Description

Technical Field

[0001] This invention relates to the field of plasma ignition and combustion technology, and in particular to an embedded multifunctional plasma flame stabilizer. Background Technology

[0002] In high-speed gas flow combustion applications such as aerospace, gas turbines, and scramjet engines, flame stabilizers are key components primarily used to achieve fuel ignition and maintain continuous and stable combustion under high-speed inflow conditions. Traditional flame stabilizers (such as V-groove and evaporator tube stabilizers) mainly form a recirculation zone through mechanical structures, utilizing the high-temperature gas recirculation to heat the mixture, thereby achieving ignition and flame anchoring. However, these traditional devices are relatively simple in their ignition function, relying solely on an initial ignition source (such as an electric spark plug) to complete the ignition process. They lack active intervention and continuous excitation capabilities, resulting in poor ignition reliability, long ignition delay time, and insufficient combustion stability under harsh operating conditions such as low equivalence ratio, low temperature, low pressure, or high flow rate.

[0003] Especially in systems using liquid fuels (such as kerosene), fuel atomization quality directly affects combustion efficiency and ignition success rate. Traditional ignition methods struggle to effectively break up large liquid droplets, leading to incomplete fuel evaporation, uneven formation of the combustible mixture, and consequently limiting the expansion of the ignition boundary, or even causing ignition failure or flame quenching. Furthermore, traditional ignition devices are typically external, independently installed components (such as spark plugs or vortex stabilizers), with low integration with the flame stabilizer body. This not only occupies a large space but also limits the excitation range, making effective thermochemical control of the entire recirculation zone impossible, thus restricting their application prospects in compact combustion chambers.

[0004] In recent years, plasma-assisted combustion technology has attracted widespread attention due to its non-equilibrium characteristics, rapid response capability, and strong chemical reactivity. Among them, sliding arc discharge plasma, due to its ability to generate a large volume of non-equilibrium plasma under atmospheric pressure, accompanied by significant thermal effects and free radical generation capabilities, is considered a highly promising combustion enhancement method. Existing research attempts to place plasma generators within the combustion chamber to improve ignition performance. However, most schemes still adopt external or rear-mounted structures, failing to achieve integrated design with flame stabilizers, resulting in significant shortcomings in spatial adaptability, aerodynamic compatibility, and long-term operational reliability. Furthermore, existing plasma devices are mostly limited to instantaneous ignition assistance, lacking continuous excitation and active temperature rise control capabilities, making it difficult to maintain efficient and stable combustion across a wide range of operating conditions.

[0005] Therefore, there is an urgent need for a new type of flame stabilizer structure that can achieve a high degree of integration with plasma excitation function without changing the original aerodynamic shape and installation method. It should have the ability to continuously excite, discharge over a wide range, actively heat up and enhance atomization, thereby breaking through the functional limitations of traditional ignition methods and improving ignition reliability and combustion efficiency under complex working conditions. Summary of the Invention

[0006] The purpose of this invention is to provide an embedded multifunctional plasma flame stabilizer to solve the problems of low integration, single ignition function, limited excitation range, poor ignition reliability and insufficient combustion stability of traditional flame stabilizers under harsh conditions.

[0007] In a first aspect, the embedded multifunctional plasma flame stabilizer provided by the present invention includes: an evaporative flame stabilizer and an embedded exciter.

[0008] In conjunction with the first aspect, the present invention provides a first possible implementation of the first aspect, wherein the embedded actuator comprises: a ceramic housing, an anode, a cathode, and a plurality of metal sliding arc rails; The ceramic shell is installed on the inner side of the skirt plate, and the cathode, a plurality of the metal sliding arc rails and the anode are arranged in sequence at intervals and are respectively installed on the side of the ceramic shell facing the combustion zone.

[0009] In conjunction with the first possible implementation of the first aspect, the present invention provides a second possible implementation of the first aspect, wherein the ceramic housing is provided with embedded grooves respectively adapted to the cathode, a plurality of the metal sliding arc slide rails and the anode; The thickness of the cathode, the plurality of the metal sliding arc rails, and the anode is less than the depth of the corresponding embedded grooves.

[0010] In conjunction with the first possible implementation of the first aspect, the present invention provides a third possible implementation of the first aspect, wherein the cathode includes: a first extension and a second extension; The first extension extends along the x-direction perpendicular to the air intake direction, and the second extension is connected to one end of the first extension near the metal sliding arc rail and is inclined in a direction away from the metal sliding arc rail.

[0011] In conjunction with the third possible implementation of the first aspect, the present invention provides a fourth possible implementation of the first aspect, wherein the metal sliding arc slide rail includes: a straight portion, a first trapezoidal side portion, and a second trapezoidal side portion; The straight portion is parallel to the first extended portion, forming the main discharge channel; The straight portion is connected between the first trapezoidal side portion and the second trapezoidal side portion; The first trapezoidal side and the second trapezoidal side each form an angle greater than 90 degrees with the straight portion.

[0012] In conjunction with the fourth possible implementation of the first aspect, the present invention provides a fifth possible implementation of the first aspect, wherein the first trapezoidal side portion and the second trapezoidal side portion are connected to the straight portion at one end near the opening of the combustion region and extend into the combustion region respectively, forming a flared guide structure that facilitates the advancement of the sliding arc into the upstream airflow region.

[0013] In conjunction with the first aspect, the present invention provides a sixth possible implementation of the first aspect, wherein the embedded actuators are respectively mounted on the inner surfaces of the two opposing skirt panels; The two embedded actuators are triggered synchronously to generate plasma jets that propagate in the same direction.

[0014] In conjunction with the first aspect, the present invention provides a seventh possible implementation of the first aspect, wherein the evaporative flame stabilizer has a mixing chamber and a partition is installed between the mixing chamber and the combustion zone; The partition plate is provided with a plurality of dispersion holes, which are spaced apart, and at least some of the dispersion holes are located in a manner corresponding to the discharge initiation region of the embedded exciter.

[0016] In conjunction with the eighth possible implementation of the first aspect, the present invention provides a ninth possible implementation of the first aspect, wherein the evaporative flame stabilizer is equipped with an oil injection device, the oil injection device being inserted into the air inlet.

[0017] The embodiments of this invention bring the following beneficial effects: By directly integrating the embedded actuator onto the surface of the skirt of the evaporative flame stabilizer facing the combustion zone, the plasma excitation function and the flame stabilizer body are integrated into a single design. This structure significantly improves space utilization efficiency and system integration without altering the aerodynamic shape and installation method of traditional flame stabilizers, making it particularly suitable for compact combustion chamber environments with limited space. Due to the embedded actuator arrangement, its discharge area can precisely cover key locations in the combustion chamber recirculation zone, thereby overcoming the problems of limited excitation range, large aerodynamic interference, and low reliability of traditional external plasma devices, and enhancing the adaptability and long-term operational stability of the device under high-speed and high-temperature conditions.

[0018] This solution not only provides ignition assistance but also offers continuous excitation and active thermochemical regulation capabilities. The sliding arc discharge plasma generated by the embedded exciter can effectively generate a large number of active free radicals and release local heat under harsh conditions such as wide equivalence ratios, low temperatures, low pressures, and high flow rates, significantly enhancing the reactivity of the gas-fuel mixture, shortening the ignition delay time, and expanding the ignition boundary. Simultaneously, the strong electric field effect of the plasma helps improve the atomization quality of liquid fuel, promotes fuel evaporation and air mixing, forming a more uniform combustible mixture, thereby improving combustion efficiency and suppressing flame quenching. Therefore, this stabilizer combines multiple advantages, including enhanced ignition reliability, improved combustion stability, and expanded operating range, providing an innovative technical solution for efficient combustion under high-speed airflow conditions.

Detailed Implementation

[0023] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an embodiment of the present invention provides an embedded multifunctional plasma flame stabilizer, including an evaporative flame stabilizer 100 and an embedded actuator 200. The evaporative flame stabilizer 100 is a typical recirculation stabilizer structure, which is formed by two oppositely arranged skirts 110 enclosing a combustion zone 101. This combustion zone 101 is used to accommodate and maintain the flame anchoring zone under high-speed incoming flow conditions.

[0027] The key improvement lies in the fact that the embedded actuator 200 is directly mounted on the surface of the skirt 110 facing the combustion zone 101, that is, located in the critical recirculation zone inside the aerodynamic flow field. By integrating the plasma generation unit into the stabilizer body structure, the integrated design of functional components is achieved, significantly improving the system's space utilization and integration without changing the original flame stabilizer's external outline dimensions and mounting interface.

[0028] This integrated structure is particularly suitable for the compact combustion chamber environment of aerospace propulsion systems. It can achieve multiple functions such as ignition assistance, combustion enhancement and active thermochemical regulation in a limited space, overcoming the problems of large aerodynamic interference and limited excitation area caused by traditional external spark plugs or independent plasma devices.

[0029] like Figure 1 and Figure 4 As shown, the embedded actuator 200 includes a ceramic housing 210, a cathode 220, an anode 230, and several metal sliding arc rails 240.

[0030] The ceramic shell 210 is made of a highly insulating and high-temperature oxidation-resistant material (such as alumina ceramic or silicon nitride ceramic), and is fixed in the inner groove of the skirt plate 110, serving as electrical isolation and structural support. The cathode 220, multiple metal sliding arc rails 240 and the anode 230 are arranged sequentially at intervals along the air intake direction (x direction), and are all installed on the side surface of the ceramic shell 210 facing the combustion zone 101.

[0031] The aforementioned electrode structure constitutes the basic topological configuration of sliding arc discharge: when a high-voltage pulse power supply is applied between the cathode 220 and the anode 230, the initial arc first breaks down and forms between the anode and the nearest sliding rail; subsequently, under the dragging action of the high-speed incoming current, the arc moves downstream along each metal sliding arc rail 240, eventually reaching the cathode to complete one sliding discharge process. The non-equilibrium plasma generated in this process has abundant active particles (such as O, H, and OH free radicals), ultraviolet radiation, and local thermal effects, which can effectively promote fuel cracking, mixture activation, and combustion reaction acceleration.

[0032] Furthermore, the ceramic housing 210 is provided with multiple recessed grooves that match the shape of the electrodes, which are used to accommodate the cathode 220, each of the metal sliding arc rails 240 and the anode 230, respectively.

[0033] Preferably, the thickness of the cathode 220, the metal sliding arc rail 240, and the anode 230 is less than the depth of the corresponding embedded groove, so that the discharge working surface of each electrode is slightly lower than the surface of the ceramic shell 210, forming a "submerged" arrangement. This structural design has the following advantages: it effectively avoids the direct scouring of the electrode surface by high-speed airflow, reduces the electrode ablation rate, and improves the long-term operational reliability of the device; it reduces the aerodynamic resistance and disturbance of the plasma actuator to the mainstream gas, maintaining the good flow characteristics of the original flame stabilizer; and it provides an electrical protection barrier to prevent short-circuit failure caused by surface flashover, improving the insulation safety of the system.

[0034] In addition, the electrodes and ceramic substrates can be firmly connected by brazing or high-temperature bonding processes to ensure structural stability under complex working conditions such as vibration and thermal cycling.

[0035] Furthermore, the cathode 220 includes a first extension 221 and a second extension 222. The first extension 221 extends horizontally along the x-direction perpendicular to the main air intake direction, forming the main current induction region and the initial discharge initiation position. The second extension 222 is connected to one end of the first extension 221 near the metal sliding arc rail 240 and extends obliquely upstream (i.e., against the airflow direction). This oblique structure makes the anode end closer to the front end region of the incoming flow, which is beneficial for establishing an ionization channel earlier under low-speed or transient conditions, thereby enhancing the initial breakdown probability.

[0036] More importantly, this tilted structure can guide the plasma jet upstream of the combustion chamber during the arc initiation phase, thereby expanding the plasma's influence range, covering more unburned mixture areas, and improving the propagation efficiency of the ignition core. Experiments show that this structure can shorten the ignition delay time by more than 30%, especially under low temperature and low pressure conditions.

[0037] Furthermore, the metal sliding arc guide rail 240 includes a straight portion 241, a first trapezoidal side portion 242, and a second trapezoidal side portion 243. The straight portion 241 is arranged parallel to the first extension 221 of the aforementioned cathode 220, forming a stable main discharge channel to ensure smooth arc sliding on its surface. The first trapezoidal side portion 242 and the second trapezoidal side portion 243 are respectively connected to the two side edges of the straight portion 241, forming an angle greater than 90° (preferably 100° to 135°) with it, and the overall shape is an outwardly flared trapezoidal profile.

[0038] This structural design not only enhances the mechanical strength of the slide rail itself, but also reduces the local electric field concentration effect by increasing the edge curvature radius, suppressing abnormal discharges or edge arcing. Simultaneously, the trapezoidal structure helps guide the plasma plume to diffuse laterally, increasing the contact area between the plasma and the fuel-air mixture, and improving free radical generation efficiency and energy deposition uniformity.

[0039] In a further optimized manner, the first trapezoidal side portion 242 and the second trapezoidal side portion 243 are connected to the straight portion 241 at one end near the opening of the combustion zone 101, and extend as a whole toward the interior of the combustion chamber to form a flared guide structure.

[0040] This flared structure, under the combined effects of aerodynamics and electromagnetism, can effectively guide the sliding arc to partially propagate upstream after its generation, overcoming the limitation of traditional sliding arcs that only move downstream with the airflow. By adjusting the power supply parameters (such as voltage rise rate and repetition frequency) and matching the structural angle, partial countercurrent expansion of the plasma jet can be achieved, allowing it to cover the initial region of fuel injection, thus activating the droplet evaporation interface in advance and significantly improving atomization quality and mixing efficiency.

[0041] This characteristic is particularly important for applications using kerosene-based liquid fuels, as it allows for the efficient construction of a pre-combustion mixture before ignition, greatly expanding the ignition boundary.

[0042] See Figure 1 and Figure 2 Embedded actuators 200 are installed on the inner surfaces of the two opposing skirt plates 110. The two actuators are symmetrically arranged on both sides of the combustion zone 101 and achieve synchronous discharge through the same trigger control system.

[0043] The plasma jets generated by the two embedded actuators 200 propagate in the same direction (e.g., both towards the central axis of the combustion chamber or pointing towards the downstream flame core region), forming a synergistic excitation effect. This dual-sided excitation mode has the following advantages: significantly enhances plasma density and active species concentration, improving the overall combustion reaction rate; enables three-dimensional plasma distribution control, avoiding combustion asymmetry problems caused by single-sided excitation; and maintains stable ignition and combustion performance over a wide operating range, especially suitable for adaptive combustion control under variable Mach number flight conditions.

[0044] Synchronous control can achieve nanosecond-level precision triggering through FPGA or dedicated high-voltage drive module, ensuring the consistency of operation of the two sets of exciters.

[0045] Furthermore, the evaporative flame stabilizer 100 has a mixing chamber 102 inside, which is separated from the combustion zone 101 by a partition 120. The partition 120 has a plurality of dispersion holes arranged in an array at intervals to uniformly introduce the premixed gas from the mixing chamber 102 into the combustion zone 101.

[0046] Crucially, the location of at least some of the dispersion holes corresponds to the discharge initiation region of the embedded actuator 200 (especially near the anode). That is, when plasma is generated in the anode-rail region, it directly affects the nascent mixed gas flowing out of the adjacent dispersion holes.

[0047] This configuration allows plasma to pre-treat the gas mixture before it enters the main combustion zone, achieving: free radical injection to enhance the reactivity of the gas mixture; local temperature rise to promote the volatilization of light components and ignition preparation; and suppression of the risk of local flameout to improve flame stability margin.

[0048] Therefore, through precise structural coupling, a high degree of synergy between physical space and chemical reaction pathways is achieved.

[0049] like Figure 1 As shown, the evaporative flame stabilizer 100 is provided with an air inlet 130, through which external air or oxidizer enters the device. The mixing chamber 102 is located in the flow path between the air inlet 130 and the baffle 120, and is used to receive and initially mix the incoming airflow with fuel vapor. After fuel is injected from the fuel injection device 140, it is heated and evaporated in the mixing chamber 102 and fully mixed with the incoming air to form a homogeneous or near-homogeneous combustible mixture, which then enters the combustion zone 101 through the dispersion holes on the baffle 120 to participate in combustion.

[0050] This structure makes full use of the intake kinetic energy and thermal feedback mechanism to improve fuel evaporation efficiency. Combined with plasma excitation, it can complete high-quality ignition preparation in a very short time.

[0051] Finally, the evaporative flame stabilizer 100 also integrates a fuel injection device 140, which is inserted through the air inlet 130 and extends into the mixing chamber 102 to supply liquid fuel (such as aviation kerosene JP-8, RP-3, etc.) to the system.

[0052] Furthermore, the oil spraying device 140 can adopt pressure atomization, air-assisted atomization, or ultrasonic atomization, and the specific form can be selected according to the application scenario. Its outlet position is preferably close to the influence area of ​​the embedded exciter 200, so that the strong electric field, shock wave, and free radicals generated by the plasma can directly act on the ejected droplet group to achieve: electrostatic fragmentation effect: the strong electric field reduces the surface tension of the droplets, causing them to break into finer particles; plasma-assisted evaporation: local heating and free radical attack accelerate the phase change rate of the droplets; chemical ignition: microscale ignition nuclei are formed around the droplets, realizing a highly efficient combustion start-up process of simultaneous atomization and ignition.

[0053] In summary, this invention integrates the sliding arc plasma exciter into the evaporative flame stabilizer structure, achieving a multi-functional fusion of ignition, combustion stabilization, and fuel management. This overcomes the technical bottleneck of traditional stabilizers having limited functionality and poor adaptability, providing a reliable technical solution for cutting-edge fields such as hypersonic propulsion and low-emission combustion in gas turbines.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
