Embodiment Construction

[0011] Below the present invention is described in further detail, see figure 1 , realizing this method mainly includes components such as throttle console assembly, engine controller assembly and propeller controller assembly, and throttle console assembly includes throttle lever 1 and the angle sensor 2 that is installed on the throttle lever, and controller assembly includes engine 3, engine electronics Controller 3a and bus 3C, the propeller controller assembly includes propeller 4 and propeller electronic controller. Engine electronic controller 3a is installed on engine 3, controls engine power. The propeller electronic controller 4a is installed on the propeller 4 to control the propeller speed and blade angle. It is characterized by:

[0012] (1) Push and pull the throttle lever 1 back and forth, drive the angle sensor 2, and the angle sensor 2 is collected by the engine electronic controller 3a. The angle of the throttle stick represents the pulling force required ...

Abstract

The invention belongs to the technology of civil airplane engine operation system design and relates to a structure for using a single throttle lever for comprehensively controlling an engine and a propeller of a civil turbo-propeller airplane. The method is characterized in that one throttle lever is used for comprehensively controlling the power of the engine and the propeller; the angle of the throttle lever is transmitted to an electronic controller of the engine through an angle sensor; according to the angle of the throttle lever and a preset control law, a power instruction of the engine and a control instruction of the propeller are determined; the electronic controller of the engine controls the oil supply amount according to the power control instruction of the engine; the control instruction of the propeller is transmitted to an electronic controller of the propeller through a bus; and the electronic controller of the propeller determines a control law, the rotation speed and the propeller blade angle of the propeller according to the instruction. By the adoption of the method, throttle operation of a traditional turbo-propeller airplane is effectively simplified, the engine and the propeller are comprehensively controlled through the single throttle lever, throttle control and operation are simplified, and the flight safety is improved.

Description

technical field [0001] The invention belongs to the design technology of an engine control system of a civil aircraft, and relates to a method for comprehensively controlling an engine and a propeller of a civil turboprop by using a throttle lever. Background technique [0002] In traditional civil turboprop aircraft, two control levers are usually designed on the central console of the cockpit for the control of a single engine and propeller: the power lever and the status lever, the power lever controls the engine power, the status lever controls the propeller, and the two levers Cooperate with the control to realize the comprehensive control of the engine propeller and generate the target pulling force required by the aircraft. This kind of design interface is relatively complicated, and the pilot needs to manually realize the coordination of the manipulation of the two levers during manipulation, which is not conducive to flight manipulation. After realizing the compreh...
