What do wing slats do?
Slats are extendable, high lift devices on the leading edge of the wings of some fixed wing aircraft. Their purpose is to increase lift during low speed operations such as takeoff, initial climb, approach and landing. Slats are most often extended and retracted using hydraulically or electrically powered actuators.
What is a wing fillet?
A streamlined fairing between a wing and the fuselage to smoothen the airflow and to minimize interference drag. Pronounced “fill-it.” See also fillet.
Why are slats needed to build a successful wing?
Slats are a form of high-lift device, just like trailing-edge flaps. They alter the shape of an airplane’s wing to help it produce more lift at low airspeeds. Slats are found on the wing’s leading edge, and they move forward to increase the camber of the wing.
What are the spikes on plane wings?
If you’ve ever wondered what the little metal rods sticking out of the back of the wings are, they’re known as static wicks, or static dischargers. Their role? To prevent lightning strikes from having an affect on the aircraft. “Statistically, each aircraft is struck by lightning on average once a year.
What is the meaning of tapered wing?
A wing planform in which the chord of the wing changes continuously from the center of the wing to the wing tip. In addition, this may be accompanied by a taper in the depth of the airfoil. A tapered wing has advantages from structural and aerodynamic points of view. See double taper.
How does the Yehudi increase the height of the wing?
Apart from covering the landing gear leg the Yehudi also increases the wing root cord which allows the build height for the root to increase for the same wing relative thickness. This is useful as the wing has its highest stresses in this area, it is where the wings bending moment is at its highest.
When was the Yehudi extension added to the Boeing 707?
This extension, called the Yehudi, was added to ease landing gear integration in the wing root for low wing airliners from the mid -1950’s. The Boeing 707 was one of the first examples.
What is the purpose of the wing area?
Wing area serves the same purpose of enabling the comparing of e.g. the max lift per square meter of wing surface between e.g. the Boeing 787-9 and Airbus A350-900 even though these are not the same size aircraft.
