Novel model rocket

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...

AI Technical Summary

Problems solved by technology

[0003] 1. The overall structural strength and stability of the model rocket is insufficient, and the rocket body structure is difficult to withstand the thrust of multiple engines, which may easily cause damage to the rocket body

[0004] 2. The overall aerodynamic layout of the model rocket is poor, and it is easy to produce flight trajectory deviation during flight

[0005] 3. The tail of the model rocket is fixed, so it is impossible to change the flight trajectory, so it is impossible to realize the orbit change flight in the air

[0006] 4. The overall material of the model rocket is made of non-degradable plastic, which is easy to cause environmental pollution
