Aircraft simulation system of flight simulator

Abstract

The invention provides an aircraft simulation system of a flight simulator. The aircraft simulation system is composed of a simulation platform and a piece of simulation software. The simulation platform is composed of a host computer and a target computer. The host computer provides a Windows Xp environment, and selects a Tornado 2.2 real-time development environment. The simulation platform adopts an embedded multi-task operating system VxWorks 5.5 as the operating system on which the aircraft simulation software relies for running. The simulation software is aircraft simulation software developed through C language and C++ mixed programming and adopts a modular structure and a multi-task and single-rate simulation mode, and the simulation cycle is 10 milliseconds. Software modules include a real-time management module, a flight performance simulation module, an aircraft system simulation module, a weapon simulation module and a network management module. The operating system of thesimulation system occupies fewer system resources and runs stably. The design and implementation of a software model are fast, and the reliability is high. The requirements of flight training and program training of pilots in full envelope can be satisfied.

Description

technical field [0001] The invention relates to the technical field of computer simulation, in particular to a flight simulator aircraft simulation system. Background technique [0002] At present, flight simulators are widely used in the field of flight training. Compared with actual flight training with real aircraft, flight simulator has the advantages of controllability, non-destructiveness, economy, reliability and so on. [0003] The aircraft simulation system is the core component of the flight simulator. It is used to simulate the flight performance, handling quality, functions and working states of the aircraft, and is integrated with the cockpit simulation system, instructor console system, visual system, avionics simulation system and sound Simulation system, etc. for data interaction. Therefore, it is very important to design an aircraft simulation system with high fidelity, strong real-time performance, stable performance and can adapt to multiple models. The ...
