Authors:Mehmet Gürsoylu; Ahmet Erkliğ, Burhan Şahin Abstract: In this article, a unique internal tank and water discharge system are studied for the Sikorsky S-70 model helicopter. CAD design was made, CFD and Static Structural analyses are shown in simulated real-life cases. This alternative design has been proposed to encourage aerial fire extinguishing efforts by using a simpler system at a lower cost and to convert general-purpose helicopters into fire helicopters when necessary. The examination of test methodologies simulating real-life scenarios was conducted using Ansys Fluent and Ansys Static Structural. Research findings indicate that the integration of the new generation water tank within the cabin has resulted in substantial enhancements and has diversified aerial extinguishing capabilities.

Authors:Onur Davuça; Canan Uraz Abstract: In this study, it is aimed to synthesize more environmentally friendly and low-cost biopolymer based super plasticizers (SP) by using biopolymers (starch, chitosan polysaccharide, floral oils, etc.), acrylic acid, maleic anhydride, sodium vinyl sulphonate and various corn starches and various catalysts. These raw materials have been examined in terms of their water holding capacity, viscosity, bond structures and renewability. For the structure determination of the synthesized products, FT-IR, fluidity and compressive strength tests are performed. Because it is aimed also to meet the local consumption of cement materials additives in Turkey. In this process, it is to protect our environment by making it bio-based as much as we can, away from today's chemicals and petroleum derivatives. Three different types of polymer are synthesized: flower oil, bowine gelatine and mpeg5000. The ratio of sand:cement:water in the cement mixture used in the study is 2:1:0.45. Synthesized SP polymers were added to the cement mixture at a rate of 0.75%. In the experiments by connecting a plurality of parameters when selecting the appropriate optimal values according to the appropriate product and polymerizing bond products it was synthesized. FTIR results match the peaks in each raw material. So detailed generalization of the bond structure is appropriate. It can be said that bio raw material synthesis is encouraging in the future, and it can be found that form the compressive strength test, the flower oil being more resistant. As a result of this study, three types of polymeric additives were successfully synthesized and analyzed and performance tests were completed. PubDate: Mon, 10 Jun 2024 00:00:00 +030

The installation of solar power plants has been increasing continuously, as a result of the numerous studies conducted to date. The purpose of this study is to compare various parameters for solar energy and 1 MW photovoltaic solar power plants in the provinces of Gaziantep, Konya and Hatay.Additionally, this study calculates and compares hour angles and azimuth angles for the provinces of Gaziantep, Konya, and Hatay on the 21st of June, which is generally the solstice of the year. This day marks the beginning of summer or winter, representing the time when the sun reaches its highest or lowest point of the year. PubDate: Mon, 10 Jun 2024 00:00:00 +030
