Problems solved by technology

[0003] Compared with ARJ21, C919 and other iron bird laboratories, the traditional test method of this type is to conduct a single system test independently through manual manipulation by experienced professional technicians or by using an actuator drive, which has low efficiency and complicated data processing. A fixture can install three-axis drives at the same time to meet multi-axis linkage

Embodiment Construction

[0030] The invention is designed to install the drive device of the three-axis main control system at the same time, realize multi-axis joint adjustment without interference, and can conveniently complete the flight profile test, static calibration test and dynamic test. Safe and reliable, convenient data processing.

[0031] In the cockpit of the aircraft iron bird, remove the seat and the seat slide rail, or remove the seat and use the seat slide rail as the installation reference, install the electric cylinders of each subsystem on the bottom plate through the fixture, and drive it through the servo actuator The rotation of the steering wheel, the forward push and pull of the steering rod, and the reciprocating motion of the pedals, through this tooling, can ensure that the rotating shaft of the steering wheel can not only meet the function of rotation but also the function of moving forward and backward, and at the same time, it is compatible with the reciprocating motion o...

Abstract

The invention provides a method for an aircraft main control system test. The method comprises the following steps: obtaining an operation instruction; sending the operation instruction to an analog driver, wherein the analog driver is installed on an aircraft floor; and performing the corresponding main control system test by the analog driver according to the operation instruction.

Description

technical field [0001] The invention belongs to the field of aircraft control systems, and in particular relates to an experiment method and device for an aircraft main control system. Background technique [0002] The iron bird test is to verify whether the function and performance indicators of the aircraft system meet the design requirements and design specifications. Among them, dynamic tests, flight profile tests, and static calibration tests are important parts of aircraft subsystem tests. Dynamic tests include elevators, ailerons, The frequency response test of the rudder control system, the step response test, and the flight profile test are mainly to check whether the hydraulic source system can normally supply pressure to the elevator, rudder, aileron (spoiler) booster, and flap control in the flight profile. system and landing gear normal retraction system, so that each system can work normally. The static calibration test includes the rudder load calibration test...
