Rüzgâr türbininin kurulacağı yerin rüzgâr potansiyeli, verimli bir elektrik üretimi için oldukça önemlidir. Türbinlerde kullanılan jeneratör tipi, kanat aerodinamiği ve kanat sayısı verimi etkileyen faktörlerdendir. Kanat profili, kanat yapısı ve sürüklenme katsayısının kaldırma katsayısına oranı da (CL/CD) verimlilik bakımından türbin performansını etkileyen önemli parametrelerdir. Farklı kanat profillerinde aynı hücum açısında (CL/CD) oranı farklılık gösterebilmektedir. Bu çalışmada biyomimikri yöntemi ile baykuş kanadı formundan ilham alınarak NACA-4412 profili üzerinde kanal açılmıştır. Kanallar, kanal genişliği 12 mm ve kanal derinliği kanat profilinin yüzeyinin %10 oranında küçültülmesiyle tüm yüzeyde 40 mm mesafe ile 5 tane olacak şekilde oluşturulmuştur. Farklı Reynolds sayılarında ve farklı hücum açılarında analizler gerçekleştirilmiştir. Kanallı model için sürüklenme katsayısı(CD) ve kaldırma katsayısı(CL) değerleri elde edilmiştir. Kanallı ve kanalsız model için analizlerin gerçekleştirildiği hücum açıları ve Reynolds sayılarında kaldırma katsayısı/sürüklenme katsayısı (CL/CD) oranları kıyaslanmıştır. Yapılan analizler sonucunda kanal açılmış kanat profilinin CL/CD oranın daha yüksek olduğu görülmüştür. Referans modelden daha iyi bir performansa sahip olduğu anlaşılmıştır.","PeriodicalId":50152,"journal":{"name":"Journal of Marine Engineering and Technology","volume":"99 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135321795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the field of traffic and transportation, the development of unmanned technologies is remarkable, and it is already moving on to the practical stage in the field of transportation infrastructure such as automobiles, railways and aircrafts. The development of automation and autonomy technologies is expected not only to save manpower and reduce labor, but also to eliminate human errors and greatly contribute to ensuring our safety. This paper focuses on our autonomous technology for ships and also introduces the history of our development processes. In view of the greater use of the autonomous technology in society in the future, this innovation is considered to be also used for inspection work on marine infrastructure such as breakwaters and revetment structures. With this notion in mind, we have conducted an experiment to confirm whether our autonomous vehicles are suitable to meet such a purpose. In addition, we describe the expectations, challenges, and prospects for practical applications of the technology in other areas, such as marine traffic and security, as well as inspection applications for marine infrastructure.","PeriodicalId":50152,"journal":{"name":"Journal of Marine Engineering and Technology","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135637575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the other hand, when automatic navigation is performed in a relatively restricted area, such as a harbor, the target area has a dense environment with many obstacles such as other vessels and buoys, which requires highly accurate route tracking. In addition, the system must navigate a course that can maintain appropriate distances from obstacles in preparation for unexpected external forces such as wind. In this paper, we propose a method to generate an appropriate navigation route to satisfy different requirements of two chart types, namely charts for automatic navigation in offshore areas that are defined as sparse wide-area maps and those for automatic berthing and unberthing that are defined as dense narrow-area maps. The proposed method was then applied to the actual environment to verify its usefulness, and then automatic navigation was performed using a generated route.","PeriodicalId":50152,"journal":{"name":"Journal of Marine Engineering and Technology","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135637586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
