A turbine engine fleet wash management system is configured to electronically communicate with a turbine engine system, a fleet management service, and a cleaning management service. The turbine engine fleet wash system causes a cleaning of a turbine engine to occur based on information received from the turbine engine system and other sources. The turbine engine fleet wash management system includes a cleaning schedule optimizer that generates a cleaning schedule based on engine health monitoring data, engine operation data, maintenance schedules for the turbine engine, and cleaning regimen data. The cleaning schedule optimizer estimates turbine engine performance improvements based on the selected cleaning regimen, and calculating an estimate of carbon credits earned based on the predicted improvement in turbine engine performance.

A system for connecting an ultraviolet (UV) lamp with an electrical coupling includes a braid attachment coupled to the UV lamp, and one or both of a compressive wrap secured around at least a portion of the braid attachment, or a clamp secured around at least a portion of the braid attachment.

An aircraft includes an interior and an environmental system configured to circulate air through the interior. The aircraft also includes at least one disinfectant dispenser configured to dispense a disinfectant in the air circulated through the interior.

An ultraviolet (UV) light shield system includes multiple UV lamps mounted within an internal cabin of a vehicle. The UV lamps are positioned to emit UV light in fields of illumination that extend along sides of passenger seats disposed within the internal cabin. Two adjacent fields of illumination are spaced apart to define a protection zone for a passenger sitting on one of the passenger seats.
