Regional Airliner

DESCRIPTION:
With turboprop-powered aircraft becoming more unpopular with passengers, EMBRAER of Brazil was one of the first companies to develop a turbofan-powered commuter aircraft. EMBRAER sought to maximize commonality with its EMB-120 aircraft in order the miniumize costs. The EMB-145, which was later redesignated the ERJ-145 for EMBRAER Regional Jet, originally used the straight-wings of the EMB-120 as well as a stretched version of the EMB-120 fuselage. Later redesigns evolved to include swept wings with supercritical airfoils allowing improved performance. The engine location also moved from above the wings to below the wings and finally to the tail before the design was finally frozen. Deliveries of the ERJ-145 began in 1996 to operators in Brazil, Europe, Australia, and the US. The basic design has proven such a resounding success that two shortened models, the ERJ-135 and ERJ-140, as well as military models have been produced. The success of the ERJ-145 family has firmly cemented EMBRAER as one of the dominant manufacturers of regional jets.
