Definitions

  • the invention relates to apparatus for controlling against fire, in other words extinguishers.
  • the invention finds its application in stationary fire suppression devices that can be triggered remotely.
  • the invention relates more particularly to the generation of an inert gas by combustion of a pyrotechnic composition and the diffusion of this gas in the fire zone with controlled flow; the invention refers to a fire extinguisher including an enclosure of combustion, a regulation system and means of diffusion in the fire zone, in particular used in the field of aeronautics.
  • the devices extinguishing media include a tank containing a extinguishing agent that is diffused on the fire zone to extinguish it, but also to prevent its extension.
  • Agent tank extinguishers are classified into two broad categories.
  • the first one category concerns permanent pressure vessels in which a gas provides the pressurization permanent agent within a single bottle serving as a reservoir.
  • the extinguishing agent is released by a valve, at the outlet of said bottle.
  • a propellant is released only putting the fire extinguisher into service and propelling the agent extinguisher which is not stored under pressure.
  • extinguishers currently used to extinguish an engine fire aircraft. These devices use halon as extinguishing agent, stored in liquid form as a result of level of pressurization of the bottle used as tank. Depending on the security requirements, two extinguishers or more can be installed. One or several distribution pipelines connected to each bottle allow the distribution of the agent towards the area or areas to be protected. At the end bottom of the bottle, a calibrated lid allows to close the distribution pipe for keep the halon in the bottle. A sensor of pressure is also installed in order to check, continuous way, the pressurization of the bottle.
  • a pyrotechnic detonator When a fire is detected, a pyrotechnic detonator is triggered: the shock wave generated by this detonator comes to pierce the shutter optic, which causes the emptying of the bottle and the evacuation of the extinguishing agent under the effect of pressure towards the areas to be protected via distribution pipelines.
  • fire extinguishers With regard to fire extinguishers second category they use a separate device pressurizing. These devices fight against fire are usually equipped with a first compressed gas tank and a second tank for the extinguishing agent. When the device is used, the gas contained in the first tank is put into communication through an orifice with the second reservoir, which allows the pressurization of the bottle containing the extinguishing agent. Sometimes the first compressed gas tank is replaced by a gas generator as described in the document WO 98/02211. In any case, when the agent extinguisher is pressurized, it is ejected from second class fire extinguishers to fight the fire, as for the appliances of the first category.
  • the object of the invention is to remedy mentioned drawbacks of fire extinguishers, in particular for fires in aircraft engines, among others advantages.

  • the device according to the invention comprises therefore a pyrotechnic gas generator associated with means for distributing the gas generated as an agent fire extinguisher and means to regulate the pressure.
  • the generator of gas comprises an enclosure comprising a block of propellant and a pyrotechnic igniter.
  • the ignition of the pyrotechnic igniter by electric current allows for example the start of the combustion of the propellant whose decomposition allows the generation an inert gas.
  • the extinguishing device includes filters located in the enclosure of combustion or in the means of distribution, so that soot and ash also produced by the combustion of the pyrotechnic composition do not reach not the fire zone.
  • the device comprises means for cooling the generated gas.
  • the extinguishing device may comprise a variable number of gas generators, which are connected to the same distribution means. It is also possible to have multiple materials pyrotechnics of different compositions in a even pregnant.
  • the regulation means are parameterized way by determining the pressure at which the inert gas is expelled from the enclosure, directly related to the flow of gas ejected on the zone fire and concentration, oxygen or other component, sought in the areas to be treated. next the geometry of the distribution network, the dimensions and the breakdown of the areas to be treated, taking account the pressure losses or the layout of the zones to treat, those skilled in the art can determine the pressure required. These calculations can be refined during experimentation.
  • the means of pressure regulation consist of at least one control valve located in the means of distribution, the opening of which is ordered during the extinguisher trigger sequence, either by an external order, either by putting into the combustion chamber.
  • the control valve is advantageously controlled according to a given law and defined by the user, possibly using information from sensors, which measure for example the concentration of oxygen in the zones treat ; this allows loop regulation closed, even finer, the pressure of the gas.
  • the opening of the valve can be controlled remotely, by manual control, or by a mechanism control coupled to the firing means of the pyrotechnic composition.
  • the geometry of the block of material pyrotechnics also makes it possible to generate combustion according to a predetermined law.
  • the means of may also, or alternatively, consist of a determination of the different parameters of the gas generator, and in particular the geometry of the propellant block, which ensures controlled generation of inert gas injected into the areas to be protected.
  • control valve through a calibrated orifice: a once triggered, burning the block of material pyrotechnics no longer requires a command, and the calibrated orifice makes it possible to control the pressure at which will be the combustion of the propellant so as to ensure the agent flow required for inert gas from the fire zones.
  • Regulation can also, alternatively or in addition, be provided by other regulating devices such as a regulator whether or not associated with a device that creates a difference pressure (diaphragm, nozzle).
  • the extinguisher can be triggered by a remote operator. he can also be put into operation directly by a ignition device receiving the information of a sensor that detects conditions related to the probability of a fire. To avoid triggers unwanted, especially during operations maintenance, the device can be equipped with neutralization.

It is desirable that the generated gas is inert, but also that it is not not polluting or corrosive, especially in the context of a fire zone 6 located in an aircraft engine. In this respect, the gas generated therefore comprises a part of nitrogen, at less 20% or even 40%, obtained by the combustion of a pyrotechnic composition strongly "nitrogenated"; he is also possible to associate nitrogen for example with carbon dioxide to increase concentration in neutral gas injected and reach the desired thresholds.
  • the means of regulating the pressure make it possible to obtain a predetermined profile of the oxygen concentration in the fire zone, as a bearing for a non-zero time period, or a profile in crenels; it is clear that each of concentrations can have a margin of error per relative to the theoretical fixed value of the bearing.
