Description

Technical Field

[0001] This utility model relates to the field of teaching model technology, and in particular to a teaching and experimental model. Background Technology

[0002] In current education and research fields, rocket models are undeniably important teaching tools for understanding aerospace technology, physics principles, and engineering applications. However, most existing educational rocket models are limited to static displays. These models can only present the rocket's external structure in a static form, failing to simulate the dynamic processes of actual launch, flight control, and recovery. This limitation significantly restricts the depth and breadth of rocket model application in education and experimentation.

[0003] Specifically, static rocket models fail to allow students and researchers to intuitively experience key aspects such as the immense thrust during launch, attitude adjustments during flight, and precise control during recovery. These dynamic functions are indispensable for understanding rocket working principles and mastering the essence of aerospace technology. Therefore, existing static rocket models cannot meet the needs of educators and researchers for more interactive and hands-on experiences, nor can they fully stimulate students' interest in exploration and their innovative abilities. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the technical problem of this utility model is to provide a teaching rocket model that can simulate the dynamic processes of rocket launch, flight control and recovery, so as to help students and researchers to understand the working principle of rockets and aerospace technology.

[0005] Technical solution: A teaching and experimental model, including a rocket fuselage, a nose wing at the nose, and an engine and tail wing at the tail. The nose of the fuselage is divided into a bullet-shaped semi-enclosed cavity structure. The middle section and tail section are barrel-shaped frames made of woven wire. A mid-frame plate is integrated in the lower middle part of the fuselage. Servo motors are installed on the nose and mid-frame plate to control the movement of the nose wing, tail wing, and engine, respectively. A power supply battery is provided on the mid-frame plate.

[0006] Furthermore, it is particularly preferred that the engine includes a support arm located at the tail, with a motor located at the upper center of the support arm and blades mounted on the motor.

[0007] Furthermore, it is particularly preferred that the support arm is connected to the fuselage via a pin, one end of the support arm is connected to a first control lever, and the end of the first control lever away from the support arm is connected to the rotating arm of one of the servo motors.

[0008] Furthermore, it is particularly preferred that the engine comprises an upper engine and a lower engine with identical structures, wherein the angle between the support arm of the upper engine and the support arm of the lower engine is 90 degrees.

[0009] Furthermore, it is particularly preferred that two tail fins are symmetrically arranged along the outer side of the tail, and the tail fins are movably connected to the fuselage via pins. One end of the tail fin is connected to a second control lever, and the end of the second control lever away from the tail fin is connected to the rotating arm of one of the servo motors.

[0010] Furthermore, it is particularly preferred that two nose wings are symmetrically arranged along the outer side of the nose, and the nose wings are movably connected to the fuselage via pins. One end of the nose wing is connected to a third control lever, and the end of the third control lever away from the nose wing is connected to the rotating arm of one of the servo motors.

[0011] Furthermore, it is particularly preferred that the motor is a high-speed brushless motor.

[0012] Compared with the prior art, this utility model has the following advantages: This utility model uses the fuselage, nose wing, engine and tail wing to form a simple rocket model. By controlling the direction of the engine and nose and tail wing with servo motors, the rocket model can be launched, controlled in flight and recovered and landed. It can not only show the internal structure of the rocket intuitively, but also observe the launch and recovery of the rocket, which helps students and researchers understand the working principle of rocket.

Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0019] like Figure 1 The teaching and experimental model shown includes a rocket fuselage 1, which consists of three parts: a nose section 11, a mid-section 12, and a tail section 13. The nose section 11 is a bullet-shaped semi-enclosed cavity structure made of plastic. The mid-section 12 and tail section 13 are barrel-shaped frames woven from ring-shaped and straight iron wires. This sparse structure reduces the weight of the rocket model and facilitates takeoff. Two nose wings 4 and two tail wings 5 ​​are provided, symmetrically positioned on the nose section 11 and symmetrically on the tail section 13. The tail section 13 also houses engines 7a and 7b that drive the rocket model's ascent and descent. A center frame 2 is integrated in the lower part of the fuselage 1. Servo motors 31, 32, and 33 are installed in the cavity of the nose section 11 and on the center frame 2, respectively. Servo motors 31, 32, and 33 control the movement of the nose wings 4, tail wings 5, and engines 7a and 7b. A battery 6 providing power is also located on the center frame 2. This model has a simple structure, allowing students to clearly observe the internal architecture of the rocket. The rocket model is powered by a drive unit consisting of battery 6 and engines 7a and 7b. The direction of the rocket model is controlled by the cooperation of servo motors 31, 32, and 33 with nose fins 4 and tail fins 5. This teaching model not only intuitively demonstrates the composition of the rocket but also deepens students' understanding of rocket principles and improves teaching quality by simulating rocket flight control and recovery.

[0020] In one specific embodiment, the engine includes two structurally identical upper engines 7a and 7b, and lower engines 7a and 7b, as detailed in the following reference. Figure 1 and Figure 2The rocket model comprises a support arm 71, a motor 72, and a propeller 73. The two support arms 71 are respectively mounted on the tail 13 via pins. A motor 72 is mounted on the upper center of each support arm 71. The motor 72 is preferably a high-speed brushless motor. Propeller blades 73 are mounted on the shaft of each motor 72. It should be noted that the angle between the support arm 71 of the upper engine 7a and the support arm 71 of the lower engine 7b is 90 degrees. One end of each support arm 71 is connected to a first control lever 81. The end of the first control lever 81 away from the support arm 71 is connected to a servo motor 31. The servo motor 31 can control the deflection of the support arm 71, thereby controlling the direction of the rocket model.

[0021] Additionally, in specific embodiments, refer to Figure 3 and Figure 4 Two tail fins 5 are movably connected to the fuselage 1 via pins. One end of each tail fin 5 is connected to a second control lever 82, and the end of the second control lever 82 away from the tail fin 5 is connected to the rotating arm of one of the servo motors 32. The deflection of the tail fins 5 can be controlled by the servo motor 32 and the second control lever 82, thereby achieving directional control of the rocket model. Similarly, two nose fins 4 are movably connected to the fuselage 1 via pins. One end of each nose fin 4 is connected to a third control lever 83, and the end of the third control lever 83 away from the nose fin 4 is connected to the rotating arm of one of the servo motors 33, which is installed in the cavity of the nose fin 11. The deflection of the nose fins 4 can be controlled by the servo motor 33 and the third control lever 83, thereby achieving directional control of the rocket model.

[0022] Finally, it should be noted that a control motherboard is integrated on the central frame 2. This control motherboard is connected to the motor 72, servo motors 31, 32, and 33, and the battery 6. The motherboard integrates a wireless control module, which can control the ascent and descent of the rocket model wirelessly.

[0023] This model combines the characteristics of static and dynamic rocket models. Through dynamic flight, students and researchers can intuitively experience the enormous thrust of a rocket during launch, the attitude adjustment during flight, and the precise control during the recovery phase, fully stimulating students' interest in exploration and their innovative abilities.
