[0002] With the development of society, airplanes have become an increasingly common means of transportation for people's daily travel. However, airplane accidents have become more frequent. The impact of smoke generated in airplane accidents on passengers on the aircraft and the impact of smoke generated in different locations on passengers on the aircraft have become increasingly concerning. It is very necessary to conduct smoke circulation experiments on aircraft models.

[0003] The following are the commonly used experimental smokes:

[0004] 1. Oil basin combustion: The principle is to pour oil into a metal basin and then ignite it manually or electronically. The disadvantage is the unreliability of the artificial flame and the risk of leakage.

[0005] 2. Burning of smoke canisters or smoke cakes: The principle is that combustible materials containing smoke-generating substances produce thick smoke. Its disadvantages are that the amount of smoke is small and the duration is short, which cannot meet the smoke volume required in large aircraft simulation. Summary of the Invention

DETAILED DESCRIPTION

[0059] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0061] A smoke generator, the structure of which is shown in FIG. Figures 4 to 8, including a shell 201, a decomposer core 203, a core rod 205 and a main heating component 209.

[0062] In some embodiments, an insulation layer 202 is further provided on the inner side of the outer shell 201, and the insulation layer 202 surrounds an inner cavity with a roughly rectangular structure. The decomposer core 203 is installed in the inner cavity. The decomposer core 203 is used to install and fix the core rod 205. The decomposer core 203 is roughly a rectangular structure, and its length direction is consistent with the length direction of the inner cavity. The outer wall of the decomposer core 203 can fit tightly with the inner wall of the insulation layer 202 along the length direction of the inner cavity.

[0063] The decomposer core 203 is a hollow structure having a material inlet (not marked in the figure), a smoke outlet 213 and a cavity 204. The cavity is used to install a core rod and cooperate with the core rod to form a deflection channel. In some embodiments, the cavity can be a through hole that passes horizontally through the decomposer core, one port of the through hole serves as the smoke outlet 213, and the other port serves as an insertion port for the core rod 205. The smoke outlet extends axially along the cavity, and the material inlet is radially opened on the side wall of the decomposer core and is connected to the through hole.

[0064] The mandrel 205 is inserted into the cavity 204 of the decomposer core 203. The interior of the mandrel has an axially extending receiving cavity. The outer wall of the mandrel is provided with a groove 208, which bends and extends along the axial direction of the mandrel. In some embodiments, the mandrel comprises a main body 206, an operating portion 207, and a connecting portion 216. The main body and the operating portion are connected by the connecting portion. The groove 208 is provided in the main body 206. The main body is inserted into the cavity, and the operating portion is located outside the cavity. The mandrel is assembled and connected to the cavity via its connecting portion. The connection method can be threaded. By rotating the operating portion, the mandrel is fixedly installed in the cavity of the decomposer core.

[0065] The groove on the outer wall of the core rod cooperates with the cavity of the decomposer core to form a baffled channel. In some embodiments, the inner wall of the cavity mates with the top surface of the groove's sidewall, sealing the groove to form a baffled channel between the core rod and the cavity. This allows the oil-gas mixture to flow along the baffled channel as much as possible. The baffled channel extends in a baffled manner along the axis of the core rod. In a preferred embodiment, the baffled channel extends in a spiral shape. The inlet end of the baffled channel communicates with the material inlet of the decomposer core, and the outlet end communicates with the smoke outlet of the decomposer core.

[0066] The accommodating cavity extends sequentially in the operating portion, the connecting portion and the main body of the core rod 205. In some embodiments, the accommodating cavity is a blind hole with one end closed and the other end open, and the main heating component 209 is inserted into the accommodating cavity from its open end.

[0067] In some embodiments, the core rod 205 can be a sleeve structure with an open end and a closed end. The hollow cavity serves as the receiving chamber. The closed end serves as the head (second end) and penetrates the cavity. The open end serves as the first end and is located at the tail of the core rod. The main heating assembly 209 is inserted into the receiving chamber of the core rod 205 through the open end of the core rod. The material inlet is located near the first end of the core rod and extends radially through the side wall of the decomposer core. The smoke outlet is located near the second end of the core rod and extends axially along the cavity.

[0068] In some embodiments, the housing is further provided with a feed connector 210 and a smoke exhaust connector 212. The feed connector is used to connect to the material inlet of the decomposer core. The feed connector 210 passes through the housing and is inserted into the material inlet. The feed connector and the material inlet are sealed together. The feed connector is connected to the baffle channel through its outlet end, and a filter element 211 is provided at the outlet end of the feed connector. In some embodiments, the feed connector is an oil-gas tee, the first end of which is used to connect to the gas line, the second end is used to connect to the oil line, and the third end is used to connect to the baffle channel in the decomposer core. The oil-gas mixture is filtered by the filter element at the outlet of the third end and then enters the baffle channel.

[0069] The smoke exhaust connector 212 is used to connect to the smoke outlet 213 of the decomposer core. The smoke exhaust connector 212 penetrates the outer shell and the insulation layer and is inserted into the smoke outlet. The connection between the smoke exhaust connector and the smoke outlet is sealed. In some embodiments, the outer wall of the closed end of the core rod has a conical structure with a guide cone. The smoke exhaust connector has a tapered groove that matches the cone. The guide cone and the guide groove work together to guide the smoke more smoothly through the smoke exhaust connector and out of the smoke generator.

[0070] The main heating component 219 is inserted into the accommodating cavity of the core rod 205 and is used to heat and decompose the material flowing through the deflection channel to form smoke. In some embodiments, the heating component can use an electric heating tube, which is inserted into the accommodating cavity of the core rod and is externally powered.

[0071] In order to achieve better atomization and decomposition of the oil-gas mixture, some embodiments also include an auxiliary heating assembly (not shown in the figure). The decomposer core has a first mounting hole 214 for installing the auxiliary heating assembly, and the auxiliary heating assembly is plugged and installed in the first mounting hole. The auxiliary heating assembly can also use an electric heating tube, which is plugged into the first mounting hole and externally powered. The auxiliary heating assembly is used to cooperate with the main heating assembly in some situations to jointly heat the material flowing through the deflection channel. In some embodiments, the cavity is located at the center of the decomposer core, and the first mounting hole is set away from the center of the decomposer core.

[0072] In some embodiments, a sensor assembly (not shown) is further provided. The decomposer core has a second mounting hole 215 for mounting the sensor assembly. The sensor assembly is mounted within the second mounting hole of the decomposer core. The sensor assembly can be a temperature sensor, which can better monitor temperature changes within the smoke generator.

[0073] In some embodiments, the opening of the first mounting hole, the opening of the second mounting hole, and the opening of the cavity are all located on the same side of the resolver core, which facilitates assembly of the components.

[0074] A smoke generating system, see Figure 1 、 Figure 2 and Figure 3 , including a fuel tank 1, a smoke generator 2, oil and gas pipelines and corresponding control valves.

[0075] Fuel tank 1 is a conventional oil storage device used to store smoke oil for simulation tests. The smoke oil can be common smoke simulation oil, which is commercially available. The fuel tank has a refueling port 13, an air inlet and outlet (not shown), and an oil outlet (not shown). Smoke oil for the model test is added to the fuel tank 1 through refueling port 13.

[0076] The smoke generator 2 is the main place for the high-temperature decomposition and atomization of the smoke oil. In some embodiments, the structure of the smoke generator is as follows: Figures 4 to 8 The material inlet of the smoke generator is connected to the oil outlet of the oil tank 1 through the oil circuit 3. The oil circuit 3 is provided with a primary flow valve 9 and a secondary flow valve 10 in sequence to adjust the flow of smoke oil into the smoke generator 2.

[0077] The outlet of the first gas path 4 is connected to the gas path inlet and outlet of the fuel tank 1 for conveying inert gas into the fuel tank 1 to pressurize the smoke oil in the fuel tank 1 into the smoke generator 2. The gas path inlet and outlet also serve as an outlet for releasing pressure from the fuel tank.

[0078] The outlet of the second gas path 5 is connected to the material inlet of the smoke generator 2 and is used to deliver inert gas to the baffle channel of the smoke generator 2. A gas flow regulating valve 10 is provided on the second gas path to regulate the flow rate of the inert gas delivered to the smoke generator 2.

[0079] The inlet ends of the first gas path and the second gas path are both connected to the same inert gas source.

[0080] In some embodiments, the smoke generating system further includes a solenoid valve 8, to which the first gas path and the second gas path are both connected and controlled; when the solenoid valve is energized, it conducts in the forward direction, and the inert gas from the inert gas source enters the fuel tank and the smoke generator through the first gas path and the second gas path, respectively; when the solenoid valve is energized, it conducts in the reverse direction, and the air pressure in the fuel tank is released through the first gas path.

[0081] As an optional option for the solenoid valve, the solenoid valve can be a two-position three-way solenoid valve, the first end of which is an inert gas inlet, which is connected to an inert gas inlet pipe, which is connected to an inert gas source, the second end is a first inert gas outlet, the inlets of the first gas path and the second gas path are both connected to the first inert gas outlet, and the third end is a second inert gas outlet.

[0082] In some embodiments, the smoke generating system further includes a third air circuit, the inlet end of the third air circuit being connected to the third end of the two-position three-way solenoid valve and the outlet end being connected to the second air circuit; the third air circuit cooperates with the first air circuit to release the pressure in the fuel tank.

[0083] The first gas path, the second gas path, and the third gas path are all controlled by a two-position three-way solenoid valve. When the two-position three-way solenoid valve is energized, the first end (inert gas inlet) and the second end (first inert gas outlet) are normally open, and the third end (second inert gas outlet) is normally closed. Inert gas enters the fuel tank and the smoke generator through the first gas path and the second gas path, respectively. When the two-position three-way solenoid valve is de-energized, the first end (inert gas inlet) is normally closed, and the second end (first inert gas outlet) and the third end (second inert gas outlet) are normally closed. The pressure in the fuel tank is released through the first gas path and the third gas path, and the released pressure is then fed into the second gas path.

[0084] In some embodiments, a fourth gas circuit 7 is further included, the inlet end of the fourth gas circuit is connected to the inert gas inlet pipe, and the outlet end merges into the second gas circuit. A cleaning valve 12 is provided on the fourth gas circuit; the fourth gas circuit is independently controlled as a cleaning branch circuit.

[0085] In some embodiments, components such as the fuel tank 1, the smoke generator 2, the oil circuit 3, the first gas circuit 4, the second gas circuit 5, the third gas circuit 6, the fourth gas circuit 7, and the two-position three-way solenoid valve 8 are all encapsulated in a casing 18. An air inlet 20 and an electronic control board 19 are provided on the casing. The inert gas inlet pipe is connected to the inert gas source through the air inlet, and the inert gas source is delivered into the device through the air inlet. The heating component and the control parts of each regulating valve are integrated in the electronic control board 19, and the flow rate and heating temperature of each regulating valve are adjusted by the electronic control board.

[0086] In some embodiments, a smoke exhaust pipe 14 is arranged directly in front of the smoke exhaust connector of the smoke generator. One end of the smoke exhaust pipe is connected to the smoke exhaust connector of the smoke generator, and the other end extends to the outside of the casing. A heat radiation plate 15 and an auxiliary heating pipe 16 arranged close to the heat radiation plate are also arranged on the periphery of the smoke exhaust pipe. A smoke exhaust hood 17 is arranged on the top of the casing and above the smoke outlet of the smoke generator.

[0087] In some embodiments, the smoke is discharged through the smoke exhaust pipe 14, and the auxiliary heating pipe 16 does not need to be connected in this exhaust method; in some embodiments, if the smoke needs to be discharged upward, the smoke exhaust pipe is removed, and a sealing plate 21 is installed at the installation hole of the smoke exhaust pipe, and the auxiliary heating pipe is connected to make the air flow upward, so as to achieve the requirement of smoke being discharged upward through the smoke exhaust hood.

[0088] The principle of smoke generation Figure 1 :

[0089] After controlling the main heating assembly to reach the target temperature inside the smoke generator 2, an inert gas source is introduced. The inert gas is divided into two paths: one path, through the first gas path 4, presses the smoke oil out of the tank and into the smoke generator 2; the other path, through the second gas path 5, directly feeds the smoke generator 2. The smoke oil and inert gas meet at the smoke generator's material inlet and enter the baffle channel of the smoke generator 2. The main heating assembly heats the smoke generator, completing pyrolysis and atomization. The resulting smoke is then discharged through the smoke generator's smoke outlet and exhaust connection. The inert gas introduced into the smoke generator serves to prevent combustion of the smoke oil during the pyrolysis process and to enhance the stability of the smoke produced by the atomized smoke oil.

[0090] After the reaction is completed, the pressure in the fuel tank is released through the first gas path and the third gas path.

[0091] The smoke generator is cleaned through the fourth gas path before or after the reaction.

[0092] The first, second, and third gas lines are all controlled by two-position, three-way solenoid valves. When de-energized, the solenoid valves are in the down position, the inert gas inlet is normally closed, and the fuel tank and the fuel tank pressure quick-release line are normally open. When energized, the solenoid valves are in the up position, the inert gas inlet and the fuel tank gas inlet are normally open, and the fuel tank and the fuel tank pressure quick-release line are normally closed.

[0093] The air flow regulating valve and the oil flow regulating valve cooperate with each other to adjust the oil-air ratio fed into the smoke generator 2 .

[0094] The workflow under one implementation is as follows:

[0095] (1) After the main heating component is controlled to reach the target temperature in the smoke generator, the inert gas source is introduced into the device. If the target temperature in the smoke generator cannot be reached due to other reasons, such as low ambient temperature, current and voltage problems, the auxiliary heating component is turned on at the same time.

[0096] (2) Open the cleaning valve, blow the smoke generator clean, and then close the cleaning valve.

[0097] (3) The two-position three-way solenoid valve is powered on. One path of inert gas presses the smoke oil out of the tank and precisely controls it through the primary and secondary flow valves to achieve the target oil flow rate. The other path controls the gas flow rate through the gas flow control valve. The oil and gas paths meet at the oil-gas three-way valve and enter the smoke generator. The smoke is then heated in the spiral decomposition channel of the smoke generator, completing high-temperature decomposition and atomization. The smoke is then discharged horizontally through the exhaust pipe.

[0098] (4) If the smoke needs to be discharged upward, remove the exhaust pipe, install the sealing plate, and connect the auxiliary heating pipe to make the air flow upward so that the smoke can be discharged upward through the exhaust hood.

[0099] (5) After the experiment, all heating components are turned off, the two-position three-way solenoid valve is powered off, and the pressure in the tank is released through the tank pressure quick release pipeline.

[0100] (6) Open the cleaning valve, blow the smoke generator clean, and then close the cleaning valve.

[0101] (7) Turn off the power and gas supply.
