Scientists are using human occupied vehicles to explore underwater environments. There several mechanical features used in the design of vehicles. These primarily based on environmental factors such as high external pressure, low temperature, and corrosion resistance. In this paper, rated for 6,000 m depth studied, including Alvin, Jiaolong, MIR-1/MIR-2, Nautile, Shinkai 6500, well at 11,000 de...

Steam Turbines are devices used to convert thermal energy of steam into mechanical energy, which may be used to produce Electrical Energy. Steam turbine generator units are being used extensively all over the world for generation of electric power and for co-generation of steam and power. Contact pressure and pretension in bolts-analysis has been made easier in recent years due to the availabil...

Nanocomposites are being studied for their mechanical, thermal, and water absorption capabilities. Polylactic acid/chitosan blends have been extensively physical, morphological properties. Although the three materials blended, no research has done on mechanical or properties of PLA/CS/TiC NPs. PLA/CS bonding is quite deprived, thus researchers trying to improve it by introducing TiC NPs; this w...

Abstract As the main load-bearing component of aero-engine system, thin-walled casings have characteristics large size, complex structure, thin wall, and area. In addition to harsh working environment, it is necessary study applicable preventive measures contain high-energy fragments ensure flight safety. The load formed by axial impact circumferential torsion exerted turbine rotor on exhaust c...

Abstract This study aimed to examine the effect of shortening effective heat treatment time by 15 minutes for finely and coarsely chopped sausages canned meat in pieces packed polyamide casings with diameters 75 90 mm. Product safety was ensured accordance legislation producer food system. Optimization led a decrease p-values (diameter 90: 148.8 → 97.64 minutes; diameter 75: 111.2 58.4 min), co...

Nowadays, wind energy is one of the most cost-effective and environmentally friendly energies in high demand due to shortages fossil fuels necessity reduce global carbon footprint. One main goals turbine development increase power output either by increasing blade swept area or velocity wind. In this article, a proprietary augmentation system was introduced vertical axis turbines (VAWT) free st...
