OFFSET, a detailed ray-tracing computer code, was developed at NASA Lewis Research Center to model the offset solar collector for the space station solar dynamic electric power system. This model traces rays from 50 points on the face of the Sun to 10 points on each of 456 collector facets. The triangular facets are modeled with spherical, parabolic, or toroidal reflective surface contour and surface slope errors. The rays are then traced through the receiver aperture to the walls of the receiver. Images of the collector and of the Sun within the receiver produced by this code provide insight into the collector receiver interface. Flux distribution on the receiver walls, plotted by this code, is improved by a combination of changes to aperture location and receiver tilt angle. Power loss by spillage at the receiver aperture is computed and is consierably reduced by using toroidal facets.
