The potential environmental benefits of hybrid electric regional turboprop aircraft in terms of fuel consumption are investigated. Lithium-air batteries are used as energy source in combination with conventional fuel. A validated design and analysis framework is extended with sizing and analysis modules for hybrid electric propulsion system components. In addition, a modified Bréguet range equation, suitable for hybrid electric aircraft, is introduced. The results quantify the limits in range and performance for this type of aircraft as a function of battery technology level. A typical design for 70 passengers with a design range of 1528 km, based on batteries with a specific energy of 1000 Wh/kg, providing 34% of the shaft power throughout the mission, yields a reduction in emissions by 28%.

“…Şekil 2 ile farklı elektrokimyaya sahip bataryaların, farklı sıcaklık değerinde performansları gösterilmiştir. Bu nedenle batarya tasarımı sırasında, kullanılacak hücrenin elektrokimyasının seçimi önemli bir tasarım girdisidir (Väyrynen ve Salminen, 2012 (Naayagi, 2013). Enerjinin akışının hassas şekilde izlenmesi ve kontrolü, batarya ağırlığı, maliyeti ve hacmi açısından etkinlik sağlar (Meissner ve Richter, 2003).…”

ÖZETUlaşım araçlarının emisyonlarından dolayı çevre üzerindeki etkileri günümüzde çözüm üretimi açısından üzerinde odaklanılan konuların başında gelmektedir. Bu amaçla yenilikçi ve çevreye etkisi daha az olan ulaşım teknolojileri geliştirilmektedir. Havacılık alanında da uçaklarda tahrik sisteminde daha çok elektrik gücü kullanılanımı alternatifi olarak ortaya çıkmıştır. Elektrik enerjisinin özelliğinden dolayı, uçuş boyunca ihtiyaç olduğunda bulunabilmesi için üretiminin yanı sıra depolanması da gereklilik olarak görülmektedir. Elektrik enerjisinin uçaklarda depolanması için bataryalar diğer alternatifler arasından ön plana çıkmaktadır. Bu çalışmada uçaklarda kullanılan bataryanın tasarımı ve boyutlandırılmasına yönelik girdiler incelenerek tasarım formülleri geliştirilmiştir. Elde edilen formüller ile uçak tasarım aşamasında bataryanın ağırlığına yönelik kestirim ve kapasite iterasyonları yapılması mümkün olacaktır.Anahtar Kelimeler: Elektrikli uçak, batarya, batarya boyutlandırılması, ısıl yönetim SIZING OF BATTERIES USED IN AVIATION USING DESIGN PARAMETERS ABSTRACTThe environmental impacts due to the emissions of transport vehicles are at the forefront of research issues today. For this purpose, innovative transportation technologies with less impact on the environment are being developed. In the field of aviation, the use of more electric power in the propulsion system has also emerged as an alternative. Due to the nature of electricity, it is necessary to store it as well as its production so that sufficient electric power would be available when needed during the flight. Batteries are among the alternatives for storing electricity in airplanes. In this study, input parameters were analyzed for designing and dimensioning the battery used in airplanes. The developed formulas will make it possible to estimate and iterate the weight and capacity of the battery that will be used in the aircraft.

Abstract-High performance power conversion equipment is currently gaining an increasing interest for aircraft applications. In particular, isolated bidirectional DC/DC converters are often proposed for modern HVDC aircraft distribution systems. For such reason an evaluation of several isolated DC/DC converter topology is carried out considering the proposed application, interfacing a 270V DC network with a 28V DC network. A trade off evaluation has been carried out for three different topologies and an experimental prototype has been manufactured for the selected conversion architecture. Simulation and experimental results are provided in order to validate the trade off and the design of the proposed converter.
