Towards the optimal 2020 ducted turbofan Konstantinos G. Kyprianidis With potential block fuel benefits from improving propulsive efficiency being rather mild, it is worth investigating if the introduction of heat-exchanged cores could change this picture. In the next section, a back to back comparison will be carried out between a conventional core and an intercooled core turbofan engine with year 2020 entry into service level of technology for long range applications. The effects of introducing intercooling will be assessed with respect to improving engine fuel efficiency. Differences in the optimal specific thrust levels between the two configurations will be discussed. 7.2 Optimising a turbofan engine In Chapter 6, a comparison was carried out between a conventional core and an intercooled core turbofan engine with year 2020 entry into service level of technology for long range applications. Both configurations had the same fan diameter and were designed to meet the same thrust requirements. An attempt will be made here to re-optimise those powerplants using TERA2020 by allowing the specific thrust (and hence the propulsive efficiency) to vary. Rather than setting fixed thrust requirements, the rubberised wing aircraft model will be fully utilised instead. The engine/aircraft combination will be optimised to meet a particular set of customer requirements i.e. payload-range, take-off distance, time to height and time between overhaul. It is expected that different conclusions will be drawn when comparing the two powerplants at their optimal specific thrust levels. 7.2.1 Design space constraints For every engine design there are numerous practical limitations that need to be considered. The design space constraints set for this study are given in Table 7.1 and are considered applicable for a year 2020 entry into service turbofan engine. A large amount of information, in spreadsheet format, is provided in Appendix B on the choice of design variables for the optimisation process. For a conventional core the High Pressure Compressor (HPC) delivery tempera- ture, and hence the engine Overall Pressure Ratio (OPR), is typically constrained by the mechanical properties of the HPC disc or HPC rear drive cone or High 156PDF 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
