A barrel is a large barrel.
A tonneau is a large vat or barrel . This cylindrical container allows you to store different substances: generally, the barrel is used for the production and storage of wine or oil .
For example: “The price of oil per barrel reached its lowest level in the last twenty years,” “This winery can produce about a hundred barrels of wine a year,” “The boy hid in an empty barrel so that his parents wouldn't.” find it."
In the past, burning barrels were used as a projectile . Bathed in tar so that they could sustain fire for a long time, they were thrown towards the enemy or into a pit as a defense.
The barrel as a unit of measurement
In ancient times, a measure that was used on ships was called a barrel.
The barrel was equivalent to five-sixths of a ton , as detailed in the dictionary of the Royal Spanish Academy ( RAE ). Over the years, it began to be noted that a ton was equivalent to a male barrel.
A fat guy
By extension to these meanings, in colloquial language fat individuals are usually described as barrels.
“The guy is made up of a barrel, he should lose weight ” and “Marcelo is a barrel: I don't understand why he doesn't decide to start a diet to lose weight” are examples of this use of the concept.
A type of aerial acrobatics is called barreling.
The roll as an acrobatic maneuver
Tonel, on the other hand, is an acrobatic maneuver performed by aircraft in exhibitions. When an airplane performs a roll, it completes a rotation of three hundred and sixty degrees on its longitudinal axis, meaning the turn does not change the direction of the craft once it is completed.
Experts differentiate between the fast roll , the slow roll , the flown roll and the aileron roll , the main difference of which is the trajectory described by the nose of the ship with respect to a reference point that is on the horizon, although also The way the controls are used differs. There is also the one called by times . Let's see three of the main ones below.
Barrel by times
It consists of a slow horizontal rotation deliberately interrupted at equal intervals . Generally, the barrel must be divided into four or eight parts, from which it is possible to identify them as a 4-stroke barrel or an 8-stroke barrel , respectively.
spoiler barrel
It is the easiest of all. The circle described by the nose of the plane as it rotates around a reference point is small. To achieve this, the pilot must follow these steps:
- Chop gently until the speed exceeds the so-called average or cruising speed by 10%, that is, the uniform and constant speed that can be reached under normal conditions of temperature and pressure without facing alterations of any kind.
- Raise the nose quickly and begin the roll.
- Raise the pressure with the ailerons fully up and slowly move the stick forward.
- Without moving the lever from its position, reduce the pressure on the steering wheel for a moment.
- Move the lever back gently and continue until you complete the roll over the horizon.
blown barrel
This is perhaps the most popular, thanks to the StarFox video game series, published exclusively on Nintendo consoles, where the phrase "Do a barrel roll!" ( "Make a barrel roll!" ), said by one of the characters to give an indication to the main pilot, exceeded the limits of fiction to be often mentioned by fans in very diverse situations. It is important to note that the concept is not used correctly in the game, since the twist that is seen in it is different.
To make a flown barrel it is necessary:
- Chop gently until you exceed the average speed by 10%.
- Turn upwards 20º to the left.
- Start the barrel to the right.
- Give forward leverage without losing distance from the reference point.
- The ailerons should be turned all the way to the right.
- Move the lever backwards but always to the side.
- Complete the barrel below the horizon.
