Water air cross-medium vehicles have the advantage of cross-domain flight and gradually become a research hotspot. However, existing technologies cannot provide better hydrodynamic performance while achieving efficient vehicle efficiency. In this paper, A variant mechanism was designed based on external characteristics submarine to achieve integrated rotor main hull aircraft, ensuring underwater aircraft. tiltable tail ensure stable aircraft in airspace. To feasibility design, computational...
The hydrodynamic coefficients of underwater robots can be used to evaluate their maneuverability and motion stability design controllers, thereby reducing experimental time costs. In this paper, an Autonomous Underwater Vehicle (AUV) with a negative-lift profile is designed. spatially constrained method, combined neural networks, utilized identify all the in standard equations AUV. Subsequently, based on goodness-of-fit, significance evaluated yield simplified equation. Given cost...
Abstract Solar-powered autonomous underwater vehicles (SAUVs) can harness sustainable natural energy, meaning that they are capable of providing long-term mission support. This paper describes ongoing development work on the overall design a SAUV. It outlines goals for vehicle, with particular focus unconventional shape resulting from integration solar panels within body is equipped an array commonly used sensors as its perception system, thus ensuring comprehensive environmental awareness....
Autonomous underwater vehicles (AUVs), as primary platforms, have significantly contributed to surveys in scientific and military fields. Enhancing the maneuverability of autonomous is crucial their development. This study presents a novel vectored thruster an optimized blade design approach meet requirements specially shaped AUV. Determining ideal characteristics involves selecting maximum diameter 0.18 m configuring number blades be four. Furthermore, AUV were set rotate at speed 1400...
Abstract Hydraulic collection has been shown to be a promising technology in deep sea mining. However, the efficiency of hydraulic is affected by many factors. For understanding effect inlets distinct from shapes on collecting efficiency, series upward pumping experiments was conducted spheres. Flow fields at different were described numerical simulation and compared uncover influence inlet shape sphere. The experimental results indicate that straight cylindrical pipe with flanged higher...
The effect of boat-generated waves on mangrove forests could be reflected by width change tidal inlets using satellite image in this study. Our results showed that the distributions zone side were degenerated from 2009 to 2011 Dongzhai Harbor Mangrove Natural Reserve. main reason was strong erosion flat caused generated high speed and frequencies boats for tourists. To protect inlets, drive pass waterway should restricted decreased.
Concentration of 4 heavy metals (Cu, Pb, Zn, Cd) and petroleum hydrocarbon in the surface sediments collected from Chenglingji, Dongting Lake, were quantitatively analyzed. Distribution characteristics possible sources discussed. Methods single-factor index geoaccumulation adopted to evaluate potential ecological risks metal. The results showed that Cd was seriously polluted a strong risk level; Cu, Pb Zn pollution mild Chenglingji Port, Lake. Petroleum content nearshore sediment low exclude...
Galaxolide (1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethyl-cyclopenta-γ-2- benzopyran, HHCB) is recognized as a novel contaminant in water and has potential adverse impacts on aquatic organisms. The toxic effect of HHCB Phanerochaete chrysosporium was investigated by exposure the fungus nitrogen-limited culture medium to various concentrations HHCB. DNA damage P. detected. Comparing with that control, percent polymorphism under different increased, from 21.4% 42.9%. In addition, result UPGMA...
In this paper, the toxic effect of dye wastewater on Phanerochaete chrysosporium was investigated. The DNA damage P. analyzed using AFLP method. Comparing with that in control, percent polymorphism under different concentrations increased, from 17.54% to 53.49%. addition, result UPGMA (un-weighted pair group method arithmetic means) dendrogram showed Simple Matching Coefficient (SM) decreased an increase dyes. Results suggested dyes have at molecular level as environmental pollutants.
