Patent number: 10099794Abstract: A vertical take-off and landing aircraft using a hybrid electric propulsion system includes an engine, a generator that produces electric power using power supplied by the engine, and a battery that stores the produced electric power. A motor receives the electric power stored in the battery and electric power produced by the generator but not stored in the battery and provides the power to a thrust generating apparatus. A controller selects either silence mode or normal mode, and determines the amount of electric power stored in the battery and the amount of electric power not stored in the battery from the electric power supplied to the motor. In the silence mode, the controller supplies only the electric power stored in the battery and controls a duration by adjusting output power of motor. In the normal mode, the controller supplies electric power not stored in the battery.Type: GrantFiled: February 15, 2018Date of Patent: October 16, 2018Assignee: HANKUK CARBON CO., LTD.Inventors: Jeong-Gyu Bak, Jinsoo Cho, Boseong Kim, Senghyun Yun, Sunghong Won, Tae-Chul Jeong, Sooyoung Cho, Geunho Lee, Kyusung Park, Juhyung Ha, Changmo Moon, Sunho Beck, Changjun Meang, Hanki Lee, Minjun Kim, Dain Lee

Patent number: 9915014Abstract: A flexible second gas barrier for a liquefied gas storage tank which includes a stiffener fabric weaved with two or more kinds of fiber yarn selected from a group consisting of a glass fiber, a carbon fiber, an aramid fiber, and a synthetic fiber. The stiffener fabric is weaved so that a hybrid fiber yarn is made by 2-ply yarning two or more kinds of a single yarn or a twisted yarn of fiber yarn selected from a group consisting of a glass fiber, a carbon fiber, an aramid fiber, or a synthetic fiber, is included in the weft and/or warf so that repeated fatigue resistance, even under cryogenic conditions, is achieved, which ultimately has the effect of solving the problems associated with repeated load increase imposed on the second gas barrier as the thickness of LNGC Foam increases.Type: GrantFiled: June 28, 2016Date of Patent: March 13, 2018Assignee: Hankuk Carbon Co., Ltd.Inventors: Jeong Cheol Kim, Min Gyu Kim, Kyung Han Kim, Ju Hwan Hong
