The present application relates to precision mechanical tools, and more particularly to a combination tool for tensioning a fastener, for example as done when truing and aligning a tension-spoked wheel.
Many precision assembly operations require measuring the amount of tensile strain applied to fasteners. For example,
This turbine differs that has two additional elements - a turbo-expander in the center and jet cuts on blades. The turbo expander absorbs wind energy. Thus the non-working center of the turbine becomes effective. In some versions, the fairing itself will have grooves absorbing wind energy.
Ultra-compact Very Low Frequency (VLF) Communication Systems for Underground, Underwater, and Hypersonic Flight
<Motivation and Innovation>
Radio frequency (RF) technologies have limitations that cannot fulfill specific requirements. For instance, underground and underwater are challenging environments due to the absorption of high frequency electromagnetic (EM) waves in dense media. For hypersonic communications,
