RANGE
The new E190-E2 has a range of 400 nm
higher than that of the E190, which also
means, if the operator opts, 2 tons more
in the maximum takeoff weight.

LANDING GEAR


STABILIZERS
The stabilizers were redesigned in order to obtain
aerodynamic gains and better performance. The
vertical stabilizer is 26% smaller as compared with
that of the E190, allowing better aerodynamic
resultant and weight reduction.


the previous model, but a series of project
improvements allowed reducing the weight
in around 2 tons.

FUSELAGE
The E190-E2 has the same fuselage of
the previous model but a series of project

CONSUMPTION
The E190-E2 consumes 16% less
than the previous model, and
11% proceed from the engine,
3.5% from the aerodynamic
improvements and 1.5% from
the new fly-by-wire.

ENGINES
Although commercial aviation aeronautical
projects still were viable from the commercial
point of view, the current engine generation
led the main competitors to find a competitive
advantage in the remotorization of their products.
In the E2, Embraer installed Pratt & Whitney
PW1900G engines of the PurePower series.
The new engine has the fan axis separated from
the low pressure compressor and the turbine.
Each mounted on a module, which operates at
maximum performance speed. Moreover, the
fan rotates in opposite sense to the compressor,
improving efficiency. The engine has an axial
compressor, a geared fan, a three-stage low-
pressure compressor, eight-stage high pressure
compressor and 12:1 by-pass ratio. With the new
technologies, the engine consumes 24% less fuel
than the previous generation, affirms Embraer.

The landing gear had to be
raised and reinforced, which
demanded redesigning the
bay of the main landing gear,
which became retractable
into the fuselage.
