BOEING

Boeing traces its history to aviation pioneer William Boeing

Founded in 1916

One of world's largest aerospace company and leading manufacturer of commercial jetliners 

Major service provider to NASA, Boeing is the prime contractor for the International Space Station

12,000 Boeing-built commercial jetliners are in service worldwide, which is roughly 75 percent of the world fleet

Aircrafts- 737, 747, 767, 777 and 787

President and CEO- Ray Conner

The Boeing 777

World’s largest twin engine airplane

Had to achieve significant reductions in structural weight while maintaining overall affordability.

Development of breakthrough materials.

Advanced 7000 and 2000 series aluminum alloys, damage-tolerant composites, and advanced titanium alloys

A reduction in weight of over 5800 pounds

Seventy percent of the overall structure is aluminum, including the wing box and fuselage

The vertical fin, horizontal stabilizers, and passenger-floor beams utilize a boeing/supplier developed toughened, damage-resistant carbon fiber epoxy resin system

Titanium replaced many steel components in the landing gear and engine strut area in an effort to reduce weight and improve corrosion resistance.

Advanced fuselage alloy 2524 yielded significant improvements in the design properties associated with fuselage skin durability

Ti-6al-4v- provides the maximum damage tolerance properties for titanium alloys.- Also selected for landing gear components

AIRBUS

Founded on December 18, 1969

Headquartered in Toulouse, Airbus is owned by the Airbus Group

A global leader in commercial aircraft activities

A300 became the world’s first twin-engine widebody jet with its commercial service entry during 1974

The flagship A380.

AIRBUS A380

A380 will ensure considerable weight savings despite the aircraft’s prodigious spaciousness

Design criteria are different for metallic and composite structures

Numerous years of successful experiences at designing metal structure cannot be directly transferred to composite structures

The A310 was the first production aircraft to have a composite fin box

The A320 was the first aircraft to go into production with an all-composite tail

About 13% by weight of the wing on the A340 is composed of composite materials

A380 will be the first aircraft ever to boast a CFRP (Carbon Fibre Reinforced Plastic) composite central wing box, representing a weight saving of up to one and a half tonnes compared to the most advanced aluminium alloys

THE TEJAS

CFC materials for up to 45% of its airframe, including in the fuselage (doors and skins), wings (skin, spars and ribs), elevons, tailfin, rudder, air brakes and landing gear doors

Both lighter and stronger 

Fewer joints or rivets, which increases the aircraft's reliability and lowers its susceptibility to structural fatigue cracks.

40% reduction in the total number of parts compared to using a metallic frame

Helped to avoid about 2,000 holes being drilled into the airframe

The aircraft's weight is lowered by 21%

Shorter time required to assemble the aircraft

LOCKHEED MARTIN

Design for extreme environmental conditions

Withstand the high temperatures of a jet engine or speeds in excess of 1,000 miles per hour

Stronger, lighter and more affordable.

Lockheed Martin’s APEX, or Advanced Polymers Engineered for the Extreme,

APEX thermoplastic nanocomposites are lighter-weight, flexible materials designed to replace machined aluminum parts in aerospace platforms.

APEX has affordable manufacturability, high mechanical and thermal performance, and excellent physical properties.
