Abstract
An aircraft de-icing system has a nozzle with at least one movable element configured to move between a first position and a second position to change a spraying configuration of the nozzle between a first configuration and a second configuration. The aircraft de-icing system further has at least one storage reservoir configured for containing a de-icing agent and a pump for pumping the de-icing agent from the at least one storage reservoir to the nozzle. The aircraft de-icing system further has a pressurized air source in fluid communication with the nozzle for delivering pressurized air to the nozzle. The nozzle is configured for selectively mixing varying amounts of the pressurized air and varying amounts of the de-icing agent to provide a spray pattern for application on a surface of an aircraft based on a position of the at least one movable element between the first position and the second position.
