The split-type conical nozzles with replaceable exit sections with diameters of 30, 40 and 50 mm were designed and produced from steel by machine turning. In addition, the replaceable output parts of the nozzles with the same diameters were produced by additive technology (fused deposition manufacturing) from ABS plastic. In the acoustic anechoic chamber, the noise measurements of a single-stream cold air jet for all the nozzles at jet velocities in the range of 0.3-0.7 Mach numbers were carried out. The noise measurements were performed on distance of 2 m from the center of the nozzle exit section at angles from 30 to 105o. For different directions of noise radiation and different velocities of the jet, the power spectral density and overall sound pressure level were determined. The obtained results demonstrates that the jet noise for nozzles with diameter of 40 and 50 mm from steel and ABS plastic differs by no more than 1 dB, which is within the measurement error for these types of experiments. The nozzles with diameter 30 mm have a higher difference in noise, which can be explained by the more sensitivity of a nozzle with a small diameter to the deviations of geometric parameters when it produced by additive technology.

Research Findings

The purpose of this study is to analyze the direct economic impacts of the world’s top five busiest airports in 2018 as they contribute to the economic well-being of the larger communities they serve. This study uses a descriptive case-study methodology since the direct economic impacts of the world’s top five busiest airports are going to be studied in a case-by-case with an intention of reporting the research findings that are not related to specific variables. Amongst the 17,678 commercial service airports in the world, Hartsfield-Jackson Atlanta International Airport (USA), Beijing Capital International Airport (Peoples Republic of China), Dubai International Airport (United Arab Emirates), Los Angeles International Airport (USA), and Tokyo Haneda International Airport (Japan) have been ranked respectively as the top five busiest airports in the world on the basis of passenger volume handled in 2018. The research findings indicate that these airports have tremendously benefited their respective communities in terms of employment generation, income generation, and total direct economic impacts. These airports have generated a total of $181.4 billion worth of direct economic benefits to their respective communities and regions.
