Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0020] The purpose of this invention is to provide an ignition test apparatus for electrically controlled solid propellants, so as to solve the technical problems of poor contact between the electrodes and the propulsion device during ignition of existing test apparatuses and the difficulty in venting flame gases.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-2 As shown, this embodiment provides an ignition test device 100 for electrically controlled solid propellants, including a platform base, an anode base 6, a cathode base 7, a propellant chamber 11, a spring-assisted propulsion mechanism, an anode 10, and a cathode 8. The anode base 6 and cathode base 7 are movably mounted on the platform base, and the distance between them can be adjusted and fixed to facilitate the adjustment and fixing of the distance between the cathode 8 and anode 10, enhancing the flexibility of the device and simplifying operation. The anode 10 is mounted on the anode base 6, and the propellant chamber 11 is mounted on the cathode base 7. The spring-assisted propulsion mechanism is located within the propellant chamber 11, and the cathode 8 is located at the end of the spring-assisted propulsion mechanism away from the cathode base 7. The propellant is pressed into the propellant chamber 11 using a press-in loading method. The spring-assisted propulsion mechanism helps prevent poor contact between the propellant and the electrode after ignition. The anode 10 is a mesh electrode, effectively ensuring the release of flame gases.

[0023] Specifically, the platform base includes a support platform 1 and four legs 2. The four legs 2 are respectively installed at the four corners of the lower end face of the support platform 1 by screws. The legs 2 are used to support the support platform 1.

[0024] The ignition test apparatus 100 for electrically controlled solid propellants provided in this embodiment also includes four sliding shaft seats 3 and two sliding shafts 4. The two sliding shafts 4 are arranged in parallel, and two sliding shaft seats 3 are slidably installed on one sliding shaft 4. The sliding shaft seats 3 can slide back and forth along the length direction of the sliding shaft 4, thereby achieving a limiting function by moving the position of the sliding shaft seats 3. The anode base 6 and the cathode base 7 are both located between the four sliding shaft seats 3, and the sliding shaft seats 3 can be fixed on the platform base to achieve fixed positioning when moved into place.

[0025] The sliding bearing seat 3 is fixed to the platform base by screws. The sliding shaft 4 and the sliding bearing seat 3 are fixed by screwing the limiting screw into the side of the sliding bearing seat 3, thereby fixing the sliding bearing seat 3 relative to the sliding shaft 4 and fixing the position of the sliding shaft 4.

[0026] The ignition test apparatus 100 for electrically controlled solid propellants provided in this embodiment also includes two support sliders 5. Both support sliders 5 are slidably connected to two sliding shafts 4, and the support sliders 5 can reciprocate along the length direction of the sliding shafts 4. The anode base 6 and the cathode base 7 are respectively installed on different support sliders 5 by screws, so that the two support sliders 5 drive the cathode base 7 and the anode base 6 to move respectively, so as to realize the distance adjustment between the cathode base 7 and the anode base 6. The sliding shafts 4 and the support sliders 5 are fixed by screwing the limiting screws into the side of the support sliders 5, so as to realize the fixation after the distance adjustment.

[0027] The propellant chamber 11 includes a connecting ring and a cylinder. The connecting ring is installed on the cathode base 7 by screws. The cylinder is hollow inside and open at both ends. The connecting ring is coaxially fixed to one end of the cylinder. Four elongated slots are circumferentially opened at the other end of the cylinder. The four support ridges of the cathode 8 are respectively embedded in the four elongated slots, and the support ridges can slide back and forth in the elongated slots. The setting of the support ridges and elongated slots can cooperate with the spring-assisted propulsion mechanism to assist the propulsion of the propellant.

[0028] The spring-assisted propulsion mechanism is located inside the cylinder. The spring-assisted propulsion mechanism includes two spring limit seats 9 and a spring 12. One spring limit seat 9 is installed on the cathode base 7 by screws, and the other spring limit seat 9 is installed on one side of the cathode 8 by screws. The two ends of the spring 12 are respectively inserted into the two spring limit seats 9.

[0029] The anode 10 is fixed to the anode base 6 by screws.

[0030] Using the ignition test apparatus 100 for electrically controlled solid propellants provided in this embodiment, by adding a support slider 5 below the anode base 6 and the cathode base 7, the position can be moved flexibly, and the propellant can be replaced simply by loosening the limiting screw on the side of the support slider 5 that cooperates with the cathode base 7, without the need for extensive disassembly. This greatly simplifies the process of repeated testing; it combines the advantages of the mesh screen electrode effectively releasing flame gases and the spring-assisted propulsion mechanism ensuring reliable contact between the electrode and the propellant.

S5, connect the anode base 6 and the anode 10 with screws, and tighten the limiting screws on the side of the support slider 5 that cooperates with the anode base 6, so that the support slider 5 is fixed to one end of the sliding shaft 4; S6, connect the cathode base 7 and the cathode 8, and the cathode 8 and the spring limiting seat 9 with screws; S7, connect the cathode base 7 and the pressing chamber 11 with screws; S8, insert the spring 12 between the two spring limiting seats 9, and align the four supporting edges of the cathode 8 with the four slots of the pressing chamber 11.
