A method of sanitizing a passenger cabin includes excluding people from the passenger cabin and substantially sealing the passenger cabin such that air inside the passenger cabin is prevented from exiting the passenger cabin. An ozone enriched atmosphere is created inside the passenger cabin by generating ozone and directing the ozone into the passenger cabin to increase an ozone concentration of the atmosphere inside the passenger cabin to at least a minimum concentration. The ozone enriched atmosphere is circulated through the passenger cabin and air circulation system thereof for a sanitation period calculated to be sufficient for sanitation. The ozone concentration of the atmosphere inside the passenger cabin is then reduced to a level safe for human occupation.

A cabin disinfection system for an aircraft, including: a sensing means (3, 11, 13) to sense the presence of personnel in one or more zones (16-19, 23-26, 28, 29, 30, 32), a predictive sensing means (3, 11, 13, 33) to sense the direction of motion of a person (31) and to predict whether that person will occupy a zone to be disinfected (18) during planned disinfection, one or more UVC radiation sources (4, 9) to disinfect the cabin, and a controller (33) to control operation of the UVC radiation sources (4, 9) dependent on sensing of personnel in that zone and the predictive sensing means (3, 11, 13, 33) predicting that a person (31) will occupy the zone (18) during the planned disinfection period.

A purging system for a laminar flow control system comprises an air scoop and a diffuser fluidly connected thereto. The air scoop is disposable into an external flow of an external atmosphere. The diffuser is configured to fluidly connect the air scoop to a suction cavity of the laminar flow control system wherein the suction cavity may be disposed adjacent a porous skin of an airfoil such as adjacent a leading edge of the airfoil. The laminar flow control system may be configured to suction boundary layer flow passing over the porous skin by drawing a portion of the boundary layer flow through a plurality of pores formed in the porous skin. The diffuser ducts high pressure flow captured by the air scoop to the suction cavity for discharge through the pores to reduce the potential of blockage thereof.

A vehicle includes an internal cabin, and an autonomous cleaning system located within an interior chamber of the internal cabin. The autonomous cleaning system includes a cleaning robot configured to clean a portion of the interior chamber.

The present invention relates to apparatus and methods of removing media. In particular, the present invention relates to apparatus and methods of removing media from a tooling for a fuselage. In one implementation, the media removal apparatus uses an auger to dislodge the media, and a vacuum to remove the media. In another implementation the media removal apparatus uses an air pressure line to dislodge the media and a vacuum to remove the media.

Spray array apparatus which includes a plurality of water and air carrying spoke members extending radially from a central fluid distribution assembly. The spoke members are connected to a plurality of water and air carrying strut members. The spoke members are divided into segments and the segments and strut members are detachably joined together by means of manifold joints which have water and air passageways allowing fluid communication between spoke segments and strut members. The apparatus is towed at the end of a boom of a tanker aircraft and is connected to the boom by means of a gimbal allowing two degrees of freedom to reduce bending moments and connection stresses. Selected fluid parameters are transmitted to the tanker aircraft to adjust fluid flow, if necessary.
