    Abstract: Apparatuses, systems and methods for forming elongated composite structural members are provided. One disclosed method includes providing a substantially elongated mandrel having an exterior surface exhibiting a desired geometry. A plurality of plies of fiber material preimpregnated with a thermosetting resin are laid up and pressed onto the mandrel, Pressing the plies of material may include passing one or more rollers over the mandrel and over the plurality of plies along a length of the mandrel, The roller or rollers may be at least partially complementary in shape with the mandrel while maintaining the plies of material in a substantially uncured state during the pressing. The method may include sequentially passing a plurality of rollers over the mandrel and the plies of material. The method may also include configuring a first roller to partially complementarily engage the mandrel and configuring another roller to substantially fully complementarily engage the mandrel.

    Abstract: An apparatus for forming elongated composite structural members with a desired cross-sectional geometry as taken transverse to the length of the member. The apparatus may include a base with a substantially elongated mandrel mounted thereon. One or more rollers configured to at least partially complementarily engage the mandrel are configured to roll over and press a plurality of plies of composite material onto the mandrel. The rollers may be configured to form intermediate structures which partially conform to the geometry of the mandrel prior to forming the final structure, which substantially completely conforms to the geometry of the mandrel. The rollers serve to both form and debulk the structure. The present invention enables the formation of elongated structural members from resin-impregnated materials while maintaining the materials in a substantially uncured state. The formed members may then be cocured with a skin or other composite structure.

    Abstract: A dark field projection display includes a light source, a spatial light modulator, and an optical system for directing light from the light source onto the spatial light modulator. The optical system includes a plurality of optical subsystems and a plurality of reflectors. Each of the optical subsystems has an input aperture and is arranged to image light from the light source, the subsystems forming a spatial distribution of source images whose relative positions are different from the relative positions of the input apertures. Each of the optical subsystems further includes a plurality of reflectors disposed at the relative positions of the source images. Each of the reflectors is arranged to reflect light from a respective one of the subsystems onto the spatial light modulator.
