Problems solved by technology
[0009] A major drawback of the method based on dynamic linking and the method based on executable program calling is that both methods can only realize the interconnection and intercommunication of heterogeneous system co-simulation, and cannot realize real simulation interoperability

Embodiment Construction
[0054] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0055]The invention realizes the HLA conversion of the FORTRAN model through the co-simulation adapter, so that the subject modeling is separated from the federation member modeling. The FORTRAN federation members invoke the standard services provided by the simulation operation support system indirectly by calling the interface functions of the FORTRAN language in the adapter; the callback service interface of the operation support system is also indirectly returned to the FORTRAN federation members after being encapsulated by the adapter.
[0056] Such as figure 1 As shown, the heterogeneous collaborative interoperability method of HLA federation members based on FORTRAN is applied in the multi-disciplinary collaborative simulation of aircraft. HLA / RTI is used as the soft bus, and the aerodynamic and aerothermal simulation models based on FORTRAN a...

The invention belongs to the technical field of system simulation, and particularly discloses an aircraft federation member heterogeneous cooperative interoperation method of a FORTRAN (Formula Translator). The invention aims at packaging professional simulation models into federation members based on the FORTRAN, and performing distributed cooperative simulation. The method comprises the following steps of: calling appointed matched stack management; calling appointed matched object routine naming; uniformly converting object peripheral routine names; matching parameter passing appointment of a simulation model; matching data types; integrating a process-oriented FORTRAN function and an object-oriented VC / C++ function; finishing a callback function of an aircraft simulation model based on the FORTRAN; realizing a cooperative interoperation function module; and realizing heterogeneous cooperative interoperation of HLA (High Level Architecture) federation members based on the FORTRAN. The method has the advantages that the FORTRAN model not only can be called based on a cooperative simulation software bus, but also can call the simulation services which are developed based C / C++ and the like through the cooperative simulation software bus.
Description
technical field [0001] The invention belongs to the technical field of system simulation, and in particular relates to a FORTRAN-based heterogeneous collaborative interoperability method for HLA federation members of an aircraft. Background technique [0002] At present, domestic and foreign aircraft simulation research in the field of aerospace generally involves the interaction of multiple subsystems such as electromechanical hydraulic control and the mutual coupling of multiple disciplines such as materials, control, machinery, aerodynamics, mechanism dynamics, and kinematics. Co-simulation of heterogeneous models is a necessary condition to ensure simulation accuracy and information integrity. Simulation high-level architecture HLA is an internationally common multi-disciplinary collaborative simulation technology framework, and has become an IEEE industry standard. How to be compatible with various heterogeneous subject models within the HLA framework is a problem that ...
