| The Embraer ERJ family (for Embraer Regional Jet) are regional jets designed and produced by the Brazilian aerospace company Embraer. The family includes the ERJ 135 (37 passengers), ERJ 140 (44 passengers), and ERJ 145 (50 passengers), as well as the Legacy 600 business jet and the R-99 family of military aircraft. |
The ERJ 145 was designed for a perceived new market for regional jet aircraft, where the increased speed, comfort and passenger appeal would outweigh the inherent fuel economy of the turboprop aircraft which were in service and in development.
The 45–48 seat EMB 145, nicknamed Amazon, was launched at the Paris Air Show in 1989 as an 18-foot (5.5 m) stretch of the EMB 120 Brasilia developed for US$150 million plus $50 million for training and marketing, one third the cost of the cancelled Short Brothers FJX project. Its $11 million unit cost would have been $3 million less than the Canadair CRJ. The jet was anticipated to be able to travel at 400 knots (740 km/h; 460 mph), equipped with the CFE738, Lycoming ALF 502 or Rolls-Royce/Allison AB580 turbofan engines, with the model to be selected in the summer of 1989. It was targeted for a late 1992 introduction with six produced, then ramping to 60 per year by 1995. It aimed for half of a market for 1,000 aircraft with break-even after twelve years with 400 sold.[

Regional airliner. In service since 1996. Renamed from EMB-145 to signify its regional jet role. Based on stretched jet-powered studies of the EMB-120 Brasilia. Built as ER, standard version and LR slightly more powerful extended range version with additional fuel tank. Also developed into a shorter ERJ-140 version. Military surveillance versions EMB-145SA and EMB-145RS for Brazil Air Force. The E145 is a member of the ERJ Family of aircraft.
In March 1991, a revised configuration started wind tunnel testing: the quarter chord wing sweep increased to 22.3°.
In early 1990, no engine supplier willing to share the risk of the $250 million development was yet selected.[6] The Allison GMA3007 (later renamed the Rolls-Royce AE 3007).
