    摘要： An automatic aircraft powerplant control system includes a throttle servo for adjusting a throttle valve via a throttle control linkage. A throttle control lever provides a user input to the throttle servo, and a throttle controller controls the throttle servo for controlling a throttle valve. A dual-redundant propellor servo drive provides propellor control, and a dual-redundant mixture servo drive controls an air-fuel mixture. A first processor and a second processor are communicatively coupled with the dual-redundant propellor servo drive and the dual-redundant mixture servo drive and with each other to provide dual-redundant propellor and mixture control. The throttle control lever provides a single lever for pilot control of aircraft power, and the throttle control configuration is compatible with an auto-land capability.

    摘要： A throttle device 1 includes a throttle valve 2 which is disposed in an intake passage 101, and includes a first valve body 20 and a first rotatable shaft 21 for rotatably holding the first valve body 20, a bypass valve 3 which is disposed in a bypass passage 8 connected to the intake passage 101 so as to bypass the throttle valve 2, and includes a second valve body 30 and a second rotatable shaft 31 for rotatably holding the second valve body 30, a common motor 4 for applying a driving force to the throttle valve 2 and the bypass valve 3, a first gear 5 configured to be able to transmit or block the driving force of the motor 4 with respect to the first rotatable shaft 21, a second gear 6 configured to receive the driving force of the motor 4 and transmit the driving force to the second rotatable shaft 31, and a sensor 7 for detecting a rotation amount of the second rotatable shaft 31 of the bypass valve 3 or another rotatable shaft rotating in conjunction with the second rotatable shaft 31.

    摘要： In the present invention, a clogging rate is calculated using a first flow rate function when the degree of clogging of the throttle valve is in the reference state and a second flow rate function estimated based on the intake air volume. For each predetermined period, sample points, which are combinations of the second flow rate function and throttle valve position, are obtained, and the learning points are calculated by averaging a plurality of sample points for each predetermined position range. Based on the plurality of learning points, coefficients a to c of the approximate function of the second flow rate function characteristic are calculated by the least-squares method, and the clogging rate is calculated based on the second flow rate function characteristic and the first flow rate function approximated by the approximate function using the coefficients a to c.

    摘要： An automatic aircraft powerplant control system includes a throttle servo for adjusting a throttle valve via a throttle control linkage. A throttle control lever provides a user input to the throttle servo, and a throttle controller controls the throttle servo for controlling a throttle valve. A propeller servo may be provided for adjusting a propeller governor setting of an engine. A propeller control lever provides a user input to the propeller servo, and a propeller controller controls the propeller servo. A full-authority digital engine control (FADEC) controller is used to automatically control mixing of fuel and air via a fuel-air mixture device. The FADEC controller may be used to automatically provide propeller control.

    摘要： A throttle operating device includes a fixing member, a throttle lever, the throttle lever, a magnet which is configured to rotate in response to a rotational operation of the throttle lever, and a detection sensor. A drive source of the vehicle is configured to be controlled based on the rotational operation angle of the throttle lever detected by the detection sensor. A magnetic shielding unit is disposed in the fixing member and configured to cover a periphery of the magnet and the detection sensor to shield magnetism from the outside.
