A method and a system for recycling spent ethylene or propylene glycol recovered from aircraft deicing solutions is described. The recovered spent ethylene or propylene glycol contains water and other undesirable substances which require to be removed to produce a solution free of these substances which can be further processed to remove substantially all of the water content and to blend-in additives required to certify the final glycol solution for aircraft deicing. The method and system employs a computer controller for continuous automatic batch processing of the spent glycol, including, in combination, filtering, distillation, blending and testing in specific sequences and achieves an improved quality recycled glycol of a purity of at least 99.5% and preferably between 99.6% to 99.9% glycol concentration.

A method for applying a fluid, such as deicing fluid, to a surface of an airplane. A vehicle loaded with a fluid has a nozzle for spraying said fluid onto said surface and at least one sensor and a processing unit is provided for determining a 3D representation of the surface onto which fluid is to be added. The 3D representation is used to determine boundary conditions for a path along which the nozzle is moved relative to the surface and the fluid is being dispensed onto the surface as said nozzle is being moved along the path.

A smart fluid application system and method for the delivery of a fluid to a discreet location is disclosed in the present application. The system and method utilize a rigidly affixed port block with multiple discharge ports, where each port has at least two apertures, all of which are positioned and designed to dispense a fluid only to a pre-determined location. At least one sensor detects an event and directs the release of fluid through a specific port and ceases the release when the event is ended. Such a system and method may be used anywhere a precise application of fluid is required.

For deicing an aircraft, a deicing system includes a base, a plurality of motorized wheel assemblies, a proximal deck and a distal deck, and a plurality of articulated arms. The base may have a length along the longitudinal axis that is substantially equivalent to a specified aircraft. The plurality of motorized wheel assemblies is disposed under the base. A movement direction of each wheel assembly is rotatable about a vertical axis. The plurality of articulated arms is disposed on the proximal deck in the distal deck. A shell is disposed on the end of each articulated arm. The plurality of motorized wheel assemblies moves the deicing system adjacent to the aircraft and the plurality of articulated arms each position a shell adjacent to the aircraft.

The present discloses a system for washing and de-icing of aircrafts. The preset invention provides a hangar comprising three gantries to ensure different steps of the washing or the de-icing process. The structure of the gantries is essentially made of telescopic arms allowing more flexibility on the positioning of nozzle clusters during the washing and de-icing process. The use of such a mechanical system is easily accommodated to different aircraft bodies regardless their sizes. The whole functionality and positioning of the system is ensured by a programmable system.

The present disclosure provides an airplane ground deicing installation that minimizes the impact of deicing operations on the airport during icing conditions. The installation does not require alteration of a normal taxi pattern and can be performed as quickly as the average separation time between take-offs. The installation allows modification of its shape to adapt to the contour of almost all types of commercial passengers airplanes operating from major airports, and simultaneously deices large surfaces of the airplane. Deicing and anti-icing fluids are applied to airplane surfaces from nozzles positioned in close proximity to the airplane's surface. Speed and adaptability to different types of airplanes, combined with a design that allows rapid relocation of the installation, are key features that make it possible to place the installation on the taxiway, close to the head of the runway it serves, such that the taxi pattern and the separation in between takeoffs are not altered as compared to the normal operations of the airport.
