analysis also found that aft body aerodynamic drag was very sensitive to propulsive design variables (such as fan pressure ratio). Optimizing the configuration as a mul- tidisciplinary coupled system led to a significantly different (better) optimum design point than an uncoupled analysis. While such multidisciplinary coupling will manifest in ways specific to each configuration, this case study illustrates the benefit of using high-fidelity, coupled modeling for analysis and optimization in order to maximize the benefit afforded by electric propulsion. Bauhaus Luftfahrt developed simple low-fidelity methods and conducted broad tradespace exploration studies; unlike all other studies, cash operating cost was con- sidered as an optimization variable [25]. The electric VTOL literature on modeling and simulation may also apply to fixed wing applications in some cases. The Boeing team of Duffy et al. developed an MDAO framework for sizing and tradespace exploration of small eVTOL aircraft. The paper includes a simple methodology for operating cost modeling for electric aircraft, including some low-fidelity estimation of cost savings due to increased reliability [161]. A similar approach was used by Brown and Harris [162]. The Airbus Vahana team posted an open-source conceptual design tool with MDO capability on the web, but has not published on the work in a scholarly forum [163]. A summary of modeling and simulation capabilities, by discipline and project, is shown in Table 6. The cells are color coded to indicate the authors’ assessment of the relative level of fidelity, where red represents the lowest fidelity, and green repre- sents the highest achieved fidelity. It is worth remembering that advanced modeling and simulation capability probably exists in trade secret form within industry, so the published literature may present an incomplete view of the state of the art in electric aircraft modeling. 34PDF Image | Electric, hybrid, and turboelectric fixed-wing aircraft

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
