Description

Technical Field

[0001] This utility model relates to the field of electronic equipment testing technology, specifically to a test cable for live-fire ground connection of aircraft standard interface. Background Technology

[0002] With the rapid development of aviation weapon technology, the types of weapons that aircraft can carry are becoming increasingly diverse, and weapon interfaces are gradually moving towards standardization and universalization. However, in actual use, especially when preparing for live-fire missions (such as missile testing, chain testing, alignment, telemetry signal detection, etc.) or when troubleshooting aircraft malfunctions requires weapons to be powered on and tested, existing technologies have significant shortcomings.

[0003] In the traditional model, weapons need to be transferred from the ammunition transport vehicle to the ammunition loading vehicle via crane, and then transported directly under the corresponding hardpoint for loading. This process is not only time-consuming and labor-intensive, increasing the workload of support personnel, but also poses safety risks such as ammunition falling and mechanical collisions during weapon loading, unloading, and power-on testing, which seriously restricts the efficiency of aircraft takeoff and combat readiness and continuous support capabilities.

[0004] More importantly, with the standardization of weapon interface standards, the requirements for ground testing equipment for different weapon models are becoming more consistent. However, there is a lack of universal testing cables specifically designed for weapons with standard interfaces for this type of aircraft. This forces the military to rely on traditional, high-risk, and inefficient operating methods during live-fire support, making it difficult to meet the urgent needs of modern warfare for rapid response and efficient support. Utility Model Content

[0005] In view of this, the present invention provides a test cable for live-fire ground connection of aircraft standard interface. The present invention can test the various functional modules of the missile without disassembling the missile, thereby avoiding damage during missile mounting.

[0006] To solve the above-mentioned technical problems, this utility model provides a test cable for live-fire ground connection of aircraft standard interface, including discrete signal line group, which is used to test the signal interaction function of missile.

[0007] The power supply cable assembly is used to test the power supply lines of various components inside the missile.

[0008] The address line group is used to detect and provide feedback on the insertion position of the missile detection port.

[0009] The bandwidth line group is used to detect the satellite transmission signal function inside the missile.

[0010] The bus line group is used to detect the data transmission function inside the missile.

[0011] Discrete signal line groups include;

[0012] Deploy the permitting cable, which is used to test the module that confirms whether the missile is in a launch-ready state.

[0013] Interlocking cables are used to detect the continuity or disconnection status of the internal circuitry of a missile.

[0014] Structured ground cables are used to discharge static electricity generated inside the missile.

[0015] The power cord set includes:

[0016] A 28V DC power cable is used to test the power supply for flight control, satellite receiver, seeker, servo motor, data link components, and pyrotechnic activation.

[0017] A 270V DC power supply is used to test the backup power supply.

[0018] The power supply unit also includes a 115V / 400HZ cable, which can power and test various types of aircraft and missiles.

[0019] The address line group includes multiple address bit cables, address parity cables, and address return lines. The address parity cables can verify the position of the inserted address and convert it into data, which is then transmitted through the address return lines.

[0020] The bandwidth cable group includes low-bandwidth cables and multiple high-bandwidth cables. The high-bandwidth cables and ground-bandwidth cables can simulate the transmission of signals to satellites.

[0021] The bus cable group includes MUX cables and fiber optic cables. MUX cables are mainly used for transmitting text-encoded data, while fiber optic cables are mainly used for transmitting larger data (such as video footage).

[0022] Each cable has an outer sheath to provide high-temperature shielding or electromagnetic protection.

[0023] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0024] 1. Improved testing efficiency and shortened support cycle: This utility model integrates discrete signal line groups, power line groups, address line groups, bandwidth line groups, and bus line groups to achieve modular testing of missile signal interaction, power supply, address positioning, satellite communication, and data transmission functions. During the testing process, there is no need to actually mount the missile onto the aircraft, avoiding the time-consuming operations of weapon mounting and dismounting in traditional methods, significantly shortening the preparation time for live-fire missions and improving operational support efficiency.

[0025] 2. Reduce safety risks and ensure personnel and equipment safety: Traditional testing methods require the transfer of weapons by crane and close-range operation, posing safety hazards such as falling ammunition and mechanical collisions. This utility model, through its ground-based joint testing design, keeps the testing operation away from aircraft and weapon mounting points, significantly reducing safety risks and effectively protecting the personal safety of support personnel and the integrity of weaponry.

[0026] 3. Compatible with multiple weapon and aircraft models, expanding applicability: The power cable group is compatible with 28V DC, 270V DC, and 115V / 400Hz AC power supplies; the address cable group supports multi-address bit verification; and the bus cable group integrates fiber optic and MUX bus, adaptable to different missile and aircraft interface standards. This design gives the test cable broad versatility, making it suitable for multiple weapon and aircraft platforms, reducing the types and number of dedicated test equipment, and lowering logistical complexity.

[0027] 4. Improved detection accuracy and full functional coverage: Through real-time monitoring of missile launch authorization, circuit continuity, and static electricity discharge using discrete signal line groups; independent detection of multiple power supply lines using power line groups; simulation verification of satellite signal transmission using bandwidth line groups; and evaluation of data transmission quality using bus line groups, this invention achieves comprehensive detection of key missile functions. The detection results can accurately locate faulty modules, providing data support for weapon system maintenance.

[0028] 5. Enhanced environmental adaptability and ensured testing stability: The cable's outer surface is equipped with a high-temperature shielding and electromagnetic protection layer, effectively resisting adverse factors such as high temperatures and electromagnetic interference in the ground-based testing environment, ensuring the stability of signal transmission and the accuracy of test data. This design is particularly suitable for live-fire support missions in the field or complex electromagnetic environments.

[0029] 6. Simplified operation process and lower technical threshold: This utility model simplifies the connection and operation steps of the testing equipment through modular wire group design and standardized interfaces. Personnel only need to select the corresponding wire group connection according to functional requirements to complete the rapid testing of missiles, eliminating the need for complex professional debugging processes and reducing the technical requirements for operators.

[0030] 7. Promote equipment standardization and reduce life-cycle costs: This utility model is designed for weapons with standardized interfaces, conforming to the trend of weapon interface standardization and promoting the generalization of testing equipment in the air force. By reducing the research and development and procurement costs of dedicated testing equipment and extending the service life of equipment, the life-cycle cost of weapon systems is optimized.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0043] This embodiment provides a test cable for live-fire ground connection of aircraft standard interface, such as... Figure 1 As shown: This includes discrete signal line group 10, power line group 20, address line group 30, bandwidth line group 40, and bus line group 50. One end of this cable is connected to the missile detection port, and the other end is connected to the detection equipment.

[0044] The discrete signal line group 10 is used to detect the missile's signal interaction function, specifically including the release permission cable 11, such as... Figure 1-4As shown: the release authorization cable 11 can simulate sending a release confirmation to the missile. After receiving the signal, the missile transmits the confirmation of launch preparation to the detection equipment through the cable (in actual use, the aircraft's control program will send the missile launch command again, so the ignition device will work to push the missile to launch).

[0045] Discrete signal line group 10 also includes interlocking cables 12, which include interlocking signal output cables and interlocking return cables. These two interlocking cables 12 are supplied by the standard interface weapon according to GJB1188 requirements. They are short-circuited when the missile-mechanical connector is not disconnected and disconnected after disconnection, allowing the aircraft to monitor the weapon's mounting status.

[0046] The discrete signal line group 10 also includes a structured ground cable 13. Connecting the structured ground cable 13 to the missile allows for the discharge of static electricity from inside the missile, thus preventing electromagnetic interference from static electricity to the missile's internal electronic components. (During flight, the aircraft generates static electricity through friction with the aircraft's outer shell. This static electricity can propagate into the missile through the shell. Although most of the static electricity is discharged upon landing, some remains inside the missile.)

[0047] Preferably, the power cord assembly 20 includes two sets of 28V DC power supply cables 21, such as... Figure 2 As shown: Each set of 28V DC power supply cables consists of a 28V DC power supply transmission cable and a return cable. One set of 28V DC power supply cables is used to power the flight controller and satellite receiver, while the other set of 28V DC power supply cables is used to power the seeker, servo motors, data link components, and pyrotechnic devices.

[0048] The power cable group 20 also includes a set of 270V DC power cables 23, which consists of a DC power cable and a return cable. The two sets of 270V DC power cables 23 are used as backup power to provide backup emergency power for the missile.

[0049] Furthermore, the power cable assembly 20 also includes four 115V / 400HZ22 cables, namely 115V / 400HZ22A phase, 115V / 400HZ22B phase, 115V / 400HZ22C phase, and 115V / 400HZ22 middle phase. These four 115V / 400HZ22 cables enable power supply testing for different aircraft models.

[0050] Specifically, the missile has 5 detection ports. The address line group 30 has 5 address bit cables 31 corresponding to the 5 detection ports, which are marked as A0, A1, A2, A3 and A4. It also has an address return line 33 cable and an address parity check 32 cable. That is, when the end of the cable is inserted into the detection port, the address parity check 32 cable can check the position of the detection port and transmit the insertion position and whether it is inserted in place to the detection equipment through the address return line 33.

[0051] Furthermore, the bandwidth cable group 40 includes four high-bandwidth cables 42 and one low-bandwidth cable 41. Normally, only two of the four high-bandwidth cables 42 are used. The high-bandwidth cables 42 are used to transmit signals to the satellite, and the low-bandwidth cable 41 is used to transmit signals to the launching device, thus enabling the control center to sense the missile's position. (In actual combat applications, this is used to detect whether the missile's trajectory has deviated, whether the missile has been intercepted, and whether the missile has accurately landed.)

[0052] Furthermore, the bus group 50 includes two MUX cables 51 and two fiber optic cables 52, named MUXA, MUXB, Fiber Optic 1, and Fiber Optic 2. The two MUX cables 51 are used to transmit text codes and other data, while the two fiber optic cables 52 are used to transmit larger data such as video images.

[0053] It is worth mentioning that each cable has a wrapping layer on its outer surface, specifically:

[0054] Both MUX cables 51 and the low-bandwidth cable 41 are wrapped with Teflon high-temperature silver-plated shielded twisted pair (model AFPF-250).

[0055] All four high-bandwidth cables have Teflon high-temperature silver-plated shielding on their outer surfaces (model AFPF-250).

[0056] The outer surfaces of the two interlocking cables 12, the deployment permit cable 11, the five address bit cable 31, the address return cable 33, and the address parity check cable 32 are all wrapped with Teflon high-temperature silver-plated wire (model AF250 / FF46-2).

[0057] The outer surfaces of the two sets of 28V DC power supply cables 21, 115V / 400HZ 22A phase, 115V / 400HZ 22B phase, 115V / 400HZ 22C phase, 115V / 400HZ 22 middle phase, structural ground cable 13, and 270V DC power supply cable 23 are all wrapped with Teflon high-temperature silver-plated wire (model AF250 / FF46-2);

[0058] Both fiber optic cables 52 have multimode optical fibers wrapped around their outer surfaces.

[0059] Furthermore, the connector at the cable end can be configured as: model J5994 / 4 (compliance standard Q / 21BJ1302-2011), model J5994 / 13-02 (compliance standard Q / 21BJ1302-2011), model J5994 / 3 (compliance standard Q / 21BJ1302-2011), model J5994 / 9-25 (compliance standards Q / 21EJ1302, Q / 21BJ1302-2011, Q / 21EJ1302), or model J1784 / 38-25S (compliance standard GJB1784).

[0060] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0061] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
