The 3 green safety plugs were removed and replaced with red arming plugs once over the target area. This armed the weapon. The green plugs blocked the electrical path to the arming circuit, timer, barometric and radar triggers. This was a necessary safety feature as there were fears of possible detonation, either on take off or in flight. The plugs weren't removed on deployment. Great video though of a fascinating part of history.

300 m/s second is a fairly low speed for shooting the uranium rings into the uranium plug (wonder why not shoot the smaller plug into the rings?!). The faster they are shot together, the more complete the fission reaction thus more power yield. I read that only less than 5 percent of the total uranium actually went fissile in Little Boy, the rest was wasted. Fat Man had extremely high speed explosive lenses in the 8K m/second range for the fastest possible implosion.

The “Silverplate” B-29’s also had the aft bomb bay removed and the forward bomb bay length increased (to handle the longer atomic bombs (the very first had the front and rear bomb bays merged)). The forward bomb bay was fitted with Lancaster “Grand Slam” bomb shackles (and dropped “Grand Slams” on practice missions over Japan (along with “Pumpkins” (impact fused non nuclear versions of the Fat Man bomb))). The orange painted pumpkins acted as both practice weapons, blast bombs and security cover for the visually identical Fat Man bombs (yes, bombs plural - 15 were built before they were superseded by the Mk4 replacements in late 1946 (11 by the end of November 1945)).

@@allangibson8494 The only B29 built with a single set of bomb bay doors was made to do aerodynamic development of the "Thin Man" bomb casing. Thin Man was the original gun-type bomb designed for use with plutonium. The Thin Man bomb was 17 feet long which is why the modified B29 was needed. When the first reactor made plutonium became available it had Pu240 in it and a gun design would have caused a fizzle (pre-detonation). When the plutonium bomb design was changed to implosion, the single bomb door was not needed as both Little Boy and Fat Man would fit into the front bomb bay of a B29. The rear bomb bay was then used for carrying additional fuel extending the range of the airplane. None of the Silver Plate bombers used the single-door configuration, they had two sets of bomb bay doors. You can reference both “B29: The Superfortress,” by Carl Berger, and “Atom Bombs: The Top Secret Inside Story of Little Boy and Fat Man,” by John Coster-Mullen for this information.

The acknowledged difficulty with the Fat Man was the timing and relative strengths of all the charges for the implosion. For it to work correctly - ie not to end up with the core being spat out - the timing and strength of each charge had to be perfect. The development of all this consumed a lot of time, effort, and expenditure and there were doubts until the very end if it would work. The Trinity test proved that it did. The gun type was much simpler in concept and to manufacture.

With respect little boy was exponentially less efficient. Also keep in mind that U-238 or plutonium does not naturally occur on earth or anywhere. It has to be made by enriching U-235 to an atomic weight of U-238. So in essence the natural progression to initiate a larger output of energy is implosion. Lucky for the physicists at los alamos someone was working on changing the the shockwaves of conventional explosives from concave to convex and thus changing the process of how they split the atom and more efficiently changed history. A machined hollow sphere of approximately ten pounds of plutonium was compressed by hundreds of pounds of composition b which is now c-4/symtex. And boom. You get a little less than 200k lbs of tnt. What is really interesting is the incorporation of tritium and other elements and stryofoam that Teller figured out would give us the fusion bomb. Which I think Oppenheimer and the physicists at Los Alamos already knew about given the outcome of their math.

Great animation! It's amazing to me that they never tested this type of bomb because they didn't have enough enriched Uranium. They just presumed it would work. The trinity test, arguably the first nuclear bomb, used a plutonium/fat man type bomb. The first nuclear reactor was made several years earlier, and a few more were made to produce the plutonium. These reactors heated the Columbia river without producing electricity. It's hard to make a nuclear bomb that doesn't fizzle, blowing itself apart before the chain reaction has a chance to do much damage.

The polonium initiators were used to increase the amount of neutrons available for fission, helping to ensure a chain reaction.
@buckhorncortez
Жыл бұрын
The initiators were made of polonium-210 and beryllium-9. Polonium emits a constant stream of alpha particles. When an alpha particle strikes a beryllium atom it causes the beryllium to emit a neutron. The initiator for the two atomic bombs was called "The Urchin." It had a small pellet of beryllium in the center, surrounded by a shell of layers of polonium and beryllium. The beryllium was shielded from the polonium by either nickel or gold plating or foils. When the initiator was crushed it mixed the beryllium with the polonium causing a shower of neutrons to start the chain reaction. This is important as the fission reaction automatically stops when it reaches 1.12 times the radius of the mass when the reaction started. The more U235 atoms that fission simultaneously when the reaction begins, the larger the final yield.
@JackHudler
Жыл бұрын
@@Aitelly it was very much necessary. The gun bombs had a major weakness. Premature initiation. The chain reaction only takes about 100 ns to initiate. Once started the projectile will never reach the Polonium, thus the bomb yield will be low (dirty bomb), and Hiroshima would probably be uninhabitable today. So they made the decision lower the mass of the leading rings, save one. Thus they needed to make sure to artificially stimulate the initiation to reaction with Polonium-210. The bomb would work without the Polonium, but they built-in safeguards to make sure.

I had an exciting experience when, while building a yield, I lost grip of a target ring (they are super heavy) and it slammed onto another ring. Ooooo, what a flash and spark.

There were at least 2 cases of an accidental reaction in the labs after ww2. Google "tickling the dragon's tail" or something like that. They had some "cowboy" nuclear physicists who were clowning around with plutonium and graphite and accidentally set off a couple of reactions which killed and maimed several researchers.

Were there failsafes and redundancies to ensure that the firing mechanism would go off and initiate the explosion? I imagine a worst case scenario from a military perspective would be literally delivering a fully completed nuclear weapon to Japan so they could reverse engineer it and build their own

Thin Man was supposed to use plutonium but plutonium is too unstable and the nuclear chain reaction would have started prematurely, destroying the weapon without generating adequate yield, so they scrapped it in favor of the implosion design for plutonium and restricted the gun type design to use uranium only.

Great animation! Overall very good. Just a couple of possible corrections (according to what I have read in other sources, particularly Richard Rhodes' book The Making of the Atomic Bomb). The barometric switch closed at about 8000 ft (2440m) and brought the Archie radar altimeter units on-line. There were four radar altimeter units, and any two of them sensing the proper altitude for detonation (1900 ft, or 580m) would fire the bomb The polonium initiators were not strictly necessary (the spontaneous fission rate of U-235 should have been sufficient to start the chain reaction when a supercritical mass had been assembled), but Oppenheimer supposedly added them at the last minute to hedge his bets. The B-29s used for the atomic strikes were not standard-issue aircraft, they had been modified to the so-called Silverplate specification which, among other things, removed defensive armament except for the tail guns. But these are minor details in an otherwise excellent presentation.

Because the gun type was a simple project, although little effective, only about 1 KG of 65 KG of Uranium effectively start the chain reaction. The abandoned "Thin Ma"n was similar gun type, but require a high velocity "gun" and the Poloniun was subject to pre detonation, destroying the bomb before the effective explosion. When the Uranium became available in sufficient quantity they create the "Little boy". This type of bomb was to be abandoned, but issues with Poloniun production in 1946 lead to construction of dozen of "gun type" bombs as add hoc solution.

Great animation! You could have explained how those protons ejected during the fissile process had to hit other nuclei to create the chain reaction. One of the problems The Manhattan Project had to solve involved the reduction of free protons unable to hit further nuclei. Also, it would have been informative to mention the 77,000 generations of fission that take place in a super-critical mass, of which only the last 11 are the flash and heat of the expolsive force. Other than these minor comments, a great job! Given that the world is so close to nuclear war at the moment, it would have been beneficial to look at the Japanese survivors and their horrific wounds and illnesses. Please remember that these bombs are minuscule compared to the fusion weapons of today!

Slight correction here: The bomb wasn't "dropped" from the plane. It was thrown out of the bottom of the plane using inertia as the plane needed some time to get away before the bomb detonated. The plane dived then quickly pulled up and at the point it turned away the clamps were released throwing the bomb up and then away from the plane. The plane was already heading in the opposite direction by the time the bomb began dropping toward its target.

your question: •why old radars are curved and why new radars are flat "" this is about the display unit of the radar system. older radar displays were analog CRT tubes that were made with a curved surface so an electron "gun" at the back could shoot electronics that strike phosphors on the surface of the curved tube. newer displays: the introduction of digital displays made using flat sheets of glass reduced bulk and increased display resolution.

almost. the B-29 came off the production line in Sept. 1942 and operations over Japan from mid-1944. many bombing flights over Japan and a few modifications made. the issue about Lancasters only arose due to the bulk of the atomic bombs . at 3+ meters long the positioning in the bomb bay of a standard B-29 would run into an internal support strut. so the B-29 Silver Plate was created to allow for the long size and other changes for the atomic back blast expected.
