  • Patent number: 11946832
    Abstract: A portable tracer fluid injection system. The system has a vapor cloud generator which vaporizes a vapor cloud generating liquid. The vapor cloud generator is uses a sub-ohm resistive heater to vaporize small volumes of the vapor cloud generating liquid, allowing for a relatively small tracer fluid injection system. This system has the benefit of being able to target specific regions of a test object within a wind tunnel and being usable for different positions within the test section of a wind tunnel.

  • Patent number: 11931881
    Abstract: A tool box with vertically stacked monolithic trays. Each tray has pockets specifically shaped to receive complementary tools. The trays have upstanding cantilevered posts, which can space apart the superjacent tray. Alternatively, the posts can be received in complementary sockets of superjacent trays to prevent undue lateral movement while in the tool box. The post and socket geometry can be constructed to index the order in which trays are stacked and index how individual trays are oriented for optimal and sequenced access to the tools.

  • Patent number: 11932389
    Abstract: The present disclosure defines a morphing airfoil having a dynamic flexible skin system that is capable of carrying high level aerodynamic (or fluid) pressure loads over a structural surface. The structural surface can morph and deflect in response to control inputs to change a lift force without separate movable control surfaces. The anisotropic skin is attached to underlying structure that is both actively controlled and passively supported. A control system causes the underlying support structure to move to a desired location which in turn causes the skin to bend and/or flex without exceeding a stress threshold and thus vary the lift profile along a span of the airfoil.

  • Patent number: 11933694
    Abstract: An instrumented wind tunnel. The wind tunnel receives a test subject which can be a model of an object to be tested with dynamic airflow. The test subject is fitted with at least one sensor to deliver data to a chassis, which in turn uses a network having at least 10 Gb/s capability to deliver the data to a RAM cache. The RAM cache can push the data to multiple viewers for real time monitoring of wind tunnel tests. The operator can then make live adjustments of the test conditions.

  • Patent number: 11891951
    Abstract: A scramjet engine with a novel isolator is disclosed herein. The scramjet includes an air inlet configured to receive and direct air into the engine and a combustor operable to receive air from the air inlet and combust fuel therein as is conventional. An isolator is positioned between the air inlet and the combustor. The isolator includes a primary flow path separated into a plurality of separate secondary flow channels formed therethrough. The smaller secondary flow channels prevent shockwaves from propagating upstream from the combustor to the inlet that can occur during some operating conditions of a supersonic combustion flow process.

  • Patent number: 11888403
    Abstract: A galvanic isolator circuit and method provide for galvanically isolating and current limiting a power source from a load. A direct current (DC) input voltage (“vin”) and an input current (“iin”) are received. A full- or half-bridge rectifier is switched to synthesize a first alternating voltage waveform that magnetically couples through a transformer to induce a second alternating voltage waveform with galvanic isolation from the first alternating voltage waveform, preventing potentially-faulted load from a source. The second alternating voltage waveform is rectified to produce a direct current (DC) output voltage (“vo”) having output current (“io”) through more than one drive transistor or diode. The more than one primary-side drive transistor is current limited to reduce or prevent brown-out, black-out, or protective race conditions in the non-faulted portions of DC power generation systems and DC distribution electrical power systems.

  • Patent number: 11885870
    Abstract: The present application discloses a new form of ?-STAP, referred to herein as post ?-STAP or P?-STAP, which overcomes the drawbacks associated with existing ?-STAP techniques. The P?-STAP techniques described herein facilitate the generation of additional training data and homogenization after pulse compression. For example, P?-STAP techniques may apply a plurality of homogenization filters to a pulse compressed datacube generated from an input radar waveform, which produces a plurality of new pulse compressed datacubes with improved characteristics. Unlike existing ?-STAP techniques described above, which require pre-pulse compressed data to operate, the P?-STAP techniques disclosed in the present application are designed to utilize pulse compressed data, and therefore may be readily applied to legacy radar systems.
