United Airlines Takes Delivery of Fuel Efficient 737 MAX 9

CO2 emissions significantly reduced compared with older generation aircraft

Chicago, April 23, 2018: United Airlines announced today that it has taken delivery of its first 737 MAX 9 aircraft from the BoeingDelivery Center in Seattle, WA. The new aircraft, which arrived right after Earth Day, reduces fuel use and CO2 emissions significantly compared with older generation aircraft. In honor of this more eco-friendly aircraft, United has given the MAX a new livery, similar to its fuel-efficient Boeing Dreamliner aircraft, so that employees and customers can easily recognize the plane and its superior fuel efficiency.

United expects to take delivery of two more 737 MAX 9 aircraft this month, and will have ten 737 MAX 9 aircraft by the end of 2018. As previously announced, the aircraft will enter United’s schedule June 7 with service between the airline’s hub at Houston’s George Bush Intercontinental Airport and five cities – Anchorage, Alaska; Austin, Texas; Fort Lauderdale, FL; Orlando, FL. and San Diego. The aircraft will operate on additional routes from Houston and Los Angeles International Airport starting June 29.

United Airlines and United Express operate approximately 4,600 flights a day to 354 airports across five continents. In 2017, United and United Express operated more than 1.6 million flights carrying more than 148 million customers. For more information, please visit united.com.

Boeing’s 787-10 Dreamliner Cleared for Commercial Service by FAA

sustainable aviation

25 % better fuel per seat and emissions than current airplanes

Everett, Wash., Jan. 22, 2018: Boeing announced today the 787-10 Dreamliner received an amended type certificate (ATC) from the U.S. Federal Aviation Administration (FAA), clearing the airplane for commercial service.

The awarding of ATC caps a successful flight test program that began in March 2017 and involved three flight test airplanes that accumulated about 900 test hours. Boeing’s flight test program team took the airplanes through a series of tests to confirm the airplane’s handling, systems and overall performance met internal requirements and certification standards to ensure safety of flight.

Other aviation regulatory agencies are expected to follow the FAA’s lead and certify the airplane before it enters service.

The Boeing 787 Dreamliner is a family of super-efficient airplanes with new passenger-pleasing features. As a stretch of the 787-9, the 787-10 retains over 95 percent commonality while adding seats and cargo capacity, setting a new benchmark for fuel efficiency and operating economics at 25 percent better fuel per seat and emissions than the airplanes it will replace. The airplane can fly 330 passengers, in a typical two-class configuration, up to 6,430 nautical miles (11,910 km).

To date, Boeing has over 170 orders for the 787-10 from nine customers worldwide. First delivery is expected to Singapore Airlines in the first half of 2018.

Rolls-Royce Sets New Aerospace Record with UltraFan® Power Gearbox

sustainable aviation

25% fuel efficiency improvement over the first generation of Rolls-Royce Trent engines

Dahlewitz, Germany, September 4, 2017: Rolls-Royce today announced that it has set a new record for the world’s most powerful aerospace gearbox, just months after testing began. Speaking at the International Society for Air Breathing Engines (ISABE) conference in Manchester, UK, Paul Stein, Chief Technology Officer at Rolls-Royce, confirmed that the Power Gearbox had successfully reached 70,000 horsepower while on test at Rolls-Royce’s dedicated facility in Dahlewitz, Germany. The Power Gearbox will play a central role in the company’s next-generation UltraFan® engine, helping to deliver improved efficiency over a wide range of thrusts.

Testing of the first demonstrator gearbox began on a specifically designed rig in May and having proven that the Power Gearbox is capable of managing the equivalent power of around 400 family cars at full throttle, testing will now focus on lower power functions such as endurance and reliability.

Rolls-Royce’s Power Gearbox is designed to run all the way up to 100,000 horsepower and future demonstrators are expected to achieve these levels. When running at maximum power, each pair of teeth on the gearbox will transmit more power than an entire grid of Formula 1 cars between them.

The Power Gearbox has a planetary design, with each ‘planet’ capable of holding the force of a Trent XWB engine at full throttle. It is designed to allow the shafts at the core of the engine to run at very high speeds while allowing the fan at the front of the engine to run at a slower speed. The associated improvement in efficiency and reduction in weight will allow the UltraFan engine to offer a 25% fuel efficiencyimprovement over the first generation of Rolls-Royce Trent engines.

Commenting on the milestone, Paul Stein, Rolls-Royce – Chief Technology Officer, said: “Setting this record is a great achievement for the team and I’m proud we’ve managed to get there so quickly. Our Power Gearbox technology is central to the success of the next generation of Rolls-Royce jet engines and I’m pleased to see us pushing back engineering boundaries with this work.”

Arndt Schoenemann, Managing Director, Liebherr-Aerospace Lindenberg GmbH commented: “Reaching this milestone and impressive performance is proof of the great co-operation of all parties involved and especially of the expertise that accumulates in our joint venture with Rolls-Royce. Together, we are writing aerospace history.”

As well as high power testing, the Power Gearbox is also undergoing Attitude Rig testing, which simulates the effect of the gearbox being on the wing of an aircraft in flight, through phases such as take-off, climb, banking and descent.

Rolls-Royce is working in partnership with Liebherr-Aerospace, through our Aerospace Transmission Technologies joint venture, to develop manufacturing capability and capacity for the new Power Gearbox. Rolls-Royce leads the design definition and design integration of the project, as well as testing activities.

Reducing Green House Gas emissions in air transport: Rolls-Royce sets new aerospace record with all new UltraFan® Power Gearbox

The UltraFan engine, available from 2025, will feature:

  • Maximum fuel burn efficiency and low emissions through a new engine core architecture
  • Reduced weight through the use of Carbon Titanium (CTi) in fan blades and a composite casing
  • Increased efficiency through the use of ceramic matric composites (CMCs) which are heat resistant and require less cooling air
  • Efficient power for high by-pass ratio engines of the future through a geared design
