航天模型，顧名思義是仿航天器外形制作的一種可回收模型，隸屬于航空航天模型，是供運(yùn)動(dòng)用的一種不載人的飛行器，其動(dòng)力為模型火箭發(fā)動(dòng)機(jī)，即一種微型固體火箭發(fā)動(dòng)機(jī)。下面大型航天模型廠家為您分析：

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狀，故通稱模型火箭。換句話說，模型火箭是指不利用氣動(dòng)升力去克服重力，而是靠模型火箭發(fā)動(dòng)機(jī)推進(jìn)升空的一種航空模型；它裝有使之安全返回地面的以便再次飛行的回收裝置；為確保安全，它的結(jié)構(gòu)部件必須由非金屬材料制成。

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.

模型火箭雖小，然而它要靠模型火箭發(fā)動(dòng)機(jī)推進(jìn)才能在大氣中飛行。因此，設(shè)計(jì)和制做模型火箭需要多方面的知識(shí)，如空氣動(dòng)力學(xué)、火箭飛行力學(xué)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氣中飛行的穩(wěn)定性和空氣對(duì)它的阻力；要分析火箭的飛行軌跡，計(jì)算它的飛行高度；有條件時(shí)，還可以對(duì)模型火箭進(jìn)行風(fēng)洞試驗(yàn)，確定火箭佳外形；進(jìn)行模型火箭發(fā)動(dòng)機(jī)靜態(tài)性能測(cè)試試驗(yàn)，測(cè)量推力和工作時(shí)間，計(jì)算總沖量。

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.

在發(fā)達(dá)國(guó)家的一些高等學(xué)校里，在理工科有關(guān)的課程上，甚至一些中學(xué)的物理課上，教師們經(jīng)常以模型火箭作為講課的題材，并在此基礎(chǔ)上指導(dǎo)學(xué)生開展一些課題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.

航模已經(jīng)超出了航空航天科學(xué)家研究的狹窄范圍，成了航空航天和飛行愛好者的一種學(xué)習(xí)手段。您如果對(duì)大型航天模型有興趣，可以隨時(shí)來我們網(wǎng)站http://www.z4358.cn進(jìn)行咨詢！
