This study revisits the meaning of energy security by examining the oil market supply and demand conditions of petroleum products and refinery capacity of three Northeast Asian countries(Korea, China, Japan). In 2006, 10.6 million bid of excess demand occurred and is expected to be 15~22 million bid by the year 2030 in this regional oil market. Different oil demand is caused mainly by the different demands for various petroleum products based on each country's economic structures. If the demands are ranked according to their petroleum products, Chinese case shows gasoil > gasoline > fuel oil> LPG > naphtha > Kero/jet and Japanese case shows gasoil > gasoline> naphtha> Kero/jet > fuel oil > LPG, while Korean case shows naphtha> gas oil > fuel oil > LPG > Kero/jet > gasoline, respectively. Total CDU(Crude Distillation Unit) capacity of three northeast asian countries also have been examined in this respect. This study points out the importance of the information on oil demand and supply, on petroleum products and refinery capacities of the three Northeast Asian countries to enhance the security of the oil market in this region.

급증하고 있는 드론(무인항공기) 분야의 기술 개발과 보급이 활발해지는 효과의 반대급부로서 기존의 유인 항공기 운항의 안전이 위협받고 있다. 본 논문에서는 초경량/소형 드론이 비행하도록 지정된 저고도 공역에 대한 현 제도의 문제를 분석하고 드론의 비행 증가에 따른 항공안전을 확보하기 위한 저고도 공역 재설정을 포함한 공역 제도 개선 방안을 제안한다.

지난 호에서는 인류 최초의 무인동력비행에 성공했고 라이트형제보다 먼저 유인동력비행에도 성공할 뻔했던 랭글리 교수의 이야기를 알아보았다. 이번호에서도 역시 최초의 유인 동력비행에 얽힌 이야기를 다루어 보고자 한다.

The purpose of this study was to address a Remote Airborne Control Simulator that could simulate manned-unmanned teaming (MUM-T mission) for fixed wing UAV. With rapid technological development of unmanned aerial vehicle (UAV), the mission capability of UAV has tremendously grown. The role of UAV extends from simple reconnaissance to highly automated wingman. Accordingly, the requirement of UAV ground simulator should be modified as well to meet function requirements for simulating a MUM-T mission. A developed remote airborne control simulator was developed for conducting fixed wing UAV MUM-T operation simulations on the ground. The newest MUM-T examples, usage, and application of the developed remote airborne control simulator for MUM-T simulation are also presented in this study.

The research for production of jet fuel from petroleum displacement resources such as bio-mass, coal, natural gas mainly consists of three sub-research areas; the fisrt step is the pretreatment for producing a synthetic gas, and the next step is the Fischer-Trophsh reaction process for making hydrocarbons. The last is the upgrading technology for the hydrocarbons to fit a jet fuel specification via cracking and isomerization reactions. This talk presents reaserch trends and main technologies for production of jet fuel derived from petroleum displacement resources.

In this study, the ignition delay time of blended aviation fuels was measured and analyzed to confirm the characteristic of ignition delay according to the blending ratio of bio-aviation fuel to petroleum-based aviation fuel. The ignition delay time of bio-aviation fuel(Bio-6308) was shorter than that of petroleum-based aviation fuel(Jet A-1) at all measured temperatures; further, the ignition delay time of the blended aviation fuels shortened as the ratio of Bio-6308 increased. It was confirmed that the aromatic compounds constituting the Jet A-1 affect these results; this was done by comparing the obtained ignition delay time with that of n-heptane/Toluene.
