An Intelligent Simulation System for Autonomous Formation Flight of Multi-Aircraft

In order to narrow the gap between theoretical research and practical application of multi-aircraft autonomous formation flight,and accelerate the process from design to product realization of navigation and control system,an intelligent simulation system for autonomous formation flight of multi-aircraft is presented.This simulation system uses multi-channel information acquisition equipment,multi-channel constellation simulator and cooperative flight simulation control equipment,the real flight equipment is connected to the closed-loop simulation,which effectively verifies the feasibility of the navigation and control system scheme.In the simulation system,the same clock module is used to control the operation cycle of each channel of the multi-channel constellation simulator and the operation cycle of the dynamic,so as to solve the problem of inconsistent running time of the two systems,effectively reduce the error of the simulation system,and enhance the authenticity of the simulation.Based on expert experience,it can send instructions,judge status and fault diagnosis independently,realize intelligent test and improve simulation efficiency.The application example shows that the simulation results of autonomous formation flight are consistent with the real flight results,which proves the effectiveness of the design scheme of the simulation system.At the same time,the software,hardware and equipment of flight products are developed synchronously based on the system,which shortens the research and development cycle and cost.
