Embodiment

[0089] The structural professional model includes: executable file str.exe, input file str_in.xml, output file str_out.xml.

[0090] The thermal protection professional model includes: executable file tp.exe, input file tp_in.xml, output file tp_out.xml.

[0091] Among them, the executable file in the structural professional model is an algorithm file to determine the structural size according to the parameters such as structural heat and thermal deformation; the executable file in the thermal protection professional model is to perform thermal protection according to the input parameters such as structural size and material properties. Design the file to obtain the results related to thermal protection; the input file stores the input parameters required for the execution of the executable file, and the output file stores the execution result of the executable file.

[0092] The parameters passed from the structural major to the thermal protection major (forward transfer) inc...

Abstract

Disclosed is an aircraft system analysis system and method. The aircraft system analysis system comprises a model import module, a parameter mapping module, a system coupling loop identifying module, a loop operation module and a system output module. The model import module imports domain models having the coupling relation into the aircraft system to be marked with domain A and domain B, arrays A.out [am] and B.out [bm] are valuated with response parameters of the domain A and the domain B, arrays A.in [an] and B.in [bn] are valuated with self-variable parameters, and the arrays are stored as XML formatted files. The parameter mapping module maps the parameters between the domain A and the domain B to form coupling files. The system coupling loop identifying module identifies the coupling files to form a coupling loop G0. The loop operation module processes the G0 to obtain a process G1 and operates the G1 until the G0 is balanced, the values of nodes of the balanced forward arrays are stored into AtoB [m], and the values of nodes of the reverse arrays are stored into BtoA [n]. The system output module extracts the values of the AtoB [m] and the BtoA [n], and the values are stored as the XML files of the forward nodes and the reverse nodes and outputted.

Description

technical field [0001] The invention relates to an aircraft system analysis method and system based on a coupling relationship, and belongs to the field of aircraft overall scheme design and optimization. Background technique [0002] The overall plan of the aircraft involves multiple disciplines such as ballistics, aerodynamics, power, control, structure, thermal protection, etc., and there is mutual influence between the specialties, that is, the coupling relationship. The optimal design of a certain specialty cannot bring about the optimal overall plan of the aircraft. Coordination of multiple disciplines is required. The most typical coupling relationship is between the structure and thermal protection disciplines, that is, the structural disciplines transmit attribute information such as structural dimensions and materials to the thermal protection disciplines, and the thermal protection disciplines rely on the parameter information transmitted by the structural discipl...
