Flight Studies of the Horizontal-Tail Loads Experienced by a Fighter Airplane in Abrupt Maneuvers

Description: Field measurements were made on a fighter airplane to determine the approximate magnitude of the horizontal tail loads in accelerated flight. In these flight measurements, pressures at a few points were used as an index of the tail loads by correlating these pressures with complete pressure-distribution data obtained in the NACA full-scale tunnel. In addition, strain gages and motion pictures of tail deflections were used to explore the general nature and order of magnitude of fluctuating tail loads in accelerated stalls.

Hanford Engineer Works monthly report, July 1944

Description: This progress report discusses activities at Hanford Engineer Works for the month of July, 1944. The organization size increased rapidly in July, jumping from 1384 to 1886, an increase of 502 employees. Shortages existed on special lines such as electricians, instrument mechanics, and power operators. The opportunities to interview and employ Construction personnel improved as the Construction, organization moved past its peak employment figure. 269 houses were completed in Richland and 370 occupancies were reported, reducing the backlog of empty houses due to slow furniture movements. A total of 1530 houses or 35.6% of the village is now occupied. The overall canning yield increased from 63% to 75% while production leveled off at approximately two-thirds of design capacity. The metal machining operation and the test pile operated on a one shift-six day per week basis. The portion of the 100-B Area from the pump house through the filter plant and including the Power House was taken over by Operations on July 25. The Power House in the 200-W Area was started and flushing of process lines with water and steam got under way in the canyon. A new department was formed to control the Protection activities of the plant.

Critical combinations of shear and transverse direct stress for an infinitely long flat plate with edges elastically restrained against rotation

Description: An exact solution and a closely concurring approximate energy solution are given for the buckling of an infinitely long flat plate under combined shear and transverse direct stress with edges elastically restrained against rotation. It was found that an appreciable fraction of the critical stress in pure shear may be applied to the plate without any reduction in the transverse compressive stress necessary to produce buckling. An interaction formula in general use was shown to be decidedly conservative for the range in which it is supposed to apply.
