What went wrong with the Boeing 787?
Boeing’s 787 Dreamliner has recently raised concerns after overheating batteries caught fire while the aircraft was parked at Boston’s Logan International Airport [67] . Initial investigations had suspected the two lithium-ion batteries, but where ruled out as voltages had not exceeded the battery limits. …
Did the 787 fail?
In 2013, the second year of service for the Boeing 787 Dreamliner, a widebody jet airliner, several aircraft suffered from electrical system problems stemming from its lithium-ion batteries. Boeing’s engineers, who failed to consider and test for worst-case battery failures.
Which engine is used in Boeing 787?
GEnx engine
The GEnx engine delivers proven performance for the Boeing 787 Dreamliner and Boeing 747-8. The GEnx is the fastest-selling, high-thrust jet engine in GE Aviation history with more than 2,700-plus engines in-service and on order.
Can 787 be grounded?
(Bloomberg) — Boeing Co. grounded eight of its 787 Dreamliner jets for inspection and repair after finding two manufacturing flaws that together could compromise the structural integrity of the aircraft.
Is Boeing 787 9 grounded?
In January 2013, the US FAA grounded all 787s until it approved the revised battery design in April 2013. The 787 flies with zero fatalities and no hull losses through July 2021. As of March 2020, the 787 had orders for 1,510 aircraft from 72 identified customers.
How high can a Boeing 787 fly?
Most commercial aircraft are approved to fly at a maximum of around 42,000 feet. This maximum is also known as a ‘service ceiling. ‘ For example, for the double-decker Airbus A380 ‘superjumbo’ quadjet, this ceiling is 43,000 feet. Meanwhile, for the Boeing 787-8 and -9 ‘Dreamliner,’ it is 43,100 feet.
Why was the propulsion system tested on the 787?
The 787 propulsion system was rigorously tested, both to achieve basic certification and to demonstrate full service readiness and extended operations (ETOPS) capability when the 787 entered service (see fig. 5). Intense engine development and 787 flight test programs contribute to the engines’ service readiness and durability.
How did the Boeing 787 engine system change?
Higher engine thermal efficiency through increased overall pressure ratio and improved component efficiencies. Improved thrust-to-weight ratio through the application of advanced materials. Introduction of a novel dual-use electrical power generation system that doubled as the engine start system.
How does the 787 onboard maintenance system work?
Through centralized fault reporting, the 787 onboard maintenance system (OMS) aids the airline mechanic in rapidly isolating faults and guiding the appropriate maintenance action (see fig. 7). The OMS is an essential tool in maintaining rapid airplane turnaround rates and maximizing dispatchability.
