Stresses Around Rectangular Cut-outs in Skin-stringer Panels Under Axial Loads - 2 by Paul Kuhn,John Edward Duberg,Edwin M. Moggio,Simon H. Diskin Pdf

The calculation of the stresses around cut-outs is discussed on the basis of a simplified application of the shear-lag theory previously published. Experimental stringer strains were measured around a systematic series of cut-outs. The test results indicate that the proposed method of calculating the stringer stresses is acceptable as a basis for stress analysis. A few measurements were made of shear stresses in the sheet, but a separate experimental investigation on these stresses is desirable because their maximum values are too highly localized for strain readings with ordinary gage lengths.

A Method for Calculating Stresses in Torsion-box Covers with Cutouts by Richard Rosecrans Pdf

Stresses in the covers of torsion boxes containing large cutouts are found by changing half of the symmetrical uncut portion of the cover into three stringers carrying direct stress and intermediate cover material carrying shear stress. Illustrative examples are solved and the results are compared with experimental values. For one example, the results are compared with a more detailed numerical method of analysis. The agreement between theory and experimenbt is satisfactory in all cases except those with very large cutouts and flexible bulkheads.

Effect of Brake Forming in Various Tempers on the Strength of Alclad 75S-T Aluminum-alloy Sheet by Walter Woods,George J. Heimerl Pdf

Results of presented of tests to determine the effect of brake forming in various tempers on the strength of Alclade 75S-T aluminum-alloy sheet in the direction parallel to the brake. The tensile and compressive strengths of Alclad 75S-T sheet, formed in the O and W tempers, were either increased or little affected as compared with those of similarly treated unformed material. When Alclad 75S-T sheet "as received" was formed, however, the tensile yield stress was reduced about 7 percent for the with-grain direction and 1 percent for the cross-grain direction, whereas the tensile ultimate and compressive yield strength stresses were increased somewhat. The elongation was always slightly reduced as a result of forming.

Method for Calculating Lift Distribtutions for Unswept Wings with Flaps Or Ailerons by Use of Nonlinear Section Lift Data by James C. Sivells,Gertrude C. Westrick Pdf

A method is presented for calculating lift distributions for unswept wings with flaps or ailerons using nonlinear section lift data. This method is based upon lifting-line theory and is an extension to the method described by NACA Report 865. Simplified computing forms containing detailed examples are given for both symmetrical and asymmetrical lift distributions. A few comparisons of experimental and calculated characteristics are also presented.

Propeller-loudness Charts for Light Airplanes by Harvey H. Hubbard,Arthur A. Regier Pdf

Calculations of the rotational-noise and vortex noise loudness levels at distances of 300 and 1000 feet have been made for a large number of propellers in forward flight of 50 to 200 miles per hour and for engine ratings of 100 to 300 horsepower. Propellers of two, four, six, and eight blades, diameters of 6, 8, and 10 feet, and rotational speeds of 1000 to 2000 rpm are considered. Calculated results are presented in chart form for convenience of designers of propellers for applications in which loudness is an important consideration.
