Abstract

An apparatus for rapid, efficient and safe de-icing and cleaning of primarily aircrafts. A de-icing and cleaning system, includes one or more devices for spraying the object in question, preferably aircrafts, with a liquid or gas or irradiating the object, and includes a mechanism for sensing the position of the object relative the devices, and is disposed for controlling the devices to automatically start and stop the spraying and irradiation in response to the position of the aircraft relative the devices.

Claims

1. An apparatus for de-icing and cleaning aircraft comprising:

first and second stationary stations for accommodating the sequential passage of said aircraft from said first station to said second station, and for application for first and second discrete treatments, respectively, to said aircraft;

means disposed within said stationary stations for spraying said aircraft with liquid;

means for supporting said spraying means which comprises a corridor having an opening substantially similar to a frontal profile of said aircraft for allowing the passage of said aircraft through said stations;

said support means comprising conduits connected to said spraying means and forming a rigid frame in the form of a substantially closed loop defining said corridor;

wherein a lower part of said frame in at least one of said first and second stationary stations is disposed beneath the roadway on which the aircraft is moving through the station for encompassing all the exterior surface portions of said aircraft such that said spraying means treats substantially all said exterior surface portions of said aircraft;

first and second separate drainage systems operatively associated with said first and second stationary stations, respectively for separately collecting said liquid;

one or more means provided along the movement path of the aircraft for sensing the position and motion at any moment of said aircraft relative to said stations; and

means for automatically controlling said spraying means in response to said sensing means.

2. The apparatus of claim 1 wherein said spraying means further comprises

a plurality of spraying members connected to said conduits;

and

a plurality of valves connected with said conduits and said spraying members.

3. The apparatus of claim 1 further comprising:

means for spraying gas on said aircraft operatively connected with said controlling means.

4. The apparatus of claim 1 further comprising:

nozzles adapted for spraying steam on said aircraft operatively associated with said controlling means.

5. The apparatus of claims 1 or 2 wherein said rigid frame further comprises a vertically adjustable rigid frame.

6. The appartus of claims 1, 2 or 3 wherein said sensing means are operatively associated with said spraying means so as to directly control said spraying means by effecting selective controllable spraying of said aircraft.

7. The apparatus of claims 1, 2 or 3 further comprising programming means operatively associated with and controlled by said sensing means and operatively associated with said spraying means to control said spraying means to effect selective controllable spraying through said spraying means.

8. The apparatus of claims 1, 2 or 3 further comprising means for sensing wind velocity and wind direction, said wind sensing means being operatively associated with said spraying means such that said wind sensing means partially controls said spraying means.

9. The apparatus of claim 1 further comprising means interconnecting said stations wherein said drainage systems are disposed beneath said interconnecting means.

10. The apparatus of claim 1 wherein said spraying means are rigidly disposed within said stationary stations.

11. The apparatus of claim 10 wherein said supporting means are rigidly disposed within said stationary stations.

12. The apparatus of claim 1 wherein a portion of said spraying means are disposed within a lower surface portion of said corridor such that substantially all lower exterior surfaces of said aircraft are encompassed by said spraying means.

13. The apparatus of claim 1, wherein said spraying means in said first stationary station further comprises means for spraying a heat carrying medium and said spraying means in said second stationary station further comprises means for spraying a freezing point depressant to prevent the freezing of any liquid remaining on said aircraft.

14. The apparatus of claim 1, wherein said spraying means in said first stationary station further comprises means for spraying on said aircraft a dirt-dissolving detergent and said spraying means in the second stationary station further comprises means for spraying a liquid for rinsing said detergent from said aircraft.
