Description

Technical Field

[0001] This invention relates to the field of manned rocket technology, and in particular to a motor Sich rocket engine, namely the Zhenshun PD-6S manned rocket millimeter-wave radar navigation system. Background Technology

[0002] With the continuous development of aerospace technology, manned rocket technology has made great breakthroughs. Currently, manned rockets are usually used to transport lunar astronauts to lunar orbit so that they can land on the moon.

[0003] Existing manned rockets typically rely on radar navigation systems for real-time navigation during flight. During flight and start-up / shutdown, the rocket is prone to shaking. However, the radar navigation system lacks a damping component, causing its electrical components to vibrate and potentially damage. Therefore, a damping component is needed to cushion the vibrations of the radar navigation system's electrical components, preventing them from shaking and thus avoiding damage.

[0004] When encountering extreme weather such as rain, snow, or sandstorms during the use of manned rockets, radar navigation systems are required for real-time navigation. However, existing radar navigation systems do not have the ability to penetrate smoke and dust, which weakens their navigation capabilities in extreme weather conditions such as rain, snow, or sandstorms, thus reducing the effectiveness of radar navigation systems. Summary of the Invention

[0005] The purpose of this invention is to provide a millimeter-wave radar navigation system for the Motor Sich rocket engine, namely the Zhenshun PD-6S manned rocket, which solves the technical problem that existing radar navigation systems do not have the ability to penetrate smoke and dust, resulting in weak navigation capabilities in extreme weather conditions such as rain, snow, or sandstorms, thus reducing the effectiveness of radar navigation systems.

[0006] To achieve the above objectives, the present invention provides a millimeter-wave radar navigation system for the Motor Sich rocket engine, namely the Zhenshun PD-6S manned rocket, comprising a transmitter, a receiver, a signal processor, and a data processing module. The transmitter generates millimeter-wave signals and transmits them directionally. The receiver directionally receives signals reflected back from a target. The signal processor is connected to the receiver and performs filtering, noise reduction, and demodulation processing on the received signals. The data processing module is connected to the signal processor and converts the information processed by the signal processor into two-dimensional or three-dimensional images.

[0007] The Motor Sich rocket engine, namely the Zhenshun PD-6S manned rocket millimeter-wave radar navigation system, also includes a placement box, a protective plate, and fixing bolts. The placement box is detachably connected to the transmitter, the receiver, the signal processor, and the data processing module, and is located outside the transmitter, the receiver, the signal processor, and the data processing module. The protective plate is detachably connected to the placement box and is located on the upper surface of the placement box. The fixing bolts are detachably connected to the protective plate, abut against the placement box, and penetrate the protective plate.

[0008] The Motor Sich rocket engine, also known as the Zhenshun PD-6S manned rocket millimeter-wave radar navigation system, further includes a protective component for protecting the placement box.

[0009] The protective assembly includes a buffer block, a protective shell, a protective cover, and connecting bolts. The buffer block is used to absorb shocks from the placement box. The protective shell is located on the outside of the placement box. The protective cover is detachably connected to the protective shell and is located on the upper surface of the protective shell. The connecting bolts are detachably connected to the protective cover, abut against the protective shell, and penetrate the protective cover.

[0010] The buffer block includes a first slider, a first slide rail, and a connecting plate. The first slider is fixed to the lower surface of the placement box; the first slide rail is slidably connected to the first slider and is located on the lower surface of the first slider; the connecting plate is fixed to the lower surface of the first slide rail.

[0011] The buffer block further includes a second slider and a second slide rail. The second slider is fixed to the lower surface of the connecting plate; the second slide rail is slidably connected to the second slider and fixed to the inner side of the protective housing.

[0012] The buffer block further includes a horizontal spring and a vertical spring. The horizontal spring is fixed between the protective housing and the first slider; the vertical spring is fixed between the protective housing and the second slider.

[0013] This invention relates to a millimeter-wave radar navigation system for the Motor Sich rocket engine, specifically the Zhenshun PD-6S manned rocket. The millimeter-wave radar used in this invention has strong penetrating power, capable of penetrating clouds, fog, and darkness, enabling all-weather navigation. Simultaneously, the short wavelength of the millimeter-wave radar provides high resolution, allowing for precise target detection and positioning. Furthermore, millimeter-wave radar does not rely on optical signals and is unaffected by lighting conditions, while also possessing high anti-interference capabilities, thus improving the safety and reliability of the navigation system. In addition, the circuitry and components of the millimeter-wave radar are relatively simple, resulting in a low failure rate and high reliability. Therefore, the millimeter-wave radar navigation system can achieve precise control and navigation of the rocket and monitor its status in real time, thereby improving the effectiveness of the radar navigation system.

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] First embodiment:

[0023] Please see Figure 1 and Figure 2 ,in Figure 1 This is a schematic diagram of the overall structure of the Motor Sich rocket engine, namely the Zhenshun PD-6S manned rocket millimeter-wave radar navigation system, as described in the first embodiment. Figure 2 This is a cross-sectional view along the placement box 105. The present invention provides a millimeter-wave radar navigation system for the Motor Sich rocket engine, namely the Zhenshun PD-6S manned rocket, including a transmitter 101, a receiver 102, a signal processor 103, a data processing module 104, a placement box 105, a protective plate 106, and fixing bolts 107.

[0024] In this embodiment, the millimeter-wave radar used in this invention has strong penetrating power, capable of penetrating adverse weather conditions such as clouds, fog, and darkness, enabling all-weather navigation. Simultaneously, the short wavelength of millimeter-wave radar provides high resolution, enabling precise target detection and positioning. Furthermore, millimeter-wave radar does not rely on optical signals and is unaffected by lighting conditions, while also possessing high anti-interference capabilities, thereby improving the safety and reliability of the navigation system. In addition, the circuitry and components of millimeter-wave radar are relatively simple, resulting in a low failure rate and high reliability. Therefore, the millimeter-wave radar navigation system can achieve precise control and navigation of rockets and monitor their status in real time, thus improving the effectiveness of the radar navigation system.

[0025] The transmitter 101 generates millimeter-wave signals and transmits them directionally. The receiver 102 receives signals reflected back from the target directionally. The signal processor 103 is connected to the receiver 102 and performs filtering, denoising, and demodulation on the received signals. The data processing module 104 is connected to the signal processor 103 and converts the information processed by the signal processor 103 into a two-dimensional or three-dimensional image. The transmitter 101 generates millimeter-wave signals and transmits them directionally. The receiver 102 then receives the transmitted signals. The signal processor 103 processes the received signals using a "tripartite loss" algorithm, including filtering, denoising, and demodulation, to extract useful information. Finally, the data processing module 104 uses the "tripartite loss" algorithm to reconstruct the image from the information processed by the signal processor 103, converting the target information into a two-dimensional or three-dimensional image, thereby providing further information on the target's position and motion state.

[0026] Secondly, the placement box 105 is detachably connected to the transmitter 101, the receiver 102, the signal processor 103, and the data processing module 104, and is located outside the transmitter 101, the receiver 102, the signal processor 103, and the data processing module 104; the protective plate 106 is detachably connected to the placement box 105 and is located on the upper surface of the placement box 105; the fixing bolt 107 is detachably connected to the protective plate 106, abuts against the placement box 105, and penetrates the protective plate 106; the interior of the placement box 105 is a hollow structure, and the transmitter 101, the receiver 102, and the data processing module 104 are all connected. The signal processor 103 and the data processing module 104 are both placed inside the placement box 105. The protective plate 106 is placed above the placement box 105 and is tightened on the placement box 105 and the protective plate 106 using the fixing bolts 107. This limits and fixes the protective plate 106 above the placement box 105, thereby allowing the protective plate 106 to shield and protect the internal space of the placement box 105, preventing the transmitter 101, the receiver 102, the signal processor 103, and the data processing module 104 from moving out of the placement box 105.

[0027] When using the millimeter-wave radar navigation system of the Zhenshun PD-6S manned rocket, a type of Motor Sich rocket engine according to this embodiment, the transmitter 101, the receiver 102, the signal processor 103, and the data processing module 104 are placed inside the placement box 105 and fixed within the placement box 105. Then, the protective plate 106 is placed on top of the placement box 105, and the fixing bolts 107 are tightened in the threaded holes of the protective plate 106 and the placement box 105. This allows the protective plate 106 to shield and protect the internal space of the placement box 105, preventing the transmitter 101 and receiver 102 from being inside the placement box 105. After the signal processor 103 and the data processing module 104 are removed from the placement box 105, the transmitter 101 generates a millimeter-wave signal and transmits it directionally. The receiver 102 then receives the transmitted signal. The signal processor 103 processes the signal received by the receiver 102 using a "tripartite loss" algorithm, including filtering, noise reduction, and demodulation, to extract useful information. Finally, the data processing module 104 uses the "tripartite loss" algorithm to reconstruct the image from the information processed by the signal processor 103, converting the target information into a two-dimensional or three-dimensional image, thereby further providing the target's position and motion state.

[0028] In summary, the millimeter-wave radar used in this invention has strong penetrating power, capable of penetrating adverse weather conditions such as clouds, fog, and darkness, enabling all-weather navigation. Simultaneously, the short wavelength of millimeter-wave radar provides high resolution, allowing for precise target detection and positioning. Furthermore, millimeter-wave radar does not rely on optical signals and is unaffected by lighting conditions, while also possessing high anti-interference capabilities, thus improving the safety and reliability of the navigation system. Moreover, the circuitry and components of millimeter-wave radar are relatively simple, resulting in a low failure rate and high reliability. Therefore, the millimeter-wave radar navigation system can achieve precise control and navigation of rockets and monitor their status in real time, thereby improving the effectiveness of the radar navigation system.

[0029] Second embodiment:

[0030] Based on the first embodiment, please refer to Figures 3 to 5 , Figure 3 This is a schematic diagram of the adjustment component 201 of the millimeter-wave radar navigation system of the Motor Sich rocket engine, i.e., the Zhenshun PD-6S manned rocket, according to the second embodiment. Figure 4 This is a cross-sectional view along the vertical spring 210. Figure 5This is a cross-sectional view along the transverse spring 209. The present invention provides a millimeter-wave radar navigation system for the Motor Sich rocket engine, namely the Zhenshun PD-6S manned rocket, which also includes a protective component. The protective component includes a buffer block, a protective shell 201, a protective cover 202, and connecting bolts 203. The buffer block includes a first slider 204, a first slide rail 205, a connecting plate 206, a second slider 207, a second slide rail 208, a transverse spring 209, a vertical spring 210, a support block 211, a first telescopic rod 212, a fixing block 213, and a second telescopic rod 214.

[0031] In this embodiment, the protective component is located on the outside of the placement box 105. By providing the protective component, the protective component can protect the placement box 105.

[0032] The buffer block is used to dampen the shock of the placement box 105; the protective shell 201 is located on the outside of the placement box 105; the protective cover 202 is detachably connected to the protective shell 201 and is located on the upper surface of the protective shell 201; the connecting bolt 203 is detachably connected to the protective cover 202, abuts against the protective shell 201, and penetrates the protective cover 202; the protective shell 201 has a hollow internal structure; the protective cover 202 is placed on the protective shell 201; the protective shell 201 and the protective cover 202 are connected by the connecting bolt 203; the connecting bolt 203 can be tightened or loosened on the protective shell 201 and the protective cover 202, so that the protective cover 202 can be installed or removed above the protective shell 201, thereby allowing the protective cover 202 to shield and protect the internal space of the protective shell 201.

[0033] Secondly, the first slider 204 is fixedly mounted on the lower surface of the placement box 105; the first slide rail 205 is slidably connected to the first slider 204 and located on the lower surface of the first slider 204; the connecting plate 206 is fixedly mounted on the lower surface of the first slide rail 205; the first slider 204 has a sliding groove, and the first slide rail 205 cooperates with the sliding groove of the first slider 204, so that the sliding groove of the first slider 204 can slide laterally above the first slide rail 205, thereby driving the placement box 105 to move laterally above the connecting plate 206.

[0034] Furthermore, the second slider 207 is fixedly mounted on the lower surface of the connecting plate 206; the second slide rail 208 is slidably connected to the second slider 207 and fixedly mounted on the inner side of the protective housing 201. The second slider 207 has a slide groove, and the second slide rail 208 cooperates with the slide groove of the second slider 207, so that the slide groove of the second slider 207 can slide longitudinally above the second slide rail 208, thereby driving the connecting plate 206 to move longitudinally within the protective housing 201.

[0035] Meanwhile, the horizontal spring 209 is fixed between the protective housing 201 and the first slider 204; the vertical spring 210 is fixed between the protective housing 201 and the second slider 207. The horizontal spring 209 and the vertical spring 210 are disposed between the protective housing 201 and the placement box 105. Both the horizontal spring 209 and the vertical spring 210 are equipped with dampers. When the horizontal spring 209 or the vertical spring 210 extends or retracts, the dampers on the horizontal spring 209 or the vertical spring 210 generate a damping force that prevents the horizontal spring 209 or the vertical spring 210 from extending or retracting, thereby causing the horizontal spring 209 or the vertical spring 210 to... The vertical spring 210 will not continuously extend and sway. When the groove of the first slider 204 slides laterally on the first slide rail 205, the horizontal spring 209 will extend and retract. Since the horizontal spring 209 has a self-restoring function, it will buffer the lateral sliding of the first slider 204 on the first slide rail 205. When the groove of the second slider 207 slides longitudinally on the second slide rail 208, the vertical spring 210 will extend and retract. Since the vertical spring 210 has a self-restoring function, it will buffer the longitudinal sliding of the second slider 207 on the second slide rail 208.

[0036] In addition, the support block 211 is fixed to the upper surface of the connecting plate 206; the two ends of the first telescopic rod 212 are respectively connected to the output end of the support block 211 and the first slider 204. The first telescopic rod 212 is located between the support block 211 and the first slider 204. When the slide groove of the first slider 204 slides laterally above the first slide rail 205, the first telescopic rod 212 will extend and retract. At this time, the support block 211 can restrict the extension and retraction position of the first telescopic rod 212.

[0037] Finally, the fixing block 213 is fixed inside the protective housing 201; the two ends of the second telescopic rod 214 are respectively connected to the output end of the fixing block 213 and the second slider 207. The second telescopic rod 214 is located between the fixing block 213 and the second slider 207. When the slide groove of the second slider 207 slides longitudinally above the second slide rail 208, the second telescopic rod 214 will extend and retract. At this time, the fixing block 213 can restrict the extension and retraction position of the second telescopic rod 214.

[0038] When using the Zhenshun PD-6S manned rocket millimeter-wave radar navigation system, which is a motor Sich rocket engine according to this embodiment, the protective cover 202 is placed on the protective shell 201 during use. Then, the connecting bolts 203 are tightened on the protective shell 201 and the protective cover 202, allowing the protective cover 202 to be installed above the protective shell 201. This allows the protective cover 202 to shield and protect the internal space of the protective shell 201. During the flight and start-up / shutdown of the manned rocket, the rocket will shake, causing the placement box 105 to shake within the protective shell 201. When the placement box 105 shakes laterally within the protective shell 201, the groove of the first slider 204 will slide laterally above the first slide rail 205, thereby causing the first telescopic rod 212 to extend and retract, which in turn causes the lateral spring 209 to extend and retract. Since the lateral spring 209 has a self-recovering function... The horizontal spring 209 buffers the lateral movement of the placement box 105 within the protective housing 201. When the placement box 105 wobbles longitudinally within the protective housing 201, the groove of the second slider 207 slides longitudinally above the second slide rail 208, thereby driving the second telescopic rod 214 to extend and retract, which in turn drives the vertical spring 210 to extend and retract. Since the vertical spring 210 has a self-restoring function, it buffers the vertical movement of the placement box 105 within the protective housing 201. By using the horizontal spring 209 and the vertical spring 210 to buffer the lateral and vertical movement of the placement box 105 within the protective housing 201, the wobbling of the placement box 105 within the protective housing 201 is buffered, thus preventing damage to the electrical components inside the placement box 105 caused by the shaking along with the drone.

[0039] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
