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] like 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 are ...

The invention belongs to the technical field of system simulation, in particular to a FORTRAN aircraft federation member heterogeneous collaborative interoperability method. The purpose is to package the simulation professional model into a federation member based on FORTRAN, and carry out distributed collaborative simulation. Including: stack management with matching calling conventions; naming of target routines matching calling conventions; unified conversion of target external routine names; parameter transfer calling conventions matching simulation models; matching data types; integrating process-oriented FORTRAN functions and object-oriented VC / C++ function; complete the callback function of the aircraft simulation model based on FORTRAN; realize the cooperative interoperability function module; realize the heterogeneous cooperative interoperability of HLA federation members based on FORTRAN. The advantage is that the FORTRAN model can not only be invoked based on the co-simulation soft bus, but also the simulation service developed based on C / C++ can be called through the co-simulation soft 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 ...
