What Is A Jesus Nut

Jesus nut – Wikipedia

The main rotor attach nut, sometimes known as the “Jesus nut,” from a Bell 222U is shown in hand for scale (on the left) and mounted with a locking key (on the right) (right) The main rotor retention nut or mast nut, which is used to secure the main rotor to the mast of various helicopters, is referred to as the “Jesus nut.” The related slang termJesus pin refers to the lock pin that is used to fasten the retaining nut on the retaining nut.

More broadly, the term “Jesus nut” (also known as “Jesus pin”) has been used to refer to any component that has a single point of failure and can result in catastrophic effects in some cases.

Origin of name

The nickname “Jesus nut” may have been created by American soldiers serving in Vietnam; the Vietnam Conflict was the first war in which significant numbers of soldiers were transported by helicopter. Additionally, the phrase may have originated from the PBY Catalina, which featured twoJesus bolts that secured the wing to its fuselage. If the Jesus nut fails while the helicopter is in flight, the rotor will separate from the chopper and the only thing left for the crew to do is “pray to Jesus,” which they will do.

In 2000, the mast nut of a Bell 206 B was removed so that it could be repainted, but it was not reinstalled and tested before the plane was put into flight.

Approximately 10 minutes after takeoff, the chopper crashed, killing both of its occupants.

Other contexts

The word has subsequently been used more broadly within the engineering field, to refer to any single component whose failure would result in the catastrophic failure of the entire system. An additional application of the phrase may be found in rock climbing, where it refers to the first piece of protection (some of which are also referred to as ” nuts ” ) that is set on apitch. To eliminate the chance of a “zipper,” which occurs when the outward draw on the rope from the belayer who is holding a falling climber pulls protection gear from the bottom up, this component must be set so that it can withstand both an outward and a downward force.

The word “Jesus nut” first appeared in print in Robert Mason’s novel Chickenhawk, which recounts his experiences as a pilot during the Vietnam War.

This is a Jesus nut – what kind of part is that? Why does it have such a bizarre name?

Consider a little portion of any system that is so critical that its failure would cause the entire mechanism to come to a grinding halt in a heartbeat. What would you like to call it? As a result of this, some troops who were amusing themselves nicknamed one of these parts a “Jesus nut” or even a “Jesus pin.” What exactly is that section? What was the reason for naming it that way? Jesus nut is a little, yet extremely powerful, nut. This one was taken from a Bell 222U fax machine.

  1. A lot of aviation-specific technical terms exist, but this one stands out as a little distinct from the others.
  2. The name was so appropriate, and the section is so significant, that it eventually became a meaningful method to pay tribute to retiring military personnel.
  3. Jesus nut is, very simply, nothing more than a nut.
  4. There’s no fun in calling the Jesus nut by its technical name, which is the primary rotor retention nut.
  5. According to tradition, one soldier inquired of an aircraft technician about the object in question and what would happen if it were to fall off during a flight.
  6. Because of this, the helicopter will not be able to fly at all and will instead drop to the ground like a brick.
  7. However, while the Bell 222U continues to use the Jesus nut, other modern helicopter types have alternative means of retaining the main rotor in place.
  8. It has even made its way into technical literature, and people are fully aware of what is meant by the term “Jesus nut.” Eventually, it was given as a retirement gift to military members.
  9. Many contemporary helicopters are no longer equipped with a Jesus nut.

The name, on the other hand, is not going away anytime soon because it is already being used for other critical components of many other systems. There is a distinctive Jesus nut in rock climbing equipment — it is the first piece of protection to be set on a pitch, to provide an example.

Jesus nut

The main rotor attach nut, sometimes known as the “Jesus Nut,” from a Bell 222U is shown in hand for scale, and it has been fitted with a locking key. Some helicopters, such as the UH-1 Iroquois, have a main rotor retaining nut, which is referred to as a Jesus nut or a Jesus pin. Both terms refer to the same thing. Americans serving in Vietnam may have created the phrase, as the Vietnam War was the first in which large numbers of men were transported by helicopter. Various other accounts assert that the word was first used by Igor Sikorsky, a pioneer of the rotor-wing aircraft and a very religious individual, who is credited with coining the phrase.

  1. In addition, a person’s confidence in the Jesus bolt’s ability to perform its intended function without fail is required.
  2. The pin, on the other hand, must be examined prior to the trip.
  3. Increasingly, it has evolved into a genericengineeringterm that can be used to any single component of a system whose failure would result in a catastrophic failure of the system in its whole.
  4. The Rattler/Firebird Association is a veterans’ organization founded by Vietnam War soldiers.
  5. When it comes to rear suspension bikes, mountain bikers frequently refer to this screw as the “pivot bar screw” since it keeps the rear wheel pivot bar in place.
  6. Consequently, if the screw comes loose, the pivot bar has a tendency to roll out, resulting in catastrophic rear-wheel failure and the obligatory removal of the back wheel.
  7. An additional application of the phrase may be found in rock climbing, where it refers to the first piece of protection installed on a pitch.
  8. A second advantage of the Jesus Nut is that it eliminates the risk of a factor two fall onto the belay anchor.
  9. Should this nut break, the gun tube will come out of the battery when the gun is fired, perhaps resulting in the death of the gun crew.

When it comes to radio-controlled helicopters, a derivative phrase known as the “Jesus Bolt” is used to refer to a bolt with a function that is equivalent to that of the Jesus nut in a full-size helicopter.

The Jesus Nut

According to Wikipedia, the free encyclopedia. The Jesus nut, sometimes known as the Jesus pin, is a hexagonal nut that is used to secure the main rotor of various helicopters, such as the UH-1 Iroquois, to the helicopter’s mast. Originally used by American soldiers in Vietnam, the slang phrase for main rotor holding nut has now become more formalized in the military community. In the case of a failure of the Jesus pin while in flight, the helicopter would separate from the rotors, leaving the crew with no choice but to pray to Jesus.

  1. This was the first documented instance of the Jesus pin failing.
  2. 1.
  3. More subsequently, it has evolved into a general engineering phrase that may be used to any single component of a system whose failure would result in the catastrophic collapse of the entire system as a result of its failure.
  4. ” It was one of those days when the crew chief decided enough was enough, and he stepped out of the cockpit as the Major was starting the aircraft, a Jesus Nut in his hand (Which is the one main part that holds the rotor system on the aircraft).
  5. In a fit of rage, he rushed out of the car and shouted at the crew chief.
  6. “Isn’t that Jesus Nut off of this airplane Sergeant?” said the Major, who was baffled by the situation.
  7. As a result of all of this, the Major felt extremely humiliated, and he resolved to conduct his own preflight inspections from that point forward.” The Rattler/Firebird Association, a group of helicopter veterans, awards the “Jesus Nut Award” every year.

“Jesus Nut Award” “to the member who travels the greatest distance to attend the group’s gatherings. The following is offered by another group of veterans: “Enjoy the sight and may the Jesus Nut remain tight.”

The Jesus Nut

It is not, contrary to popular belief, an abbreviation for an overly enthusiastic Christian, but the moniker given to helicopters’ primary rotor-retaining nut, which is also known as the “Jesus nut.” The nut in issue, which was most likely invented by American soldiers serving in Vietnam, was responsible for keeping the rotors firmly in place. Suppose the nut failed during the flight, the rotors would detach, and the only choice available to the troops on board would be to ‘pray to Jesus,’ who they were going to meet.

As the Apostle Paul wrote to a congregation in Colosse, he expressed his belief in Jesus by saying, “In him all things hold together.” Paul claimed that Jesus, as the Son of God, was the one who created all things and for whom all things were made, and that this was true.

Before any helicopter pilot would take a helicopter up into the air, they would check to see that the ‘Jesus nut’ was properly secured in the chopper’s frame.

The Jesus nut

When the words ‘Jesus Nut’ are used in 2019, the first thing that comes to mind is a person who either walks with Jesus or at the very least talks a lot about Jesus. There are various distinct types of common nuts used in modern engineering, each with a unique set of applications or benefits. There are several types of nuts, including the hex nut, jam nut, acorn nut, flange nut, square nut, coupling nut, wing nut, nyloc nut, slotted nut, keps nut, T nut, and castle nut. Hex nuts are the most common type of nut.

The ‘Jesus nut’ is a nut that is located on top of the main shaft of certain helicopters and is responsible for holding the rotor in place.

However, it is possible that the name originated with Igor Sikorsky and his mechanic.

They even have songs written about it.

Jesus died in our place in order to reconcile us to God.

Through prayer, we must invite Jesus into our lives and allow him to work in our lives.
