模型火箭同航空模型一樣,是一項(xiàng)國(guó)際性的體育競(jìng)技項(xiàng)目,同時(shí),也是一項(xiàng)深受廣大青少年所喜愛的科普活動(dòng)。

The model rocket, like the aviation model, is an international sports event. At the same time, it is also a popular science activity loved by the majority of young people.

模型火箭在本世紀(jì)五十年代起源于美國(guó),隨后傳歐洲各國(guó),并得到迅速發(fā)展。

Model rocket originated in the United States in the 1950s, then spread to European countries, and developed rapidly.

1959年國(guó)際航空聯(lián)合會(huì)(FAI)正式確認(rèn)模型火箭為國(guó)際性的體育比賽項(xiàng)目,并制訂了具體的競(jìng)賽規(guī)則,國(guó)際性比賽于1966年5月在前捷克斯洛伐克舉行。

In 1959, the international aviation Federation (FAI) officially recognized the model rocket as an international sports event, and formulated specific competition rules. The first international competition was held in May 1966 in the former Czechoslovakia.

我國(guó)的模型火箭運(yùn)動(dòng)發(fā)展較晚,但模型火箭在我國(guó)受到越來(lái)越多青少年的喜愛。

The development of model rocket in China is relatively late, but model rocket is loved by more and more teenagers in China.

在營(yíng)動(dòng)航天?火箭課堂，同學(xué)們跟隨著小焦老師的介紹深入了解火箭相關(guān)的知識(shí)。

In the classroom of Yingdong Aerospace? Rocket, the students follow teacher Jiao's introduction and have a deep understanding of rocket related knowledge.

并設(shè)計(jì)、制作了模型火箭。

The model rocket is designed and manufactured.

課堂上，小焦老師向同學(xué)們介紹了解模型火箭及模型火箭運(yùn)動(dòng)，帶領(lǐng)大家了解模型火箭的結(jié)構(gòu)及各部分之間的功能。

In class, Xiao Jiao introduced the model rocket and its movement to the students, and led them to understand the structure of the model rocket and the function of each part.

要求大家熟悉模型火箭飛行方面的基本知識(shí)、掌握模型火箭的總體布局和零部件設(shè)計(jì)，并且要知道工程設(shè)計(jì)的基本步驟。

We should be familiar with the basic knowledge of model rocket flight, master the overall layout and parts design of model rocket, and know the basic steps of engineering design.

模型火箭，顧名思義是仿航天飛行器外形制作的一種在大氣層中飛行的可回收模型，隸屬于航空模型；

Model rocket, as the name suggests, is a recoverable model of flying in the atmosphere made by imitating the shape of space vehicle, which belongs to the aviation model;

它的動(dòng)力是模型火箭發(fā)動(dòng)機(jī)，是一種微型固體火箭發(fā)動(dòng)機(jī)；

Its power is model rocket motor, which is a kind of micro solid rocket motor;

它裝有使之返回地面的以便再次飛行的回收裝置。

It is equipped with a recovery device to make it safely return to the ground so that it can fly again.
