Design And Implementation Of A Flight Simulator Sound Simulation Subsystem

Omestic flight training simulators are usually made aircraft performance simulation subsystem, sound simulation subsystems, visual subsystems, teacher console subsystem, computer and network subsystems, dynamic simulati on subsystems, avionics simulation subsystems, cockpit simulation points Some systems systems, integrated environmental simulation subsystems and auxiliary subsystems and other components, because the hearing is in addition to the most sensitive human visual nerve, so hearing on the role of human cognitive ability can not be ignored. So an important part of the sound subsystem also simulate flight simulator.The main work of this paper is as follows: First Flight Simulator elaborated sound simulation subsystem significance and background, the current situation at home and abroad; secondly investigation of the technology associated with the system, then the system structure and function of the system do detailed design; then, based on the development of a certain type of aircraft flight simulator, the actual flight background sound recorded live, and according to flight speed, flight altitude, engine speed, retractable landing gear and flaps flags and other factors the establishment of a sound file Library(.WAV format), in the Windows environment, with Visual C ++ 6.0 development tools, real-time broadcast programming Direct Sound technology control simulated training environment sounds, for realistic sound effects. The last major function point method using th e black box system modules have been tested and analyzed by the system performance analysis table performance indicators to ensure realization of the system meet the standards required by the user. The system consists of five parts: a sound acquisition mod ule, playing ambient noise module, mixing module, real-time communication module, play an alarm sound module. Sounds may occur by simulating real flight, the formation of immersive sound feeling, help pilots to properly judge hearing by state aircraft in flight.
