How Ak47 Works

 The ak-47 was invented by the russian

weapon designer kalishnikov in the 1940s

it is the most iconic and widely used

assault rifle in the world

the shooter aims with the help of rear

and front sight



the sight leaf which represents the rear

sight

is available in 800 and 1000 meter

versions

the maximum effective range is between

300 and 400 meters

the standard magazine has 30 rounds and

is

curved the magazine can be removed via

the magazine catch



The safety lever is used to make the

firearm safe

loading the weapon is not possible in

this position

the safety lever allows the shooter to

choose between semi-automatic and

fully automatic firing mode


in the middle position the safety lever

blocks the disconnector

in the uppermost position trigger and

disconnector are blocked

in the lowest position trigger and

disconnector can move freely

as soon as the trigger is pressed the

hammer is released

the disconnector catches the hammer

after firing

the trigger must be released before

another shot can be fired

the hammer is then immediately caught by

the trigger

and the gun is ready to fire again in

fully automatic firing mode

the hammer can move freely until the

trigger is released

ak-47 and akm are assault rifles with a

rotating bolt locking mechanism

here the bolt rotates to lock and unlock

via two locking lugs

the firing pin can slide back and forth

within the bolt

the retaining pin prevents the firing

pin from sliding too far backwards

the front trunnion connects the barrel

and the receiver

it has recesses for the bolts locking

lugs

the contact points are marked in red

when the bolt rotates it is unlocked so

that it can slide

back and forth

the bolt is rotated through the cam

guide machined into the underside of the

bolt carrier

marked red here

as soon as the bolt carrier moves the


bolt rotates let's take a look at what happens when

the trigger is pressed

the hammer is released which drives the

firing pin

against the primer of the cartridge

the propellant is ignited accelerating

the bullet

the gas piston is pushed back by gas

pressure

that is why this type of reloading is

called gas

operated reloading let's have another

look at it

the gas piston is connected to the bolt

carrier

so the bolt carrier is pushed back

unlocking the bolt

and moving it backwards with the help of

the extractor

the bolt locks the case and ejects it

through the ejector

the hammer has been pushed down by the

bolt carrier and

is then caught by the disconnector the

tensioned recoil spring pushes the bolt

carrier forward

this causes the bolt to feed a new

cartridge into the chamber

finally the bolt is locked



as soon as the trigger is released the

rifle is ready to fire again

in fully automatic mode the auto seer

comes into play

the auto seer makes sure that the breach

is locked before the hammer depresses

the firing pin

the auto sear is tripped by the bolt

carrier

the akm was equipped with a muzzle brake

gas pressure coming from the barrel

pushes the weapon down to the left

preventing unwanted rising of the barrel

How Nuclear power plant works

Image
  On a December afternoon in Chicago during the middle of World War II, scientists cracked open the nucleus at the center of the uranium atom and turned nuclear mass into energy over and over again. They did this by creating for the first time a chain reaction inside a new engineering marvel: the nuclear reactor. Since then, the ability to mine great amounts of energy from uranium nuclei has led some to bill nuclear power as a plentiful utopian source of electricity. A modern nuclear reactor generates enough electricity from one kilogram of fuel to power an average American household for nearly 34 years. But rather than dominate the global electricity market, nuclear power has declined from an all-time high of 18% in 1996 to 11% today. And it's expected to drop further in the coming decades. What happened to the great promise of this technology? It turns out nuclear power faces many hurdles, including high construction costs and public opposition. And behind th...

How Iron dome works

Image
 the Iron Dome missile defense system first detects and tracks incoming threats within a 100 kilm range using radar it then transfers this data to the battle management control system and the launcher which relay it to the Interceptor when a specific threat is confirmed an interceptor missile is launched to destroy the incoming rocket before it reaches the predicted impact area the interceptor missile uses its Electro Optical sensor to track and Target the incoming Rockets aiming to get as close as possible to intercept them effective ly we will also look at the basic parts of the Tahir and how it works in step-by-step formats and not to forget a short comparison with the Kasam and the Iranian built grad Rockets all in the videos ahead so stay tuned and don't miss a beat the Iron Dome system comprises of three Central components number one battle management and weapon control number two missile firing unit number three detection and tracking radar while a t...

How jet Engines Works

  How jet engine works. jet propelled airplanes use a turbofan design the turbofan can be thought of as a high-tech propeller inside of a duct called a diffuser driven by a gas generator the core the core of a jet engine is a gas generator that creates high-pressure gas to power a turbine this setup has compressor combustor and turbine sections the compressor compressed air makes for a much more powerful combustion reaction relative to engine size compression happens in stages that force incoming air into an increasingly narrow chamber a single compressor stage is comprised of a spinning rotor paired with a ring of stationary stator veins which are attached to the core casing rotor blades swirl the air as they force it through the compressor stator vanes slow this swirling momentum in exchange for increased air pressure the compressor has four low-pressure and ten high-pressure stages the combustor air is mixed with fuel and ignited as it passes through the...
