Description

Technical Field

[0001] The present invention belongs to the technical field of aviation equipment testing, and particularly relates to a testing method and system for a flare dispensing system of a large fixed-wing rain enhancement operation aircraft. Background Art

[0002] The rain enhancement operation aircraft is equipped with a flare dispensing system for silver iodide dispensing. After the silver iodide composite flare agent is electrically ignited and burned, a large amount of silver iodide aerosol is generated, forming cloud aerosol particles with strong surface ice-forming activity and high nucleation rate. The flare agent is dispensed into the cloud in a fixed direction by the aircraft, and through the power diffusion of the aircraft, the catalytic depth is enhanced. The flare dispensing system consists of an airborne flare dispenser controller, an airborne flare dispenser, and dispensing flares. Among them, the airborne flare dispenser controller uploads the status of the airborne flare dispenser (including parameters such as the power-on status of the airborne flare dispenser, the loading position and quantity of the dispensing flares, etc.), and receives control signals such as "dispensing" output by the display control computer. The airborne flare dispenser is used to load the dispensing flares, and after receiving the ignition signal, it emits an ignition current to ignite the dispensing flares. The silver iodide flare agent in the dispensing flares starts to burn to form aerosol, and diffuses to the cloud along the aircraft trajectory.

[0003] The currently used functional testing method is to remove the flare agent of the dispensing flare, lead out the test wire from the inside of the dispensing flare, and externally connect a small explosion package. The loading position and quantity of the dispensing flares are determined by inserting the electrodes at the front end of the dispensing flare into the corresponding sockets. The corresponding sockets form a circuit to feedback the filling signal, which is finally displayed in the corresponding area on the display. When performing the dispensing operation, the airborne flare dispenser controller outputs an ignition signal to the corresponding socket of the flare dispenser. The ignition signal forms an ignition current through the built-in igniter of the dispensing flare and outputs it to the small explosion package, triggering the explosion of the small explosion package, indicating that the dispensing action is completed.

[0004] The above method has the following drawbacks: 1. Removing the flare agent of the dispensing flare and leading out the test wire requires test modification of the dispensing flare (installing a small explosion package). After the test is completed, it needs to be restored and filled with the flare agent. This not only increases the workload of test modification, but also affects the sealing effect of the dispensing flare, easily leading to problems such as poor contact of the dispensing flare wire and moisture absorption of the flare agent; 2. The externally connected small explosion package is a disposable item. If multiple repeated verifications are required during functional testing, after each dispensing operation, the small explosion package needs to be installed on the dispensing flare in sequence, with a heavy workload; 3. The externally connected small explosion package is an explosive device, which has strict requirements for transportation and storage, with a high usage cost. Moreover, the explosive device cannot meet the functional testing requirements in the laboratory or assembly workshop (the use of inflammable and explosive items is prohibited in a closed space), and the applicable range is limited. Summary of the Invention

[0005] The object of the present invention is to provide a method and system for testing the flare dispensing of a large fixed-wing rain enhancement operation aircraft, which is used to solve the problems of heavy workload, high use cost and limited application scope of the existing flare dispensing system. It can complete multiple test verifications without disassembly according to actual test requirements, and can meet the test requirements in the R & D stage and mass production stage.

[0006] The technical solution of the present invention is realized as follows: In the first aspect, the present invention provides a method for testing the flare dispensing of a large fixed-wing rain enhancement operation aircraft, which includes the following steps: Connect the airborne flare dispensing controller and the airborne flare dispenser; Fill the simulated flares into the corresponding flare sockets of the airborne flare dispenser according to requirements; Power on and check whether the filling position of the simulated flare is consistent with the filling position of the simulated flare displayed on the airborne display; If they are consistent, select the simulated flare to be dispensed on the man-machine interface and click the "Dispense" button; Check whether the indicator light of the selected simulated flare is lit; If it is lit, it means that the simulated flare has received the "ignition" signal; At the same time, check whether the corresponding simulated flare on the airborne display is in the dispensing state.

[0007] As a further solution of the present invention: the airborne flare dispensing controller automatically outputs a detection current of 0.02 A to the flare socket of the airborne flare dispenser. The flare socket without a filled simulated flare cannot form a circuit and is an open circuit signal; The flare socket filled with the simulated flare feeds back a filling signal to the airborne flare dispensing controller.

[0008] As a further solution of the present invention: the airborne flare dispensing controller processes the filling signal and transmits it back to the airborne display and control computer, and the airborne display and control computer outputs the filling signal to the corresponding area of the airborne display to display the filling state of the simulated flare at the corresponding position.

[0009] As a further solution of the present invention: after selecting the simulated flare and clicking the "Dispense" button on the man-machine operation interface, the airborne display and control computer outputs a dispensing control signal to the airborne flare dispensing controller, and the airborne flare dispensing controller outputs an ignition signal to the ignition controller of the airborne flare dispenser. The ignition controller outputs an ignition current of 1 A to the flare socket. The flare socket without a filled simulated flare cannot form a circuit and does not perform the ignition action; On the flare socket filled with the simulated flare, after the simulated flare receives the ignition current, it goes through the built-in resistor to the indicator light. After the indicator light is powered on, it lights up, indicating that the simulated flare has received the ignition signal.

[0010] In a second aspect, the present invention provides a flare dispensing test system for a large fixed-wing rain enhancement operation aircraft, which includes: A simulated flare, which has an indicator light and an ignition electrode connected by an internal wire; An airborne flare dispenser for loading the simulated flare, which has a flare socket and an ignition controller connected by an internal wire; An airborne flare dispensing controller for performing signal interaction with the airborne flare dispenser to determine whether the simulated flare is loaded and whether it is dispensed.

[0011] As a further aspect of the present invention: an insulating plug is provided at the front end of the simulated flare, and two ignition electrodes are both inserted into the insulating plug, and a load resistor is also connected in series between the indicator light and the ignition electrode.

[0012] As a further aspect of the present invention: the airborne flare dispenser is internally provided with a fixed bracket and a socket fixing frame, and a plurality of simulated flare loading positions are provided on the fixed bracket, and a plurality of flare sockets corresponding to the loading positions are provided on the socket fixing frame.

[0013] As a further aspect of the present invention: the airborne flare dispensing controller is connected to the ignition controller through a flare aviation socket and an internal wire.

[0014] As a further aspect of the present invention: the airborne flare dispensing controller is also connected to an airborne display and control computer, and the airborne display and control computer is connected to an airborne display.

[0015] As a further aspect of the present invention: the airborne flare dispensing controller and the airborne flare dispenser are original airborne equipment; The simulated flare has the same structure as the actual dispensed flare, does not fill the pyrotechnic agent but is additionally equipped with an indicator light.

[0016] The beneficial effects of the present application are as follows: 1. The simulated flare of the present application has the same parameters as the dispensed flare, such as specification size, control voltage and current, etc., and can be directly installed on the airborne flare dispenser for testing. During testing, it is not necessary to perform test modifications on the airborne flare dispensing system, reducing the test workload.

[0017] 2. The airborne flare dispensing controller and the airborne flare dispenser used in the present application are both airborne equipment, and the simulated flare is modified from the dispensed flare. During testing, it is not necessary to separately support additional test equipment, reducing the preparation workload and lowering the test cost.

[0018] 3. The present application can complete multiple test verifications without disassembly and assembly according to actual test requirements, and can meet the test requirements in the R & D stage and the mass production stage.

[0019] 4. The present application uses an indicator light to replace the pyrotechnic device (small explosive package) to indicate the working state of the flare strip, and can complete the function test of the airborne flare strip dispensing control system in a relatively enclosed space such as a laboratory or an assembly workshop, improving the applicability of the test.

[0023] To make the purpose, technical solutions and advantages of the implementation of the present invention clearer, the technical solutions in the embodiments of the present invention will be described in more detail below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of the present invention.

[0025] The embodiments described below by reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0026] The following combines the attached Figure 1 The embodiments of the present invention are described in detail.

[0027] Embodiment 1 The present invention provides a method for testing the flare strip dispensing of a large fixed-wing rain enhancement operation aircraft, which includes the following steps: Connect the airborne flare strip dispensing controller 9 and the airborne flare strip dispenser 1; Fill the simulated flare strip 8 into the corresponding flare strip socket 10 of the airborne flare strip dispenser 1 as required; Power on and check whether the filling position of the simulated flare strip 8 is consistent with the filling position of the simulated flare strip 8 displayed on the airborne display 12; If they are consistent, select the simulated flare strip 8 to be dispensed on the man-machine interface and click the "Dispense" button; Check whether the indicator light of the selected simulated flare 8 is lit; If it is lit, it means that the simulated flare 8 has received the "ignition" signal; At the same time, check whether the corresponding simulated flare 8 on the on-board display 12 is in the spreading state.

[0028] Further, the on-board flare spreading controller 9 automatically outputs a detection current of 0.02 A to the flare socket 10 of the on-board flare spreader 1. The flare socket 10 without the filled simulated flare 8 cannot form a circuit, which is an open circuit signal; The flare socket 10 filled with the simulated flare 8 feeds back a filling signal to the on-board flare spreading controller 9.

[0029] Further, the on-board flare spreading controller 9 processes the filling signal and sends it back to the on-board display and control computer 11. The on-board display and control computer 11 outputs the filling signal to the corresponding area of the on-board display 12 to display the filling state of the simulated flare 8 at the corresponding position.

[0030] Further, when the simulated flare 8 is selected on the man-machine operation interface and the "spread" button is clicked, the on-board display and control computer 11 outputs a spread control signal to the on-board flare spreading controller 9. The on-board flare spreading controller 9 outputs an ignition signal to the ignition controller 4 of the on-board flare spreader 1. The ignition controller 4 outputs an ignition current of 1 A to the flare socket 10. The flare socket 10 without the filled simulated flare 8 cannot form a circuit and does not perform the ignition action; On the flare socket 10 filled with the simulated flare 8, after the simulated flare 8 receives the ignition current, it goes through the built-in resistor to the indicator light. After the indicator light is powered on, it lights up, indicating that the simulated flare 8 has received the ignition signal.

[0031] Specifically: Fill the simulated flare 8 into the on-board flare spreader 1. The corresponding flare socket 10 of the on-board flare spreader 1 forms a circuit. The filling signal is fed back to the on-board flare spreading controller 9 via the built-in wire 6 and the flare aviation socket 7. The on-board flare spreading controller 9 calculates the filling signal and outputs it to the on-board display and control computer 11, and is displayed in the corresponding area of the on-board display 12. The flare is displayed in blue. Select the flare to be spread on the man-machine operation interface and click the "spread" button. After the on-board flare spreading controller 9 receives the "spread" signal sent by the on-board display and control computer 11, it outputs an ignition signal via the flare aviation socket 7 and the built-in wire 6 to the ignition controller 4 of the on-board flare spreader 1. The ignition controller 4 outputs an ignition current to the flare socket 10. The flare socket 10 conducts the ignition current into the simulated flare 8. When the simulated flare indicator light lights up, it means that the ignition control function of the on-board flare spreading controller 9 is normal. At the same time, the signal is fed back, and finally the corresponding flare on the on-board display 12 gradually changes color to indicate that it is burning.

[0032] Embodiment 2 The present invention provides a test system for flare dispensing of a large fixed-wing rain enhancement operation aircraft, which includes: A simulated flare 8, which has an indicator light and an ignition electrode connected by an internal wire 6; An airborne flare dispenser 1 for loading the simulated flare 8, which has a flare socket 10 and an ignition controller 4 connected by an internal wire 6; An airborne flare dispensing controller 9 for performing signal interaction with the airborne flare dispenser 1 to determine whether the simulated flare 8 is loaded and whether it is dispensed.

[0033] In this solution, the simulated flare 8 is loaded into the airborne flare dispenser 1 to replace the dispensing flare for testing, and the functions of the flare dispensing control system are verified, including the filling position recognition function and the ignition control function of the dispensing flare.

[0034] Further, an insulating plug is provided at the front end of the simulated flare 8, and two ignition electrodes are inserted into the insulating plug. A load resistor is also connected in series between the indicator light and the ignition electrode.

[0035] Further, the airborne flare dispenser 1 is internally provided with a fixed bracket 2 and a socket fixing frame 3, and a plurality of loading positions for the simulated flare 8 are provided on the fixed bracket 2, and a plurality of flare sockets 10 corresponding to the loading positions are provided on the socket fixing frame 3. The fixed bracket 2 is similar to a honeycomb structure, and the loading positions are all designed as round holes and are adapted to the simulated flare 8. Two annular mounting parts are provided on the socket fixing frame 3, and a plurality of flare sockets 10 are provided on each annular mounting part, and a connecting support rod is provided between adjacent two flare sockets 10, and all the flare sockets 10 are connected in parallel. The airborne flare dispenser 1 includes a front fairing 5 and an installation cavity, the fixed bracket 2 is arranged in the installation cavity, the socket fixing frame 3 is arranged at the connection between the front fairing 5 and the installation cavity, the ignition controller 4 is arranged in the front fairing 5, and the flare aviation socket 7 is arranged on the front fairing 5, and the two are connected by an internal wire 6.

[0036] Further, the airborne flare dispensing controller 9 is connected to the ignition controller 4 through the flare aviation socket 7 and the internal wire 6.

[0037] Further, the airborne flare dispensing controller 9 is also connected to an airborne display and control computer 11, and the airborne display and control computer 11 is connected to an airborne display 12.

[0038] Further, the airborne flare dispensing controller 9 and the airborne flare dispenser 1 are original airborne equipment; The simulated flare 8 has the same structure as the actual dispensed flare, without filling with flare agent but equipped with an additional indicator light. The simulated flare 8 is modified from the dispensed flare, and the structural parameters such as the specification dimensions and the electrical parameters such as the control voltage and ignition current of the simulated flare 8 are the same as those of the dispensed flare. The indicator light of the simulated flare 8 is used to replace the pyrotechnic device (small explosion package) of the dispensed flare to indicate the working state of the flare.

[0039] Specifically as follows: An airborne flare dispensing controller 9, an airborne flare dispenser 1, and a simulated flare 8. Among them, the airborne flare dispensing controller 9 and the airborne flare dispenser 1 are the original airborne equipment; the simulated flare 8 has the same structure as the dispensed flare, without filling with flare agent but equipped with an additional indicator light. Before the test, the simulated flare 8 is loaded onto the fixed bracket 2 of the airborne flare dispenser 1. During the test, the aircraft is powered on and the power supply of the airborne flare dispensing system is turned on according to the operation procedure. The airborne flare dispensing controller 9 automatically outputs a detection current of 0.02 A to the flare socket 10 of the airborne flare dispenser 1. The socket without the loaded simulated flare cannot form a circuit and is an open-circuit signal; the flare socket 10 loaded with the simulated flare 8 feeds back the loading signal through the built-in wire 6 and the flare aviation socket 7 to the airborne flare dispensing controller 9. After the airborne flare dispensing controller 9 processes the signal, it is transmitted back to the airborne display and control computer 11, and the airborne display and control computer 11 outputs the signal to the corresponding area of the airborne display 12 to display the loading state of the flare at the corresponding position (the flare is displayed in blue). When the simulated flare 8 is selected on the man-machine operation interface and the "dispense" button is clicked, the airborne display and control computer 11 outputs a dispense control signal to the airborne flare dispensing controller 9. The airborne flare dispensing controller 9 outputs an ignition signal through the flare aviation socket 7 and the built-in wire 6 to the ignition controller 4 of the airborne flare dispenser 1. The ignition controller 4 outputs an ignition current of 1 A to the flare socket 10. The flare socket 10 without the loaded simulated flare 8 cannot form a circuit and does not perform the ignition action; the flare socket 10 loaded with the simulated flare 8 forms a circuit. After the simulated flare 8 receives the ignition current, it goes through the load resistor to the indicator light, and the indicator light lights up after being powered on, indicating that the simulated flare 8 has received the ignition signal.

[0040] The present invention integrates an airborne flare dispenser controller, an airborne flare dispenser, and simulated flares, providing a complete functional test solution for the flare dispensing system and simplifying the test process. At the same time, by using simulated flares with the same structural and electrical parameters as the dispensed flares, they can be directly installed on the airborne flare dispenser for testing. During testing, there is no need to perform test modifications on the airborne flare dispensing system, nor is it necessary to separately equip additional test equipment, reducing the workload of test preparation and the test cost. After the simulated flares are installed, repeated testing can be carried out, and multiple test verifications can be completed without disassembly and assembly, meeting the test requirements in the R & D stage. More importantly, using indicator lights instead of pyrotechnics (small explosive packages) to indicate the working state of the flares can meet the functional test requirements in relatively enclosed spaces such as laboratories or assembly workshops, improving the applicability of the test.

[0041] The working method is as follows: After installing the airborne flare dispenser controller and the airborne flare dispenser in place, connect the corresponding cable plugs. Install the simulated flares on the corresponding flare sockets of the airborne flare dispenser as required, and check whether the electrodes at the front of the simulated flares are installed in place. After turning on the power on the aircraft, check whether the installation position of the simulated flares on the airborne flare dispenser is consistent with the position of the loaded flares displayed on the monitor. Select the flares to be dispensed on the man-machine interface, click the "Dispense" button, and check whether the indicator lights of the simulated flares at the selected position light up (instantly). If the indicator lights are on, it means that the simulated flares have received the "ignition" signal, and check whether the corresponding simulated flares on the monitor are in the dispensing state.

[0042] Thus, the object of the present invention is achieved.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
