摘要： An underwater acoustic projector including a Class IV flextension shell, preferably in the form of an ellipsoid, is connected to and driven by two substantially identical electromagnets having mutually opposing pole faces and having a common spatially uniform air gap which is centered between the pole faces. The coils of the two electromagnets are connected in series and when excited by a controlled current, generate a mutually attractive variable reluctance force which causes the pole faces to be attracted toward one another. The shell secured to the electromagnets elastically flexes along one of two mutually perpendicular axes resulting in a volumetric displacement of the outer surface of the shell.

摘要： A variable reluctance acoustic projector includes a piston structure that provides rigid retention and precise alignment of electromagnetic cores within the projector housing. The piston structure provides a pair of metallic piston blocks having cavities in which the electromagnetic cores are mounted. The piston blocks rigidly retain the electromagnetic cores within the cavities by compressive loading, improving the structural reliability of the device. In addition, the piston blocks enable precise alignment and orientation of the pole faces of opposing electromagnetic cores parallel to one another. Flexure ribs formed in the piston blocks increase the compliance of the blocks to substantially confine motion of the piston blocks to translation along a single axis of actuation during excitation of the electromagnetic cores.

摘要： A structural support for cryogenic apparatus used in a vacuum vessel includes a plurality of spaced parallel plate members having honeycomb structures interposed therebetween and joined to the plate members. The honeycomb structure provides for a plurality of cells which are the same pressure existing within the vacuum vessel by reason of apertures being provided in the plate members or cell structures. The apertures are arranged so that they are offset from plate-to-plate or cell-to-cell in order that there be no direct optical path from the top of the support structure to the bottom or from side-to-side.

摘要： An electrical switch for switching direct current in an inductively driven electromagnetic projectile launching system is provided with a rotor having a generally cylindrical conductive element with a first portion that includes a continuously conductive external surface. A second portion of the conductive element includes a pair of insulating members fixed at angularly spaced locations such that sections of the conductive elements and the insulating members alternate along the generally cylindrical surface of the elememt. One pair of angularly spaced retractable brush members extend radially inward toward and axially along the conductive surface of the first portion of the conductive element to make sliding electrical contact with the conductive element during the inductor charging phase of a launch sequence. A second pair of angularly spaced retractable brush members extend radially toward the segmented portion of the rotor conductive element and serve to commutate current from the switch to a pair of generally parallel projectile launching rails. A switch housing encircles the rotor and supports conductors which are used to electrically connect one brush of each pair to the launcher circuit. The other brushes are electrically shorted. Means is provided for moving the brush members into and out of contact with the rotor conductive element to achieve the desired switching function.

摘要： An inductor with high inductance to resistance ratio capable of handling megamp currents. Sixteen coil assemblies are radially arranged into four quadrants of four coil assemblies each and jumpers are utilized to connect the quadrants in different configurations for different inductance values. Each coil assembly is made up of a plurality of nested essentially D-shaped copper conductors collectively nested within an aluminum structural support plate in which eddy currents are minimized by a interruption in the plate. The individual conductors of each coil assembly are transposed throughout a quadrant for balanced current flow. Coil bus bars as well as an input and output bus bar are connected to predetermined ones of the coil assemblies with the input and output bus bars being connected to system input and output leads. The unit is operated at cryogenic temperatures by immersion in a liquid nitrogen filled cryostat.

摘要： A superconducting magnetic energy (SMES) system having an axially sectioned multilayered solenoid coil immersed in a liquid helium bath contained in annular helium vessel includes as an interface between each section of the inner and outer layers of the coil and the helium vessel a finger plate assembly comprising a plurality of electrically nonconductive finger plates clamped at one end with spacers between adjacent finger plates to hanger plates welded to the helium vessel walls. The other ends of the finger plates are interleafed with the turns of the coil and clamped together with the coil turns by clamping assemblies which clamp the turns in adjacent layers of the coil. Loading bars between the layers transmit the radial loads generated by the magnetic and thermal forces acting on the coil to the finger plates. The radial loads pass through the finger plates to the helium vessel side walls and then through radial struts outside the helium vessel to the walls of a trench in which the SMES system is installed. Axial loads on the coil produced by the Lorentz force and differential thermal expansion and contraction of the coil relative to the helium vessel are absorbed in bending of the finger plates.
