Abstract

A morphing airfoil includes 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 bend in response to control inputs to change a lift force without separate movable control surfaces. A plurality of standoff mounts are attached to an inner surface of anisotropic skin. The standoff mounts include through apertures for receiving a flexible stringer. The anisotropic skin is attached to underlying structure through the flexible stringers. The flexible stringers interface with actuated position control ribs and passive compliant support ribs. 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 and drag distributions along a span of the airfoil without separate control surfaces.

Abstract

The present invention relates to a microfluidic flow process for making polymers, polymers made by such processes, and methods of using such polymers. In such process, a novel reagent delivery setup is used in conjunction with microfluidic reaction technology to synthesize anionic polymerization reaction products from superheated monomer orders of magnitude faster than is possible in batch and continuous syntheses. The aforementioned process does not require the cryogenic temperatures which are required for such syntheses in batch or bulk continuous. Thus the aforementioned process is more economically efficient and reduces the environmental impact of linear polymer production.

Abstract

A micro-cavity passive actuator is configured to delay dynamic stall of an airfoil. The micro-cavity actuator is formed in the pressure sidewall surface proximate the leading edge of the airfoil. This cavity remains essentially inactive at low incidence. However, as the wing's effective angle of attack dynamically increases and the stagnation point displaces past the micro-cavity, the accelerating flow grazing the cavity induces a high-frequency resonance phenomenon (known as Rossiter modes). The self-generated small-scale disturbances are carried around the leading-edge through the boundary layer to the wing's upper side where the laminar separation bubble (LSB) amplifies these disturbances. This process delays LSB bursting and dynamic stall. The micro-cavity must be sized such that its naturally emitting oscillations are in a range of frequencies that can be amplified by the LSB.

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.

Abstract

Systems and associated methods for constructing neural networks (NN) without the benefit of predefined output spike times or predefined network architecture. Functions are constructed from other functions determined from an input construction training set of output variable type. Method aspects of the neural network modeler may comprise partitioning the construction training set, representing the partitions, restricting the representations, constructing subfunctions from the restrictions, and combining the subfunctions to model the target function. Specifically, subfunctions represented from partition-specific neural networks of output value type are created using two fundamental composition operations: same-constant composition and different-constants composition. Different choices of weights and delays lead to different NNs with different output spikes that implement the same function.

Abstract

An acoustic imaging system responsive to an acoustic wave emitted from an object is disclosed. The system detects a deflection angle of an electromagnetic probe beam as it passes through a coupling element.

The probe beam deflection angle is related to an angle of propagation of the acoustic wave through the coupling element. A filtering unit is configured to remove components of the signal from the acoustic detector that are outside of a range of angles, thereby improving the angular resolution of the acoustic detector. The acoustic wave may be generated by an acoustic source, such as an ultrasound transmitter, or an electromagnetic source such as a laser.

Abstract

A method of establishing a system for gathering surveillance data in a hostile environment. The method comprises the steps of providing a movable tractor for ground hauling a trailer, and providing a drone which can be operated independently from the tractor. The trailer has a floor pan for supporting a relay sensor dispensing mechanism and a platform above the floor pan, with a hole for dispensing relay sensors therethrough. The relay sensor dispensing mechanism has an elevator for holding a stockpile of relay sensors, and elevating the relay sensors through the hole. The method comprises disposing at least one relay sensor in the elevator, elevating the relay sensor to a pickup position at or above the platform and retrieving the relay sensor with a drone for subsequent deposition in the hostile environment. The relay sensor then gathers and transceives surveillance data for use and interpretation by an operator. Optional a conveyor chute may replenish the elevator when it is depleted of relay sensors.

Abstract

The present invention relates to a microfluidic flow process for making polymers, polymers made by such processes, and methods of using such polymers. In such process, a novel reagent delivery setup is used in conjunction with microfluidic reaction technology to synthesize anionic polymerization reaction products from superheated monomer orders of magnitude faster than is possible in batch and continuous syntheses. The aforementioned process does not require the cryogenic temperatures which are required for such syntheses in batch or bulk continuous. Thus the aforementioned process is more economically efficient and reduces the environmental impact of linear polymer production.
