Abstract:
An illustrative example container includes a plurality of internal support members having a surface contour that at least approximates a minimum surface. The plurality of internal support members collectively provide structural support for carrying loads on the container. The plurality of internal support members collectively establish a plurality of cavities for at least temporarily containing fluid. An outer shell is connected with at least some of the internal support members. The outer shell includes a plurality of curved surfaces. The outer shell encloses the cavities.
Abstract:
A pressure vessel configured to store a pressurized fluid is provided including a plurality of lobes. Each lobe includes at least one vertically arranged interior wall. The plurality of lobes are positioned in a side by side configuration such that a first interior wall of a first lobe is positioned adjacent a second interior wall of a second adjacent lobe. The first interior wall and the second interior wall are configured to contact one another at a first point of tangency. A first tangent intersects the first lobe at the first point of tangency and a second tangent intersects the second lobe at the first point of tangency. The first tangent and the second tangent are separated by about 120 degrees.
Abstract:
A method for peening a surface of a material is disclosed. The method may include producing repeated, separated and high speed liquid drops and moving the liquid drops across the surface to be peened. The liquid drops are essentially free of air bubbles and the velocity of the liquid drops is at least 500 ft/sec. A peening apparatus to produce repeated, separated and high speed liquid drops is also disclosed. The apparatus may comprise a storage tank, a nozzle, a pump, an accumulator, a regulator and an actuator. The apparatus may control the volume and velocity of the produced liquid drops as well as the frequency of the liquid drop production.
