Abstract: An anti-phase rotor system for an aircraft may include at least one rotor with at least two rotor blades. The aerodynamic profile of these two blades may be selected to create counteracting blade vortices to break up harmonic reinforcement due to the rotor blade passage. The aerodynamic profile may create a non-planar motion of one or more rotor blade passages, whereby the individual rotor blades are not co-planar during the rotation of said rotor. The rotor system may include a duct, which may include stationary vanes or struts configured in a manner so as to break up harmonic excitation to the rotor. The interior area of the duct at the area of the blade rotation may be designed in a manner so as to create a destructive rotor blade tip vortex interference.

Abstract: A method of coating a substrate with a white molecular coating. A colloidal based primer is prepared having on a mass basis between 30-40% suspensions of fine-sized spherical particles of nonporous silica dispersed in liquid phase. The primer is applied to the substrate and allowed to dry. A molecular adsorber coating is prepared by treating a zeolite with a colloidal silica binder thereby providing a treated pigment having a mass ratio of the colloidal silica to the zeolite is in a range of 2.0 to 2.6, then processing the treated pigment into a powder thereby facilitating sprayability and then mixing said treated zeolite with a colloidal solution containing silica. The coating is then sprayed onto the primer and allowed to dry. The resultant coating provides adequate bond stability and strength necessary for flight applications within an environment for vacuum of space applications.

Abstract: System and methods for risk and risk precursor identification in commercial aviation operations according to various aspects of the present invention operate in conjunction with a source of operation flight track data, a set of risk determination models containing instructions on how to process a set of received operational flight track data, a risk determination API for activating one or more risk models to process the set of received operational flight track data, and a user interface for communicating with the risk determination API. Each risk model may be trained to analyze flight track data to identify a particular type of risk precursor or identify a type of risk and any precursors that led to the risk. Processed results and identified risk precursors are forwarded to the user interface and displayed to allow users to quickly distinguish between nominal conditions for an aircraft and conditions with elevated levels of risk.

Abstract: Various embodiments provide ice mitigating surface coatings and methods for applying ice mitigating surface coatings. Various embodiment ice mitigating surface coatings may be formed by hydrolysis of one or more substituted n-alkyldimethylalkoxysilanes terminated with functionalities having the following characteristics with respect to water: 1) non-polar interactions; 2) hydrogen bonding through donor and acceptor interactions; or 3) hydrogen bonding through acceptor interactions only. The substituted n-alkyldimethylalkoxysilanes of the various embodiments may include methyl terminated species, hydroxyl terminated species, ethylene glycol terminated species, and methoxyethylene glycol terminated species. Various embodiment ice mitigating surface coatings may be applied to metal surfaces, such as aluminum surfaces. Various embodiment substituted n-alkyldimethylalkoxysilanes may have an aliphatic chain that is saturated and liner or branched or that is partially unsaturated and liner or branched.

Abstract: A multi-spectral imaging system utilizing tunable optics is disclosed. Various disclosed systems include a tunable optical filter coupled to a broadband imaging system. The tunable optical filter allows discrete infrared wavelengths to pass to the broadband imaging system so that monochromatic infrared images of a scene may be captured. An image processing system may process selected monochromatic infrared images by using a ratio technique to generate an emissivity-independent thermal image of the scene. The tunable optical filter may also be used to adjust a quality factor and control an amount of radiated energy that is passed to an image sensor of the broadband imaging system thereby acting as an aperture to account for both low and high radiance portions of the scene.

Abstract: An aircraft wing configuration for a vertical or a short take-off and landing aircraft having a plurality of propeller-blown wings mounted at different longitudinal locations along a fuselage of the vertical take-off and landing aircraft, producing two or more lifting surfaces, fixed at a predetermined acute wing angle greater than 0° and substantially less than 90° relative to a horizontal plane, and having a plurality of flaps disposed behind the wings. The configuration has a plurality of propellers distributed in front of the plurality of wings producing two or more lifting surfaces and mounted such that the wings are externally blown by forced airstreams from the propellers. The propellers produce distributed thrust components, and the plurality of flaps are in the forced airstreams of the propellers when one or more of the flaps is in an extended position.

Abstract: A statistical audibility prediction (SAP) method for predicting the audibility of a signal over time at a listening location, the signal from a signal source in the presence of a concurrent masking sound or masker from a masker source. The method includes receiving, via a processor over a plurality of auditory channels, a specific loudness of the signal and masker at the listening location. The method includes calculating for each auditory channel a standard deviation of a distribution of the specific loudness of the signal and masker, and calculating, via the processor, corresponding channel-specific detectability indices (d′t,i) for each auditory channel as a function of their standard deviations. The corresponding channel-specific detectability indices are then summed to produce a total detectability index (d′t), which may be output as an electronic signal that indicates the predicted audibility vs. time, e.g., to a downstream process and/or system or offline.

Abstract: Methods and systems are described for delivering psychophysiological self-regulation training in a virtual, augmented, and/or mixed reality environment that simulates a social situation, such as one involving conflict. A user (e.g., a trainee) may interface with a training computing system directly or via an avatar that may interact with other characters in the simulation who may be programmed at one or more levels of threat to or cooperation with the trainee. The system may provide feedback to the trainee regarding their cognitive and emotional states. The feedback may be designed to encourage them to develop the ability to respond in future real environments with appropriately effective states, where the feedback may take the form of the behavior of the characters, with the trainee's interaction based on their effective states being rewarded by desirable character behavior and the trainee's ineffective states being penalized by undesirable character behavior.
