Description

Technical Field

[0001] This invention belongs to the field of pyrotechnics technology, specifically relating to an ultra-insensitive electrically controlled pyrotechnic and its actuation system. Background Technology

[0002] Pyrotechnics, as the heart of weapon systems, are the first point of impact for all types of weapons from launch to destruction. Current pyrotechnic technology remains largely mechanically driven, delivering energy directly in a single burst, which is insufficient to meet the demands of intelligent weapons in future battlefield environments. Pyrotechnics are rapidly evolving towards insensitive, high-energy, and intelligent designs, as well as achieving directional and precise detonation. Fifth-generation pyrotechnics are integrated products or arrays based on digital pyrotechnic principles, possessing precisely controllable energy. These include MEMS pyrotechnics, SMART pyrotechnics, and digital pyrotechnics, which are intelligent pyrotechnics manufactured using microelectromechanical integration (MEMS) by embedding information within the pyrotechnics.

[0003] Currently, intelligent pyrotechnics are still largely in the exploratory stage, as traditional pyrotechnic agents are insufficient for precise energy release control. Energy output levels must be achieved through dosage adjustments or complex structural designs, reducing the reliability of pyrotechnic components and hindering product finalization. Intelligent pyrotechnics with higher efficiency and precision require intelligent and controllable pyrotechnic agents to achieve optimal energy release. Electrically controlled pyrotechnic agents can output large-area high-temperature pulsed plasma shock waves in response to electrical signals, bombarding downstream charges. This eliminates the need for multi-stage initiation and detonation sequences, enabling in-line ignition and detonation of the main charge. Furthermore, the real-time programmable energy release method of electrically controlled intelligent pyrotechnics provides more development avenues and possibilities for fifth-generation intelligent pyrotechnic technology.

[0004] On the other hand, insensitive munition technology is a research hotspot in the weapon systems of major military powers today. Pyrotechnics, as the initial working element for ignition and detonation, are the most dangerous and sensitive link in various equipment systems; their safety and reliability directly affect the overall system effectiveness. Electrically controlled pyrotechnics cannot be ignited by open flames, bullet fire, strong electromagnetic interference, or extreme mechanical environments, possessing ultra-insensitive characteristics. Therefore, intelligent pyrotechnics based on electrically controlled pyrotechnics have great application potential in inline solid rocket motor ignition and insensitive munition detonation systems. Summary of the Invention

[0005] The purpose of this invention is to provide an ultra-insensitive electrically controlled pyrotechnic device and its actuation system, which can realize intelligent and controllable energy release, actuation output and ultra-insensitive characteristics of the pyrotechnic device, can realize synchronous detonation of the main charge, realize maximum energy output of the main warhead of conventional weapons and implosion detonation of nuclear weapons; the electrically controlled pyrotechnic device actuation system can realize partial azimuth detonation of the main charge, and realize the explosive cutting and separation of some components of rocket / aircraft combat units.

[0006] The technical solution to achieve the purpose of this invention is: an ultra-insensitive electrically controlled pyrotechnic device, including a supercapacitor, a logic chip, a time delay relay module, an eight-axis electrically controlled pulsed plasma generator, an eight-bridge negative electrode plate, an eight-bridge positive electrode plate, an eight-axis substrate nest, a positive electrode pin, a negative electrode pin, an embedded TTL level externally controlled high-level bridge film, and an embedded TTL level externally controlled low-level bridge film.

[0007] The logic chip output array pins are connected to the beginning of the embedded TTL level externally controlled high-level bridge membrane and the embedded TTL level externally controlled low-level bridge membrane in parallel inside the eight-axis base nested body. The output terminals of the embedded TTL level externally controlled high-level bridge membrane and the embedded TTL level externally controlled low-level bridge membrane are connected to the communication pins of the time delay relay module fixed at the slot on the outside of the eight-axis base nested body to form a TTL level communication grid, thereby controlling the opening and closing of the relay module in the high-voltage circuit.

[0008] The capacitors power the array of capacitors. The number of capacitors connected to the circuit is determined by the logic chip, thereby changing the voltage input to the electronically controlled pulsed plasma generator and generating high-temperature pulsed plasma waves of different densities to bombard and detonate the lower main charge.

[0009] Furthermore, the pins on the upper part of the eight-axis substrate are fixed and bonded to the logic chip using a wave soldering-SMT combined method. The logic chip controls the TTL level orientation output through autonomous command decision based on the command signal source.

[0010] The logic chip controls the opening and closing of time-delay relays in all directions through the TTL level communication grid;

[0011] The relay circuit input pin is connected in series with the relay, and the relay circuit output pin is connected in series with the eight-bridge positive electrode plate located on the outer ring of the logic chip. The positive electrode plate is connected to the positive terminal of the electronically controlled pulsed plasma generator through a metal wire.

[0012] The negative terminal of the electronically controlled pulsed plasma generator is connected to the main circuit via an eight-bridge negative electrode plate.

[0013] The positive and negative electrode plates are bonded to the nested body and are distributed in a ring.

[0014] Furthermore, a 0.5mm air gap is left between the positive electrode plate and the negative electrode plate to prevent electrical breakdown;

[0015] The material of the eight-axis base nest is either an alumina ceramic circuit board or a PCB board.

[0016] Furthermore, the positive and negative electrode plates are connected to the positive and negative output terminals of the supercapacitor respectively through positive and negative electrode pins penetrating the nested body. The capacitor is connected to the bottom of the nested body by threads, and the two are coaxial.

[0017] The supercapacitor supplies power only to the main circuit, while the logic chip is in self-powered mode and has a self-destruct function. The chip self-destructs after the signal detection source receives the correct key.

[0018] Furthermore, the electrically controlled pulsed plasma generator includes an insulating electrode plug, an electrode rod, a main body constraint tube, and a convergence terminal;

[0019] The electronically controlled pulsed plasma generator is distributed in eight directions, with the convergent output end facing outwards to achieve power output and energy release, and is embedded in the nested body.

[0020] Furthermore, the two ends of the main constraint tube are respectively an insulating electrode plug and a convergence terminal, and both the electrode plug and the convergence terminal are fixed to the main constraint tube by threads.

[0021] Furthermore, the insulating electrode plug is made of ceramic or PTFE; the main constraint tube is made of 304 or 316 stainless steel.

[0022] The convergence terminal is made of carbon fiber wound wire, with an inner layer coated with tungsten copper as a backing.

[0023] Furthermore, the electrode rod is coaxially fixed to the center of the main constraint tube, and the electrically controlled pyrotechnic agent is located in the annular space between the electrode rod and the constraint tube. The two serve as the positive and negative electrodes for the electrically controlled pyrotechnic agent to be activated and connected to the main circuit.

[0024] Furthermore, the electrically controlled pyrotechnic agent is one or two of the following: an energetic oxidant-polymer electrolyte-high calorific value metal powder and an energetic oxidant-polymer electrolyte-carbonitride fiber.

[0025] The electrode rods are made of tungsten, molybdenum, titanium nitride, or carbon.

[0026] An actuation system for the aforementioned electrically controlled pyrotechnic device further includes a signal detection source, a main charge, and a command decision system disposed within a logic chip;

[0027] External signal sources are set in the detection and sensing area of ​​missiles or flying warheads to detect and receive information about the external battlefield or flight environment, and transmit the information data to the command and decision system of the logic chip. The logic chip performs information identification and command decision-making, and determines the opening and closing of time delay relay modules at different positions on the electronically controlled pyrotechnics through a TTL level communication network. The opening and closing of the relays determines whether the branch circuit is conductive. In the branch circuit where the relay is closed, the electronically controlled pulse plasma generator outputs a high-temperature plasma shock wave to detonate the main charge. In the branch circuit where the relay is open, the electronically controlled pulse plasma generator does not respond and the lower charge is not detonated.

[0028] Compared with the prior art, the significant advantages of this invention are:

[0029] (1) The electrically controlled pyrotechnic agent used in the electrically controlled pyrotechnic product of the present invention cannot be activated under open flame, bullet shooting, strong electromagnetic interference and extreme mechanical environment, and has ultra-insensitive characteristics.

The capacitor 1 is connected to the bottom of the nested body 7 by a thread, and the two are coaxial. It should be noted that the supercapacitor only supplies power to the main circuit, and the logic chip 2 is in low-energy self-powered mode.
