6 Claims. (Cl. 169-2) The present invention relates to improvements in airplane runways and more particularly to airplane runways provided with self-contained fire extingu-ishing apparatus.
Objects and advantages of the invention will be obvious herefrom, or may be learned by practice with the invention, the same being realized and attained by means of the instrumentalities and combinations pointed out in the appended claims.
lHeretofore in the event that a disabled aircraft posed the threat of fire upon landing, it was necessary before clearing such aircraft for landing to spread carbon dioxide foam or other suitable fire extinguishin-g materials on the runway. This foam Was generally spread from trucks :through pressure hoses and was necessarily time consuming, often requiring considerable delay in landing of such disabled aircraft. Further, this arrangement required a certain amount of forewarning of the impending perilous situation in order to eifect the spreading of the fire extinguishing material on `the runway.
The present invention is characterized by the provision of a plurality of spaced pressurized fire extinguishing units positioned beneath the runway. The units are provided with electrically responsive valves operable preferably from a common control system to effect either simultaneous or selective release of the fire extinguishing material upwardly 4through apertures in the runway, the units being spaced to provide complete coverage of the runway. In such an arrangement the iire extinguishing material can be released immediately prior to the landing of a disabled aircraft without delay thereof. Likewise, in the event circumstances arose, Without prior warning, which require instant application of fire extinguishing material, the control system preferably operative from a central control location; such as, the flight control tower, can be actuated to effect immediate application of the re extinguishing medium at the desired location.
it is therefore an object of the present invention to provide a novel aircraft runway having a plurality of pressurized fire extinguishing units positioned below the upper level of the runway for effecting dispersion of the fire extinguishing medium onto said runway.
It is another object of the present invention to provide a novel aircraft runway having a plurality of pressurized fire extinguishing units and a control system for said units selectively actuating a predetermined number of said units.
It is likewise an object of this invention to provide, in an `airplane runway, a plurality of spaced excavations each accommodating a pressurized fire extinguishing unit and a control system for selectively actuating said units.
Another object of the preesnt invention is to provide an airplane runway having a plurality of spaced apertures therethrough, `a manhole associated with each of said apertures Vand a pressurized -re extinguishing unit accommodated in each manhole with the nozzle thereof directing the ow from the unit upwardly of the runway surface.
The invention consists in the novel par-ts, constructions, arrangements, combinations and improvements herein shown and described.
The accompanying drawings, referred to herein and constituting a part hereof, illustrate one embodiment of the invention and together with the description, serve to explain the principles of the invention.
FIGURE l is a plan view of an airport having a pair of airplane runways provided with the present invention.
FIGURE 2 is a side elevation, partly in section, illustrating a portion of the present invention in operative position.
FIGURE 3 is a schematic wiring diagram of a suitable control system for the present invention.
Referring to the drawings, FIGURE l illustrates an airport having a pair of airplane runways 10 and 12 divided for convenient reference into areas A, B, C, D, respectively. The runways 10 and 12 are interconnected by suitable taxi strips 14 and 16 and include a control tower section, generally -designated T. Each runway 10 and 12 includes a landing apron 18 preferably of concrete, bituminous asphalt, macadam, or other hard surface. Each apron 18 is provided with a plurality of excavated sections 2G, accommodating a preferably circular manhole 22. Manhole 22 may be formed of brick or steel, but is preferably of concrete as shown in FIGURE 2. A Icover plate or grating 24, preferably of steel, is positioned over manhole 22 and Hush with the upper surface of apron 18. Manholes 22 may be formed when runways 10 and 12 are being constructed, or manholes 22 may be `formed therein in existing runways.
In .each manhole 22 is positioned a pressurized iire extinguishing unit 26. Unit 26 may be a conventional carbon dioxide pressurized cylinder such as is commercially available from Walter Kidde and Co., Belleville, New Jersey. Each pressurized unit 26 is provided with a discharge head 28 which is, in turn, provided preferably with a swivel adapter 32 and is operatively connected to a discharge nozzle 34 positioned in open-ing 25 in grating 24 and oriented for upward dispersion of the fire extinguishing medium from unit 26. The spacing of manholes 22 is determined by the range of their associated units 26. Manholes 22 are spaced so far apart as possible while still permitting units 26 to effect substantially complete coverages of re extinguishing medium on runways 10 and 1.2.
Each head 2S is individually controlled by a solenoid 30. Solenoids 30 are, in turn, interconnected in four operating circuits 36, 33, 40, and 42 for effecting discharge of the fire extinguishing medium from units 26. Circuits 36, 38, 4?, and 42 are each associated with a separate area A,B, C or D and each include separate normally-open switches 44, 46, 4% and 5G. Likewise, each circuit S6-42 is interconnected to a common element 52; such as a pushbutton.
ln operation, each pressurized unit 26l is positioned in its manhole 22 with the nozzle 34 thereof disposed in opening as shown in FlGURE 2. When it is necessary to release re extinguishing medium onto runway 10 or 12, an operator in control tower T presses one or more of the switches i4-5i), each of which associated with area A, B, C, or D, respectively. Clo-sing its associated switch #i4-50 completes one of the 36-42 circuits energizing the solenoids 30 associated therewith. Upon actuation, solenoid 3i) releases the normally closed valve (not shown) of discharge head 28, effecting immediate release of the pressurized re extinguishing medium from unit 26.
In the event it becomes necessary to release such medium over the entire run- Ways 10 and 12 simultaneously, pushbutton control 52' is depressed which immediately energizes each of the circuits 36-42, releasing the fire extinguishing medium over the entire runways 1) and 12 at once.
lt should should be understood that the above description has been made with reference to the preferred ernbodiment illustrated in the drawings and that modifications and alterations can be made therein without departing from the'invent-ion, except as expressly limited hereinafter in the claims;
