Description

Technical Field

[0001] The invention belongs to the technical field of meteorological detection rockets, and in particular relates to a side-opening multi-sonde mounting and separation device. Background Art

[0002] Existing meteorological detection rockets mainly carry sonde payloads. After the rocket reaches a specified altitude, the separation device works to throw the sonde out. The sonde obtains the required meteorological data during the descent.

[0003] At present, meteorological detection rockets carry a small number of sondes each time, that is, each meteorological detection rocket can only complete one sonde separation and detection task, with low detection efficiency and high rocket launch costs. In addition, during the separation process, existing meteorological detection rockets often throw out sondes along the rocket axis and in the direction of flight to complete the separation action. Usually, large parts / components of the rocket warhead (such as fairings, etc.) are thrown out together due to spatial position interference. Large parts / components of the warhead (such as fairings, etc.) are not recovered separately, thereby increasing the excess debris of the rocket. Summary of the invention

[0004] In view of this, the present invention provides a side-opening multi-sonde carrying and separation device, which can carry more than two sondes at the same time, improve detection efficiency, and reduce rocket launch costs. In addition, the side-opening method is adopted, and the separation direction of the sonde has a certain angle with the rocket axis, and there will be no spatial interference with other components during separation, so that the large parts / components of the detection rocket warhead do not need to be separated from the rocket body, reducing the number of large debris fragments generated during the launch of the meteorological detection rocket.

The bottom surface refers to the inner wall surface closest to the central axis of the main shell 4, and the outer wall surface of the extension portion is conformal with the main shell 4; when the carrying and separating device 2 is in a separated state, under the action of the elastic member, the end of the extension portion of the movable shell 3 is abutted against the bottom surface of the groove I, limiting the movable shell 3, so that a set angle is formed between the movable shell 3 and the main shell 4.

[0052] Furthermore, the outer circumferential surface of the main housing 4 is provided with N (N is an even number) openings, and the N openings are evenly distributed along the circumference;

[0053] The number of sliders 6 is The two ejection assemblies 11 on opposite sides share a slider 6, so that the ejection assemblies 11 on opposite sides can be deployed synchronously to ensure the symmetry of the airflow during the movement of the rocket. In a specific embodiment, N is 4.

[0054] See attached Figure 5 , each ejection assembly 11 includes an ejection tube 16, a piston 14 and a gas generator 15;

[0055] The ejection tube 16 is a cylindrical shell with one end closed and the other end open; the ejection tube 16 is fixedly connected to the movable shell 3;

[0058] Working principle:

[0059] When the loading and separation device 2 is in the loading state, the ejection assembly 11 is located in the main shell 4 and cooperates with the corresponding groove II on the support frame 5; the locking releaser 10 locks all shells, and all shells are conformal with the main shell 4.

[0060] The carrying and separating device 2 is in the carrying state and flies up with the meteorological detection rocket. After reaching the specified height, when the sonde 13 needs to be dropped, the carrying and separating device 2 is converted into the separation state;

[0061] When the onboard separation device 2 is converted to a separation state, the locking releaser 10 is unlocked by controlling the time-sharing ignition control device 12, and the front end of the movable shell 3 is separated from the main shell 4 under the action of the torsion spring 9; since the two ejection assemblies 11 on the opposite sides share a slider 6, under the action of the connecting rod 7, the movable shells 3 on the opposite sides are synchronously unfolded; the time-sharing ignition control device 12 excites the gas generator 15 corresponding to the sonde 13 to be launched, and after the gas generator 15 works, the gas generated pushes the piston 14, and then the piston 14 pushes the sonde 13 to be ejected and separated from the rocket.

[0062] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
