Patent number: 10583934Abstract: To provide a fuel pipe of an aircraft that makes it possible to maintain temperature of fuel in the fuel pipe at appropriate temperature while giving consideration to reliability that is constantly required for the aircraft. A fuel pipe provided in an airframe of the aircraft includes: an inner pipe defining a flow path through which fuel flows; and an outer pipe surrounding an outer periphery of the inner pipe. A gap is provided between the outer periphery of the inner pipe and an inner periphery of the outer pipe. The inner pipe is made of a rubber material, and the outer pipe is made of a metal material.Type: GrantFiled: February 22, 2017Date of Patent: March 10, 2020Assignee: MITSUBISHI AIRCRAFT CORPORATIONInventors: Nobuhide Hara, Ushio Komoda

Patent number: 10293195Abstract: There is provided a safety device for aircraft, that prevents an explosion of a fuel tank storing aviation fuel, the safety device including: a flame arrester that is arranged near an end of a ventilation passage on an aircraft outer side, as a part of the ventilation passage allowing the inside of the fuel tank and an outside of the aircraft to communicate with each other, to prevent a flame propagation into the fuel tank from the outside of the aircraft through the ventilation passage; and a heat transfer reducing part that is arranged closer to the outside of the aircraft than the flame arrester to prevent heat transfer to the fuel in the fuel tank from the flame.Type: GrantFiled: February 11, 2016Date of Patent: May 21, 2019Assignee: MITSUBISHI AIRCRAFT CORPORATIONInventors: Yuta Takahashi, Shingo Kawano, Tsutomu Kawamizu, Atsushi Fujii, Shimpei Todaka, Ushio Komoda, Toshiyuki Umemoto

Patent number: 9957059Abstract: A fuel tank that stores fuel to be fed to a fuel supply destination through a pipe, wherein a whole or a portion of a storage fuel contact portion in contact with the fuel within the fuel tank is subjected to surface finishing for imparting hydrophilicity.Type: GrantFiled: February 17, 2015Date of Patent: May 1, 2018Assignee: MITSUBISHI AIRCRAFT CORPORATIONInventors: Shingo Kawano, Atsushi Fujii, Yuichi Kanemaki, Ushio Komoda, Toshiyuki Umemoto

Patent number: 9926082Abstract: An opening portion of a vent member is prevented from being blocked, and thus ventilation is reliably performed. A plurality of opening portions (40A, 40B) are formed in a single vent stringer (20), and thus even in a case where one of the opening portions (40A, 40B) is blocked, ventilation is secured by the other opening portion. At this time, since the opening portions (40A, 40B) are formed in surfaces different from each other in the vent stringer (20), a possibility that both the opening portions (40A, 40B) may be simultaneously blocked is less.Type: GrantFiled: November 27, 2012Date of Patent: March 27, 2018Assignee: MITSUBISHI AIRCRAFT CORPORATIONInventors: Ushio Komoda, Hideto Motohashi

Patent number: 9764851Abstract: Provided is a fuel system that can reduce the amount of fuel in a second tank before the amount of fuel in a first tank. A fuel system includes: a first tank and a second tank that respectively store fuel; a fuel supply pump that supplies at least the fuel in the first tank out of the first and second tanks to a fuel consuming section; a transfer pump that transfers the fuel in the second tank into the first tank; and a fuel passage having an inlet in communication with an inner portion of the first tank, and an outlet in communication with an inner portion of the second tank. The fuel in the first tank overflows into the second tank through the fuel passage.Type: GrantFiled: July 30, 2014Date of Patent: September 19, 2017Assignee: MITSUBISHI AIRCRAFT CORPORATIONInventor: Ushio Komoda

Patent number: 9751633Abstract: The present invention provides an aircraft safety device which can reliably prevent explosion of a fuel tank even if an inflammable gas is ignited. A safety device for explosion-proofing a fuel tank which stores fuel of an aircraft includes: a flame propagation blocking part which blocks propagation of a flame from the outside to the inside of the fuel tank through a ventilation passage which allows ventilation between the inside and the outside of the fuel tank; and a gas supply suppressing part which, when heated by the heat of the flame, suppresses supply of an inflammable gas containing the fuel gas to the flame through the ventilation passage.Type: GrantFiled: February 4, 2015Date of Patent: September 5, 2017Assignee: MITSUBISHI AIRCRAFT CORPORATIONInventors: Yuta Takahashi, Tsuyoshi Kitamura, Tsutomu Kawamizu, Shingo Kawano, Ushio Komoda

Patent number: 9254923Abstract: The present invention ensures explosion-proof performance without increasing the capacity for supplying nitrogen-enriched air in an aircraft fuel system having a ventilation function. An aircraft fuel system includes: fuel tanks; an NEA supply system; a left ventilation channel extending from a ventilation duct to a fuselage and leading into the tanks; and a right ventilation channel extending from a ventilation duct to the fuselage and leading into the tanks. The tank leading to the channel and the tank leading to the channel are separated by a central wall. The tanks communicate with each other through a fuel path, which allows, of fuel and gas, only the fuel to pass through, and float valves.Type: GrantFiled: July 30, 2014Date of Patent: February 9, 2016Assignee: MITSUBISHI AIRCRAFT CORPORATIONInventors: Junichiro Hashimoto, Ushio Komoda
