Publication number: 20240126939Abstract: There are provided a method for designing a mechanical apparatus and a device using the same. A method for acquiring shape information of a mechanical apparatus based on target performance information according to an embodiment may include: acquiring a first target performance parameter and a second target performance parameter of the mechanical apparatus; acquiring first shape information by using a first model based on the first target performance parameter and the second target performance parameter; acquiring a first prediction performance parameter by using a second model based on the first shape information; and updating the first model based on at least one of the first target performance parameter, the second target performance parameter or the first prediction performance parameter.Type: ApplicationFiled: April 13, 2023Publication date: April 18, 2024Inventors: JEONG GYU BAK, SEAWOOK LEE, MUN JIN CHO

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
