The segment that attaches the wing to the fuselage?

Question

I've heard people call it the strut, the pylon, the fairing, etc etc. What is this really called?

Answer 1

I've always heard strut.

Answer 2

aviophage had the best answer so far.  The fairing is for aerodynamics only and non-structural.

Other aircraft used the pylon to attach the wing, the last I can think of was the PBY Catalina of WWII fame.

Still others, the T-6 and DC-3 have a center section with a flange at the outer ends.  The outer wing panels likewise have a flange and they bolt together.  168 bolts on the T-6 since I bought new ones from Lance as part of the recent AD complaince (wing separated at a fighter pilot for a day outfit pulling assymetric gs).  These all have a torque value and are generally covered with another aerodynamic fairing.

Answer 3

Avophag said it perfectly correct.

Answer 4

The part of the plane is called the strut. Fairings are what are used to actually put it together. Pylons are what are attached to the wings or under the fuselage to support the engines, weapons, or whatever else the aircraft needs to carry. Hope this helps

Answer 5

Are you referring to the bar that goes from the wing to the bottom of the fuselage?  It si a strut.

Answer 6

There are a number of ways of attaching wings to a fuselage.  The strut is not part of the attachment, but only an external strengthening member that allows the wing attachment points to be more lightly built.

Most light airplanes have a "pass-through" which is a hollow beam integral with the fuselage structure and into which the inboard extensions of the wing spars are inserted and bolted in place.

If the airplane has wing struts, the attachment points can be less heavily built, because the strut reduces the up/down motion possible for the wing.

Most light airplanes, including your Cessna 152, most Piper airplanes, and most Beechcraft, have a fairing of some kind to seal the joint between the wing and the fuselage.  The purpose of the fairing is to reduce drag.

A pylon, in an airplane structure, is something different.  Look up "Ryan PT-22" for a good example of a pylon.  The pylon is a sort of tower that sticks up from the fuselage and serves as an attachment point for bracing wires that stiffen the wings.  No airplanes have been made that way since the 1930s.

The term "pylon" is also used to refer to the struts or brackets that attach engine pods under the wings.  Most pilots and ground crews call them "brackets."

Larger airplanes are often made with a wing that is divided into three parts:  the two outboard wings, and the section that is bolted to the fuselage, which is called the "center section."

The center section is a heavily constructed, complex assembly that secures the outboard wing sections and may contain any combination of landing gear, auxiliary equipment, fuel tanks, and major structural members.

See the answers to your prior question about the "box."  Part of the Center Section is sometimes called the "box section."  Not all large airplanes have the kind of structure shown in the picture.

Answer 7

There are 2 different assemblies that are attached together . The fuselage and wing Assembly . The fuselage is tied into what they call the center wing box by the ways of the frames off the fuselage tied into angles off the wing box. They call it fuselage to wing attach point frame or angle.or stiffener or skin. It all depends which area your trying to define. Dc9 ,MD88 ,727. fuselage frames  ties into angle  on the wing box that runs left to right. Then they have a angle that runs forward to aft that ties the wing box to the frames and skin. In the forward and aft ends of the wing box the stringers or longerons tie into a t.cap .

Answer 8

hinge.

edit> sorry for misinforming, i used the same term we use for attaching of the rotor blade /i am a helicopter pilot/ thus, like calnickel said, the hinges do NOT support bending of the wing, while the assembly/or flange/+bolts support the bending of the wing.

each beam has its own assembly, who has its opposite lock at the fuselage and both are linked by a bolt. usually a common wing is attached by one assembly using two bolts, which provides support for the bending motion / bolt are placed along the longitudinal axis/, with supplementary hinge at the supportive beam.

if the wing is manufactured as a monocoque construction, the

bolts and flanges/assemblies are replaced by either simple glueing or riveting the wing structure to the fuselage.

struts only support the stability of the wing. all struts are still attached to the construction beams through hinges.

Answer 9

On the C130 and C141, they are called rainbow fittings. There are arches formed into the casting that resemble little rainbows to allow for the hardware to be installed and torqued down. The bolts are re-torqued at specific intervals.

Answer 10

Fittings.  Specifically, wing to fuselage fittings, fuselage to wing fittings, and wing bolts.

A strut braces the wing (keeps it from flapping or in the case of a jury strut, keeps the wing from twisting).  But it cannot support or attach the wing by itself.  The Cessna 172 has struts, but it also has fittings at the wing roots and upper fuselage.

A pylon is for an engine or nacelle mounting, I've never heard the term used for aircraft wing attachment (although the Consolidated Canso/Catalina's wing might be considered a pylon).

A fairing is typically a non-structural part that smooths the airflow between the fuselage and wing to reduce interference drag.  It might be structural on some composite aircraft (like the Rutan Varieze) but the wings are attached outboard of the fairing.

Hinge isn't really a universal term.  Although most airliners allow the wings to flex on four bolts (two on each side) and they act like hinges, there are many aircraft that aren't built this way.  The Piper Cherokee for example has a couple dozen bolts attaching each wing and they do not act like hinges.  Instead the wing simply bends under load.

Answer 11

Are you talking about the large round pipe coming out of the wing that goes into the fuselage?  Thought that was the spar.

Answer 12

It is a strut.

Answer 13

It's called the Wing Root.
