Often asked: Aviation What Are Guy Wires?

Are guy wires dangerous?

Guy wires are support structures that are anchored into the ground, to keep poles and energized conductors from falling, or sagging too much. They do not carry power, and, therefore, do not create an electrical hazard, unless poorly maintained. Still, it’s never safe to touch a guy wire.”

What is the wire on top of old planes?

It’s to basically keep the airframe together, especially on biplanes. As time passed, engines became more powerful, and airframes became sturdier in consequence. With that, the wires were less and less needed, and then you can see modern jets lack them completely.

IS IT guy or guide wire?

Guy wire goes by several names. Some refer to it as guyed wire, others guy cable, and still others guy strand or guy anchors. People will also mistakenly refer to it as guide wire, when in fact the term is derived from the term guy, which is a rope, cable or cord used to steady, guide or secure.

Can you touch guy wires?

Guy wires are not energized, meaning there’s no electricity pulsing through them. So please remember, even though guy wires are not supposed to be energized, you never know. Therefore, DO NOT touch the guy wires – or any power wires for that matter.

Why do they call a guy wire a guy wire?

The name guy wire is derived from the term guy: defined as a rope, cord or cable used to steady, guide or secure something. Guy wire is a tensioned cable that is both lightweight and strong. Guy wire is designed to work with several fittings and components making it ideal for many different uses.

Who was the first woman pilot to die in a crash?

Clark was the first American woman to die in an air accident, preceding Harriet Quimby’s death by two weeks. She was also said to be the first licensed woman pilot to die piloting an aircraft.

Why do airplanes have wires?

It connects the wings, what we see externally, to the fuselage and has to transfer all of the load – all of the weight of the fuselage against the lift of the wings, as well as the dynamic loads, bending moments, etc.

Why do some planes have a wire?

Wire cross-bracing was extensively used to stiffen such airframes, both in the fabric-covered wings and in the fuselage, which was often left bare. Routine rigging of the wires was needed to maintain structural stiffness against bending and torsion.

What angle are guy wires?

Ideally, the guy wires should extend out from the mast at a 45° angle, and should be anchored in screw eyes placed 120° apart (Figure 2). (If four guy wires are used, they should be anchored in screw eyes 90° apart.)

How tight should guy wires be?

Rohn specifies that guys should be tensioned to 10% of the breaking strength of the guy size that is recommended for a particular tower. One rule of thumb is 8% if the guy is out at 100% of tower height, 10% ifat 80% of tower height (standard Rohn drawings) and up to 15% if the anchor point is at 65% of tower height.

What is a wire stay?

Stay Wires are galvanized steel wire strands that are used for sustaining mechanical load. Generally they are made up of 7 wires stranded around 1 wire, twisting 7 wires together. A common use for stay wires is in the electricity industry, using the wire to stay power poles and tower structures.
