Problems solved by technology

[0002] During the autothrottle ground test, the autothrottle actuator needs to be involved, and the autothrottle actuator needs to be stimulated to work normally. If the plan on the real aircraft is used, the flight control system needs to be put into the test to stimulate it accordingly. The disadvantage is that the scale of the experiment is large and the investment of resources is large.

Abstract

The invention discloses an automatic throttle actuator excitation method for ground tests, and belongs to the field of aircraft design. In an automatic throttle ground test, a simulation device is often used for excitation of an automatic throttle actuator to achieve control simulation, power supply and interface communication necessary to the automatic throttle ground test. According to the invention, an automatic throttle actuator excitation device is used, in accordance with certain steps, for completing proper excitation of the automatic throttle actuator and detection, determination and disposal of fault statuses of the automatic throttle actuator. The automatic throttle actuator excitation method for the ground tests have the beneficial effects of reducing the scale of the tests, shortening the cycle of the tests and verifying the automatic throttle actuator more comprehensively.

Description

technical field [0001] The invention belongs to the field of aircraft design and relates to an excitation method for an automatic throttle actuator suitable for ground tests. Background technique [0002] During the autothrottle ground test, the autothrottle actuator needs to be involved, and the autothrottle actuator needs to be stimulated to work normally. If the plan on the real aircraft is used, the flight control system needs to be put into the test to stimulate it accordingly. The disadvantage is that the scale of the experiment is relatively large and the input of resources is large. Contents of the invention [0003] The purpose of the present invention is to use the excitation device of the automatic throttle actuator to operate according to certain steps to complete the normal excitation of the automatic throttle actuator and the detection, judgment and disposal of the failure state of the automatic throttle actuator. [0004] A technical scheme of an excitation...
