Differences Between Heavy Frame, Industrial Gas Turbine and Aero (Jet) Engine Designs

Hee-Koo Moon(문희구) 한국유체기계학회 2023 한국유체기계학회 학술대회 논문집 Vol.2023 No.12

Design and technology differences between aero and land-based gas turbines are addressed based on the author’s career working for an OEM (original equipment manufacturer) and consulting for other OEM companies (heavy-frame engine company and aero engine company) after retirement. Comparisons of aero-derivative, mid-size industrial & heavy duty gas turbine engines are introduced in perspective of design, technology, and manufacturing in consideration to satisfy objectives of its application. Design configurations are dictated by optimization of design criteria such as power density (power/thrust per weight, efficiency/specific fuel consumption, durability, cost, and size (engine physical envelope). For instances, the operation envelope for aero engines changes from sea level to high altitude (>30,000 ft.) in a single mission while land-based engines typically operate near sea level. The turbine inlet temperature (TIT) of an aero engine is highest during takeoff while the land-based engine has the highest TIT for a full load steady state condition. The modern designs of aero engines and land-based engines were evolved over past 80 years with advancements of technology. Although they share the same fundamentals, the optimization for different applications between aero and land based GTs resulted in significantly different designs, engineering practices, fabrication/manufacturing processes and required database.

문희철(Hee-Cheol Moon),최성월(Xing-Yue Cui),형정(Jing Xing) 한국무역학회 2008 무역학자 전국대회 발표논문집 Vol.2008 No.8

IT기술의 급속한 발전 및 전통적인 무역방식과의 비교에서 국제무역 전자화가 지니고 있는 독특한 문제점과 전문성으로 고려하여 볼 때, 그동안 수행했던 무역정책과 방법으로는 더 이상의 발전을 기대하기는 어려운 것이 사실이다. 뿐만 아니라 전자상거래에서 발생할 수 있는 불완전한 인증 및 결제제도, 소비자 보호, 개인정보의 노출 등과 관련한 문제점들이 많이 발생하고 있는데 이는 전자상거래의 환경에 맞는 법ㆍ제도 등의 정비가 시급하다. 이에 본 논문에서는 국제기구에서 주로 논의되고 있는 이슈화되고 또한 네트워크를 통하여 국가라는 장벽을 뛰어넘어 양국 간의 이용자에게 직접적인 영향을 끼치는 분야에 대하여 비교ㆍ분석하여 중국의 전자상거래 문제점과 활성화 방안을 모색하였으며, 더 나아가 정책적 개선방안을 제시하여 양국 간의 전자상거래 활성화에 기여하고자 연구를 진행하였다. Recently, considering the important role of e-Commerce in the national and worldwide economic development, many countries in world and the international institutions have debated actively over the necessity of support or regulation of e-Commerce. In this context, to find solutions to promote e-Commerce in Korea and China, this thesis investigates the status and characteristics of e-Commerce and compares the e-Commerce policies in two nations. Especially, this study focuses on the improvement of policy measures of Chinese government, which drives various e-Commerce related policies to catch up e-Commerce development of advanced countries including Korea. According to the literature survey and analyses of data from the Internet, e-Commerce development in China is still in the early stage compared to that of Korea and has many significant problems. First, e-Commerce related laws and regulations are not prepared well, and policy making process lags behind technological application. Secondly, settlement or security infrastructure for e-Commerce is not constructed yet. Thirdly, China can not adopt timely global e-Commerce standards and lacks new technology standard. Lastly, excessive government regulation" restrict various information exchanges and free business minds of business circles. To solve these problems inhibiting e-Commerce development in China, first of all, Chinese government needs to adopt appropriate laws and regulations covering various e-Commerce issues including tax and customs, electronic signature and certification, e-Commerce standards, and consumer protection and privacy, etc. Secondly, Chinese government hasten to construct settlement or security infrastructure to support various e-Commerce including B2B, B2C and B2G. Thirdly, active participation in international discussions on e-Commerce development in the international institutions is needed, to reflect realities current situations of China to adopt global e-Commerce standards and to standardize new technology. Lastly, Chinese government should moderate excessive regulation on e-Commerce. In conclusion, to promote e-Commerce between Korea and China, governments of two countries need to cooperate closely in various e-Commerce issues, including tax and customs, electronic signature and certification, e-Commerce standards, and consumer protection and privacy, etc. Finally, this study suggests some cooperative policy measures including information exchanges based on tax treaty, exemption of tariffs on e-Commerce, cooperation in adoption of e-Commerce standards, concluding MOU(memorandum of understanding) on mutual authentication of privacy, interoperability of certification system, cultivation of e-Commerce experts in Korea and China, and activation of Electronic Commerce Promotion Council of Korea and China to discuss on the various e-Commerce issues.

문희철(Hee-Cheol Moon),백은영(Eun-Young Baek) 한국무역학회 2016 무역학자 전국대회 발표논문집 Vol.2016 No.6

본 연구는 한국의 미래 성장 동력 창출에 대한 제안으로 부가가치 무역의 확대를 위한 지식재산권(Intellectual Property Right, 이하 IPR)무역에 대해 집중적으로 살펴보았다. 이를 위해 한국의 지식재산권 교역을 업종별ㆍ연차별 산업재산권(특허권, 상표권, 디자인권 등) 교역 실태를 분석한다. OECD 회원국 27개국과 과 기타 한국과의 교역이 많은 아시아 국가(중국, 인도, 인도네시아, 싱가폴, 베트남) 등 총 32개국의 지식재산권 관련 데이터분석을 통해 한국의 고부가가치 수출에 영향을 미치는 지식재산권 관련 거시변수를 발굴하는 것이 본 연구의 목적이다. 중력모형을 이용한 실증분석 결과, 한국 지식재산권 수출에 영향을 미치는 요인으로 한국의 기술수출, 한국의 IP 수입, 그리고 인구가 많은 국가일수록 한국의 지식재산권 수출은 증가하는 것으로 분석되었다. The purpose of this paper is to focus a discussion on the trade of the Intellectual Property Right(henceforth, IPR) - a higher value-added business -as a part of creating our country’s future growth engine. To do this, our country’s trade on the IPR is classified by industry and year Industrial Property Right(patent rights, trademark rights, design rights etc.), and then its actual condition is analyzed. To analyze the relevant data, those of a total of 32 countries are collected including 27 OECD-member countries and several Asian ones which trade more with Korea such as China, India, Indonesia, Singapore, and Vietnam. Through the data analysis, we intend to investigate the microscopic variables relevant to IPR, which influences on our country’s higher value-added business exports. According to the result of empirical test using a gravity model, the factors having an effect on the Korea IPR export are technology export of Korea and IPR import of 32 Countries. In addition, it is analyzed that Korea’s IPR export tends to significantly increase where a country has more population.
