The "rope tricks" that protrude from the bottom of the fireball are caused by the heating, rapid vaporization and then expansion of guy wires that extend from the shot cab—the housing at the top of the bomb tower that contains the explosive device—to the ground.
ZUS-40s were designed to fit underneath most Luftwaffe bomb fuzes. When a delayed-action bomb containing a ZUS-40 was dropped on a target, the impact when it hit the ground freed a ball-bearing inside the ZUS-40, thereby arming a spring-loaded firing pin. As long as the main bomb fuze remained inside its fuze well, the cocked firing pin in the ...
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 ...
When the Mk 20 bomb cluster is released from the aircraft, the arming wires (primary and/or optional arming) are pulled sufficiently to arm the Mk 339 fuze (and recently the FMU-140 fuze) and release the fins. The positive armed fin release arming wire frees the fin release band, and the movable fins snap open by spring-force.
Note: some fuzes, e.g. those used in air-dropped bombs and landmines may contain anti-handling devices specifically designed to kill bomb disposal personnel. The technology to incorporate booby-trap mechanisms in fuzes has existed since at least 1940 e.g. the German ZUS40 anti-removal bomb fuze. [26]
Of the scene which has been left after the removal, Mrs James added: “It looks horrendous with all the work they had to do to get rid of the bomb. “They knocked down a wall and the garden is ...
On Friday at 5.32pm after the 500kg unexploded bomb had been moved in a military convoy to the sea where it is to be disposed of , Plymouth City Council lifted a 300-metre cordon of evacuated ...
The first bomb in the stick was fitted with an impact fuze while the other bombs were fitted with pressure sensitive diaphragm actuated detonators. The blast from the first bomb was used to trigger the fuze of the second bomb which would explode above ground and in this turn would detonate the third bomb with the process repeated all the way ...
