Embraer rolls out E195-E2 jet


Embraer has rolled out the largest member of its E-jet E2 single aisle passenger jet family, the E195-E2.

The second generation E-jet E2 family aircraft features new optimized wing and a new engine that enable a double digit improvement in fuel economy compared to the first generation that entered service in 2004.

The E195-E2 wing has the highest aspect ratio (one measure of aircraft fuel efficiency) among single-aisle jets.

The first member of the E2 family, the E190 had completed its maiden flight in May 2016. The three member E2 family is exclusively powered by the Pratt & Whitney's PW1000G Geared Turbofan engines.

The E2 family's landing gear was redesigned along with new wing, fly-by-wire controls, and vertical and horizontal stabilizers to improve fuel efficiency.

The E195 E2 has a Max. take off weight of 60,700 kg (133,821 lb), Maximum landing weight of 54,000 kg  (119,050 lb) and a payload capacity of 16,150 kg (35,506 lb).

The E195-E2 has three additional rows of seats, when compared to the current generation E195, and it can be configured with 120 seats in two classes of service, or up to 146 in a single class. The aircraft also has a significant increase in range of 450 nautical miles, which allows trips of up to 2,450 nautical miles.

The aircraft has a dedicated wing, with the highest aspect ratio among single-aisle jets, increasing fuel efficiency. In addition to a more balanced specification, Embraer applied over 17 million hours of flight experience on today's E-Jet fleet of over 1,300 units to come up with the optimal E2 design.For example, being designed with an intelligent combination of materials, the E195-E2 can carry 10% more passengers than a direct competitor and still have the same weight.

“We introduced in the proven E-Jets platform all new technologies that would add value to customers. One example is the fourth generation of fly-by-wire, which allowed a 20% reduction of the empennage area, minimizing drag and weight,” explained Luís Carlos Affonso, COO, Embraer Commercial Aviation.

“The airplane will save up to 24% in fuel and 20% in maintenance costs per seat, when compared to the current E195. A portion of these savings will be achieved with the new engine technology, but the greatest competitive advantage of the E195-E2 lies in the optimization of its structure and of its various systems.”

Embraer will use two aircraft for the E195-E2 certification campaign. The first prototype will be used for the aerodynamic and performance tests. The second prototype, which will also make its inaugural flight by the end of this year, will be used for the validation of maintenance tasks and of the interior.

Max operating speed is Mach 0.82, while its service ceiling is 41,000 ft.

It requires a minimum runway length of 1,970 m (6,463 ft) for take off and 1,420 m (4,659 ft) for landing. The aircraft is scheduled to enter service in the first half of 2019, and will directly compete with the Bombardier CS100.
