2006 Boeing 777-200LR

Posted on by

Boeing declares that the 777-200LR aircraft will be the longest ranging airliner, being able of flying 16,417km (8865nm) - 18 hours flying time.
The 777-200LR is considered the world’s longest-range commercial jetliner and also it is capable of connecting virtually any two city pairs around the earth.
First, the 777-100X was a proposed shortened ultra long range (16,000km/8635nm) model, dropped in favor of the 777-200LR (originally 777-200X) design study.
In February 2006, Boeing delivered the first 777-200LR Worldliner (Longer Range), which carries 301 passengers up to 9,450 nautical miles (17,500 km).

It will achieve this with extremely powerful 489kN (110,000lb) thrust GE90-110B1 turbofans, a remarkably increased max takeoff weight and optional auxiliary fuel tanks in the rear cargo hold.
Other changes : 

  • 2m (6.5ft) raked wingtips;
  • structural strengthening;
  • new main landing gear;
  • optional overhead crew;
  • flight attendant rest stations above the cabin;

The 777-200LR was launched in 2000, but is now delayed until 2006.
Provisions for up to three optional fuel tanks have been added in the aft cargo area of the 777-200LR to be able to fly a range of 9,395 nautical miles (17,395 km) with full passenger payload (301 passengers).
The 777-200LR adds value to the 777 family, and particularly complements the popular 777-200ER. On long-range routes served by the 777-200ER, the 777-200LR provides an additional 47,250 pounds (21,430 kg) of revenue cargo capability.

The 777-200LR also serves as the platform for the Boeing 777 Freighter, the world’s largest, most capable twin-engine freighter.
The first 777 Freighter entered service in February 2009.
The Boeing 777-200LR Worldliner and 777-300ER (Extended Range) are two new long-range aircrafts that Boeing developed to offer airlines extra flexibility in serving the nonstop routes that passengers require. The 777-300ER entered service in May 2004 and the 777-200LR followed in March 2006.

Largest Long-range Twin-engine Jetliner

The 777-300ER extends the 777 family’s span of capabilities, bringing twin-engine efficiency and reliability to the long-range market. The aircraft transports 365 passengers up to 7,930 nautical miles (14,685 km).
Boeing incorporated several performance developments for the 777-300ER, extending its range and payload capabilities.

Excellent performance during flight testing, combined with engine efficiency developments and design transformations that reduce drag and aircraft weight, contributed to the increased capability. The benefits were also applied during development of the 777-200LR and the 777 Freighter.

Longest Range Commercial Airplane in the World

One of the newest members of the 777 family, the 777-200LR Worldliner has the capability to connect virtually any two cities in the world nonstop.

The 777’s advanced wing enhances the airplane’s ability to climb quickly and cruise at higher altitudes and speeds than competing aircrafts.
It also permits the airplane to carry full passenger payloads out of many high-elevation, high-temperature airfields.

Raked 6.5-foot wingtips have been improved to the 777-200LR and 777-300ER to increase the overall aerodynamic efficiency of the wing. The raked wingtip helps reduce takeoff field length, increase climb performance and reduce fuel burn.

The improved wing design for this aircraft, with a span of 199 feet 11 inches (60.9 meters), increases its ability to achieve higher cruise speeds, climb quickly and cruise at higher altitudes than competing aircrafts.
It also permits the aircraft to carry full passenger payloads out of many high-elevation, high-temperature airfields.

Raked 6.5-foot wingtips have been added to the 777-200LR and 777-300ER to improve the overall aerodynamic capability of the wing. The raked wingtips help reduce takeoff field length, amplify climb performance and reduce fuel burn.

Technology

Approximately 35 percent of the 777-300ER and 777-200LR Worldliner design has been changed from earlier 777 models, although passengers won’t notice it.

Each wing is being extended by 6.5 feet by adding raked wingtips to improve overall aerodynamic efficiency. The raked wingtips help reduce takeoff field length, increase climb performance and reduce fuel burn.
The body, wing, empennage and nose gear of the airplanes were strengthened and new main landing gear, wheels, tires and brakes were installed.

Maximum Takeoff Weight 766,000 lbs (347,450 kg)

The struts and nacelles were modified to accommodate the significantly higher-thrust engines.Tail-strike protection is standard on both models. This software feature helps prevent inadvertent scraping of the tail on the runway at takeoff or landing by commanding elevator movement if the airplane’s attitude exceeds pre-set limits.
The airplanes are powered exclusively by the General Electric GE90-115BL engine, the world’s largest and most powerful commercial jet engine, producing 115,300 pounds of thrust (derated to 110,100 lbs. on the 777-200LR).
Longest Range Commercial Airplane in the World
One of the newest members of the 777 family, the 777-200LR Worldliner has the capability to connect virtually any two cities in the world nonstop. It will carry more passengers and more revenue cargo farther than any other jetliner. Also, the 777-200LR can carry a full cargo load on routes where other airplanes are payload limited.
This gives airlines the capability to carry the same number of passengers farther, and with additional revenue-generating cargo.

The 777-200LR also serves as the platform for the Boeing 777 Freighter, the world’s largest, most capable twin-engine freighter. The first 777 Freighter entered service in February 2009.
Like other members of the 777 family, both the 777-200LR Worldliner and the 777-300ER will give you the widest seats in all classes when compared to the A340.
First-class passengers on all 777 models have 21-inch (53 cm) wide seats, which allow passengers to enjoy the same level of comfort as on the 747.
Business-class seats are 20 inches (50 cm) wide — the same width as the A340’s first-class seats.
Economy class has standard 18.5-inch (47 cm) wide — the widest in the industry — compared to 17.2-inch (44 cm) wide seats on the A340.

Overhead Space Options

The Boeing 777-200LR Worldliner offers overhead crew and attendant rest areas in the fuselage crown above the passenger cabin. Most aircrafts have crew rest areas either in the passenger cabin or in the cargo section. By moving crew and attendant quarters off the main deck, 777 operators can free as many as four-to-seven revenue passenger seats.
By utilizing the overhead space, the 777-200ER (Extended Range) and 777-200LR (Longer-Range) can save up to four passenger seats and four cargo containers, and the 777-300ER saves up to seven seats and six cargo containers. This frees up the seat and cargo space and results in additional revenue potential.

Boeing 777-200LR Avionics

In response to airline inclination, the layout of the 777 flight deck is in a horizontal format similar to that of the 747-400.
On six large display screens are presented: principal flight, engine information and navigation.

Although these displays resemble conventional cathode ray tube (CRT) screens, they contain superior liquid-crystal display technology.
The depth of the new flat panel displays is about half that of CRTs. In addition to saving space, the new displays weigh less and necessitate less power. They also generate less heat, which contributes to greater reliability and a longer service life. As another advantage, the displays do not require the heavy, complex air conditioning apparatus needed to cool equipment on previous flight decks. Pilots are grateful because that flat panel displays remain clearly visible in all conditions, even direct sunlight.

Boeing 777-200LR Engine

The three engine manufacturers developed more capable and quieter turbofans to power the 777. All three engines offer exceptional fuel efficiency.

Key factors in this achievement are new, larger-diameter fans with wide-chord fan blade designs and bypass ratios varying from 6-to-1 to as high as 9-to-1. This compares to the typical 5-to-1 ratio for the engines of previous twin-aisle jets.

In May 2005, Boeing launched the 777 Freighter.
Based on the 777-200LR platform, the 777 Freighter will fly 4,880 nautical miles (9,038 km) with a full payload and general cargo market densities — making it the world’s most capable twin-engine freighter.

Pricing and Cost


In 2008 the price for the Boeing 777-200LR was between $ 237.5 - 263.5 million.
The Boeing 777-200LR Worldliner and 777-300ER have seat-mile costs that are 18 to 20 percent lower than the A340-500 and A340-600 models.
For example, on a typical ultra-long-range route, such as Dubai to Los Angeles, the 777-200LR can carry 21 more passengers and 20,400 lbs. (9,250 kg) of additional cargo, compared to the A340-500. The twin-engine 777-200LR also consumes nearly 6,000 gallons (22,760 liters) of less fuel per flight.
