  • Patent number: 10662898
    Abstract: A thruster has an additively-manufactured housing that includes an integrally-formed nozzle with a burst disk in it. The housing is part of a casing that surrounds and encloses a propellant that is burned to produce pressurized gases that burst the burst disk and produce thrust. The thruster may be placed in a receptacle that defines a recess for receiving the thruster. The receptacle also may be additively manufactured. The thruster and the recess both may be cylindrical, with the housing being closely fit with the cylindrical walls of the receptacle. This may allow some of the structural loads on the housing, such as loads produced by the combustion of the propellant, to be transferred to the adjoining walls of the receptacle. This enables the housing to have less structural strength than if it were to have to contain the pressure from the propellant all on its own.

  • Patent number: 10654762
    Abstract: A combustible element includes regions of fuel material interspersed with regions of oxidizer material. The element may be made by additive manufacturing processes, such as three-dimensional printing, with the fuel material regions and the oxidizer material regions placed in appropriate locations in layer of the combustible element. For example, different extruders may be used to extrude and deposit portions of a fuel filament and an oxidizer filament at different locations in each layer of the combustible element. The combustible element may define a combustion chamber within the element, where combustion occurs when the combustible element is ignited. The fuel material and the oxidizer material may be selected, and their relative amounts may be controlled, such that desired relative amounts of fuel and oxidizer are present for combustion with desired characteristics, such as combustion rate.

  • Patent number: 10654550
    Abstract: Disclosed are an improved nozzle for an unmanned underwater vehicle (UUV), and a method for operating the same. The nozzle includes a first rigid member operatively coupled to a UUV steering mechanism. The nozzle also has a second rigid member, coupled to the first rigid member by a flexible bellows according to a configurable operating angle. The nozzle does not extend beyond a bounding surface when stored but does when deployed. Water traversing the first rigid member and contacting the second rigid member produces a reactive force according to the configurable operating angle. Simultaneous and independent control of the volume of fluid traversing several such nozzles in the UUV, and their respective orientations and operating angles, permits automatic station-keeping or navigation according to another guidance objective.

  • Patent number: 10656235
    Abstract: The concepts, systems and method described herein provide direction finding (DF) methods based on a minimum distance (MINDIST) search to principal components. In an embodiment, the method includes capturing samples of data from one or more array elements. The samples may be samples of a signal received at the array elements. The method includes generating a spatial sample covariance matrix (SCM) using the samples of data, extracting principal components from the SCM and generating a principal component table using angle and frequency measurement for each of the principal components. The method further includes determining a distance between a test point and each value in the principal component table and identifying a minimum distance point corresponding to a direction of the received signal. The minimum distance point may correspond to direction of arrival of a signal on the one or more array elements.

  • Patent number: 10649051
    Abstract: A system and method for detecting a nucleus of interest in a chemical using a nuclear quadrupole resonance transition. An excitation pulse is used to excite one or more nuclei of interest, if they present in a sample, to an excited state, the energy of which depends on the magnetic field in the sample. The magnetic field in the sample is modulated, after the end of the excitation pulse, while the nuclei of interest decay from the excited state, so that the radiation they emit is frequency modulated. The frequency modulation is detected in the emitted radiation. In some embodiments a DC magnetic field is applied to the sample, during the application of the excitation pulse, to tune the frequency of the transition being excited.

  • Patent number: 10644523
    Abstract: A charge management system including a power distribution bus circuit for distributing energy from a power source to a load, and an intermediate energy storage circuit operably connected to a power distribution bus circuit for aiding in distribution of energy to the load. A charge management system controller may be configured to control the discharge of energy between the intermediate storage circuit and the power distribution bus circuit during one or more modes. Such a charge management system may enable the power distribution bus circuit to receive energy from the intermediate energy storage circuit before the power bus voltage drops in response to load demand, which may enable the power source to respond to perturbations in the power bus voltage and minimize inrush current from the power source. The system also may be used to soft-start high-power equipment, or absorb energy spikes associated with shut-down.

  • Patent number: 10641585
    Abstract: An automated system and method provides for planning and response to disparate threats with combined kinetic (e.g., missile interceptor) and non-kinetic (e.g., cyber and electronic warfare) effects. The threat and effects inputs and the results of analysis tools that individually apply a single effect type to negate a threat vulnerability are normalized to a form and format ingestible by a Stochastic Math Model (SMM). The normalized inputs reflect the success/failure of the effect versus a threat vulnerability as a score, not a probability. The normalized results decompose a probability of defeat (Pdefeat) for an individual effect as a set of hierarchical parameters represented as probabilities.
