Vertical force-deflection characteristics of a pair of 56-inch-diameter aircraft tires from static and drop tests with and without prerotation

Vertical force-deflection characteristics of a pair of 56-inch-diameter aircraft tires from static and drop tests with and without prerotation

Date: February 1, 1957
Creator: Smiley, Robert F
Description: The vertical force-deflection characteristics were experimentally determined for a pair of 56-inch-diameter tires under static and drop-test conditions with and without prerotation. For increasing force, the tires were found to be least stiff for static tests, almost the same as for the static case for prerotation drop tests as long as the tires remain rotating, and appreciably stiffer for drop tests without prerotation.

Wall Interference in a Perforated Wind Tunnel

Wall Interference in a Perforated Wind Tunnel

Date: May 1, 1957
Creator: Brescia, Riccardo
Description: The theory of cascades, made up of a series of flat plates placed one behind the other, is extended to the case where the impinging stream is not uniform, and the deduced properties of this cascade-flow are then applied to the study of the wall interference between such as cascade-like boundary and a vortex-source type of singularity. It is shown that the induced velocities, produced by the presence of such a wall, are equal to what is obtained by action of a suitably chosen 'reflected' singularity situated on one side of the wall, together with the action of another suitably chosen 'transmitted' singularity placed on the other side. The concepts of a reflection factor and a transmission factor are introduced to characterize various types of tunnel boundary, whether this is composed of solid wall, open and closed sequences, or just a free fluid surface. These ideas are then extended to cover the situation in which a pair of such walls are allowed to coalesce, especially in the event that one of the walls consists of open and closed portions and the other is a fluid surface. This latter particular combination of boundaries is called a perforated wall. Finally, the interference ...

A wide-frequency-range air-jet shaker

A wide-frequency-range air-jet shaker

Date: June 1, 1957
Creator: Herr, Robert W
Description: This paper presents a description of a simple air-jet shaker. Its force can be calibrated statically and appears to be constant with frequency. It is relatively easy to use, and it has essentially massless characteristics. This shaker is applied to define the unstable branch of a frequency-response curve obtained for a nonlinear spring with a single degree of freedom.
