The Korean launch vehicle (KSLV-II) has used commercial aviation jet fuel, Jet A-1. Fuel specifications were introduced from Jet A-1 specifications. However, specifications and inspection methods of moisture and particulate matters were changed digitally for convenience and accuracy. To control fuel quality, a fuel management system was established to determine suitability by inspecting it at each stage of warehousing, storage, and application. An analysis room was then established at the Naro Space Center. The possibility of fuel mixing was blocked by warehousing inspection. Long-term component changes were then observed by storage inspection. Finally, suitability of the engine test or the launch vehicle test was determined through application inspection. Long-term analysis verified that the space center's fuel oil storage method was appropriate and that the quality management system was able to handle hundreds of engine tests and several flight tests.

The significance of soil environment is gradually increased due to the soil and underwater contamination caused by petroleum leak accidents. It requires a high cost and long period for the purification of soil compared with other environmental matrix such as water and air. For this reason, it has been embroiled in a legal conflict to find the pollution source and charge of cleanup. In this study, we analyzed the physical properties and typical additives of jet fuel to search a method that can distinguish kerosene and jet fuel contamination. In particular, the chemical marker in kerosene was visualized by the developer and the additives in jet fuel, such as antioxidant and metal deactivator were detected by GC-MS. This study could be used to judge petroleum source at soil contaminant accident sites.

두 달 째 지리한 유고 공습이 지속되고 있다. 유고나 걸프전, 그전의 어떤 경우를 보더라도 항공전력은 전쟁에서 빼놓을 수 없는 핵심이 되고 있다. 이번에는 고급 스포츠용품(?) 이었던 비행기가 전쟁의 필수 무기로 등장하기 시작한 제1차 세계대전의 항공전에 대해서 살펴보자.

Accidents due to aircraft fuel defects rank in the top 13 of the 34 accident types described by CAST-ICAO Common Taxonomy Team(CICTT). Aircraft accidents occur because of the inflow of moisture or pollutants depending on the distribution process and storage environment. To confirm the change in physical properties of the aircraft oil stored for a long time, we stored JET A-1 aircraft oil in a metal can to observe the change after six months. We confirmed that the aircraft oil stored for a long time satisfied the quality standards, and the stability of the fuel oil was high. However, in scenarios in which aircraft oil is stored separately on ships, onshore storage facilities, oil fields, etc., owing to the nature of missions, such as in marine police aircraft, the inflow of moisture or pollutants may likely occur due to changes in the internal and external environment. In addition, pollutants can be analyzed using existing tests and distillation properties, but for moisture, domestic and international standards and domestic laws determine the moisture separation ability of aircraft oil through the water separation index, but the moisture content is not analyzed. Therefore, aviation safety must be secured by adding quality control standards for moisture content and performing revisions to uniformize domestic and international standards and laws.
