How it Works Fat Man Oppenheimer Trinity Atomic Bomb

Oppenheimer Trinity test marked the Inception of the implosion design plutonium eventually leading to the detonation of the fat man Atomic weapon over Nagasaki the outer charge explodes inward followed by the inner ring of explosives creating a concave shock wave it moves to the aluminum Pusher breaking the barren plastic sphere the shock waves continue toward the uranium-238 it travels further compressing the plutonium sphere and compressing it more interestingly this was James tuck idea a British physicist who suggested employing ship charges as three-dimensional explosive lenses but it was further developed and perfected by Von Newman Hungarian American mathematician physicist and computer scientist so stay tuned as we move to explore the step-by-step process of how this fat man Atomic weapon work all in the videos ahead so don't miss a Beat starting from the back this is the California parachute tail it was meant to stabilize the weapon when dropped next we have the Barrow 2 collector which helps measure the altitude of the bomb this section contains the Barrow switches radar and timers moving further ahead these are some of the 32 Detonator wires connected to this x unit the firing set placed near the charge these are the 24 volt batteries required to detonate the charge surrounding the nuclear components moving to the exterior of the weapon are these free arming plugs removed before dropping from the B-29 plane these are the four Archie radar antenna that activates when the bond reaches a suitable height finally at the front we find the 4A and destruct fuse this device was made to self-destruct the weapon so as not to fall into the hands of the enemy when each of the firing mechanism fails to activate let's dive into the interior of this weapon the core of the assembly is the internal Neutron initiator this is responsible for emitting neutrons essential for the Chain Reaction it contains a beryllium palette and a beryllium shell with inward pointing spikes and between them is polonium a radioactive substance emitting alpha particles the entire Neutron generator assembly is two centimeters in diameter surrounding the neutron generator is the main fusion material around 6 kilogram plutonium sphere measuring around 9 centimeters in diameter enclosed within this sphere is another concentric sphere made of uranium-238 acting as a neutron reflector to increase fission efficiency and contribute to the fission reaction on the uranium sphere lies a thin layer of plastic shell made of acrylic thermoplastic enriched with boron its purpose is to absorb slow-moving neutrons and prevent predetination the critical components for the fission reaction are enclosed in a thick layer of aluminum known as an aluminum Pusher which uniformly transfers shock waves from the explosives to the uranium The Pusher sphere of aluminum is surrounded by 32 blocks of faster explosives a combination of 61 RDX and 39 TNT an additional layer of 32 explosive blocks lies outside forming an explosive lens to shape the detonation wave each explosive block contains a Detonator for initiation this assembly is referred to as the physics package encased in a fixed steel case to contain the explosion of fast and slow explosives simultaneous detonation of all explosive blocks is crucial for a symmetric explosion lastly the x-unit an electronic component with capacitors produces High current high voltage and distributes it simultaneously to all 32 detonators via wires with thick insulation let's look at the basic step-by-step process step number one Boeing B-29 Superfortress acts as the primary transport step number two before opening the Bombay doors all three arming plugs are pulled one after the other step number three the doors open and the bomb Falls due to gravity then it switches to its internal 24 volt battery and starts the timer step number four after 15 seconds the barometer senses the desired height the membrane closes 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 five to ensure accurate detection of the final altitude multiple radar altimeters were utilized this process involves measuring the altitude above the ground beneath the aircraft or the fat man through the timing of radio waves travel reflection and return step number six once the correct height was sensed the x-firing switch activates and sends signals through the 32 wires to set Bridge charge detonators step number seven the outer faster charge explodes inwards followed by the inner ring of explosives creating a concave shock wave step number eight it can travel to The illuminum Pusher breaking the baron plastic sphere step number nine the shock waves further travel towards the uranium-238 step number 10. this makes the plutonium sphere denser compressing it further in the process step number 11. this is the final part of the process where the extreme forces crushed the beryllium shell and the polonium releasing neutrons required for fission reaction 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 we make original 4K 3D animation from scratch with two animators working on it full time so please support us by subscribing and dropping in a
