大型航天模型作为一种可回收模型本身如何?

发布时间:2022-12-21 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,受到多个人群的喜爱。那么你知道大型航天模型作为一种可回收模型本身如何吗?下面小编为您简单讲解几句。
The space model, as its name implies, is a recyclable model made by imitating the shape of the spacecraft and is loved by many people. Do you know how the large-scale aerospace model itself is a recyclable model? Here is a brief explanation for you.
大型航天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。由于航天模型多呈火箭状,故通称模型火箭。
Large space model belongs to aerospace model, which is a kind of unmanned aircraft for operation. Its power is model rocket motor, that is, a micro solid rocket motor. As most space models are rocket shaped, they are generally called model rockets.
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,它的结构部件须由非金属材料制成。
In other words, the model rocket refers to an aviation model that does not use aerodynamic lift to overcome gravity, but is propelled by the model rocket engine; It is equipped with a recovery device to enable it to return to the ground safely for re flight; 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。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。
Although the model rocket is small, it can fly in the atmosphere only when it is propelled by the model rocket engine. Therefore, the design and manufacture of model rockets require knowledge of many aspects, such as aerodynamics, rocket flight mechanics, etc. The stability of the model rocket in the air and the air resistance to it should be studied; To analyze the flight path of the rocket and calculate its flight altitude; When conditions permit, wind tunnel tests can also be carried out on the model rocket to determine the best shape of the rocket; Carry out 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, in the courses related to science and engineering, and even in the physics classes in some middle schools, teachers often use model rockets as the subject matter of lectures, and on this basis guide students to carry out some research projects and make model rockets.
