What is the hump on Southwest 737?
What it is for? It is called a radome, a portmanteau or fusion of the words radar and dome, which in this case houses an antenna for access to inflight Wi-Fi, and offered as an option by aircraft manufacturers.
Do all Southwest planes have winglets?
Today, most of our aircraft are equipped with winglets, the vertical fins on the tips of a plane’s wings. Winglets help Southwest save fuel, reduce emissions, and get our Customers to their destinations more quickly.
What is under an airplane wing?
The turbine engines, which are located beneath the wings, provide the thrust to overcome drag and push the airplane forward through the air. Smaller, low-speed airplanes use propellers for the propulsion system instead of turbine engines.
What are the things on the bottom of plane wings?
They are called flap fairings. They protect the flap retraction and extension mechanisms from elements and makes the aircraft more aerodynamic by reducing the amount of interference drag acting upon the aircraft.
What was the vertical fin on a 737 used for?
It was mostly used in older aircraft, which used them in trans-oceanic flights or in areas without UHF or VHF communications facilities.Modern 737s (and other aircraft in general) have done away with them. On later versions it was fitted in the leading edge of the Vertical fin of B737-200s, as shown in the figure below.
What kind of trusses are used in aircraft fuselage?
Often used in lightweight aircraft, a truss structure fuselage is typically made of welded steel tube trusses (though it can also be made of wood). They are often rounded and feature lightweight stringers to achieve a greater aerodynamic shape.
Which is the best description of a geodesic fuselage?
Geodesic fuselage structures are lightweight, strong, and ultra-durable. They were typically made of either wood and/or aluminum, featuring a fabric covering the shell for greater comfortable and aesthetic value. In the monocoqne shell structure, the fuselage is designed within the aircraft’s primary structure.
Where is the HF antenna on a 737?
It is the HF antenna. It was mostly used in older aircraft, which used them in trans-oceanic flights or in areas without UHF or VHF communications facilities.Modern 737s (and other aircraft in general) have done away with them. On later versions it was fitted in the leading edge of the Vertical fin of B737-200s, as shown in the figure below.
