Abstract
This paper describes the integration and proposed flight test of the Simulation Program for Improved Rotorcraft Integration Technology (SPIRIT) II helmet-mounted display on the National Research Council of Canada Bell 205 Airborne Simulator. The helmet-mounted display is a wide field-of-view (80 degrees H X 41 degrees V with a 30 degree binocular overlap) high resolution display (1280 X 960 pixels in each eye). Colors are displayed using a field sequential process, whereby green and red laser light is pulsed and directed onto the surface of a reflective ferro-electric liquid crystal display. The prototype helmet-mounted display overlays red, amber, or green symbology on monochrome green imagery obtained from high resolution daylight cameras. The optical design of the display does not form an exit pupil. This allows the wearer greater freedom in movement and comfort due to looser helmet fit tolerances. The helmet-mounted display was integrated with a head tracker and camera platform to form a visually coupled system on the National Research Council of Canada Bell 205. The integration process and flight test plan will be discussed.
