For an intercooled core, the OPR value is no longer constrained by a maximum allowable HPC delivery tempera- ture. Nevertheless, the intercooling process increases the air density in the gas path and as a result the compressor blades tend to become smaller. Losses from tip clearances become increasingly important and a minimum compressor blade height limitation needs to be applied to maintain state of the art compressor ef- ficiency. Core architecture selections for the conventional core set an upper limit to the HPC design pressure ratio that can achieved when driven by a single-stage HPT. With respect to the intercooled core, a two-stage HPT has been assumed to relieve the restriction set on the HPC pressure ratio; the minimum design pressure ratio for the Intermediate Pressure Compressor (IPC) is limited by ic- ing considerations during the descent flight phase. The maximum area variation that may be achieved by the variable area auxiliary nozzle is also constrained by mechanical (and aerodynamic) considerations. Designing a combustor at very low air to fuel ratio levels is also limited by the need for adequate combustor liner film-cooling air as well as maintaining an acceptable temperature traverse quality [8]; this sets an upper bound on com- bustor outlet temperature. Furthermore, a maximum permissible mean metal 157PDF Image | Multi-disciplinary conceptual design of future jet engine systems

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
