  • Publication number: 20230202646
    Abstract: Disclosed are methods and apparatuses for mitigating the formation of concentrated wake vortex structures generated from lifting or thrust-generating bodies and maneuvering control surfaces wherein the use of contour surface geometries promotes vortex-mixing of high and low flow fluids. The methods and apparatuses can be combined with various drag reduction techniques, such as the use of riblets of various types and/or compliant surfaces (passive and active). Such combinations form unique structures for various fluid dynamic control applications to suppress transiently growing forms of boundary layer disturbances in a manner that significantly improves performance and has improved control dynamics.

  • Publication number: 20210318847
    Abstract: An apparatus for generating audio synchronized optical output is provided. The apparatus comprises an input channel to receive an input signal from an audio source and a controller. The controller is configured to receive the input signal from the input channel, analyze the input signal to determine one or more characteristics of the input signal. The apparatus associates the determined one or more characteristics of the input signal to one or more parameters of an optical output from an optical source and modulates the one or more parameters of the optical output in accordance with the one or more characteristics of the input signal. The system for generates real-time audio and/or performance synchronized optical outputs and enables connecting stage implements, musical instruments, lights, visual effects, lasers and other theatrical effects to be controllable by lighting data from human interactions with musical instruments or other stage or human interface devices.

  • Patent number: 10479688
    Abstract: A tube manufacturing system is provided that is capable of manufacturing tube structures that are on the nanoscale and larger. The system provides for control as to the structure and atomic makeup of the feed sheet material used and provides motive force to the sheet material being used to continuously advance the sheet material through the various system components. After the tube structures are formed, they may be used in providing a source material for manufacturing macroscopic objects thus increasing the level of performance and capabilities of such objects due to the engineered properties of the tube structures formed within this system and method of manufacturing. Processes for manufacturing of nanotubes are also disclosed, as are nanotubes manufactured by the processes and system of the invention.

  • Publication number: 20190047685
    Abstract: Aircraft landing gear comprised of a wheel hub motor/generator includes alternating rotors and stators mounted with respect to the wheel support and wheel. The invention in certain embodiments can provide motive force to the wheel when electrical power is applied, e.g. prior to touch-down, thus decreasing the difference in relative velocities of the tire radial velocity with that of the relative velocity of the runway and reducing the sliding friction wear of the tire. After touchdown the wheel hub motor/generator may be used as a generator thus applying a regenerative braking force and/or a motorized braking action to the wheel. The energy generated upon landing may be dissipated through a resistor and/or stored for later use in providing a source for motive power to the aircraft wheels for taxiing and ground maneuvers of the aircraft. Methods and apparatuses for nose gear steering and ABS braking using the disclosed invention are described.
