Investigation of horn balances on a 45 degree sweptback horizontal tail surface at high subsonic speeds

Investigation of horn balances on a 45 degree sweptback horizontal tail surface at high subsonic speeds

Date: December 3, 1948
Creator: Johnson, Harold S & Thompson, Robert F
Description: A wind-tunnel investigation of horn balances on a 45 degree sweptback, semispan, horizontal tail surface was made to determine the effects of horn size and inboard-edge fairing at a Mach number of 0.30 and to determine the effects of compressibility up to a Mach number of 0.89. Presented are lift, drag, pitching-moment, and hinge-moment data and lift and hinge-moment parameters.

Residual stress analysis of overspeeded disk with central hole by x-ray diffraction

Residual stress analysis of overspeeded disk with central hole by x-ray diffraction

Date: July 23, 1948
Creator: Good, James N
Description: An X-ray - diffraction analysis of residual surface stresses after plastic strain was introduced in a parallel-sided 3S-O aluminum disk with a central hole by two types of centrifugal overspeed is reported. Both tangential and radial stresses were generally tensile with large local variations near the hole where surface stresses may have been partly superficial. These stresses were both tensile and compressive dependent on the distance from the disk center when mass compression was effected near the hole.

The effects of high-lift devices on the low-speed stability of a tapered 37.5 degree sweptback wing of aspect ratio 3 in straight and rolling flow

Date: November 9, 1948
Creator: Queijo, M J & Lichtenstein, Jacob H
Description: Contains results of tunnel tests to determine effects of various combinations of split flaps, slats, and nose slats on the stability characteristics of a tapered 37.5 degree sweptback wing of aspect ratio 3 in straight and rolling flow.
