Description

Technical Field

[0001] This invention belongs to the field of projectile surface pop-up technology, and relates to pop-up control technology, particularly to a method and apparatus for realizing surface pop-ups as a structural control part of projectile surface pop-ups, which can be based on the state of the missile. Background Technology

[0002] A laser fuze is a fuze system that uses the reflection of laser light from the target surface to identify the target and automatically select the optimal detonation point. Laser fuzes detect targets by receiving the laser beam they emit and the laser beam reflected from the target, eliminating the fuze's dependence on the target itself. This allows for wide-range target detection, meeting the requirements of missiles attacking over a wide area. However, due to the high surface temperature of missiles flying at high speeds, the laser emitter and receiver of traditional laser fuzes, mounted on the missile body surface, are easily affected by the high-temperature environment, thus making accurate target distance measurement impossible.

[0003] Surface pop-up technology refers to the technique of exposing detection devices to the missile surface during flight by using pop-up windows to enable their operation. Because missiles experience high surface temperatures at high speeds, traditional detection devices mounted on the missile surface are susceptible to adverse effects from the high-temperature environment. Pop-up windows protect these devices and allow them to be deployed when needed, enabling them to function. Summary of the Invention

[0004] This invention provides a device and method for creating pop-up windows on the surface of a projectile, which can solve the problem of unstable operation of optical detection devices in a high-temperature environment for a long time when the projectile is falling.

[0005] The technical solution for achieving the objective of this invention is: a device for realizing a projectile surface pop-out window, comprising:

[0006] A fixed platform assembly is fixed to the surface of the projectile; the fixed platform assembly includes a fixed plate, an optical detection launcher, an optical detection receiver, and a push rod assembly; the optical detection launcher and the optical detection receiver are installed inside the fixed plate, and one end of the push rod assembly is installed on the fixed plate;

[0007] The window, fixed to the other end of the push rod assembly of the fixed platform assembly, is used to isolate the optical detection transmitter, optical detection receiver and external environment from direct contact.

[0008] Temperature sensor; mounted on the surface of the projectile, used to detect temperature information and send it to the microprocessor.

[0009] The microprocessor, installed inside the projectile, receives signals from the external temperature sensor, makes a decision, and determines the operating status of the push rod assembly and the propellant ignition device based on the decision.

[0010] The significant advantages of this invention compared to existing technologies are:

[0011] (1) The present invention designs a projectile surface pop-up window device, which can avoid the problem of the detection device being exposed to high temperature environment for a long time;

[0012] (2) The present invention uses a push rod and gunpowder to push open the cover plate, which improves the efficiency and accuracy of the pop-up window;

[0019] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-5 This application will be further described in detail below. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0020] like Figures 1-2 As shown, a device for implementing a pop-up window on the surface of a projectile includes a fixed platform assembly 1, a window 2, a temperature sensor 01, and a microprocessor W. The fixed platform assembly 1 is welded to the surface D of the projectile and is used to position and fix the push rod assembly and the optical detection transceiver. The window 2 is welded to the fixed platform assembly 1 and is used to isolate the optical detection transceiver from direct contact with the external environment. The temperature sensor 01 detects temperature information and sends it to the microprocessor W. The microprocessor W receives the signal from the external temperature sensor 01 of the projectile, makes a decision, and determines the working state of the push rod and the propellant ignition device based on the decision result.

[0021] like Figure 3 The fixed platform assembly 1 mainly includes a fixed plate 11, an optical detection transmitter 12, an optical detection receiver 13, and a push rod assembly 14.

[0022] The fixed plate 11 has a push rod assembly mounting hole 15, an optical detection transmitter window 16, and an optical detection receiver window 17.

[0023] The push rod assembly mounting hole 15 is used to install the push rod assembly 14. The optical detector transmitter 12 and optical detector receiver 13 are installed in the fixing plate 11, and the optical detector signals are transmitted and received outward through the optical detector transmitter window 16 and the optical detector receiver window 17.

[0024] The push rod assembly 14 is used to push out the cover plate 22 in the window 2. The push rod assembly 14 includes a push rod motor 141, a bottom screw 142, a push rod 143, and a top plate 144. The push rod 143 is fixedly connected to the output shaft of the push rod motor 141. The push rod motor 141 controls the retraction and extension of the output shaft of the push rod motor 141 by receiving signals from the microprocessor W, thereby driving the push rod 143 to perform a pushing and retraction action. The bottom screw 142 is connected to the push rod 143 by a threaded structure and is installed on the push rod assembly mounting hole 15 by welding, which serves to connect the push rod assembly 14 and the push rod assembly mounting hole 15. One end of the top plate 144 is connected to the push rod 143 by welding, and the other end is fixedly connected to the cover plate 22. The function of the top plate 144 is to increase the force-bearing area of ​​the push rod pushing out the cover plate 22.

[0025] like Figure 4 As shown, the window 2 mainly includes: a connecting plate 21, a cover plate 22, an electric ignition head 23, and gunpowder 24. The connecting plate 21 is connected to the fixing plate 11 by welding, so that the window 2 and the platform assembly 1 are connected. There is a groove between the cover plate 22 and the connecting plate 21. The electric ignition head 23 and the gunpowder 24 are placed in the groove. The electric ignition head 23 is controlled by the microprocessor W. After receiving the ignition signal from the microprocessor W, it ignites the gunpowder 24. The impact force after the gunpowder 24 is ignited separates the connecting plate 21 and the cover plate 22. Under the pushing force of the top plate 144, the cover plate 22 is pushed out, so that the optical detection transmitter 12 and the optical detection receiver 13 start to receive external environmental signals and start working.

[0026] The electric ignition head 23 includes: a metal electrode 231, a wire 232, and a control circuit module 233; the metal electrode 231 is connected to the control circuit module 233 by the wire 232. When the control circuit module 233 receives a signal from the microprocessor W, it will supply power to the metal electrode 231 to generate a high-temperature electric arc to ignite the gunpowder 24.

[0027] The length of the push rod is 20cm;

[0028] The top plate moves 10-15cm.

[0029] Temperature sensor 01 is mounted on the surface of the projectile. It uses a thermal resistor made of high-temperature resistant materials, such as platinum-rhodium alloy or tungsten carbide, as the measuring element in high-temperature environments. The key parts of the temperature sensor need to use high-temperature alloys to ensure stability and tolerance at high temperatures. It is a temperature sensor with analog output (voltage or current signal) or digital output (digital temperature value) to send the detected temperature information to the microprocessor W.

[0030] The microprocessor W, installed inside the projectile, can be a digital signal processor, an application-specific integrated circuit (ASIC), or a field-programmable gate array (FPGA).

[0031] The working principle of the projectile surface pop-up window device of the present invention is as follows: the external temperature sensor 01 senses the environmental state and sends it to the microprocessor W. The microprocessor W controls the electric ignition head 23 in the groove of the window 2 and the push rod motor 141 on the fixed platform assembly 1. The electric ignition head 23 ignites the gunpowder 24. The impact of the ignited gunpowder 24 separates the cover plate 22 from the connecting plate 21. The push rod motor 141 on the fixed platform assembly 1 controls the push rod 143 to push the top plate 144 to pop out the cover plate 22. The optical detection transmitter 12 and the optical detection receiver 13 on the fixed platform assembly 1 then start working.

[0032] This invention discloses a method for implementing a pop-up window on the surface of a projectile; the pop-up window method is mainly implemented by a fixed platform component 1, a window 2, a temperature sensor 01, and a microprocessor W;

[0033] like Figure 5 As shown, the specific steps include:

[0034] In step S101, the external temperature sensor 01 senses the environmental state and sends it to the microprocessor W, which then controls the electric ignition head 23 in the recess of window 2 and the push rod motor 141 on the fixed platform assembly 1.

[0035] In step S102, the microprocessor W receives the signal from the external temperature sensor 01 of the projectile, makes a decision, and determines the working state of the electric ignition head 23 and the push rod motor 141 based on the decision result.

[0036] In step S103, the electric igniter 23 ignites the gunpowder 24, separating the cover plate 22 from the connecting plate 21. The push rod motor 141 on the fixed platform assembly 1 controls the push rod 143 to push the top plate 144 to pop out the cover plate 22. The optical detection transmitter 12 and the optical detection receiver 13 on the fixed platform assembly 1 then begin to work.

[0037] Specifically, in step S101 above, the external temperature sensor 01 mainly senses the temperature of the external environment, and the sensing range is within 1400K.

[0038] Specifically, in step S101 above, the microprocessor W is controlled by the power switch of the electric ignition head 23 and the push rod motor 141.

[0039] Specifically, in step S102 above, after receiving the signal from the temperature sensor 01, the microprocessor W makes a decision and controls the push rod motor 141 and the electric ignition head 23 to start working when the external temperature is below 1200K.

[0040] The method for implementing pop-up windows on the surface of a projectile provided by this invention can complete the pop-up windowing within a relatively small space. The pop-up windowing method employed in this invention uses electric control, thus enabling rapid and efficient implementation of the pop-up windowing.
