Design And Implementation Of A Small Aircraft Flight Simulator For Primary Training Plane

With the rapid development of computer simulation technology,its research and application has attracted more and more attention from countries in the world,Flight simulator is a typical loop with some hardware simulation system,it is a typical application of simulation technology in the field of national defense,it plays an increasingly important role in pilot's flight and command technology teaching and training.The application of flight simulator has been developed from stand-alone training to multi-machine training,that is,multiple users could do interactive training in the same environment in multiple simulators by using network.The development team developed a small,low cost,easy equipped and high fidelity network flavor flight simulator for primary trainer.In development process,We highlighted the single-person single-program training and network multi-person interactive training in function design.On the one hand,the simulator can be used as a full mission flight simulator to implement flight subject simulation training according to flight outline;on the other hand it can be used as a flight simulation organization and training client to set up flight command and training comprehensive simulation System,flight command training organization,flight technology teaching multi-dimensional guidance and multi-machine network iterative training could be implemented in it.In this paper,the overall design scheme and the key technology of this simulator were introduced in detail,for example,constructing flight dynamics model by means of coefficient construction and JSBSim,using OSGEarth to realize 3d scene,using Direct Sound to realize 3d sound effect,using network transmission technology and a variety of other techniques to realize comprehensive simulated flight command.The simulator came into use in the 70 anniversary parade task,after upgrading it can further meet the demand of flight simulation training and teaching,a large number were allotted to the flight training base as a small full mission flight simulator and simulation organization command training equipment.Through the usage feedback and flight data comparison,the real-time following of that flight simulation system is very good.With accurate data and high degree simulation,it has a very good effect in flight simulation training.
