U.S. NAVY STRUCTURES. ANNEX 3.2 OF SCIENTIFIC DIRECTOR'S REPORT OF ATOMIC WEAPON TESTS AT ENIWETOK, 1951 (open access)

U.S. NAVY STRUCTURES. ANNEX 3.2 OF SCIENTIFIC DIRECTOR'S REPORT OF ATOMIC WEAPON TESTS AT ENIWETOK, 1951

Structures are subjected to a 50-kt blast, in order to obtain fundamental data on structures subjected to blast loading, to observe the response of the structures under this loading, and to determine the relative blast-resistance merits of several structural types. Modes of failure are determined. Shaped structures are found to be superdor to rectangular structures. Earth cover for the structures is also found to increase the blast resistance. It is found that standard Navy heavy bomb-proof structures with modifications can withstand a near-surface atomic burst at ground zero. (T.F.H.)

F.C.D.A. Family Shelter Evaluation (open access)

F.C.D.A. Family Shelter Evaluation

In order to determine the effects of atomic explosions on small civil defense shelters for family use, 29 simple structures were built along an arc 1200 ft from the target point and exposed to Buster Bursts B, C, and D. The structures were of four basic types; covered-trench, metal-arch, wood-arch, and basement lean-to. Because of poor cohesive properties of the soil, much of the earth cover on the shelters was removed by the first shot. Since test procedures prevented restoration of structures and replacement of cover after each blast, test results were materially affected. Partly above-grade cover-trench shelters provided less protection against blast than belowgrade cover-trench shelters and were much less desirable as protection against gamma radiation. Metal-arch shelters set in concrete appeared to have good potentialities with minor design modifications. Wood-arch shelters as designed, proved to be unsuitable substitutes for metalarch shelters. No worthwhile information was obtained on basement lean-to shelters. Unusual conditions disclosed design deficiencies in entrance construction, front, and end sections, and effective earth cover. Small shelters are potentially capable of meeting requirements of civil defense. (auth)

Reciprocity relations in aerodynamics (open access)

Reciprocity relations in aerodynamics

From Introduction: "The purpose of the present paper is twofold. First, a close connection will be established between reverse-flow theorems in subsonic and supersonic, steady-state wing theory and known reciprocity relations between two solutions of the equation the flow field."

A pressure-distribution investigation of a fineness-ratio-12.2 parabolic body of revolution (NACA RM-10) at M = 1.59 and angles of attack up to 36 degrees (open access)

A pressure-distribution investigation of a fineness-ratio-12.2 parabolic body of revolution (NACA RM-10) at M = 1.59 and angles of attack up to 36 degrees

Report presenting a pressure-distribution investigation of a parabolic body of revolution with a fineness ratio of 12.2, which was performed in the 4- by 4-foot supersonic tunnel at Mach number 1.59 and Reynolds number 3.6 x 10(sub 6), based on body length, for a range of angles of attack. Results regarding basic pressures, aerodynamic coefficients, asymmetrical pressures, comparison of experimental and theoretical pressures, artificial roughness, section coefficients, and body coefficients are provided.

The Effects of a Small Jet of Air Exhausting From the Nose of a Body of Revolution in Supersonic Flow

Report presenting the results of an investigation to determine the effects of a small jet of air exhausting from the nose of an elliptical body of revolution upon boundary-layer transition and the viscous, pressure, and total drag of the forebody at three body stations at Mach number 1.62. The jet effects on body pressure, pressure variations, boundary-layer transition, and total drag are provided.

[Photograph 2012.201.B0225.0520]

Photograph taken for a story in the Oklahoma Times newspaper. Caption: "If you are baffled by the intricacies of this year's election between our two major parties, consider the plight of Northwestern State College student Chun Wang Lin and his people in Korea. A few years ago they had only 100 parties and still have 10 or more today."
