Example Embodiment

[0025] Examples include:

[0026] like figure 1 , a model rocket with a good aerodynamic shape, which is characterized in that the shape curve of the nose cone 1 adopts the von Karman curve, and the surface of the rocket body 4 is wrapped with a hermetic lightweight skin, and the aspect ratio is 12.5, so the surface has a smooth flight trajectory Good, the attitude is stable during flight.

[0027] In another embodiment, as figure 2 , image 3 , a vector tail 5, which is characterized in that: the vector is detachable, and under the control of the steering gear 7, the tail 5 can be rotated at a certain angle through the control of the digital steering gear 7 to change the aerodynamic layout of the model rocket, thereby achieving the change The purpose of the flight path.

[0028] In another embodiment, as Figure 4 , there is a buckle 8 at the bottom of the nose cone 1, and a chute 9 at the top of the control cabin. The head cone 1 and the arrow body 4 are fixed by a qui...

Abstract

The invention discloses a novel model rocket. The whole arrow is composed of, from top to bottom, a nose cone, a control cabin, an arrow body, a tail fin and an engine. In structural design, the modelrocket innovates with the use of vector, removable tail fins. The nose cone is made of PLA material, printed in 3D and designed with the von Karman curve of aerospace, which ensures the minimum air drag of the arrow during flight, and the control circuits are integrated in the control module. The main structure of the arrow body is made of wood, and the carbon tube is used as the supporting framework to increase the stability of the arrow body and reduce the weight of the arrow. The control cabin is connected with the nose cone by a quick disassembly structure, so that the arrow body can be quickly assembled. The invention can ensure the stability of the model rocket body to the maximum extent, realize the controllability of the flight trajectory, and reach the designated target point inthe air. At the same time, the model rocket has an excellent aerodynamic configuration, can reduce the flight resistance, and thus achieves a higher flight height.

Description

technical field [0001] The invention relates to the field of model rockets, in particular to the design of a novel model rocket structure. Background technique [0002] The so-called model rocket refers to a miniature rocket similar to a large rocket, which has the functions of ignition launch, air flight and parachute recovery like a real rocket. A model rocket is a model with aerospace characteristics. No matter it is the model airplane competition that students often participate in, or some performances, you can see the figure of the model rocket, and the overall structure of the model rocket plays a vital role in the stability and flight trajectory of the rocket, but in the existing In the current technology, the overall structure of the model rocket has one or more of the following disadvantages: [0003] 1. The overall structural strength and stability of the model rocket are insufficient, and the rocket body structure is difficult to withstand the thrust of multiple...
