Bombardier, a Canadian firm, builds the wings for its new CSeries of regional jets in Belfast.

庞巴迪公司（加拿大一家飞机生产商）在贝尔法斯特为新型C系列的支线飞机制造机翼。

At only 3,600 feet or 1,100 meters long, not even a small regional jet like a CRJ 700 could land there.

只有 3,600 英尺或 1, 100 米长， 即使是像 CRJ 700 这样的小型支线喷气式飞机也无法降落在那里。

In addition to cars, Toyota is part owner of Mitsubishi Aircraft Corp, which will be creating a regional jet within the next year.

除汽车外，丰田还是三菱飞机公司的部分所有者，该公司将在明年制造一架支线喷气式飞机。

Some smaller aircraft have engines mounted  on the fuselage tail, including, for example, the Embraer ERJ family and  the COMAC ARJ21 regional jet.

一些较小的飞机在机身尾部安装了发动机，例如，Embraer ERJ 系列和 COMAC ARJ21 支线喷气式飞机。

Today, you can mostly find aft-mounted  engines on private business jets and small regional jets like the CRJ series. But why did tail-mounted engines go out of fashion for commercial jets in  favor of the under-wing engine design?

今天，您可以在私人公务机和小型支线飞机（如 CRJ 系列）上找到后置发动机。但是，为什么尾部安装的发动机在商用喷气机中过时了，转而采用翼下发动机设计？
