Wands are used as parts of cleaning systems to conduct cleaning agents into gas turbine engine cores. Wands according to the present disclosure include inlet assemblies adapted to connect to cleaning agents, dispensers adapted to discharge cleaners into gas turbine engines, and conduits that extend from the inlet assemblies to the dispensers.

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.

A self-cleaning floor assembly is configured to form or be positioned on a floor of an enclosed space. The self-cleaning floor assembly includes a moveable floor including a moveable floor panel, an actuation system that is operatively coupled to the floor panel, and a cleaning system proximate to at least a portion of the moveable floor. The actuation system is configured to move at least a portion of the floor panel into and through the cleaning system during a cleaning cycle. The cleaning system is configured to clean the portion(s) of the floor panel during the cleaning cycle.

The disclosure describes a method for disinfecting an aircraft cabin that includes injecting a non-peroxide disinfectant into an environmental control system of an aircraft and discharging cabin supply air through the environmental control system to discharge the non-peroxide disinfectant into the aircraft cabin. In some instances, the method includes aerosolizing the disinfectant into a plurality of liquid droplets while injecting the disinfectant into the environmental control system. In some instances, the injected disinfectant includes a non-corrosive, non-toxic disinfectant, such that the disinfectant may be discharged into the aircraft cabin in the presence of personnel in the aircraft cabin.

This document describes a system and method through which unmanned aerial vehicles (UAVs) can be docked, with a device that can secure the UAVs, and information can be transmitted to and from such UAVs. The UAVs are secured through the use of magnetic fields. The system also includes a means for transmitting information between the docking system itself, the UAV(s) and/or between the docking system and a command center, which may be a notable distance from the docking system, or among the docking system, the UAV(s) and the command center.

A collection apparatus for collecting waste from cleaning operations performed on an aircraft turbine engine includes a frame structure, a support arm having a first end movably attached to the frame structure and an opposite second end, an actuator device adapted to enable raising and lowering the support arm, a waste storage tank, a duct having an inlet end and an opposite outlet end adapted to be removably connected to the waste storage tank, and a flexible duct portion having a flexible portion inlet end and a flexible portion outlet end. The inlet end of the duct is adjustably supported by the second end of the support arm. The flexible portion outlet end engages the inlet end of the duct in fluid communication, and is bendable both up/down and sideways and is expandable in length between the flexible portion inlet end and the flexible portion outlet end.

A system for centrally controlled sanitization of a lavatory of an aircraft using ultraviolet (UV) light includes a first UV light source configured to emit a first UV light, and a second UV light source configured to emit a second UV light. The system further includes a central controller coupled to the first UV light source and the second UV light source and configured to independently control the first UV light source and the second UV light source to emit the first UV light and the second UV light at least one of at different times or for different durations.

A system for touchless control of a lavatory of an aircraft includes at least one sensor located in the lavatory and configured to detect detected data corresponding to the lavatory. The system further includes at least one actuator or light source located in the lavatory and configured to perform an action. The system further includes a central controller coupled to the at least one sensor and the at least one actuator or light source and configured to make an inference based on the detected data and to control the at least one actuator or light source based on the inference.

An unmanned ground-based hygiene maintenance vehicle, UGV, includes a housing with a base plate, top plate and housing side wall substantially perpendicular to the base plate. Arranged in the housing is at least one wheel drive coupled to at least one wheel in a recess in the base plate. The UGV includes sensors for sensing the environment of the UGV, and a controller for autonomous location and navigation of the UGV based on sensing parameters of the sensors. The UGV includes an articulated robot arm on the top plate of the housing and to support a hygiene maintenance tool. The UGV includes at least one load-receiving element coupled to the housing side wall and extending outwards from the housing side wall, wherein the load-receiving element includes a load support surface for supporting a hygiene maintenance tool supply module with respect to a vertical direction extending transverse to the base plate.
