The adjacent photograph shows two unusual phenomena: bright spikes projecting from the bottom of the fireball, and the peculiar mottling of the expanding fireball surface. The surface of the fireball, with a temperature over 20,000 Kelvin , emits huge amounts of visible light radiation , more than 100 times the intensity at the Sun's surface.
The ASM-A-1 Tarzon, also known as VB-13, was a guided bomb developed by the United States Army Air Forces during the late 1940s. Mating the guidance system of the earlier Razon radio-controlled weapon with a British Tallboy 12,000-pound (5,400 kg) bomb, the ASM-A-1 saw brief operational service in the Korean War before being withdrawn from service in 1951.
The concrete enclosure also increases the surface area of the connection between the grounding conductor and the surrounding soil, which also helps to reduce the overall impedance of the connection. Ufer's original grounding scheme used copper encased in concrete. However, the high pH of concrete often causes the copper to chip and flake.
Icecap was scheduled for spring 1993. It had a planned yield of 20 to 150 kilotonnes of TNT (84 to 628 TJ) and was to be fired at 1,557 feet (475 m) below the surface in Area 9. [8] A diagnostics canister exists at the site, [9] weighing 500,000 pounds (230,000 kg). [10]
The German Stachelbombe (nose-spike bomb) or stabo of WWII was a standard bomb, from 50 kg to 500 kg, modified for use from low altitude. [5] To avoid the risk of ricochet from the ground, a nose spike was fitted to penetrate first and anchor the bomb against bouncing — without this, there was a risk of the dropping aircraft not only missing ...
The website lets you select your city, pick a type of bomb and the way of delivery, and hit detonate. The map will show the blast radius broken down into fireball, air blast and thermal radiation ...
The test area, also known as Area 13, was a 10 miles (16 km) by 16 miles (26 km) block of land abutting the northeast boundary of the Nevada National Security Site. [3] Project 57 was a combination safety test. The high explosives of a nuclear weapon were detonated asymmetrically to simulate an accidental detonation.
The main design consideration is that the bomb that the fuze is intended to actuate is stationary, and the target itself is moving in making contact. Naval mines Relevant design factors in naval mine fuzes are that the mine may be static or moving downward through the water, and the target is typically moving on or below the water surface ...
