An aircraft maintenance robot (20) for maintaining aircraft surfaces is described, that includes a maintenance tool (228), for example a nozzle (78), conduits and a pump, which supply fluid to the maintenance tool, which sprays the fluid on aircraft surfaces; movable arm with rotatable hinges and wrists such that a manifold to which the maintenance tools are coupled may be positioned in response to control signals; and a processor which, after accounting for the position of the aircraft, the weather conditions, and the physical dimensions of the aircraft, generates the control signals used to position the maintenance tool such that, after positioning the aircraft, the maintenance operation may be performed without human intervention. The preferred embodiment of the present invention discloses the use of the maintenance robot (20) for deicing aircraft. A wide variety of interchangeable end effectors, however, may be used for a wide variety of applications. These may include various cleaning, painting, paint removing, and even firefighting applications.

An apparatus and method are provided for use in removal of coatings from airplanes and the like wherein such removal requires the application of a solvent composition for dissolving the coating such as paint, the solvent having a sufficiently high vapor pressure to be present in both a liquid phase and a gaseous vapor phase at stripping temperatures with the solvent in the vapor phase being lighter than the liquid phase and heavier than air, and the apparatus including a portable carriage, positionable beneath the airplane, a receptacle having spaced side walls and carried by the carriage, the side walls extending vertically upwardly, the receptacle further defining a receptacle bottom portion, the receptacle receiving spent solvent in both the liquid and the vapor phases after application of the solvent to the airplane surfaces and dissolution of the paint therein, the side walls directing the received spent solvent in both phases to the receptacle bottom portion such that vapor phase is trapped above the heavier liquid phase by the lighter air thereover, and an exhaust port located above the receptacle bottom portion for removing the vapor phase.

摘要:
A plant for de-icing especially surfaces of aeroplanes, comprising the use of at least two sources (10, 12) of liquid media that are different from each other and capable of being sprayed separately or as a mixture, comprising a number of positive liquid pumps (16, 22) corresponding to the number of media, which pumps all have the same capacity or a predetermined interrelated capacity ratio and terminate in a common spray pipe (24). The connection of the liquid pumps to the sources includes at least one of the sources to at least one of the liquid pumps. In a hydraulic system comprising hydraulic motors (56, 52) for driving the liquid pumps (16, 22) at least two of motors are connected to a common hydraulic pressure pump (32) controlled by way of pressure compensation (33) to work with at least two pressure stages subject to a ratio corresponding to that of the capacity of at least one liquid pump to the total capacity of both liquid pumps. In such a plant the compostion of the spray liquid to be dispensed is determined solely by the capacity of the liquid pumps, thereby eliminating any throttling effects which may cause the de-icing medium to coagulate.

The assembly includes a plurality of flexible and inflatable bags 43, 44, 45, 46, 47, 48, 56 and 58, each having a rectangular cross section with an open end for receiving air from various ducts 30, 32, 34, 36, 38, 40, 62 and 66, and extending vertically to a nozzle end 52. A plurality of first starboard bags 43 overlap a plurality of second starboard bags 44 in the horizontal direction and a plurality of first port bags 46 overlap a plurality of second port bags 47 in the horizontal direction. Also, the second starboard 44 and port 47 bags are spaced downstream from the first 43 starboard and port 46 bags. The nozzles 52 of the first starboard bags 43 are disposed in a first horizontal V.sub.a. -shape in relationship with the first port bags 46 to direct the emitting air in the emitting planes rearwardly and outwardly on each side of the aircraft 10 to move deicing material outwardly and rearwardly over the wings 12 and 14 and the nozzles 52 of the second starboard 44 and port 47 bags are disposed in a second horizontal V.sub.b -shape with each other to direct the emitting air in the emitting planes rearwardly and outwardly from the aircraft 10 to move deicing material outwardly and rearwardly over the wings from the first starboard 43 and port 46 bags. Three third starboard bags 45 are aligned horizontally with three third port bags 48 and downstream of the second starboard 44 and port 47 bags. A plurality of starboard 56 and port 58 are disposed close together for removing deicing material from the horizontal stabilizer of the aircraft.
摘要:
A system for de-icing aircraft in a de-icing area includes a first recessed storage area located substantially below ground level on a first side of the de-icing area. A first spraying boom, having at least one boom section, is used to apply de-icing solution to surfaces of aircraft. A first spray nozzle, for applying de-icing solution to surfaces of aircraft, is supported by the first spraying boom. The first spraying boom may be raised out of the first recessed storage area when an aircraft needs de-icing and lowered into the first recessed storage area for storage when aircraft de-icing is complete.
摘要:
A single nonfired heat source, such as a diesel engine, drives a hydraulic pump. The hydraulic pump in turn is coupled in a hydraulic circuit with a back-pressure valve which loads the hydraulic pump and hence the diesel engine. The engine also circulates a heat exchanging fluid, such as engine coolant through a second circuit. Water or engine coolant is circulated through the second circuit by means of a pump driven by the diesel engine. An exhaust gas heat exchanger coupled to the exhaust gases from the engine may also be included within the water coolant, the exhaust gases or both, and is then transferred to noncirculating deicing fluid in a storage tank. Heat developed within the hydraulic circuit which loads the engine is also transferred to the noncirculating fluid in the storage tank. The heated noncirculating fluid may be gently stirred to increase heat exchange efficiency and then either pumped directly to the utilization site from the storage tank or pumped in a single pass through a heat exchanger thermally coupled through the water coolant heat exchanger, hydraulic heat exchanger, or both, and thence to the utilization site.

The invention is a system for heating aircraft deicing fluid. The system is an aircraft deicer such as shown in FIG. 2 which includes an engine 210. The deicer systems comprises a tank 270 for holding deicing fluid. First pump means 250,252 and 254 are driven by engine 210 and pump deicing fluid from tank 270 through piping or conduit 266,264,230. Backpressure valve means 251,253,255 is positioned the outlet of the first pump means 250,252,254 respectively, to continuously, substantially and directly heat deicing fluid to a temperature sufficient to deice the aircraft.The system further comprises second pump means 212, 232 for directing deicing fluid through engine 210 to pick up heat rejected by engine 210. Once the deicing fluid has been pumped through engine 210, piping or a conduit means 216,222,228,230,266,264 connects the output of the second pump means 212,232 to the inlet of the first pump means 250,252 and 254.
摘要:
An apparatus for both de-icing and anti-icing an aircraft in one "pass". A pair of units are positioned above and below the aircraft. Each unit has respective nozzles oriented in one direction for dispensing de-icing fluid/air onto the aircraft as it approaches the units. Each unit further has respective nozzles oriented in an opposite direction for dispensing anti-icing fluid/air onto the aircraft as the aircraft moves away from the units. The apparatus is bi-directional so that the aircraft may approach the apparatus from either of two opposite directions. Means are provided for collecting and recycling the run-off of the de-icing and anti-icing fluids, respectively.
