Abstract

The invention relates to a method for dispatching distributed simulation models in an aircraft simulation system and belongs to the technical field of aircraft system design. The dispatching method is based on a data flow dispatching idea, simulation progress is driven through a data flow, the simulation begins when the data flow is generated, and the simulation is finished when the data flow is terminated. The method for dispatching the distributed simulation models of the aircraft simulation system is achieved by formulating a data interaction protocol between the simulation models and a distributed simulation platform and designing a simulation model execution sequence algorithm. By means of the method, the concurrent design simulation of an aircraft can be achieved, the design efficiency of the aircraft is effectively improved, accurate transferring of simulation data is ensured, and correct execution of a simulation task is further guaranteed.

Description

technical field [0001] The invention relates to a distributed simulation model scheduling method in an aircraft simulation system, belonging to the technical field of aircraft system design. technical background [0002] Aircraft design is a complex system engineering involving multiple disciplines such as aerodynamics, structure, power, control, materials, stealth, electronics, etc. In order to reduce research and development costs, a large number of system simulations are required in the design process. For such a complex project, how to speed up the simulation speed and improve the simulation efficiency is a problem that must be solved to improve the efficiency of aircraft design.
