Description

Technical Field

[0001] The present invention belongs to the technical field of parachute cabin isolation devices, and more specifically, relates to a parachute cabin isolation device capable of preventing rotation and installing a balloon parachute. Background Art

[0002] With the continuous development of my country's aerospace technology, the use of various aerospace equipment is becoming increasingly frequent and widespread. A parachute is a decelerator that deploys by inflating relative to the air, utilizing the principle of air resistance. With the continuous advancement of parachute technology, the application of parachutes is also expanding. They are now widely used in airborne drop, airborne deceleration, emergency rescue, and aircraft recovery.

[0003] The parachute compartment isolation device used in the parachute field, on the one hand, plays the role of closing the parachute compartment when the parachute is not activated, and on the other hand, can play the role of pulling the parachute out when the parachute is activated.

[0004] However, during the parachute activation process, certain weapons and ammunition generate high spin due to the firing conditions. For such weapons and ammunition, traditional parachutes are very prone to the problem of parachute rope entanglement. In the existing technology, multi-stage parachutes are usually used to gradually achieve spin reduction and deceleration to address the above-mentioned parachute rope entanglement problem. The first parachute (first stage parachute) in the multi-stage parachute often uses a balloon parachute (ram-inflated spherical stabilized reducer). At the same time, due to the high rotation speed of the weapons and ammunition, the parachute compartment isolation device will cause rotation relative to the parachute compartment, twisting off the connecting parts connecting the parachute compartment and the parachute compartment isolation device, thereby causing the parachute compartment isolation device to separate from the parachute compartment prematurely, and finally causing the second stage parachute in the parachute compartment to operate prematurely, and the problem of anti-spin is still not solved. Summary of the Invention

[0005] To address the aforementioned shortcomings or improvements in the prior art, the present invention provides a parachute compartment isolation device and installation method that can prevent rotation and accommodate a balloon parachute. One end of the anti-rotation pin is installed in a anti-rotation pin mounting hole in the main cover plate, and the other end is installed in a connecting hole in the parachute compartment. This prevents the parachute compartment isolation device and the parachute compartment from rotating under decelerated load and high-speed operating conditions, preventing the parachute compartment isolation device's connector from twisting and breaking, and ensuring that the parachute system operates according to its intended operating procedures.

[0006] To achieve the above object, according to one aspect of the present invention, there is provided a parachute compartment isolation device capable of preventing rotation and installing a balloon parachute, the parachute compartment isolation device comprising a main cover plate; and

[0008] One end of the anti-rotation pin shaft is fixed in the anti-rotation pin shaft mounting hole, and the other end is fixed in the mounting hole of the parachute cabin to prevent the parachute cabin isolation device and the parachute cabin from rotating relative to each other when the weapon and ammunition enters high-speed rotation after being fired.

[0009] As a further improvement of the present invention, a plurality of mounting hole rings are formed on the main cover plate around its center, forming first to fourth mounting hole rings from the inside to the outside.

[0010] As a further improvement of the present invention, a number of secondary umbrella connecting holes are provided along the first mounting hole ring for installing the secondary umbrella; a number of the balloon umbrella mounting holes are provided along the second mounting hole ring for installing the first-stage balloon umbrella; a number of the parachute cabin connecting piece mounting holes are provided along the third mounting hole ring for installing the parachute warehouse connecting piece; and the anti-rotation pin shaft mounting holes are provided along the fourth mounting hole ring for installing the corresponding rotation pin shaft.

[0011] As a further improvement of the present invention, the secondary umbrella connecting hole, balloon umbrella mounting hole, parachute cabin connecting piece mounting hole and anti-rotation pin shaft mounting hole are respectively evenly spaced and arranged in multiples on the first mounting hole ring, the second mounting hole ring, the third mounting hole ring and the fourth mounting hole ring.

[0012] As a further improvement of the present invention, the anti-rotation pin shaft mounting hole, the balloon parachute mounting hole, the secondary parachute connecting hole and the parachute cabin connecting piece mounting hole are respectively arranged symmetrically along the center point.

[0013] As a further improvement of the present invention, the main cover plate connecting surface is a circular structure.

[0014] According to another aspect of the present invention, a method for installing a parachute compartment isolation device capable of preventing rotation and installing a balloon parachute is provided, which is used for installing the parachute compartment isolation device capable of preventing rotation and installing a balloon parachute and its connecting components, and is characterized in that:

[0015] Install the first-stage balloon parachute on the balloon parachute mounting hole of the main cover through the connecting piece;

[0016] Install the secondary umbrella connecting piece on the secondary umbrella connecting hole of the main cover plate through the connecting piece;

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0029] In order to eliminate the rotation of weapons and ammunition with the parachute cabin under high rotation speed conditions and to meet the needs of installing a balloon parachute, the present invention provides a parachute cabin isolation device that can prevent rotation and install a balloon parachute. Figure 1 This is a structural schematic diagram of a parachute cabin isolation device capable of stopping rotation and installing a balloon parachute according to an embodiment of the present invention. Figure 2 This is a top view of a parachute compartment isolation device capable of preventing rotation and installing a balloon parachute according to an embodiment of the present invention. Figure 1 and Figure 2 As shown, the parachute cabin isolation device of the present invention, which can stop rotation and install a balloon parachute, includes a stop pin shaft 1, a main cover plate 2, a stop pin shaft mounting hole 3, a balloon parachute mounting hole 4, a secondary parachute connecting hole 5 and a parachute cabin connecting piece mounting hole 6.

[0030] Specifically, Figure 1 for Figure 2The cross-sectional structural diagram along AA shows that the parachute compartment isolation device capable of preventing rotation and installing a balloon parachute of the present invention comprises a main cover plate 2, on which are provided a plurality of anti-rotation pin shaft mounting holes 3, balloon parachute mounting holes 4, secondary parachute connecting holes 5 and parachute compartment connecting piece mounting holes 6; the cross section of the main cover plate 2 is preferably a circular structure, and a plurality of mounting hole rings are formed around the center of the circular structure, forming the first to fourth mounting hole rings from the inside to the outside; wherein the first mounting hole ring is provided with a plurality of secondary parachute connecting holes 5, which are evenly spaced and arranged for installing the secondary parachute; the second mounting hole ring There are several balloon parachute mounting holes 4, which are evenly spaced and used to install the first-level balloon parachute; the third mounting hole ring is provided with a parachute cabin connector mounting hole 6, which is used to install the parachute compartment connector; the fourth mounting hole ring is provided with a stop pin shaft mounting hole 3, which is used to install the corresponding stop pin shaft 1. One end of the stop pin shaft 1 is inserted into the stop pin shaft mounting hole 3, and the other end is inserted into the mounting hole of the parachute compartment to fix the parachute compartment and the parachute compartment isolation device, thereby effectively preventing the parachute compartment isolation device and the parachute compartment from rotating relative to each other when the weapon and ammunition enter high-speed rotation after being fired.

[0031] The present invention can stop the rotation of the parachute cabin isolation device and install a balloon parachute. A rotation-stop pin is installed on the main cover plate, which can cooperate with the parachute cabin to prevent the parachute cabin isolation device from rotating relative to the parachute cabin; the main cover plate 1 is also provided with a balloon parachute mounting hole 4, a secondary parachute connecting hole 5 and an parachute cabin connecting piece mounting hole 6, which can serve the purpose of installing other corresponding components.

[0032] During parachute assembly, the first-stage balloon parachute is mounted on the balloon parachute mounting hole 4 of the main cover plate 2 via connectors (preferably screws and nuts), the second-stage parachute connector is mounted on the second-stage parachute connecting hole 5 of the main cover plate 2 via connectors (preferably screws and nuts), and the anti-rotation pin 1 is inserted into the anti-rotation pin mounting hole 3 of the main cover plate 2, with a portion of the anti-rotation pin 1 protruding outward. When the parachute compartment isolation device of the present invention is assembled with the parachute compartment, the protruding end of the anti-rotation pin 1 on the main cover plate 2 is inserted into the parachute compartment mounting hole, and the parachute compartment connector is mounted on the parachute compartment connector mounting hole 6 of the main cover plate 2 via connectors (preferably screws and nuts). Of course, the aforementioned connectors are not limited to screw and nut connections; other connection methods that can achieve the aforementioned mounting, connection, and fixing functions are within the scope of protection of the present invention.

[0033] When weapons and ammunition enter a high-speed rotation state after being fired, the parachute compartment isolation device prevents itself and the parachute compartment from rotating relative to each other through the anti-rotation pin shaft 1. When the parachute system starts working, the first-stage balloon parachute installed on the parachute compartment isolation device transmits force through the anti-rotation pin shaft 1 and the parachute compartment connector to slow down and reduce the rotation of the weapons and ammunition.

[0034] Furthermore, when the secondary parachute issues a working instruction, the parachute compartment connector pushes the parachute compartment isolation device outward according to a predetermined program. At the same time, the parachute compartment isolation device pulls out the connected secondary parachute through the secondary umbrella connection hole 5 on the main cover plate 2, completing the startup of the secondary parachute.

[0035] The present invention provides a parachute cabin isolation device that can stop rotation and can be installed with a balloon parachute. The main cover plate is provided with installation holes for a rotation-stop pin shaft, a balloon parachute, a secondary parachute and a parachute cabin connecting piece for installing corresponding components. One end of the rotation-stop pin shaft is installed in the rotation-stop pin shaft installation hole of the main cover plate, and the other end is installed in the connecting hole on the parachute cabin, which is used to prevent the parachute cabin isolation device and the parachute cabin from rotating relative to each other.

[0036] The present invention provides a parachute-cabin isolation device with anti-rotation capabilities and the ability to accommodate a balloon parachute. The anti-rotation pin prevents the parachute-cabin isolation device and the parachute cabin from rotating under decelerated load and high-speed conditions, preventing the parachute-cabin isolation device connector from twisting and breaking, ensuring the proper operation of the parachute system. The main cover plate includes mounting holes for the first-stage balloon parachute, the parachute cabin connector, and the second-stage parachute. The device features a simple structure and excellent practicality, making it widely applicable to weapon and ammunition parachute systems requiring anti-rotation and deceleration.

[0037] The method for installing a parachute cabin isolation device capable of preventing rotation and installing a balloon parachute of the present invention comprises the following steps:

[0038] Install the first-stage balloon parachute on the balloon parachute mounting hole 4 of the main cover plate 2 through the connecting piece;

[0039] Install the secondary umbrella connector on the secondary umbrella connecting hole 5 of the main cover plate 2 through the connector;

[0040] Insert the anti-rotation pin shaft 1 into the anti-rotation pin shaft mounting hole 3 of the main cover plate 2, and insert the other end into the mounting hole of the parachute cabin;

[0041] The parachute cabin connector is installed on the parachute cabin connector mounting hole 6 of the main cover plate 2 through the connector.

[0042] The present invention provides a method for installing a parachute-cabin isolation device capable of simultaneously mounting a balloon parachute and preventing rotation. This method utilizes a parachute-cabin isolation device capable of simultaneously mounting a balloon parachute and preventing rotation, thereby eliminating rotation relative to the parachute cabin under high-speed rotational conditions of weapons and ammunition, while also accommodating the installation of the balloon parachute. Because the parachute-cabin isolation device includes a rotation-stopping member, it prevents relative rotation between the parachute cabin and the parachute cabin under high-speed rotational conditions of weapons and ammunition. Furthermore, the parachute-cabin isolation device includes mounting holes for the balloon parachute and a mounting hole for a parachute-cabin connector, allowing for connection to the primary balloon parachute and the parachute-cabin connector. This method simplifies installation and reduces costs.

[0043] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
