The Boeing 787-9 Dreamliner is a super-efficient aircraft, bigger than the 787-8.
Both airplanes are very competent having new passenger-pleasing traits.
Using 20 percent less fuel than any other aircrafts of their size, these models will give you the economics of large jet transports to the middle of the market.
When the 787-9 aircraft was launched, it had the same fuel capacity as the other two models: Boeing 787-8 and Boeing 787-3.
The stretched 787-9, which was designed with payload capability and greater range will be the first variant of the 787 with a "stretched" (lengthened) fuselage, seating 250–290 in three classes, having a range of 8,000 to 8,500 nautical miles (14,800 to 15,750 km).
The design modifications suggested higher weight and come out having a slightly shorter range than the 787-8.
Changes for the better
This variant is a little bit different in some ways than Boeing 787-8, including structural strengthening, a lengthened fuselage, a higher fuel capacity, a higher maximum take-off weight (MTOW), but this airplane has the same wingspan as the Boeing 787-8 .
The entry into service date, initially planned for 2010, was scheduled for early 2013, Boeing is targeting the 787-9 to compete with both passenger variants of the Airbus A330 and to replace their own 767-400ER. Like the 787-8, it will also open up new non-stop routes, flying more cargo and fewer passengers more competently than the 777-200ER or A340-300/500.
Some good changes are coming also : one known area is an increase in the APU power output from 225 KVA on the -8 to 250 KVA on the -9, along with a revised cargo environmental control system.

The design changes were incorporated to add a forward tank to improve its fuel capacity.
Now this aircraft will have a longer range and a better MTOW than the other two models.
Composite fibers—carbon graphite, held together by epoxy—account for 50 percent of the overall fuselage, versus the 9 percent in the 777, making the 787 lighter and stronger than aluminum-body aircraft.
The 787-9 fuselage is designed to be assembled in one-piece composite barrel sections.
Each barrel would be produced in one piece and than joined together end to end during final compilation.
The composite barrel approach was a taking away from the multiple aluminum sheets and fasteners used on existing and eliminated the need for some 50,000 fasteners used in conventional aircraft production.
The lowest seat-mile cost
The Boeing 787-9 will fly non-stop from Manila to New York or from Moscow to São Paulo, having the lowest seat-mile cost of the three 787 variants.
The launch customer for this aircraft is Air New Zealand, but also Qantas, Etihad Airways and Singapore Airlines have placed orders for 787-9 aircraft.
According to ILFC’s Steven Udvar-Hazy, the 787-9’s operating empty weight is around 14,000 lb (6,350 kg) overweight, which also could be an important obstacle for the future 787-10.
Boeing 787-9 Dreamliner Interior
It has a ‘stretched fuselage’ and will seat 250-290 passengers with a range of 8,000 to 8,500 nm (14,800 to 15,750 km).
The newest 787 family will to carry passengers on routes between 3,500 and 8,500 nautical miles (6,500 km to 15,750 km). It has been developed to be super-efficient in fuel consumption with reduced environmental impact while offering high comfort for the passengers.
Boeing 787-9 Dreamliner Engines
The Boeing 787 family can be powered alternatively by both the General Electric’s GENX (General Electric Next Generation) and Rolls Royce’s Trent 1000 depending on customers requirements. Two engines will enable the Dreamliner to fly at a cruise speed of Mach 0.85, while using less fuel (approximately -20%) than current airliners of the same class.
787-9 Dreamliner combines lightweight materials with advanced communications systems and thrifty engines—the company claims the 787 will burn 20 percent less fuel than the comparably sized 767.
Each version can be configured in single (baseline and stretch version), two (short version) or three (baseline and stretch version) classes. Each configuration can accommodate a different number of seat/passengers.

The new engines are more efficient being developed by GE and RR.
But the Dreamliner has other important parts like: the majority of the fuselage and wing that will made an unprecedented open architecture for rapid configuration. The benefits do not stop here, there are also highly appreciated: the new design techniques.
Boeing estimates up to 3,500 787 jetliners being ordered during the life of the program which would be between 20 and 40 years.
In the next few years before entry into service of the first Dreamliner scheduled for 2008, the Boeing Company could receive orders totaling 200 to 500 airplanes.
Boeing 787-9 Dreamliner Avionics
The 787 cockpit has dual head-up displays and electronic flight bags (EFB), which hold digital versions of the pilot’s maps, charts and manuals. The EFBs also offer ground navigation systems that help flight crews negotiate unfamiliar airports.
Reducing pilot error during taxiing will help cut the risk of runway collisions.
