In-Flight Uncontained Engine Failure Airbus A380-842, VH-OQA
In-flight uncontained engine failure Airbus A380-842, VH-OQA overhead Batam Island, Indonesia on 4 November 2010 What happened and why Shortly after taking off from Changi Airport, Singapore, the No. 2 engine on a Qantas Airbus A380 failed about 7,000 ft above Batam Island, Indonesia. The failure sent engine fragments through the left wing and damaged some of the aircraft’s systems. The engine failure was a result of an oil feed stub pipe that was incorrectly manufactured with a thin wall that resulted in fatigue cracking of the pipe. This crack released oil into the engine during the flight, which caused an internal fire. That fire led to one of the engine’s turbine discs fracturing and then rapidly over speeding before it burst, broke free of the engine casing, and impacted the A380’s airframe. What happened to the aircraft? The damage to the aircraft from the disc fragments resulted in the aircraft’s hydraulic, electrical and other systems being degraded. Despite the damage, the flight crew managed the multitude of system failures before safely returning the aircraft and landing at Changi Airport without any injuries to the crew and passengers. What’s been done to prevent this from happening again? The ATSB, Rolls-Royce, aviation regulators, and operators of Trent 900-powered A380s took a range of steps to ensure that engines with incorrectly manufactured oil feed stub pipes were removed from service or managed to enable the aircraft to continue to operate safely. Rolls-Royce also introduced software that would automatically shut down a Trent 900 engine before its turbine disc over speeds, in the unlikely event of a similar occurrence. -

The Boeing 787 Case
Managing New Product Development and Supply Chain Risks: The Boeing 787 Case Christopher S. Tang and Joshua D. Zimmerman1 To stimulate revenue growth and market response, Boeing decided to develop the UCLA Anderson School 787 Dreamliner.

However, despite significant management efforts and capital Commented by investment, Boeing is currently facing a series of delays in its schedule for the maiden James I.

This paper analyzes Boeing's rationale for the MBCP, CORP 787's unconventional supply chain, describes Boeing's challenges for managing this Business Continuity Services supply chain, and highlights some key lessons for other manufacturers to consider when designing their supply chains for new product development.

Development of Trent Series Large Turbo Fan Engines
Technical Description Development of Trent Series Large Turbo Fan Engines As the demand for aircraft has been increasing, fuel efficiency needs to be improved. Therefore, the performance of the engine as well as the fuselage must be enhanced. We are in charge of design, part manufacturing and module assembly of the intermediate pressure compressor (IPC) at development of all the Trent Series large turbo fan engines from Rolls-Royce after the Trent 1000, the first model of which helped develop in 2004, as their strategic partner. Going forward, we will promote activities to take charge of the overall IPC module as an IPC module integrator by developing ©Rolls-Royce plc proprietary design and manufacturing technologies. Introduction Aircraft are an essential means of transportation in To be launched in 2018 global society, and aircraft manufacturers are competing Trent 7000 Thrust: to develop new types of aircraft. Engines equipping such 68,000-72,000lb Airbus A330neo aircraft must be highly reliable, lightweight and fuel efficient, as well as environmentally friendly (low NOx, low Trent XWB noise). Thrust: 84,000-97,000lb Airbus A350 XWB 1 Background Trent 1000 The demand for aircraft is expected to grow by about Thrust: 53,000-74,000lb 5% annually even in the long term, pushed by factors Boeing 787 such as the rapid expansion of Low-Cost Carriers (LCCs). To meet such market needs, The Boeing Company in the Trent 900 US and Airbus in Europe are developing new types of Thrust: 80,000lb aircraft. Rolls-Royce plc (Rolls-Royce) in the UK, one of the Airbus A380 world's major aircraft engine manufacturers, has been developing and supplying its Trent series for such aircraft, Trent 500 Thrust: and we are participating in programs to manufacture the 60,000lb series as a Risk- and Revenue-Sharing Partner (RRSP). -
CO2 EMISSIONS from COMMERCIAL AVIATION: 2013, 2018, and 2019 Down from Nearly 19% in 2013
OCTOBER 2020 CO2 EMISSIONS FROM COMMERCIAL AVIATION 2013, 2018, AND 2019 BRANDON GRAVER, PH.D., DAN RUTHERFORD, PH.D., AND SOLA ZHENG ACKNOWLEDGMENTS The authors thank Jennifer Callahan and Dale Hall (ICCT), Tim Johnson (Aviation Environment Federation), and Andrew Murphy (Transport & Environment) for their review. This work was conducted with generous support from the Aspen Global Change Institute. SUPPLEMENTAL DATA Additional country-specific operations and CO2 emissions data for 2013, 2018, and 2019 can be found on the ICCT website. International Council on Clean Transportation 1500 K Street NW, Suite 650, Washington, DC 20005 [email protected] | www.theicct.org | @TheICCT © 2020 International Council on Clean Transportation EXECUTIVE SUMMARY Last year, the International Council on Clean Transportation (ICCT) developed a bottom-up, global aviation inventory to better understand carbon dioxide (CO2) emissions from commercial aviation in 2018. This report updates the operations and emissions analyses for calendar year 2018 based on improved source data, and includes new analyses for 2013 and 2019. In 2013, the International Civil Aviation Organization (ICAO) requested its technical experts develop a global CO2 emissions standard for aircraft, and states began to submit voluntary action plans to reduce CO2 emissions from aviation. This paper details a global, transparent, and geographically allocated CO2 inventory for three years of commercial aviation, using operations data from OAG Aviation Worldwide Limited, ICAO, individual airlines, and the Piano aircraft emissions modeling software. Our Global Aviation Carbon Assessment (GACA) model estimated CO2 emissions from global passenger and cargo operations on par with totals reported by industry (Figure ES-1). In all three analyzed years, passenger flights were responsible for approximately 85% of commercial aviation CO2 emissions. -
