Embraer ERJ-170

In the early ’90s, regional aircraft with turbofan engines began to significantly push jet engines. The comfort provided by the new generation turboprop aircraft was required to add greater speed to compete with jet aircraft used on short-haul long-haul lines. However, a genuine revolution in the construction of such aircraft occurred in 1992, when the Canadian Bombardier group introduced its 50-seat CRJ 100. Soon after, the Brazilian company Embraer quickly managed to break into the market, having managed to outrun Canadian competitors in the market of 50 local aircraft by the number of orders. To date, Embraer is the 4th largest civil aircraft manufacturer in the world in terms of personnel (after Boeing, Airbus, and Canadian Bombardier) and the third in the number of aircraft built annually (after Boeing and Airbus). The breakthrough into the competitive market of Embraer regional aircraft from the city of São José dos Campos (São Paulo state) was praised by experts as an unexpected, but the obvious and logical success of Brazilian aircraft manufacturers.

ERJ-170 is a mid-range passenger aircraft for local airlines, developed by the Brazilian company Embraer. Embraer E-Jet – a family of twin-engine narrow-body medium-range passenger aircraft. Includes 4 modifications: E-170, E-175, E-190 and E-195. The E-Jet family includes the regional Embraer 170, 175. 190 and 195 aircraft designed to carry from 70 to 110 passengers. Improved design, improved specifications, operational efficiency, low levels of harmful emissions into the atmosphere, and a spacious cabin are the main distinguishing features of the aircraft. The commonality of the designs of the E-Jet family can significantly reduce the cost of spare parts, the cost of equipping simulators and training personnel, as well as the cost of maintenance and repair. The 170th model is adapted for 70 – 80 passengers, the family also includes Embraer 175 (78 – 84 passengers), Embraer 190 (98 passengers), and Embraer 195 (108 passengers).

The aircraft is a new development of Embraer in the class with increased passenger capacity compared to ERJ-135/140/145. The firms involved in the development of the aircraft: General Electric (CF34-8E / 10E turbofan engines), Hamilton Sundstrand (tail development), Honeywell (Primus Epic avionics), Kawasaki, Latecoere, Liebherr, Gamesa, Sonaca (various parts of the fuselage), Parker Hannifin (hydrodynamics and fuel system). Work on the aircraft began in 1998. In 1999, Embraer launched a new program for the construction of civil aircraft of the E-170/190 family, designed for 70-118 passengers. The aircraft was first presented on February 11, 1999, and shown in June 1999 at the Paris Air Show. The first flight took place on February 9, 2002. Serial production started at the end of 2002. The release in 2003 of the 70-seat ERJ-170 model marked the birth of the next generation of commercial airliners – more spacious and meeting the requirements of national airlines. The cost of the aircraft is estimated at 21 million dollars. On March 17, 2004, in Warsaw, the first commercial flight was E 170, and, according to the results of 2004, 46 aircraft were delivered to different airlines.
