THE SECOND
GENERATION’S
EVOLUTION
The main changes in the first member of the new family,
the E190-E2, which will begin its operations with the
Norwegian company Widerøe, Scandinavia’s largest
regional airline
LOWER NOISE
The new engines
together with the new
wing design allowed
reducing noise by 60%.The E2 family was given new wing
designs, with each member having a
specific project, improving aerodynamic
efficiency. Contrary to what could be
supposed, which means, opting for
a composite material wing, Embraer
has developed fully metallic wings.
According to the manufacturer, the
advantage is in the good performance of
the technology for this kind of aircrafts,
as well as in the lower maintenance costs
and time. In the case of the E190-E2, the
wing passed to 33.7 meters compared to
the 28.7 meters of the E190. The wing
was also given structural improvements
to allow the installation of the new
engines with 185.42 cm diameter.FULL FLYBYWIRE
Contrarily to the first generation models, the current
E190-E2 has full fly-by-wire. The main difference
is that the first project maintained a conservative
concept; especially because it was the first time that
Embraer was working with by-wire commands, acting
only on the rudder and on the elevator by electric
systems. The ailerons maintained hydraulic operation.
In the E2, which received the fourth generation of an
Embraer’s by-wire project, the engineers advanced
beginning to include ailerons’ electric commands.
The main advantage is weight reduction and better
flight envelope safety. The avionics was given a series
of improvements, in the future being able to have
enhanced flight vision system.E-ENABLED
The generation started to have the e-Enabled concept,
which, by means information and communication
integrated systems, improves the operating efficiency,
speeding up aircraft maintenance.WINGS
