Abstract: A method of protecting a wind turbine having a set of blades, each blade having a set of loci suitable for placement of a corresponding set of lightning receptors, against lightning strikes, includes applying to each blade a coating that surrounds at least one lightning receptor locus of the set, wherein the coating comprises paint in which has been mixed a conductive powder having a concentration by weight in the coating sufficiently low as to prevent formation of a conductive path through the coating but sufficiently high as to foster ionization of air along the coated exposed surface.

Abstract: A lift control device actively controls the lift force on a lifting surface. The device has a protuberance near a trailing edge of its lifting surface, which causes flow to separate from the lifting surface, generating regions of low pressure and high pressure which combine to increase the lift force on the lifting surface. The device further includes a means to keep the flow attached around the protuberance or to modify the position of the protuberance in response to a command from a central controller, so as to provide an active control of the lift between a maximum value and a minimum value.

Abstract: A single dielectric barrier plasma actuator is disclosed which includes a pair of offset electrodes and a dielectric barrier therebetween which includes a catalyst at least in the area adjacent one of the electrodes for enhancing the force created in the background gas by the actuator.

Abstract: The disclosure is directed toward a central laser source based passive countermeasure system for use on an emission producing asset comprising at least one centrally located source disposed on the emission producing asset. The centrally located source is configured to produce optical energy in at least one band of infrared radiation. At least one first fiber optic wire is coupled to the centrally located source to transmit the optical energy. At least one modulator is coupled to the centrally located source via the first fiber optic wire and is configured to modulate a flow of the optical energy. At least one output lens assembly is coupled to the modulator via a second fiber optic wire and is configured to receive the optical energy and emit the optical energy.

Abstract: A method for generating visible light and a deceptive signature pattern for an emissions producing asset is disclosed. The method comprises illuminating at least one lighting assembly of the asset in a pattern. The pattern produces visible light synchronous with a signature of a wavelength in a substantially similar range as normal emissions of the asset. The method also comprises modulating a radiant intensity of the signature of the at least one lighting assembly between a minimum radiant intensity and a maximum radiant intensity in a repetitive cycle and operating a controller to regulate the pattern.
