Airworthiness appraisal test system and airworthiness appraisal test method for civil aircraft flight control system

Abstract

The invention discloses a civil aircraft flight control system airworthiness appraisal test system and method, and the system comprises a tested piece which represents a civil aircraft flight control system product; the real load simulates corresponding hardware equipment crosslinked with the civil aircraft flight control system through an actual product, and provides real electrical load characteristics for a tested piece; the simulation load simulates the interface and electrical characteristics of the tested piece and the digital crosslinking equipment, and communicates with the tested piece and the data simulation recording equipment; and the data simulation recording equipment inputs the digital excitation to the simulation load, so that the digital excitation is transmitted to the tested piece through the simulation load, and a test result of performing data simulation on the tested piece through the simulation load is acquired and recorded in real time. According to the embodiment of the invention, the problem that a conventional civil aircraft airworthiness appraisal test scheme cannot comprehensively cover various conditions in civil aircraft airworthiness appraisal, so that the airworthiness appraisal test is difficult to directly reflect the operation authenticity of the flight control system under the normal loading condition is solved.

Description

technical field [0001] The invention belongs to the field of flight technology, and in particular relates to an airworthiness appraisal test system and method. Background technique [0002] Modern commercial aircraft use more new technologies to reduce the pilot's control burden and improve flight quality, and the use of fly-by-wire flight control systems is increasingly replacing traditional mechanical control systems. [0003] For the development of new systems and products for civilian use, huge investments are made in qualification and certification. The new systems and products described above need to be certified according to industry standards such as RTCA DO-160 and civil aviation safety regulations, and must undergo rigorous airworthiness qualification testing before they can be considered safe and ready for use. [0004] The airworthiness appraisal of the flight control system of a civil aircraft is a key element to support the obtaining of an airworthiness certif...

Problems solved by technology

The embodiment of the present invention solves the problem of the traditional civil aircraft airworthiness appraisal test scheme. Since it cannot fully cover various situations in the civil aircraft airworthiness appraisal, it is difficult for the airworthiness appraisal test to directly reflect the reality of the operation of the flight control system under normal load conditions. sexual problems
