ERJ45超远程运输机原名为EMB145超远程运输机,是巴西航空工业公司最新研制的第一种涡扇式支线客机。这架飞机是在EMB—120“巴西利亚”的基础上研制出来的,所以,两种飞机有很高的通用性。但新机采用中涵道比涡扇发动机,机翼重新设计并装有翼梢小翼,两台发动机采用尾吊方式。飞机机身在EMB—120基础上有所加长,以适应载客量增加的需要。 The ERJ45 ultra long-range transport aircraft, formerly known as the EMB145 ultra long-distance transport aircraft, is the first turbofan regional feeder aircraft developed by Embraer. The aircraft was developed on the basis of the EMB-120 “Brasilia”, so the two aircraft are highly versatile. However, the new machine adopts a medium-pass ratio turbofan engine, the wing is redesigned and equipped with wingtip small wings, and the two engines adopt tail suspension. The aircraft fuselage has been extended on the basis of EMB-120 to meet the need for increased passenger capacity.
