Description

Technical Field

[0001] The present invention relates to the field of solenoid valves, and in particular to a rapid actuation device for a projectile spoiler based on a solenoid valve. Background Art

[0002] The solenoid valve is an important fluid control unit, and its operating principle is based on the physical effect of electromagnetic fields on magnetic materials. The core components of the solenoid valve are the electromagnetic coil 6 and the valve core 7. When the solenoid valve is not energized, the valve core is usually held in the closed position by spring force or other mechanical devices, and the medium channel is blocked. When the power is turned on, the current generates a magnetic field inside the coil, penetrating the iron core and forming a strong magnetic field line path. The magnetic field attracts the movable valve core along the magnetic field path. When the core is in the closed state, the magnetic force causes the valve core to overcome the spring force or other resistance and move in the opening direction. The previously closed medium channel is opened, allowing the fluid to flow within the system or change the flow direction, thereby realizing the on / off control function of the solenoid valve.

[0003] A spoiler is typically installed inside the valve body 8 or at the outlet. Designed with a specific shape (such as serrations, orifice plates, or spiral guide grooves), it alters the flow direction and velocity distribution of the fluid or generates turbulence to achieve mixing, pressure reduction, noise reduction, or vortex prevention. The solenoid valve's workflow is as follows: solenoid valve energized → valve core actuated (opening / closing) → fluid passes through the spoiler → spoiler breaks up or guides the fluid → achieving the desired flow effect (such as homogenization or vibration reduction).

[0004] Traditional missile pneumatic control mostly uses hydraulic / pneumatic servos, which have the following problems: slow response speed (>15ms), which is difficult to adapt to the missile rolling above 30Hz; complex system (requires hydraulic pump / air tank), which occupies a large space on the missile body; insufficient overload resistance (<30,000g).

[0005] To address the above-mentioned problems, no effective solutions have been proposed so far. Summary of the Invention

[0006] The embodiment of the present invention provides a rapid actuation device for a projectile spoiler based on a solenoid valve, so as to at least solve the technical problem of slow response speed in the existing projectile startup control.

[0007] According to one aspect of an embodiment of the present invention, a rapid actuation device for a projectile spoiler based on an electromagnetic valve is provided, comprising: a solenoid valve, wherein an electromagnetic coil and a valve core are provided inside, wherein the electromagnetic coil generates current under voltage drive to generate axial tension; an angled slider, rigidly connected to the valve core, wherein the sliding contact surface of the slider is inclined at a preset angle and is treated with a diamond-like coating so that the friction coefficient is less than a preset friction coefficient threshold; a spoiler, made of a stainless steel spring sheet, with a preset pre-bent angle at the root to enhance elastic recovery ability; a protective shell, made of a steel plate, with a heat sink and an M2 threaded interface on the outer wall, and integrated with thermal conductive glue inside to fit the electromagnetic coil; wherein, when the solenoid valve is energized, the axial tension is converted into radial displacement through the angled slider, driving the spoiler to protrude into the airflow around the projectile, generating a shock wave to adjust the posture of the projectile; after the solenoid valve is de-energized, the spoiler is elastically reset by the spring sheet.

[0008] In some embodiments, the sliding contact surface of the bevel slider has an inclination angle of 15° to 45°, and the friction coefficient of the diamond-like coating is less than 0.1.

[0009] In some embodiments, the pre-bend angle of the spoiler is 3° to 8°, and the yield strength of the stainless steel spring sheet is ≥200 MPa.

[0010] In some embodiments, the protective shell further includes an electromagnetic shielding layer for isolating external electromagnetic interference and suppressing internal electromagnetic radiation.

[0011] In some embodiments, the transmission ratio between the angled slider and the spoiler is 1:1.5 to 1:3, so as to amplify the axial displacement into radial displacement.

[0012] In some embodiments, the heat sink of the protective housing and the electromagnetic coil are tightly fitted together via a high thermal conductivity colloid, and the thermal conductivity of the colloid is ≥5 W / m·K.

[0013] In some embodiments, the working mode of the solenoid valve includes single-pulse driving, and its instantaneous power handling capability is 5 to 10 times the rated power.

[0014] In some embodiments, when the spoiler penetrates into an airflow with a Mach number ≥ 2, a pressure difference generated at the end is ≥ 0.2 MPa.

[0015] In some embodiments, the device has an overload resistance of ≥30,000 g and an overall size of ≤Φ30 mm×60 mm.

[0016] In some embodiments, the driving circuit of the solenoid valve is configured in a dynamic thermal management mode to control the temperature rise by limiting the pulse width to ≤10ms.

[0017] In some embodiments, under the action of the magnetic field, the movable valve core of the solenoid valve is attracted, and the valve core is driven to move in the axial direction; through the axial movement of the valve core, the angled slider connected to it is pushed to slide in the inclined direction, generating a component force along the vertical direction of the spoiler; the component force is applied to the roots of the multiple spoilers in the form of spring sheets, so that the multiple spoilers are deformed and deflected to the target spoiler angle; in the deflected state of the spoilers, the high-speed fluid passing through the solenoid valve cavity is guided through the multiple spoilers to change the fluid flow direction or velocity distribution; based on the disturbing effect of the multiple spoilers on the fluid, a directional aerodynamic torque or turbulence effect is generated, which is used to control the posture of the projectile or improve the characteristics of the fluid system.

[0018] In an embodiment of the present invention, a rapid actuation device for a projectile spoiler based on a solenoid valve includes: a solenoid valve, which is internally provided with a solenoid coil and a valve core, wherein the solenoid coil generates current under voltage drive to generate axial tension; an angled slider, rigidly connected to the valve core, whose sliding contact surface is inclined at a preset angle and is treated with a diamond-like coating so that the friction coefficient is less than a preset friction coefficient threshold; a spoiler, made of a stainless steel spring sheet, with a preset pre-bent angle at the root to enhance elastic recovery capability; a protective shell, made of steel plate, with a heat sink and an M2 threaded interface on the outer wall, and integrated thermal conductive glue to fit the solenoid coil; wherein, when the solenoid valve is energized, the axial tension is converted into radial displacement through the angled slider, driving the spoiler to penetrate into the airflow around the projectile, generating a shock wave to adjust the projectile's posture; and when the solenoid valve is de-energized, the spoiler is elastically reset by the spring sheet. The above structure solves the technical problem of slow response speed in existing projectile startup control. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0029] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0030] The embodiment of the present invention provides a rapid actuation device for a projectile spoiler based on a solenoid valve, such as Figures 1 to 4 As shown, the device includes: a solenoid valve 4, an angled slider 1, a spoiler 2 and a white iron box shell 3.

[0031] The solenoid valve adopts model AH-0520B, with an internal coil resistance of 5.9Ω. When working, it provides a current of 3.33A at a voltage of 20V and can generate a pulling force of about 8N.

[0032] The bevel slider is made of titanium alloy (density 4.5g / cm 3), the sliding contact surface is designed with an inclination angle of 15° and is treated with diamond-like carbon (DLC) coating, with a friction coefficient of less than 0.1, effectively reducing movement friction.

[0033] The spoiler is made of 301 stainless steel spring sheet with a yield strength of 205 MPa. The root of the spoiler is pre-bent at 5° to enhance its elastic recovery and fatigue life (Nf>400 times).

[0034] The white iron box is made of high-strength steel and painted with corrosion-resistant white epoxy paint. Its functions include: mechanical protection: providing internal components with impact, dust, and moisture protection; electromagnetic shielding: effectively isolating external electromagnetic interference and suppressing electromagnetic radiation during operation of the solenoid valve; heat management: the iron box has a built-in heat sink structure that tightly adheres to the solenoid valve coil through thermally conductive adhesive to quickly dissipate heat; and mounting interface: the outer wall of the box is equipped with standard M2 threaded holes for quick fixing to the body structure.

[0035] When the solenoid valve is energized, the axial tension it generates is converted into radial displacement of the spoiler through the bevel slider, and the displacement transmission ratio is 1:2.14, that is, the axial displacement is converted into a larger radial displacement at the end of the spoiler.

[0036] After being driven, the spoiler penetrates into the supersonic airflow around the projectile, quickly forming a shock wave. The shock wave acts on the tail wing of the projectile, generating a pressure difference of at least 0.3MPa (under the condition of Mach number 2.5), thereby realizing rapid adjustment of the projectile's attitude.

[0037] After power failure, the spoiler quickly returns to its original position due to its own elasticity. The entire actuation process lasts about 6.2 milliseconds (using a 0.015-inch thick spring sheet and driven by a 20V voltage).

[0038] The working process of this device is as follows Figure 5 As shown, it can be divided into the following seven stages:

[0039] Step S502: power-on and current establishment phase (t=0-0.5ms).

[0040] The driver circuit applies a 20V step voltage to the coil at time t = 0. The coil current I(t) rises rapidly according to the inductance-resistance time constant τ = L / R, reaching the rated current of 3.33A in approximately 0.5ms. This creates a strong magnetic field around the coil, with a flux density B proportional to the current, meeting the required tensile force F = μ·N·I / R_eff.

[0041] Step S504, magnetic force action and iron core initial movement stage (t=0.5-1.0ms).

[0042] After the magnetic force Fmagnetic overcomes the initial friction and spring preload, it acts on the core, causing the core to begin axial displacement. The initial acceleration a≈Fmagnetic / m_core is about 10^4m / s 2 , so that the iron core moves about 0.3mm in 0.5ms, overcoming the internal friction and sliding of the solenoid valve.

[0043] Step S506, slider transmission stage (t=1.0-2.4ms).

[0044] A titanium alloy angled slider, rigidly connected to the core, follows the movement. Its 15° inclination converts axial kinetic energy into radial displacement: Δr = Δx / tan(15°). Dynamic analysis shows that a Δx of ≈ 1.5 mm corresponds to a radial extension of Δr of ≈ 3.3 mm at the end of the spoiler. The DLC coating has a friction coefficient of less than 0.1, resulting in extremely low frictional power consumption and no noticeable hysteresis during transmission.

[0045] Step S508: spoiler insertion and shock wave formation stage (t=2.4-3.0 ms).

[0046] The spoiler cuts into the supersonic airflow at a relative velocity of M = 2.5, generating a local shock wave structure. The shock wave angle θ ≈ arcsin (1 / M) ≈ 23.6°. The shock wave forms a high-pressure region at the root of the blade, generating ΔP ≥ 0.3 MPa.

[0047] Step S510, posture control torque output stage (t=3.0-4.0ms).

[0048] High pressure area pressure F_out=△P·A spoiler (A≈2mm 2 The resulting lateral force passes through the center of the projectile, generating a control torque τ = F_out·d (d ≈ 5 mm). The projectile achieves the desired roll correction (approximately 1 / 4 turn) in just 1 ms.

[0049] Step S512: power off and magnetic field decay stage (t=4.0-4.6 ms).

[0050] The drive circuit is disconnected from power at t≈4.0ms. The coil current begins to decay naturally along the inductor-resistor network, and the induced voltage is absorbed by the diode circuit. The magnetic field decay time constant, τ_decay≈L / R, remains constant. When the coil current drops from 3.33A to 0, the reverse magnetic force generated is insufficient to maintain core displacement.

[0051] Step S514, elastic reset and recovery phase (t=4.6-6.2ms).

[0052] The spoiler's built-in spring uses its elastic potential energy to rapidly rebound the trigger, restoring a displacement of approximately 3.3mm. The average recovery acceleration a_rec ≈ σ·E / ρ (σ is stress, E is elastic modulus), ensuring full reset within 1.6ms. The slider and core also return to their initial locked position within the same timeframe, resulting in a total actuation and recovery cycle of approximately 6.2ms.

[0053] In the embodiment of the present application, the inclined surface of the slider is coated with DLC (friction coefficient <0.1); the root of the spring leaf is pre-bent 5° to improve fatigue life (Nf>400 times); and the solenoid valve winding is impregnated with nano-alumina thermal conductive adhesive (thermal conductivity coefficient 8W / m·K).

[0054] In the present invention, the solenoid valve (AH-0520B type) drives the spring steel sheet through an angled slider (45° inclination) and adopts a dynamic thermal management solution with a 6ms pulse width limit (corresponding to a maximum rolling frequency of 42Hz).

[0055] The embodiments of the present invention have the following beneficial effects: 1) ultra-fast response: the measured rise time is 2.4ms (when driven at 20V); 2) high overload resistance, and it functions normally after passing the 36,000g impact test; 3) compact structure: the overall size is ≤Φ25mm×50mm (including the solenoid valve, slider, and spring leaf); 4) energy consumption optimization: the single-pulse mode can withstand 250W of instantaneous power (10 times the rated value).

[0056] This embodiment of the present application also provides another solenoid-valve-based rapid actuation device for a projectile spoiler. This differs from the aforementioned device in that it utilizes a 0.028-inch spring plate driven by 30V, resulting in a shorter rise time of 1.7ms and a reduced maximum actuation count of 12. A thermal fuse (triggered at 72°C) replaces forced heat dissipation. Furthermore, the angled slider is eliminated, with the solenoid valve directly pulling the spring plate, extending the response time to 11ms.

[0057] Specifically, a 0.028-inch-thick 301 stainless steel spring leaf is used, achieving an increased yield strength of 220 MPa and a higher elastic modulus. The multi-stage pre-bend at the root of the spring leaf is replaced with a single sharp bend (8°). Finite element simulation is used to optimize the bend radius, shifting stress concentration to a non-fatigue-sensitive area. This design sacrifices some fatigue life (reducing the maximum number of actuations to 12) but significantly improves rigidity and reduces deformation hysteresis.

[0058] The drive voltage is increased to 30V, and the solenoid valve coil adopts a low-inductance winding design (inductance reduced by 40%), combined with a low-resistance wire (resistance of 4.2Ω), achieving a peak current of 7.14A and a magnetic field strength 2.1 times that of the previous embodiment. To suppress current overshoot, a transient voltage suppressor (TVS) diode is connected in series in the circuit, and pulse width modulation (PWM) technology is used to precisely control the power-on time.

[0059] The angled slider in the previous embodiment is eliminated, and the solenoid valve core is directly connected to the spring plate via a rigid coupling. The coupling is made of titanium alloy, and the contact surface is designed as a hemispherical projection-groove coupling structure, which reduces transmission backlash through the principle of geometric self-locking. The coupling surface is deposited with a titanium nitride (TiN) coating with a hardness of HV2000 and a friction coefficient of less than 0.08.

[0060] A bimetallic thermal fuse (triggered at 72°C) replaces the forced heat dissipation system in the previous embodiment. The thermal fuse is integrated near the solenoid valve coil and tightly bonded to the coil via thermally conductive silicone. When the coil temperature exceeds the threshold, the fuse automatically cuts off the circuit to prevent overheating damage. Furthermore, the housing features an array of 0.5mm diameter radiant heat dissipation holes, with spacing optimized through CFD simulation to balance heat dissipation efficiency and dust protection.

[0061] The working process of the device is described below. Figure 6 As shown, the process includes the following steps:

[0062] Step S602: establishing high voltage pulse driving and magnetic field transient.

[0063] The external control system sends a 30V pulse signal, the TVS diode suppresses the voltage spike, and the PWM module locks the pulse width to 4ms (corresponding to a maximum actuation frequency of 250Hz). The solenoid valve coil current rises to 7.14A within 0.3ms, and the magnetic field strength instantly reaches 1.8T. Due to the low-inductance winding design, the magnetic field buildup time is shortened by 60% compared to Example 1. The coil uses a double-helix winding process, with the inner and outer windings wound in opposite directions to offset the eddy current effect and ensure a uniform magnetic field distribution.

[0064] Step S604: direct drive of the valve core and rigid transmission of the spring sheet.

[0065] The valve core is accelerated by 1.2×10 4 m / s 2 Axial movement directly pulls the spring leaf through the titanium alloy coupling. The coupling's hemispherical projection engages the groove at the base of the spring leaf, achieving zero-backlash transmission. The spring leaf undergoes radial displacement under tension, with the end displacement Δr approximately 4.2mm. The elimination of the angled slider shortens the transmission path and reduces mechanical energy loss. However, the high-frequency impact on the contact surface between the coupling and the spring leaf requires the high wear resistance of the TiN coating to mitigate this.

[0066] Step S606: Ultra-high-speed spoiler insertion and shock wave enhancement.

[0067] The spring blade penetrates the supersonic airflow at a faster speed, its tip designed as a sharp wedge. The shock wave angle is reduced by 15% compared to Example 1, increasing the shock wave intensity and creating a 0.45 MPa pressure differential at the tail flap of the missile. The key to this improvement lies in the dynamic airflow coupling algorithm: by monitoring the missile's attitude feedback signal in real time, the spoiler insertion depth is dynamically adjusted to ensure precise alignment of the shock wave position with the flap's pressure center.

[0068] Step S608: thermal fuse protection and energy dissipation.

[0069] After the 4ms pulse ends, the coil temperature rises rapidly due to Joule heating. The thermal fuse monitors the temperature in real time using a bimetallic deformation sensor. When it reaches 72°C, the fuse contacts separate, completely severing the circuit. Simultaneously, the radiant heat dissipation holes utilize high-speed airflow to create a negative pressure suction effect, dissipating internal heat through the hole array. While this passive cooling solution cannot continuously suppress temperature rise, it can prevent permanent damage from a single overload through the fusing mechanism.

[0070] Step S610: elastic reset of the spring piece and status feedback.

[0071] After power is removed, the spring sheet quickly rebounds thanks to its high rigidity. Thanks to the single-point sharp-angle bend design, the reset acceleration is increased to 1.5 times that of Example 1, and the reset time is shortened to 1.2ms. To monitor the reset status, the system embeds a micro-MEMS accelerometer at the base of the spring sheet, whose signal is transmitted to the control system in real time via a wireless radio frequency (RFID) module. If an incomplete reset is detected, the system automatically extends the interval between the next drive pulse to avoid cumulative errors.

[0072] Under a 55,000g launch overload, the shell's radiant heat dissipation holes double as micro-damping pressure relief channels. As the overload shock wave passes through the hole array, some of the energy is dissipated by turbulent flow through the hole walls, while the remaining energy is absorbed by the gradient density aluminum foam layer within the shell. This aluminum foam's density gradually increases from the outside inward, achieving a stepped attenuation of impact energy through gradient compression, ensuring that the peak stress on internal components remains below the design threshold.

[0073] The embodiments of this application offer the following benefits: 1) Extremely fast response: High-voltage drive and simplified transmission paths achieve a 1.7ms rise time, meeting the requirements for ultra-high-frequency attitude correction. 2) Optimized overload resistance: Gradient aluminum foam and heat dissipation hole pressure relief design maintain functional integrity under extreme overloads. 3) Thermal safety redundancy: Bimetallic fuses and passive heat dissipation work together to mitigate the risk of transient overheating. 4) Intelligent feedback: MEMS sensors and RFID technology enable non-invasive status monitoring, improving system reliability.

[0074] The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
