Is a 787 a composite wing?
Is a 787 a composite wing?
Boeing 787 has composite wings with raked wingtips where the tip of the wing has a higher degree of sweep than the rest of the wing. This aerodynamic design feature improves fuel efficiency and climb performance while shortening takeoff length.
What can I expect from Boeing stock?
Stock Price Forecast The 21 analysts offering 12-month price forecasts for Boeing Co have a median target of 270.00, with a high estimate of 306.00 and a low estimate of 169.70. The median estimate represents a +36.52% increase from the last price of 197.78.
What are the drawbacks of using composite materials?
Disadvantages
- GRP.
- Expensive material.
- Specialised manufacturing process required.
- High-quality mould needed.
- CARBON FIBRE.
- Very expensive material.
- Only available in black.
- Highly specialised manufacturing processes required.
Why is 787 so fuel efficient?
New, lightweight composite materials make up half of the 787’s primary structure, including the fuselage and wing. The aircraft’s wing design and construction enable speed and fuel efficiency. The 787 is powered by new, more fuel efficient models of jet engines produced by General Electric and Rolls-Royce.
Is composite material safe?
The materials most frequently used in composite manufacturing, such as matrix (polyester, vinylester, phenolic, epoxies, methyl ethyl ketone peroxide, benzoil peroxide, hardeners, and solvents), and reinforcement materials (carbon, glass and Kevlar fibers, honeycomb and foams) can be highly toxic to human body.
What safety requirements must be met with composites?
Personal protective equipment (PPE) Gloves, protective clothing, and eye protection is mandatory due to the nature of the work involving composite materials. The selection of appropriate protective equipment should be based on the type of task being undertaken and the associated risk.
Is the skin surface nonconformity on a 787 a safety risk?
The skin surface nonconformity is not deemed to pose an immediate flight safety risk and in-service 787s are not currently a target of the inspection program. The potentially affected areas of the aircraft are the carbon fiber composite inner fuselage skin near each join, where one fuselage section is mated with another.
What is Boeing doing about the nonconformity of its 787s?
As part of this inspection regime, Boeing has asked each of its fuselage suppliers to conduct similar inspections for the nonconformity at their facilities, says a Boeing spokesperson. The skin surface nonconformity is not deemed to pose an immediate flight safety risk and in-service 787s are not currently a target of the inspection program.
How will the Boeing 787 affect labor costs?
With the expanded use of composites and titanium combined with greater discipline in usage of aluminum, Boeing expects the 787 to have much lower nonroutine labor costs than a more conventional metallic airframe.
Are there any problems with the Boeing 787 Dreamliner?
The Boeing 787 has been involved in five noteworthy accidents and incidents as of April 2020, with an overall safety record of zero fatalities and zero hull losses so far. Operational problems. A Japan Airlines (JAL) 787 experienced a fuel leak on January 8, 2013, and its flight from Boston was canceled.
