All of the answers here are great. I’d like to add one thing. When Boeing (or any aircraft manufacturer) creates a new aircraft, they have to test it very rigorously before the FAA says they will certify it, in order to begin selling it for produc. Boeing is set to debut its biggest plane ever next month, and the 777X has finally been paired with the gargantuan GE9X engine that will propel its flight. The plane is currently housed in Boeing's. ANA Boeing 777 suffers engine vibrations, declares emergency An All Nippon Airways (ANA) Boeing 777 was forced to divert to Chicago O'Hare Airport, the US, after suffering engine vibrations during the flight to Tokyo-Narita International Airport, Japan. The Federal Aviation Administration (FAA) issued an emergency airworthiness directive (AD), warning Boeing 777-300ER powered by GE engines of a potentially unsafe condition affecting the power plants. This is the second emergency AD, which follows an uncontained engine fire incident back in October 2019. Our Boeing 777-200ER aircraft offers a variety of signature products and experiences unlike anything else in the sky. Visit delta.com to learn more.

The Boeing 777 is a large twin engine jet transport designed for regional and extended range service. The primary electrical system is a 3-phase, 4-wire, constant frequency 400 Hz, 115/200 Volt system, which has been the industry standard on commercial jet transports since the Boeing 707 (and maybe before, but that's as far back as I go). The neutral is connected to the airframe so that single phase circuits are supplied with a single wire, using the airframe as the return circuit. There is also a 28 Volt direct current system with the negative pole connected to airframe, such that 28 VDC services are also supplied with a single wire using the airframe as the return circuit. The 28 VDC power is derived from the AC power system by transformer-rectifiers.

The primary in-flight electrical source on the 777 is a 120 kVA constant speed two-pole brushless alternator. This represents a 33% increase in capacity over the next largest electrical source on previous Boeing commercial jet transports, the 747-400, 757 and 767. The alternator in these machines is integrated with an axial gear differential/hydraulic constant speed drive. The speed on the 120 kVA machine maintains an average 24,000 rpm plus or minus about 1%. This is currently the lightest weight technology in kVA per pound for supplying a 400 Hz constant frequency system, actually weighing just slightly less than the 40 kVA drive/alternator on the earlier Model 727. Minimizing weight has been achieved partly by increasing the alternator speed, partly by improved packaging and partly by switching from air cooling to oil cooling. The progression on Boeing airplanes has been from air-cooled 6000 rpm machines on the 707, 727, 737-100/200/300/400's and 8000 rpm machines on the 747-100/200, to oil-cooled 12,000 rpm machines on the 767, 757 and 740-400, and ultimately to 24,000 rpm machines on the 777. The 24,000 rpm constant speed Integrated Drive Generator, or IDG as it is referred to, was a mature technology also in service on the McDonnell Douglas MD-11 and Airbus A330.

The system on the Boeing 777 is configured with one IDG per engine, driven directly from the engine gearbox. There are two main electrical distribution buses, a left main bus and a right main bus, each normally supplied independently by their respective IDG. There is a third main alternator driven from an auxiliary gas turbine engine (called the auxiliary power unit or APU for short) located in the tail of the airplane, which is also rated at 120 kVA. Since the APU runs at a constant speed, this 24,000 rpm alternator is a direct drive, i.e., not an IDG. It is, however, essentially the same alternator used in the IDG. While the APU alternator is primarily a ground power source for the airplane, it can also be operated in flight to replace the loss of one engine driven IDG.

The 777 also incorporates a second power generation system, called the Backup System. This is a 25 kVA system intended to support essential services in the unlikely event of loss of all main alternators. Nfl bets to make. A variable speed direct drive alternator was selected for this system to minimize the size of the engine installation. There is one backup alternator per engine directly driven from the engine gearbox at approximately 14,000 to 28,000 rpm. The output power of this alternator, at a frequency of 933 Hz to 1867 Hz, is converted to a constant 400 Hz by an electronic converter in the fuselage. Also incorporated within this machine are two permanent magnet alternators which are used as isolated independent supplies for the electronic flight controls system.

Flight instruments on the 777 are primarily powered by 28 Volts DC. Direct current power is supplied by three-phase transformer-rectifier units. There are four such units each rated at 120 Amperes. The choice of using 28 VDC instruments facilitates powering these instruments from battery power when necessary. Flight instruments and flight controls can also be powered from a Ram Air Turbine driven alternator which deploys automatically for loss of all engine driven generator power.

Each engine on the 777 has a diameter approximately the size of a 737’s fuselage

All of the engines on the Titanic delivered around 46,000 horsepower combined. Just one of the GE units on the 777 puts out over 111,000 horsepower

During certification testing in 2002, the GE90-115B engine (777-300) set a world-record 127,900 lbs. of thrust. The GE90-115B ran for approximately 60 hours at triple red-line conditions (max fan speed, core speed and exhaust gas temperature) to evaluate the engine at its operational limits and demonstrate its capability beyond the most extreme operating conditions

There are 3 million parts in a Boeing 777 provided by more than 900 suppliers

The 777 was named winner of the prestigious Robert J. Collier Trophy by the U.S. National Aeronautic Association, which honored the Boeing 777 as the top aeronautical achievement of 1995

The 777 can cruise at altitudes up to 43,100 feet

Boeing engineers designed and electronically pre-assembled the 777 using computers. New laboratory facilities enabled the various airplane systems to be tested together as a single integrated entity in simulated flight conditions, before the first jetliner took to the air

The 777’s landing gear is the largest ever in a commercial jetliner. With six wheels on each main landing gear, and two wheels on the nose gear, it has an unmistakable footprint

The Fédération Aéronautique Internationale recognized the Boeing 777 in April 1997 for achieving a speed and distance record for airplanes in its size and class. The 777 set the “Great Circle Distance Without Landing” record, traveling 10,823 nautical miles (20,044 kilometers or 12,455 miles), and it set the record for “Speed Around the World, Eastbound,” traveling at an average speed of 553 mph (889 kilometers per hour)

On May 30, 1995, the 777 became the first airplane in aviation history to earn U.S. Federal Aviation Administration (FAA) approval to fly extended-range twin-engine operations (ETOPS) at entry into service. On that date, the FAA awarded the Pratt & Whitney-powered Boeing 777, 180-minute ETOPS

The 777 underwent the most extensive flight-test program ever conducted on a commercial jetliner. The flight-test program included nine airplanes, which flew more than 7,000 hours and 4,900 flights

The data shared and transferred on the network during the design phase of the 777 program totaled 1,847,930,000,000 bytes of production data. If you collected the equivalent of all this data on 3.5-inch diskettes the stack of these diskettes would be 13,368 feet (4,074.5 meters), which is taller than Mt. Fuji in Japan, which stands 12,338 feet (3760.6 meters)

Today’s Boeing 777 operators enjoy a 99 percent dispatch reliability rate

The flight control system for the 777 airplane is different from those on other Boeing airplane designs. Rather than have the airplane rely on cables to move the ailerons, elevator, and rudder, Boeing designed the 777 with fly-by-wire technology. As a result, the 777 uses wires to carry electrical signals from the pilot control wheel, column, and pedals to a primary flight computer
