Abstract:
A deployable vortex generator attached to a lifting surface includes a vane moveable relative to the lifting surface. The vane moves from a deployed position to a retracted position in response to a change in ambient conditions. In the deployed position, the vane acts on the air flow to create vortices. In the retracted position, the vane is closely aligned with the free stream velocity.
Abstract:
Systems and methods for mitigating constraints associated with wireless power transmission in applications where the position and orientation of the desired magnetic field changes over time, for example, because the position and orientation of the receiver being powered changes over time or because different receivers having different positions and orientations are being powered at different times. In accordance with some embodiments, the system employs a plurality of wireless power transmitters in a defined space, each transmitter consisting of individual coils oriented orthogonally relative to each other. Using field interference amongst these individual coils as well as amongst the transmitters they form, one can actively control the wireless power field intensity and orientation at any given point in the defined space. This allows for methods to steer the power transmission towards a specific target at a specific angle.
Abstract:
Systems and methods according to one or more embodiments are provided for reducing noise levels in a passenger cabin of an aircraft. In one example, an aircraft includes a wing coupled to a fuselage. The wing is configured to heat air to provide a first stream of air from a central portion of a wing segment of the wing extending between the fuselage and a first engine of an aircraft. The first stream of air is at a higher temperature than an adjacent stream of air from the wing.
Abstract:
A method for capturing hyperspectral images using a regular color camera. In the method, the camera takes multiple images of a scene, with the camera oriented differently for each image. For a camera carried by an aircraft or spacecraft, this allows hyperspectral imaging without the cost or weight of a hyperspectral camera.
Abstract:
A method and apparatus for managing a location. Soil sensor units are deployed in the location in a forest from a group of aerial vehicles. Information is generated about a number of soil conditions in the location in the forest using the soil sensor units in the location. The information is transmitted from the soil sensor units to a remote location for analysis.
Abstract:
An air vehicle may include a body having forwardly-swept fixed wings or unswept fixed wings. The body may have a longitudinal axis continuously oriented parallel to a forward flight direction when the air vehicle is in flight. The air vehicle may include at least one of the following components being mounted on opposite sides of the body: longitudinally offset engine nacelles, asymmetrically lengthened engine nacelles, and longitudinally offset protruding aerodynamic surfaces comprising at least one of stabilizers, canards, empennage control surfaces, external stores, and high aspect ratio wings.
Abstract:
A turbulence and winds aloft detection system may include an image capturing device for capturing a plurality of images of a visual feature of a selected celestial object; and an image processor configured to compare the plurality of images of the visual feature to detect a transit of a turbule of turbulent air between the image capturing device and the selected celestial object; compensate for one or more of apparent visual motion of celestial objects due to a planet's translation and rotation, the moon's revolution about the planet, and the atmosphere's refractive displacement of celestial objects; and compute a measurement of at least one of a velocity of the turbule and a height of the turbule relative to the planet.
Abstract:
A method and apparatus for identifying a position of a surface on an aircraft. Image data for an image of the surface on the aircraft is received. The image data is processed to determine whether the position of the surface on the aircraft is a desired position. A surface position identification report comprising information identifying whether the position of the surface on the aircraft is the desired position is generated.
Abstract:
An apparatus for inhibiting heating of an enclosure is disclosed. The apparatus comprises a covering configured to shade at least a portion of a surface of the enclosure and includes a plurality of retroreflective elements. The plurality of retroreflective elements are configured to retroreflect electromagnetic beams primarily at wavelength in a range between about 380 nm and about 780 nm or sub-range thereof. The plurality of retroreflective elements receive the electromagnetic beams along beam entry paths and reflect the electromagnetic beams along beam exit paths. The beam entry paths and the beam exit paths have substantially the same elevation angle and may also have substantially the same azimuthal angle. Further, the plurality of retroreflective elements may include retroreflective elements configured to diffusively and/or specularly scatter audible sound wavelengths, RF wavelengths, and/or thermal infrared energy.
Abstract:
An enhanced control system for an unmanned aerial vehicle adds constraints to the process of choosing a flight path in the event of an in-flight contingency, such as engine out or an encounter with jamming, which forces a diversion or unplanned landing. The constraints are: (1) ensure communications are available when needed during contingency operations; and (2) ensure signals from a global positioning system (or other navigation system) are available when needed during contingency operations.
