Abstract:
The US Army Human Engineering Laboratory HEL has developed a computer program for computing the internal cockpit reflections on the transparent canopy surfaces of external point light sources. Computations have been completed for the Model YAH-64 Advanced Attack Helicopter low glare canopy design. The results show that primary reflections as seen from the pilots position are possible on 1 the upper rear corners of the forward side canopy surfaces, 2 the upper edges of the rear sides, and 3 the sides of the top surface. Computations have also been completed for the copilots position and show possible reflections on the front and side surfaces. A computer graphics output is used to show reflection points on canopy layouts and perspectives of the cockpit.
