Chapter4. DataAnalysis 63 (a) Isolated, DLR 257 (b) Installed, DLR 423 Figure 4.17: Isolated and installed cutback TPs with FS (DLR 257 and 423), TOB 1250 Hz. Dynamic range of the plot is the absolute SPL maximum. The displacement of some areas causes the comparison plot to have a large dy- namic range. 4.4 Broadband Fan Noise Simulation The broadband noise generation is described in Sect. 3.1.4. Its main purpose is to simulate the typical rearward fan noise from the bypass duct. The test points relevant for this section are shown in Table 4.2 alongside their configuration and flow conditions. Table 4.2: Broadband test points. All tests were carried out on a short-cowl engine with baseline nozzle configuration. DLR TP 306 383 350 444 No Flow Conditions Condition No flow No flow SL SL Flight Stream No No Yes Yes Wing Excitiation No BB Yes BB No BB-A Yes BB-A In order to exemplify and verify the sound generation, tests were run without any additional flow (neither jet nor flight stream). The broadband sound exci- tation of those tests spanned all relevant frequencies and was not limited to a certain frequency range. Employing the usual 20 dB dynamic plot range, only the noise emanating from the speakers is visible on the nozzle exit plane, possess- ing a uniform directivity and vanishing in close proximity to its first occurence,PDF Image | Investigation of wing installation effects on the sound field of a model jet engine

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
