Publication number: 20190308751Abstract: An aircraft management system includes a sensor, a diagnosis executor, and an outputter. The sensor is loaded onto an aircraft. The diagnosis executor diagnoses health of a part of the aircraft on the basis of output from the sensor while the aircraft is flying. The outputter outputs predetermined recommendation information to an outside of the aircraft through wireless communication, in the case where the part satisfies a preset maintenance recommendation condition as a result of the diagnosis of the health.Type: ApplicationFiled: April 3, 2019Publication date: October 10, 2019Applicant: SUBARU CORPORATIONInventor: Hideki SOEJIMA

Publication number: 20190265126Abstract: A diagnosis apparatus includes a fiber optic sensor, a collection processor, and a self-diagnosis processor. The fiber optic sensor is configured to be disposed over a target. The collection processor is configured to perform a collection process that collects measurement data related to the target obtained by the fiber optic sensor. The self-diagnosis processor is configured to perform a self-diagnosis process before the collection processor starts the collection process. The self-diagnosis process obtains an output value related to calibration of the fiber optic sensor, causes the collection processor to start the collection process when the output value falls within a proper range, and outputs an error when the output value falls outside the proper range.Type: ApplicationFiled: December 20, 2018Publication date: August 29, 2019Applicant: SUBARU CORPORATIONInventor: Hideki SOEJIMA

Publication number: 20190112072Abstract: According to one implementation, a damage detection system includes: a physical quantity detection unit, a flight condition changing part and a damage detection part. The physical quantity detection unit detects a physical quantity of a structural object composing an aircraft during a flight of the aircraft. The flight condition changing part changes at least one flight condition of the aircraft to at least one specific flight condition when the physical quantity of the structural object has been detected by the physical quantity detection unit. The damage detection part determines whether a damage arose in the structural object, based on a physical quantity which has been detected, from the structural object of the aircraft flying with the at least one specific flight condition, by the physical quantity detection unit.Type: ApplicationFiled: December 12, 2018Publication date: April 18, 2019Inventors: Masakatsu ABE, Hideki SOEJIMA, Takeshi FUKUROSE

Patent number: 10054568Abstract: The object of the invention is to provide a damage diagnostic system that uses a damage detection system that obtains propagation intensity distribution data, which is expanded in the two dimensions frequency and propagation time, by converting the output value from an oscillation detection sensor that was obtained when oscillation is performed by an oscillator, and for one mode or two or more modes that are selected from the fundamental mode and higher mode of Lamb waves, obtains certain characteristic values from the data, for example three indices, which are the slope of the mode dispersion of the A1 mode (rate of change of the propagation time with respect to the frequency), the amount of decrease in the propagation time of the A1 mode, and the amount of increase in the propagation time of the S0 and S1 modes, and outputs the measurement results. The measurement results are displayed on a display device.Type: GrantFiled: July 18, 2014Date of Patent: August 21, 2018Assignees: SUBARU CORPORATION, THE UNIVERSITY OF TOKYOInventors: Hideki Soejima, Yoji Okabe

Patent number: 9726645Abstract: A vibration detection apparatus includes a ring laser resonator, a fiber Bragg grating and a detection system. The ring laser resonator generates a laser beam propagating a ring shaped optical path. The fiber Bragg grating is disposed in the ring laser resonator such that the laser beam enters the grating, and has a transmittance distribution characteristic of transmitted light in a wavelength direction, which changes in accordance with vibration of an object. The detection system detects the vibration based on the transmitted light through the fiber Bragg grating.Type: GrantFiled: February 9, 2015Date of Patent: August 8, 2017Assignees: SUBARU CORPORATION, UNIVERSITY OF TOKYOInventors: Hideki Soejima, Yoji Okabe, Qi Wu
