Abstract

Fire fighting equipment e.g. for an airfield crash truck has a fire nozzle with a nozzle nose providing a jet or spray pattern for dealing with fire in an aircraft interior, the nozzle nose also being of a design sufficiently robust to enable it to break and be thrust through an aircraft window by fluid-pressure-operated piston-and-cylinder units or rams coupled thereto to generate the required impacting and penetrating force. The nozzle maybe carried on a universal mounting so that its attitude can be appropriately adjusted in use. <IMAGE>

Description

SPECIFICATION Improved fire-fighting equipment for airfield crash trucks This invention relates to fire-fighting equipment for use on airfield crash trucks.
In an airfield emergency, an aircraft fire must be tackled by the fire-fighting equipment with the absolute minimum of delay. If the fire is inside the aircraft directing water or foam jets on to the external skin of the aircraft is normally inadequate and access must be gained to the aircraft interior very quickly, especially as a flash-over fire can spread the whole length of the fuselage of even a large aircraft in 10 seconds or so. However, present-day large wide-bodied aircraft carrying up to 450 passengers have fuselages of materials and structual strengths that resist penetration.
According to the present invention, fire-fighting apparatus is provided comprising: a nozzle for connection to a supply of fire-controlling fluid with a nozzle nose robust enough to serve as an impacting bit to break through an aircraft window, and one or more fluid-pressure-operated pistonand-cylinder units or rams coupled to the nozzle to generate the impacting and penetrating force.
In the preferred form, the nozzle is orientatably mounted so that its attitude can be adjusted. Preferably the nozzle is mounted for universal angular movement about two axes at right-angles to one another, and piston-and-cylinder or ram means are provided to turn the nozzle about at least one of said axes.
Interchangeable nozzle noses may be available to give different jet or spray patterns and/or different impact pressures.
One embodiment of the invention will now be described by way of example with reference to the accompanying drawings, in which: Figure 1 is a plan view of the equipment, and Figure 2 is a side elevation.
The equipment has a horizontal mounting plate 11 on which are bolted a side-by-side pair of horizontally disposed pneumatic piston-and-cylinder units 12. Centrally between and parallel to the cylinders 12 there is disposed a fire-fighting nozzle 13 of generally tubular form that passes through and is welded to the centre of a laterally-extending yoke 14, the lateral ends of the yoke being provided with bosses 15 that are respectively connected to the piston rods 16 of the two cylinders 12. By this means, when the piston rods of the cylinders are extended in unison the nozzle 13 is thrust forward endwise by the yoke 14.
The back end of the nozzle 13 is fitted with an aluminium extension tube 17 for coupling to a hose supplying fire-fighting fluid to the nozzle. At its front end, the nozzle projects forward beyond the yoke 14 and terminates in a stainless steel impacting and spray jet nozzle nose 18.
The mounting plate 11 is carried on a swivel bearing assembly 19 which enables the nozzle and its operating cylinders to be rotated in a horizontal plane. The swivel bearing assembly 19 is itself carried on a base plate 20 which is in turn mounted by means of trunnion plates 22 on a transverse horizontal shaft 21 journalled in a pair of side bars of a horizontal boom 23. The axis of the shaft 21 is at rightangles to and intersects the axis of the bearing assembly. The nozzle 13 is therefore able to tilt fore and aft on the boom 23 about the shaft 21, which, together with the swivelling motion on the bearing assembly 19, gives the nozzle universal movement.Tilt-adjusting piston-and-cylinder units 24 are pivotally connected between brackets 25 at the rear of the base plate 20 and brackets 26 on a yoke 27 connecting the side bars of the boom 23, whereby operation of the cylinders adjusts the attitude of the nozzle 13 on the boom.
In use, the equipment is mounted on an elevating ladder of a crash truck and the nozzle 13 and cylinders 12 and 24 are connected, respectively, to the supply of water or other fire-fighting medium and the compressed air supply of the crash truck.
With the cylinders 12 retracted, the nozzle nose is placed close to an aircraft window 28 and the orientation of the nozzle can be adjusted by swivelling it on the bearing assembly 19 and by operation of the cylinders 24. The cylinders 12 are then actuated to extend the piston rods 16 and thereby break the window with the nozzle nose 18 and thrust the nozzle nose through as indicated in broken lines at 29. An air supply at, say, 100 psi provides sufficient energy to do this. At the same time, water or other fire-fighting medium is pumped to the nozzle and thereby discharged into the aircraft interior.
In addition to providing an impacting bit, the nozzle nose 18 directs the water or other fluid issuing from the nozzle upwardly and downwardly, as indicated at 30, within the aircraft cabin, thereby causing the water to be distributed in an effective manner for quenching the fire.
A particular feature is that the nozzle can be fitted with different types of impacting noses to suit customer requirements. The different nozzle noses are intechangeable to give different jet or spray patterns and/or, if desired, a nose taper for concentrating the impact force.
1. Fire-fighting apparatus, comprising a nozzle for connection to a supply of fire-controlling fluid with a nozzle nose robust enough to serve as an impacting bit to break through an aircraft window, and one or more fluid-pressure- operated pistonand-cylinder units or rams coupled to the nozzle to generate the impacting and penetrating force.
2. Apparatus according to Claim 1, wherein a number of interchangeable nozzle noses are provided to give different jet or spray patterns and/or different impact pressures.
3. Apparatus according to Claim 1 or Claim 2, wherein the nozzle is orientatably mounted so that its attitude can be adjusted.
4. Apparatus according to Claim 3, wherein the attitude of the nozzle can be changed in both horizontal and vertical planes.
