion, transverse shear, and combinations of these loads are considered. When possible, test data and theory were correlated. General instability in stiffened cylinders was investigated. For bending and torsion loads, test data and theory were correlated. For external pressure several existing theories were compared. As a result of this investigation a unified theoretical approach to analysis of general instability in stiffened cylinders was developed. (author).

Icing Frequencies Experienced During Climb and Descent by Fighter-Interceptor Aircraft

Icing Frequencies Experienced During Climb and Descent by Fighter-Interceptor Aircraft

Date: July 1, 1958
Creator: Perkins, Porter J.
Description: Data and analyses are presented on the relative frequencies of occurrence and severity of icing cloud layers encountered by jet aircraft in the climb and descent phases of flights to high altitudes. Fighter-interceptor aircraft operated by the Air Defense Command (USAF) at bases in the Duluth and Seattle areas collected the data with icing meters installed for a l-year period. The project was part of an extensive program conducted by the NACA to collect Icing cloud data for evaluating the icing problem relevant to routine operations. The average frequency of occurrence of icing was found to be about 5 percent of the number of climbs and descents during 1 year of operations The icing encounters were predominantly in the low and middle cloud layers, decreasing above 15,000 feet to practically none above 25,000 feet. The greatest thickness of ice that would accumulate on any aircraft component (as indicated by the accretion on a small object) was measured with the icing meters. The ice thicknesses on a small sensing probe averaged less than 1/32 inch and did not exceed 1/2 inch. Such accumulations are relatively small when compared with those that can form during horizontal flight in icing clouds. The light ...
