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 actuating mechanism excitation apparatus for a ground test, and belongs to the field of airplane designing. The apparatus comprises an industrial control computer, a wiring platform and a set of excitation power source. During an automatic throttle ground test process, an automatic throttle actuating mechanism is excited usually by use of a simulation device so as to control simulation, power supply and interface communication which are needed by an automatic throttle ground test. The apparatus is based on a system structure of the industrial control computer, a data collection card and the wiring platform and has the following advantages of shortened test scale, shortened test period, and more comprehensive verification of the automatic throttle actuating mechanism.

Description

technical field [0001] The invention belongs to the field of aircraft design, and relates to an automatic throttle actuator excitation device suitable for ground tests. Background technique [0002] In the process of conducting the autothrottle ground test, the autothrottle actuator is required to participate, and the autothrottle actuator needs to stimulate the environment 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 input resources are large. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to use a simulation device to excite the automatic throttle actuator, so as to realize the control simulation, power supply and interface communication necessary for the ground test of the automatic throttle. [0004] A technical scheme of an automatic throttle actuator excitation device suit...
