The present invention provides a fixture or device which is particularly adapted for installation within a general aviation aircraft, such as a small private jet, prop-driven plane, helicopter, spacecraft, or other aviation vehicle, and which emits UV-C within safe limits, i.e., within prescribed safe wavelengths, irradiance, and times (below the ‘Actinic Dose’) while the aircraft is occupied, to continuously disinfect the interior air and prevent transmission by not only the COVID-19 virus but other viruses as well. The device, generally, comprises a two-piece or two-part assembly, having a base and a cover which mounts to the ceiling or wall(s) of an aircraft. A UV-C lamp, typically an LED, is disposed within the fixture and projects it therefrom into the cabin, as well as control-electronics to ensure safe emission limits by the LED.

Modules, systems and methods that disinfect surfaces using ultraviolet (UV) light are disclosed. In one aspect, a UV light-emitting module comprises an enclosure including an aluminum rear wall comprising a ventilation opening and a face plate spaced from the rear wall and comprising a light-transmitting aperture. Four aluminum sidewalls extend between the rear wall and the face plate, with at least one sidewall comprising a ventilation opening. At least one aluminum UV light emitter support within the enclosure is electrically coupled to plurality of UV light emitters. A thermally conductive and electrically insulating separator is located between the support and the rear wall. At least one electrical conductor extends through the rear wall and the separator into the support, and an electrically insulating bushing extends between the conductor and surfaces of the rear wall.

A method for disinfecting a water system of an aircraft includes letting-in of hot water at an inlet of the water system by a first ground service unit; flushing the hot water from the inlet, through water pipes of the water system, to an outlet of the water system; and letting-out of the hot water at the outlet, by the first ground service unit or a second ground service unit; the hot water being flushed into the inlet and out of the outlet over a predefined disinfection period; and the hot water being provided at the inlet via a continuous-flow heater of the first ground service unit.

Methods for refurbishing aerospace components by removing corrosion and depositing protective coatings are provided herein. In one or more embodiments, a method of refurbishing an aerospace component includes exposing the aerospace component containing corrosion to an aqueous cleaning solution. The aerospace component contains a nickel superalloy, an aluminide layer disposed on the nickel superalloy, and an aluminum oxide layer disposed on the aluminide layer. The method includes removing the corrosion from a portion of the aluminum oxide layer with the aqueous cleaning solution to reveal the aluminum oxide layer, then exposing the aluminum oxide layer to a post-rinse, and forming a protective coating on the aluminum oxide layer.
