Oppenheimer Atomic bomb How it Works | First Nuclear Bomb

on August 6 1945 this American B-29 bomber four propeller plane named the Enola Gay left the island of tinian for Hiroshima Japan carrying the uranium-235 gun type bomb named little boy little boy was one of the first nuclear weapons tested on mankind while the dangers in the engineering behind it were even regretted by the scientist Oppenheimer Julius Robert Oppenheimer was born on April 22 1904. he worked on the Manhattan Project and was often coined as the father of the atomic bomb but the interesting part was later in his life he fought to eliminate the production and development of nuclear weapons and died at the age of 62 1967. this is how the uranium projectile is launched at 300 meters per second to initiate the four polonium for an extra explosion placed on the tungsten carbide we will also be looking at the nuclear fission of the neutrons explained in super simplified animations and not to forget the different blast radius zones of this first atomic bomb so stay tuned and then don't miss a Beat as we all know the Manhattan Project produced two different types of atomic nuclear weapons codenamed fat man and little boy this is the fat man atomic bomb is a large heavy plutonium imploded using shaped charges as shown in the animations while a little boy has a less heavy uranium weapons triggered in a shotgun or gun Tech Designs the little boy has a length of 10 feet or 3 meters with a diameter of 28 inches 71 centimeters while the fat man has a length of 10 feet or 3.3 meters but a much larger diameter of 60 inches or 1.5 meters comparing this to a person will help you understand its size even better let's compare this to this classic American SUV as you see both of the nuclear weapons look small considering the amount of destructive power packed into it this nuclear weapon weighs around 4898 kilograms or 10 800 pounds while the low boy as the name suggests weights just shy of 4 400 kilograms or nine thousand seven hundred pounds before we dive into how this works we have to understand the parts of the nuclear weapon starting from the back these are the Box Tail Fins meant to stabilize the bomb when dropped from this B-29 super Fortis bomber these are the three electric gun primers primer is the device responsible for initiating the propellant combustion located here also known as the chordate or conventional charge that will push this projectile at an explosive force moving ahead this is the projectile tungsten carbide disc and the most important part is the uranium-235 hollow projectile Rings it weighs around 84 pounds or 38.4 kilograms while the front is the uranium Target rings that weigh around 56.2 pounds or 25.6 kilograms that is around 145.5 pounds or 65.5 kilograms of uranium closely note as it is very important to understand the projectile ring slugs are hollowed and designed for the Target rings to enter all these mechanisms and parts are encased in a 6.5 inch or 170 millimeter Smooth Bore gun barrel moving to the front this is the impact absorbing Anvil just above it is the tungsten carbide plug these are the four polonium initiators placed on the tungsten carbide they are kept to make sure there will be a nuclear chain reaction when it is dropped and activated moving to the top of the structure are the arming infusing equipment let's move outside this atomic bomb to understand it better these are the barometric sensing ports and manifolds the barometer helps to identify the altitude in which the bomb is located so that it can activate this Archy fusing radar altimeter which is these curvy looking objects that activates before reaching the ground just above it is the electric plug and some refer to this as the arming wires all that destructive power requires a platform to transport this nuclear weapon the answers is this B-29 super Fortress it was also the world's heaviest production plane because of increases in range bomb load and defensive requirements Boeing built a total of 2766 b-29s super Fortress planes and it was the most advanced for propeller driven bomber of the second World War it has a length of 99 feet or 30.1 meters with a huge span of around 141 Feet 3 inches or 43 meters interestingly the plane has a gross weight of around 140 000 pounds or 63 502 kilograms and could carry a 20 000 pound bomb the Bombay door is located just below the fuselage and it can open them as shown in the animations as stated this is one of the most fortified plane in that era it can carry around 12 50 caliber machine guns and remote controlled turrets as shown in the animation two below the plane four above the fuselage two remote control turret one above and below near the Tail and the last two are located at the back of the plane and that is one protected gunship now that we've established the B-29 super Fortress as a primary transport let's take a look at how this nuclear bomb Works in basic step-by-step format step number one before opening the Bombay doors all three arming plugs are pulled one after the other by the weapon air William Sterling Deke Parsons step number two the doors open and the bomb Falls due to gravity then it switches to its internal 24 volt battery and starts the timer after 15 seconds the bomb would be approximately 3 600 feet or one thousand one hundred meters away from the aircraft step number three the barometer senses the desired height of around 580 meters or 1900 feet as the little boy was designed to be an air burst above the ground the membrane closed his circuit activating the multiple radar altimeters located at the front of the bombs the barometric stage was added because of a worry that external radar signals might detonate the weapon too early step number four to ensure accurate detection of final altitude multiple radar altimeters were utilized this process involves measuring the altitude above the ground beneath the aircraft or the little boy through the timing of radio waves travel reflection and return once the correct height was sensed the firing switch activates step number five this ignites the three Navy gun primers in the breech plug step number six this sets off the charge consisting of four silk powder bags each containing two pounds or 0.9 kilograms of cordite step number seven the uranium projectile will be launched at 300 meters per second toward the opposite end of the Gun Barrel step number eight four polonium initiators placed on the tungsten carbide initiate the nuclear reactions step number nine this is where nuclear fission happens the new Kyo certain heavy atoms split into smaller lighter new kite releasing excess energy in the process let's dive a little bit deeper the neutron strikes the nucleus and is absorbed the absorbed Neutron causes the nucleus to undergo deformation the nucleus fission releases an average of two or three neutrons thus creating a chain reaction or in some words an explosion the blast radius can be divided into several zones the central Blast Zone has a diameter of 0.36 square kilometers which is the extent of the firewall radius this is the epicenter and experienced almost total Destruction severe blast damage Zone extends to around 4.5 square kilometers this has severe damage to buildings High casualties and widespread destruction and radiations modern blast zone is about 8.7 square kilometers damage to buildings and radiation burn is still significant but less severe light damage zone is beyond the blast radius at 11 square kilometers here there's fires radiation exposure and psychological trauma-affected survivors among the thousands let's simplify this through these animations once the correct height is sensed the firing switch activates the three Navy gun primers ignite the charge consisting of four silk powder bags each containing two pounds or 0.9 kilograms of cordite the uranium projectile is launched at 300 meters per second at this point four polonium initiators place on the tungsten carbide initiate nuclear fission reactions in a milliseconds there will be an explosion damaging buildings and killing people by the thousands we make original 4K 3D animation with two animators working on it
