What are 777 wings made of?
Instead of aluminum, boeing will make the new wings out of carbon-fiber composites, which are stronger and lighter than the metal they replace. That technology helps enable the company to extend the width of the wings by 23 feet (7 meters), or 11 percent beyond the existing 212 feet. The significant wing flex observed on the boeing 787 is a deliberate product of its carbon-composite construction, which allows for greater elasticity than traditional aluminum airframes.
What are the 4 types of flight?
Flight comes down to four fundamental forces: lift, weight, thrust, and drag. Each force has its own direction, opposing force, and factors that affect its strength. An airplane has four main forces that act on it: thrust, drag, lift, and weight.
