Glider Development in Germany: A Technical Survey of Progress in Design in Germany Since 1922
This report is a recounting of glider development beginning with the "Vampyr" on up to the present day. The primary purpose is to determine what the fundamental features of the glider are and what the course of its development has been during the thirteen years of activity in motorless flight.

Reduction of Lift of a Wing Due to Its Drag
This analysis computes for a predetermined airfoil and given Reynolds Number the course of the "displacement thickness," i.e., the course of the layer by which the streamlines of the potential flow are pushed away from the wing through the frictional layer. The result is, to a certain extent, a new wing contour.

Weldability of High-Tensile Steels From Experience in Airplane Construction, With Special Reference to Welding Crack Susceptibility
"The concept of welding crack tendency is explained and illustrated with practical examples. All pertinent causes are enumerated, and experimental measures are given through which the secondary effects can be removed and the principal causes analyzed: 1) welding stresses; and 2) material defects. The variations in length and stresses incident to welding a small bar as free weld, with restrained elongation and restrained elongation and contraction, are explored in three fundamental experiments" (p. 1).
