Today, we thought we’d take a look at some of the distinct features of the Boeing 787
when it was introduced. Having had its first flight in 2009, the aircraft has been a big
hit with airlines (after some of its early issues were resolved… of course). In fact,
over 1,000 787s have been produced since the program began. Indeed, the jet’s popularity is
no surprise as there are many impressive features. So, let’s take a look at these in todays video.
First, Boeing made use of composites’ ability to adapt shape by creating the
787’s fuselage with several barrel pieces. Altogether, the robust presence of light
composites offers several efficiency and sustainability benefits. The Airbus A350’s
subsequent introduction also saw the widebody utilize composites in a similar fashion.
Composites, which are formed by two or more different materials with varying properties,
are stronger than the elements by themselves. They aren't new in aircraft manufacturing. However,
the 787 is 50% composite by weight and 80% by volume.
The breakdown of the aircraft’s composites is 20% aluminum,
15% titanium, 10% steel, and 5% other materials.
The composites at the wing are built with carbon fiber-reinforced polymer (CFRP), which has a
higher strength-to-weight ratio than standard aircraft metals, offering lightweight advantages
without compromises in strength. Offering fuel efficiency and, in turn, cost savings, this
approach makes the wings far more flexible, making the wings curve more prominently. Altogether,
the wings improve aerodynamic stability and allow the aircraft to experience less drag.
Boeing also proudly highlights that the leading edge of the vertical and
horizontal stabilizers on the 787-9 use hybrid laminar flow control,
which is a technique that evens out airflow and cuts down drag on the aircraft’s tail.
As the company puts it:
“Industry engineers worked to perfect hybrid laminar flow control technology for decades,
but the weight of the systems was more than the potential fuel savings. Finally,
Boeing engineers figured it out, and the 787-9 will be the
first production commercial jet to feature the innovative technology…”
Another feature is that the 787 entered service with an improved
fly-by-wire flight control system. Rather than aged mechanical processes,
the aircraft’s fly-by-wire systems convert flight deck crew inputs into electrical signals.
Boeing also replaced hydraulic brake power in preference of
electrical systems. The 787 also deploys a series of electrically
heated blankets to melt ice on the wing with its electro-thermal ice protection scheme.
The two large-format head-up displays were also
a distinct implementation that saw the flight deck get a revamp.
This helped both pilots gain more situational awareness while being fed crucial information.
On the passenger side, you might already be familiar with the Dreamliner’s dimmable
windows. Instead of going from bright sun to total blackout via a manual shutter,
those in the 787’s cabin can tailor their experience with a press of a button. They can
transition from light to darkness gradually, offering a more bespoke customer experience.
