航天模型有什么用?

发布时间:2023-02-25 来源:http://www.quanyimoxing.com/

航天模型,顾名思义是仿航天器外形制作的一种可回收模型,隶属于航空航天模型,是供运动用的一种不载人的飞行器,其动力为模型火箭发动机,即一种微型固体火箭发动机。下面大型航天模型厂家为您分析:
The aerospace model, as its name implies, is a recoverable model made by imitating the shape of spacecraft, belonging to the aerospace model. It is a kind of unmanned aircraft for operation. Its power is the model rocket engine, which is a kind of micro solid rocket engine. The following large-scale aerospace model manufacturers will analyze for you:
由于航天模型多呈火箭状,故通称模型火箭。换句话说,模型火箭是指不利用气动升力去克服重力,而是靠模型火箭发动机推进升空的一种航空模型;它装有使之安全返回地面的以便再次飞行的回收装置;为确保安全,它的结构部件必须由非金属材料制成。
Because space models are mostly rocket-like, they are generally called model rockets. In other words, model rocket refers to an aviation model that does not use aerodynamic lift to overcome gravity, but uses model rocket engine to propel and lift off; It is equipped with a recovery device to make it return to the ground safely for flight again; To ensure safety, its structural components must be made of non-metallic materials.
模型火箭虽小,然而它要靠模型火箭发动机推进才能在大气中飞行。因此,设计和制做模型火箭需要多方面的知识,如空气动力学、火箭飞行力学等。
Although the model rocket is small, it needs to be propelled by the model rocket engine to fly in the atmosphere. Therefore, the design and manufacture of model rockets require a variety of knowledge, such as aerodynamics, rocket flight mechanics, etc.

要研究模型火箭在空气中飞行的稳定性和空气对它的阻力;要分析火箭的飞行轨迹,计算它的飞行高度;有条件时,还可以对模型火箭进行风洞试验,确定火箭佳外形;进行模型火箭发动机静态性能测试试验,测量推力和工作时间,计算总冲量。
To study the stability of the model rocket in the air and the resistance of the air to it; To analyze the flight path of the rocket and calculate its flight altitude; If conditions permit, the model rocket can also be tested in the wind tunnel to determine its good shape; Conduct static performance test of model rocket engine, measure thrust and working time, and calculate total impulse.
在发达国家的一些高等学校里,在理工科有关的课程上,甚至一些中学的物理课上,教师们经常以模型火箭作为讲课的题材,并在此基础上指导学生开展一些课题研究和模型火箭的制作。
In some colleges and universities in developed countries, teachers often use model rockets as the subject matter of lectures in courses related to science and engineering, and even in physics classes in some middle schools, and guide students to carry out some project research and model rocket production on this basis.
