Boeing and Airbus have planned to renew some of their aircrafts instead of building complete new planes. These renewed airplanes we are going to talk about in this post are for Boeing and Airbus. For Boeing: 777X, 737 MAX and 747-8 and for Airbus: a320 NEO family and a330 NEO .
Building on the success of the 777 and 787 Dreamliner, the 777X will be the largest and most efficient twin-engine jet. Unmatched in every aspect of performance. The cabin interior of the 777X, inspired by the comforts and conveniences of the 787 Dreamliner and includes larger windows, a wider cabin, new lighting and enhanced architecture, all of this will be customizable by airlines.
The Boeing 777X is a new series of the long-range wide-body twin-engine Boeing 777 family that is under development. The 777X is to feature GE9X new engines, new composite wings with folding wingtips and technologies from the Boeing 787. The 777X series launched in November 2013 besides with two variants: the 777-8 and the 777-9. The 777-8 has seating for 365 and range of over 16,110 km and the 777-9 has seating for 414 and range of over 14,075 km. The -9 is to fly in the first quarter of 2019 with deliveries beginning in December 2019.
The 737 MAX
The Boeing 737 MAX is an American narrow-body aircraft series. It is designed and produced by Boeing as the fourth generation of the Boeing 737, succeeding the Boeing 737 NG. The program launched on August 30, 2011. The first flight was on January 29, 2016. It gained FAA certification on March 9, 2017. The first delivery was a MAX 8 on May 6, 2017 to Malindo Air, which debuted it on May 22, 2017.
The 737 MAX has 5 variants. The 737 MAX7, the 737 MAX8, the 737 MAX200, the 737 MAX9 and the 737 MAX10. Every variant is bigger than the previous one, carrying more passengers.
In summer of 2011, the objective was to match the A320neo 15% fuel burn advantage. However, the initial reduction was 10-12%. It enhanced later to 14.5%. The turbofan widened from 61 inches to 69.4 by raising the nose gear and placing the engine higher and forward. The split winglet added 1-1.5%, a relofted tail cone 1% more and controlling electronically the bleed air system improves efficiency.
The Boeing 747-8 is a wide-body jet airliner by Boeing. Officially announced in 2005, the 747-8 is the third generation of the 747. It has a lengthened fuselage, redesigned wings, and improved efficiency. Furthermore the 747-8 is the largest 747 version, the largest commercial aircraft built in the United States, and the longest passenger aircraft in the world.
The 747-8 offers two main variants: the 747-8 Intercontinental (747-8I) for passengers and the 747-8 Freighter (747-8F) for cargo. The first 747-8F performed the model’s maiden flight on February 8, 2010, with the 747-8I following on March 20, 2011. Delivery of the first freighter aircraft occurred in October 2011 and the passenger model began deliveries in 2012. As of September 2017, confirmed orders for the 747-8 total 135, 88 of the freighter version, and 47 of the passenger version.
The 747-8 was designed as the first lengthened 747 to go into production. Both the 747-8 and shortened 747SP are the only 747 variants with a fuselage of modified length. Besides, the 747-8 was intended to use the same engine and cockpit technology as that of the 787, including the General Electric GEnx turbofan. Boeing said that the new design would be quieter, more economical, and more environmentally friendly than previous versions of the 747. As a derivative of the already-common 747-400, the 747-8 has the economic benefit of similar training and interchangeable parts. Boeing firmed the 747-8 Freighter’s configuration in October 2006.
The a32o NEO Family
The A320neo was stated for service entry in spring 2016, the A321neo six months later and the A319neo again six months after, all of them are the so called a320 Family. The A320neo and A321neo flew around 4,000h for both powerplant versions certification. This is about three-quarters of the certification effort of a new design. This airplane is the most successful single-aisle airplane of all manufacturers. Consequently, almost every short-range airline orders this type of aircraft for its fleet.
In 2006 Airbus started the A320 Enhanced (A320E) programme as a series of improvements targeting a 4–5% efficiency gain with large winglets (2%), aerodynamic refinements (1%), weight savings and a new aircraft cabin. At the time Airbus’ Chief Operating Officer and executive member John Leahy said “Who’s going to roll over a fleet to a new generation aircraft for 5% better than an A320 today?
Engine improvements reducing fuel consumption by 1% were fitted into the A320 in 2007 with the CFM56 Tech Insertion and in 2008 with the V2500Select parts. Lufthansa took delivery of the first A320neo on 20 January 2016. Two hundred deliveries are targeted in 2017. The fourth and latest final assembly line in Hamburg should open in July 2017.
The a330 NEO
The new a330 NEO made its inaugural flight a couple weeks ago. Departing from Toulouse-Blagnac Airport in southwestern France, the first a330 NEO put through its paces during a four hour and 13 minute evaluation. An audience of invited airline executives, industry suppliers, air transport officials, national authorities, the news media and Airbus employees, witnessed the takeoff and the landing of the aircraft
The maiden flight was an A330-900. When entering airline service by mid-2018, this aircraft will become the lowest seat-mile-cost jetliner in the widebody category, continuing the success of Airbus’ A330-300 variant (the best-selling midsize widebody ever).
The smaller a330-800, with 250 seats, will join its brother. Rolls-Royce’s latest Trent 7000 Turbofan Powerplants power both a330-800 and a330-900. Both incorporate high-span wings featuring 3D-optimised aerodynamics, new onboard systems, a connected cockpit, and the “Airspace by Airbus” cabin interior.
By offering the A330 NEO along with A350 XWB, Airbus has created a world-leading widebody empire.
