Dreamliner

Composite materials account for 50% (by weight) of the Dreamliner and aluminum alloys 20%. By way of contrast, the Boeing 777 consists of 11% composites and 70% aluminum alloys. These composite and aluminum contents as well as contents for other materials used in the construction of both 777 and 787 aircraft (i.e., titanium alloys, steel, and other) are listed in Table 16.11.

The fuselage of the Dreamliner was the first attempt to mass produce extremely large composite structures composed of carbon fibers embedded in a thermosetting polymer (i.e., an epoxy). Thus, it became necessary for Boeing (and its subcontractors) 

As Fignre 16.20 notes, carbon laminates are also used in wing and tail structnres. The other composites indicated in this same illustration are glass fiber-reinforced epoxy and hybrid composites, which are composed of both glass and carbon fibers. These other composites are nsed primarily in tail and trailing wing strnctnres.

The average cost of developing a new drug is estimated to be about US 1-1.2 billion, including expenditures on failed projects. This amount is about four times the price of an Airbus A380 at US 270 milhon, or hve times that of a Boeing B-787 Dreamliner at US 200 milhon. 

The Boeing 787 Dreamliner was the first aircraft in which the structure was made out of 50% composite materials (Morazain, 2011). One of the drivers for composites is to use an inexpensive base material and a layer over with a thin...

The issue was one of holistic execution and quality control. The Dreamliner launch had multiple public delays due to a shortage ol las-teners. Conflicting specifications, compliance issues, and coordination plagued the program, which translated into delay after delay. As a result, orders were canceled and renegotiated, and the schedule was pushed out. 

Composites have been used in aircraft construction for several decades but, until very recently, never in fuselage or wing construction. Conventional aircraft such as B747 or MD80 include less than 5% of carbon-reinforced composite. The new Boeing 787 commercial aircraft also called the Dreamliner (and Airbus A 350),... 

January 7,2013, Boston Logan Airport. Late in 2012, the Boeing Company introduced the 787 Dreamliner into commercial service. It was a new aircraft that implemented many new design features. One feamre was an onboard electrical support system using lithium-ion batteries. 

In 2007 Boeing launched their Boeing 787 Dreamliner in which pre-impregnated carbon fibre is used for polymer-matrix composite structural components [10]. 

The Boeing 737 Dreamliner utilises carbon fibre reinforced epoxy resin composite in its construction (Figure 7.1). 

Most airframe manufacturers are now adopting ARINC 653. For example, both Airbus A380 and Boeing 787 Dreamliner use ARINC 653. There is a strong trend towards adopting IMA throughout the aerospace industry.

The Airbus A380 and Boeing s Dreamliner have expanded the use of composites considerably, with content increasing from 23% on previous planes to over 50%. 

To help you better understand this core concept of Lean Safety, here is an example with which you can all identify. Just imagine yourself boarding one of Boeing s new Dreamliner airplanes. Shortly after taking off on this technological marvel of the 21st century, you will be confronted, or maybe rammed, with technology from 1955. 

In May 2006, the Boeing company announced its new game change aircraft, the 787 Dreamliner. Two of the innovative characteristics of the Dreamliner are the use of composite materials as the primary material in the construction of its airframe and the replacement of conventional hydraulic power sources with electrically powered compressors and pumps, thus completely eliminating pneumatics and hydraulics from several subsystems.
