Enerjinin verimli bir şekilde kullanılması, su ve gıda sorunlarından sonra çözümlenmesi gereken en önemli konulardan birisidir. 2020 yılında Türkiye'de yaklaşık 290 milyar kilowatt saat elektrik tüketimi gerçekleşmiştir. Endüstride elektrik tüketiminin yaklaşık olarak %10'u sıkıştırılmış havanın üretimi için kullanılmaktadır. Bu sebeple sıkıştırılmış hava eldesinde kullanılan kompresörlerin performansının arttırılması endüstri ve ülkemiz açısından büyük önem taşımaktadır. Bu çalışmada, son zamanlarda buzdolabı ve klimalarda yaygın olarak kullanılan döngüsel kompresörlerin verimini arttırmaya yönelik çalışmalar konu başlıkları altında derlenmiş ve incelenmiştir. Ayrıca döngüsel kompresörlerin avantaj, dezavantaj ve teknolojik olarak gelişimleri de değerlendirilmiş olup, literatüre katkı sağlanması amaçlanmıştır.
Rotary compressors have some advantages such as lower noise, vibration, lower cost and few parts. For this reason, it is preferred more than its substitutes such as piston, screw and sliding compressors in cooling and air-conditioning systems. In this study, two different designs, rolling piston and revolving vane, were made to increase the performance of the double-stage, rotary compressor with a volume of 22.6 cc. When the test results are examined, it is seen that the rolling piston compressor consumes 1.3 times less power than the electric motor for 2700 rpm and 3 bar pressure, due to the lower inertia forces compared to the revolving vane compressor.
In this study, which will provide a visionary perspective on the design and manufacture of armed unmanned aerial vehicles and their different generations in the future; A concept design of a mini unmanned aerial vehicle suitable for Special Forces and military tactical use was made. The vehicle which is a tactical armed unmanned aerial vehicle (AUAV) with a weapon system capable of shooting at horizontal, vertical and intermediate angles, tracking the target in motion, aiming and firing. The mathematical modeling of the design for the weapon system was created using complex numbers. The mathematical modeling was transferred to the computer calculations programs. The parametric data calculated were verified by simulations made on the computer.
