    Abstract: The present invention provides an electrodeposition-coated article production method which is suitable for producing an electrodeposition-coated article comprising a carbon fiber-reinforced plastic. An electrodeposition-coated article production method according to the present invention includes: a molding step of obtaining a carbon fiber-reinforced plastic molded article by curing a prepreg comprising a carbon fiber reinforcement and a thickened product of an epoxy resin composition in which a bisphenol A epoxy resin, [4-(glycidyloxy)phenyl]diglycidylamine and a curing agent component are mixed; and an electrodeposition coating step of coating the carbon fiber-reinforced plastic molded article by electrodeposition. The epoxy resin composition, when cured at 140° C., gives a cured resin which has a glass transition temperature G?-Tg of more than 100° C. and less than 200° C. and in which a dynamic storage elastic modulus G? value at 200° C. is more than or equal to 8% of the value at 100° C.

  • Publication number: 20220290612
    Abstract: What is provided is a fuel supply system that includes a fuel gear pump that is driven by an electric motor and sends fuel in a fuel tank to a fuel nozzle that supplies fuel to the combustor, a controller that controls a rotational speed of the electric motor, and the flow rate measurer that measures the flow rate of fuel discharged from the fuel gear pump. When the difference between the fuel flow rate actually discharged from the electric motor and a target value of the flow rate is equal to or greater than a first threshold value with respect to the target value, the controller adjusts the rotational speed of the electric motor so that the measured value of the flow rate of the fuel discharged from the fuel gear pump approaches the target value.

  • Publication number: 20220290576
    Abstract: An aircraft propulsion system includes: a gas turbine engine attached to an airframe of an aircraft; a generator connected to an engine shaft of the engine; a first electric motor driven using electric power including electric power generated by the generator; a rotor attached to the airframe of the aircraft and driven using a driving force output by the first electric motor; and a control device configured to control an operating state of the engine. The control device includes a flow rate controller which reduces the flow rate of fuel supplied to the engine so that the engine does not misfire when a decrease in output of the engine is promoted using a driving force output by a second electric motor included in the generator, and a drive controller which controls the magnitude of the driving force output by the second electric motor so that the temperature of the engine does not exceed an allowable temperature.

  • Patent number: 11359550
    Abstract: In an aircraft gas turbine engine equipped with a bleed-off valve that bleeds intake air compressed by a compressor exterior and an electric actuator that drives the valve when current is supplied, a required valve opening ?r and a current value Ia corresponding thereto are calculated and Ia is supplied to the actuator to bring valve opening ? to the required opening ?r. Then Ia is compared with a current value Ib and if Ia exceeds 1b, the valve is estimated to have failed and another current value Ic is calculated and Ic is supplied to enlarge valve opening toward wide-opening ?w. Then a current value Id is calculated and supplied to decrease valve opening toward ?r. Next, Id is compared with Ib and the valve is determined normal when Id is equal to or smaller than 1b. If not, it is determined to be faulty.
