NettetThe implosion-driven launcher (IDL) uses the linear implosion of a pressurized tube to shock-compress helium gas to a pressure of 5 GPa, which then expands to propel a projectile to... The Pu-239 pit of Fat Man was only 9.1 centimetres (3.6 in) in diameter, the size of a softball. The bulk of Fat Man's girth was the implosion mechanism, namely concentric layers of U-238, aluminium, and high explosives. The key to reducing that girth was the two-point implosion design. [citation needed] Two … Se mer Nuclear weapon designs are physical, chemical, and engineering arrangements that cause the physics package of a nuclear weapon to detonate. There are three existing basic design types: • pure … Se mer The next step in miniaturization was to speed up the fissioning of the pit to reduce the minimum inertial confinement time. This would allow the … Se mer While every nuclear weapon design falls into one of the above categories, specific designs have occasionally become the subject of news … Se mer Nuclear fission separates or splits heavier atoms to form lighter atoms. Nuclear fusion combines lighter atoms to form heavier atoms. Both … Se mer The first task of a nuclear weapon design is to rapidly assemble a supercritical mass of fissile (weapon grade) uranium or plutonium. A supercritical mass is one in which the percentage … Se mer Pure fission or fusion-boosted fission weapons can be made to yield hundreds of kilotons, at great expense in fissile material and tritium, … Se mer All the nuclear weapon design innovations discussed in this article originated from the following three labs in the manner described. Other … Se mer

NettetLinear implosion is one of those places. GWH, I have great respect for your work, I've seen your posts in many places. Unfortunately, I still haven't seen one shred of evidence to support linear implosion from the DOE, or UK Ministry.

W79 - Linear Implosion
NettetThat the compression of the fuel shell and the majority of the acceleration of the capsule inward overlap can be seen from the following consideration. When the shell has imploded to r=0.8 (from r=1.0) half of the work has been done on the secondary and it has acquired 70% of its final implosion vlocity. Nettet1. jan. 2013 · Using detonation wave-shaping techniques, this programmed linear implosion can be used to gradually accelerate the projectile to velocities faster than … NettetBuilding implosion, which reduces to seconds a process which could take months or years to achieve by other methods, typically occurs in urban areas ... Linear shaped charges are used to sever steel supports. These explosives are progressively detonated on supports throughout the structure. emily duval fsu
