Boeing 777-200LR
The Boeing 777-200LR is the newest passenger member of the 777 family and has the capability to connect virtually any two cities in the world without having the need to land and refuel. In fact, the 777-200LR (Longer Range), also known as Worldliner, became the world's longest range airliner after it entered service in 2006. It is capable of flying well over 9.000 nautical miles within an 18 hour timespan. The aircraft was developed alongside the larger Boeing 777-300ER and is powered by General Electric GE90-110B1 turbofans. Compared to the baseline 777-200, the -200LR features an increased MTOW together with three optional auxiliary fuel tanks located in the rear cargo hold. Other features include raked wingtips, a strengthened main landing gear and additional structural strengthening.

777 Versions

The first 777-200LR rolled-out of the Boeing factory on February 15, 2005 and first flew roughly a month later on March 8, 2005. Eventually, the 777-200LR was put into service in February 2006 by Pakistan International Airlines (PIA). Initially, the 777-200LR was proposed as the 777-100X and would have been a shortened version of the baseline 777-200. The shorter fuselage length would allow more of the take-off weight to be fuel dedicated, thus increasing range. A disadvantage of this design would mean that the aircraft could carry fewer passengers compared to the 777-200 while having similar operating costs. Consequently, costs per seat would have been higher. With the development of more powerful engines, the 777-100X design was replaced by the 777X program that later evolved in the 777-200LR.

Furthermore, in July 2008 the first Boeing 777-200 freighter airplane became airborne. This airplane is a derivative of the 777-200LR and differs from the original model in that it carries freight only.

Boeing 777-200LR Design

The Boeing 777-200LR is specically designed to fly ultra long-range distances. Provisions for up to three optional fuel tanks have been added in the aft cargo aera of the aircraft to be able to fly a range of 9,380 nautical miles (17,370 kilometers) with full passenger payload (301 passengers). Remarkable is the fact that even without the optional fuel tanks, the Boeing 777-200LR is able to fly as far as its closest competition, the A340-500. Due to its exceptional design characteristics the -200LR complements the popular 777-200ER.

Approximately 35 percent of the 777-200LR Worldliner and 777-300ER design has been changed from earlier 777 models, which is primarily found in the overall structure of the aircraft. The body, wing, empennage and nose gear of the aircraft were strengthened and new main landing gear, wheels, tires and brakes were installed.

 
Structure

The progress that has been made in the development and fabrication of advanced composite materials is evident in the Boeing 777. Composites of carbon and toughened resin is used in the skins fo the tailplane, fin torsion boxes and cabin floor beams. Other composite applications include those on secondary structures such as aerodynamic fairings. In fact, composites, including resins and adhesives, account for 9 per cent of the 777's structural weight, compared to some 3 per cent on other Boeing aircraft.

The wings on the Boeing 777 are seen as one of the most aerodynamically efficient airfoils ever developed for a subsonic commercial airliner. The more advanced wing, which is a further refinement of desigs introduced on the Boeing 757 and 767, enhances the airplane's ability to achieve higer cruise speeds, climb faster and cruise at higher altitudes than competing airliners. In addition, each wing of the 777-200LR has been extended by 6.5 feet by adding raked wingtips to improve overall aerodynamic and fuel efficiency. Furthermore, the entire fuel volume is accomodated within the wings and its structural center section. Overal fuel capacity ranges from 31,000 gallons (117,335 litres) for the 777-200 to 53,440 gallons (202,287 litres) for the 777-200LR.

 
Landing Gear
Similar to the 777-300ER, the -200LR is fitted with a new sem-levered landing gear. The unique gear allows the airplane to rotate early by shifting the center of rotation from the main axle to the aft axle of the three-axle landing gear truck. As the airplane rotates, the nose is allowed to rise higher earlier. Although this feature is independent of the Tail-Strike Protection system, it gives customers the ability to take-off on shorter runways or put more payload on the airplane for the same length of runway.
 
Flight Deck
The layout of the 777 flight deck is in a horizontal format similar to that of the 747-400. Principal flight, navigation and engine information is presented on six large display screens which incorporate advanced liquid-crystal display technology. Besides the Primary Flight Display and Navigation Display, the flight deck of the 777 is fitted with three multipurpose control display units (CDUs), installed in the center aisle stand, providing data display and entry capabilities for flight management functions. In fact, these CDUs are the primary interface with an integrated Airplane Information Management System (AIMS). AIMS provides flight and maintenance crews all pertinent information concerning the overall condition of the airplane, its maintenance requirements and its key operating functions, including flight, thurst and communications management.
 

Flight Controls

The 777 is Boeing's first airliner fitted with a fly-by-wire system, which is fully powered by control surface actuators electrically signalled from the full FBW system. Unlike Airbus, Boeing decided to retain conventional control yokes rather than a side-stick. Boeing's vision was that control yokes were more intuitive for pilots. In addition, the normal control columns and rudder pedals are back-driven by the system to give the pilots direct appreciation of the activity of the automatic system.
 
Interior
The cabin of the 777 is fitted with the so-called Boeing Signature Interior which has since been used on other aircraft like the Boeing 767-400ER, 747-400ER, 737NG (partly) and 757 (partly). Furthermore, the 777 features larger windows than those on many other aircraft thus enhancing passenger experience. The style of these windows, i.e. more rounded, was later adopted on aircraft like the 767-400ER and 747-8. The spacious cabin also provides crew rest areas located in the crown area above the cabin. Separate crew rests can be included for both flight and cabin crew, with a two-person crew rest above the forward cabin between the first and second doors, and a larger overhead crew rest further aft with multiple bunks.
 
Engines
The Boeing 777-200LR is powered by two GE90-110B1 turbofans, one of the most powerful engines ever build. The engine is rated at 110,000 lbf and provides the aircraft with exceptional performance characteristics.
 
Engines
On November 10, 2005 the Boeing 777-200LR established a new world record for distance traveled nonstop by a commercial airplane. The aircraft flew a total distance of 11,664 nautical miles (21,601 km) during a 22-hour 42-minute flight between Hong Kong and London flying eastbound. The distance set is by far the longest than any previous commercial jetliner has flown. As said, additional fuel capacity in the rear cargo hold enables the 777-200LR to fly this far. Compared to the baseline 777-200, the -200LR features raked wingtips which even further increases fuel efficiency.

Boeing 777-200 Information
The Boeing 777-200 is the base-line model of the 777. The first aircraft was delivered to United Airlines in May 1995. The aircraft was build by Boeing's non-destructive testing campaign in 94' - 95', and provided valuable knowledge for the later 777 programs.
 
Boeing 777-200ER
Boeing 777-200ER Information
The Boeing 777-200ER was taken into service in 1997, roughly two years after the first 777 was delivered to United Airlines. It featured increased fuel capacity as well as more powerful engines. ER stands for Extended Range as the -200ER is able to fly significantly farther than the -200. The first airframe was delivered to British Airways.
