Research And Realization Of The Flight Instrument Display System Of Civilian Helicopter

Civilian helicopter flight instrument display system is the important part of aircraft cockpit instrument display system. It provides lots of rich graphical information of the flight data, including flight attitude, airspeed, altitude, and so on. Pilots accurately and quickly master this flight information could ensure the aircraft flight safety and mission accomplishment.The graphic play an important role in the information output of flight instrument display system. In response to the actual needs of the system, this paper does research about linear generation algorithms, curve generation algorithms and region filling algorithms. And on the basis of the study of these algorithms, some improved algorithms are given and have a better effect through the experiments.The civilian helicopter flight instrument display system frequently use the raster display, so inevitably there will be varying degrees of graphics aliasing. This paper introduces the causes of aliasing and classic anti-aliasing technology. Then give a specific anti-aliasing scheme to ensure the quality of the graphics display.Based on Visual C++6.0 and use the anti-aliasing technology and Windows GDI, This paper complete the design of civilian helicopter flight instrument display system. And then complete the graphic display of flight instruments based on AT89S52, IMU and so on. After system commissioning, these designs have the basic functions of primary flight display of EFIS.
