摘要： A method for fabricating a perforated high temperature fiber reinforced polymer composite material which includes partially curing a polymer composite material to a viscoelastic state without inducing complete cure. The polymer composite material is formable when further heated, but does not experience excessive resin flow during final curing. According to the methods of the present invention, the polymer composite material may be perforated in the partially cured state, or prior to the partially cured state. A rigid pin mat apparatus of the present invention may advantageously be utilized to perforate the composite material. After the partial curing, the polymer composite material may be contoured utilizing a flexible mat pin apparatus of the present invention, or may be contoured utilizing forming tools generally known to the art. The method may advantageously be utilized with fiber-reinforced polymer composite starting materials, such as graphite/bismaleimide preimpregnated fabric, to produce perforated and contoured high temperature fiber reinforced polymer composite materials for sound suppression applications.

摘要： This invention relates to a new ceramic electrostrictive compositions having superior electrical properties, a process for the preparation of the new electrostrictive compositions and applications for the new compositions. Specifically, a solid solution composition of lead magnesium niobate - lead titanate - (barium titanate or strontium titanate) has exhibited desirable electrostrictive properties. This composition shows a diminished dependence of dielectric constant on temperature.

摘要： In a method for fabricating a printed circuit board on a doubly contoured or hemispherical substrate such as a radome, a coherent light source is used to form a plurality of elements of a predetermined pattern on the surface of the substrate. The coherent light source preferably includes an excimer laser. The substrate includes a bottom layer and a metallized layer which is covered by a photoresist coating. The first element of the pattern is formed by directly imaging the element in the photoresist coating. The substrate is then displaced relative to the coherent light source until all the elements of the predetermined pattern are formed in the photoresist coating over the entire surface of the substrate. After the pattern is complete and the photoresist is developed, an etching technique is used to remove portions of the metallized layer from the substrate.

摘要： In a method for fabricating a reusable conformal photomask for a doubly contoured hemispherical substrate such as a radome or a three-dimensional printed circuit board, a light blocking material is deposited on a shell or tool corresponding to the shape of the radome or printed circuit board. A pattern is then formed in the light blocking material, and portions of the light blocking material corresponding to the pattern are removed. The resulting pattern corresponds to the pattern to be formed on the three-dimensional printed circuit board or radome. A light transmissive layer is then deposited over the light blocking layer for support. The light blocking material and the light transmissive material comprise the reusable conformal photomask which is then removed from the shell. The reusable conformal photomask can be used to form an image of the desired pattern on the three-dimensional printed circuit board or radome.

摘要： A nut plate (12) and nut (14) are disclosed wherein the nut plate secures the nut to a mounting plate. The nut plate includes a projection (30) which is adapted to be received by a hole in the mounting plate (32) to prevent relative rotation between the nut plate and the mounting plate. The nut is provided with a flange (26) about a periphery of the nut with a portion of the nut being received within a tubular portion (17) of the nut plate and within an opening in the mounting plate.

摘要： A transmission line comprising a multi-layer dielectric slab structure including: a dielectric substrate layer (30) having a thickness ds and permittivity epsilons; a conductive ground plane (31) on the bottom surface of the dielectric substrate layer (30); a dielectric guiding layer (32) having a thickness h and permittivity epsilong, where epsilong > epsilons, attached to the top surface of dielectric substrate layer (30); at least one elongated and relatively narrow dielectric loading strip layer (33) having a width W, thickness dl, and permittivity epsilonl, where epsilong > epsilonl, attached to the top surface of the dielectric guiding layer (32); and a conductive coating (34) on the top surface of the dielectric loading strip layer (32). Such a structure permits single mode propagation over a relatively wide band. Radiation losses due to coupling of the desired mode to the substrate modes and the conductors are furthermore reduced and the polarization of the dominant mode is such as to render said structure relatively insensitive to small deviations from parallelism among the different interfaces.

摘要： A stabilized platform having five degrees of freedom utilizes a platform supported on a base by a spherical bearing which permits movement about roll, pitch and yaw axes. A triaxis torquer has a non-magnetic stator depending from the platform, permanent magnet rotors disposed on the base which produce a magnetic field through the stator, and a set of electrical windings attached to the stator. Energizing the windings selectively produces torque in roll, pitch and yaw. A mirror gimbal and drive system on the platform provides movement in elevation of a mirror. A motor is provided for rotating the base in azimuth relative to its mounting in a vehicle or the like. A set of rate gyroscopes mounted on the platform and a set of resolvers provide rate of movement of the platform and gimbal, and position information to a servo system which controls the torquers and drive systems to stabilize the platform in roll, pitch and yaw, and to position the mirror in elevation and azimuth. Laser and infrared optical devices may be mounted on the platform and coupled by the mirror to a desired line of sight.
