Abstract:

THe NASA Ames Digital Image Generation DIG system was purchased from the Link division of Singer Inc. The system provides a simulated out-the-window, visual image for a larg-vertical-motion flight simulator. As originally designed, the DIG can support four visual channels, which represent four aircraft windows with a single pilot eyepoint. The visual system was originally designed to support flight simulations of high altitude, high speed, fixed-wing aircraft. A Helicopter Air Combat HAC simulation required modifications to the DIG real-time software to support two helicopters engaged in low speed, low altitude, air-to-air combat. These modications included a second eyepoint to provide an out-the-window visual image for the secod aircraft pilot, new moving-target occulating algorithms, an algorithm to test for the existence of a clear line of sight between the opposing helicopters, and the addition of moving rotors on the helicopters in the scene. These modifications to the NASA Ames vertical Motion Simulator VMS system allowed two aircraft to ge independently piloted on a single CGI data base.
