Patent number: 11359550Abstract: 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.Type: GrantFiled: March 10, 2020Date of Patent: June 14, 2022Assignee: Honda Motor Co., Ltd.Inventor: Akira Ota

Patent number: 11280222Abstract: A method of assembling thin-walled curvilinear components to a bulkhead offers a cost-effective, time-saving process of manufacture. Each component includes a faying edge configured to be aligned with respect to the other. A first component and the bulkhead are preassembled.
