What are the pods on a 737 wing?
What are the pods on a 737 wing? The large pod-like structures under the aircraft wings are called Flap Track Fairings (FTFs). Sometimes known as the trailing edge fairings, the primary purpose of the FTFs is to enclose the actuation mechanism of wing flaps.
Why do jets fly at 35000 feet?
The biggest reason for flying at higher altitudes lies in fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed. Less wind resistance, more power, less effort, so to speak.
What are pylons under airplane wings for?
A pylon connects the engine to the airframe of an aircraft. This design uses air passing through the pylon to actively disrupt the jet engine exhaust stream after it exits the engine, disrupting and redistributing the axial and azimuthal distributed sources of jet noise from the aircraft.
Why do planes not flap their wings?
Short answer: Because planes are larger than birds. Flying by flapping their wings works very well for birds and insects. Machines that fly this way, known as ornithopters, have been built, some large enough to carry a man. But larger than that and the laws of physics become a serious problem.
Do flaps go up or down for takeoff?
On takeoff, we want high lift and low drag, so the flaps will be set downward at a moderate setting. During landing we want high lift and high drag, so the flaps and slats will be fully deployed.
