A concrete bomb is an aerial bomb containing dense, inert material (typically concrete) instead of explosive. The target is destroyed using the kinetic energy of the falling bomb, making it a kinetic energy weapon .
A kinetic projectile can also be dropped from aircraft. This is applied by replacing the explosives of a regular bomb with a non-explosive material (e.g. concrete), for a precision hit with less collateral damage; these are called concrete bombs. A typical bomb has a mass of 900 kg (2,000 lb) and a speed of impact of 800 km/h (500 mph).
Concrete bomb – contains dense, inert material (typically concrete) instead of explosives, using the kinetic energy of the falling bomb to destroy target Improvised explosive device – classification of bombs produced in unconventional ways or using unconventional materials; includes explosives such as the barrel bomb , nail bomb , pipe bomb ...
Overpressure in an enclosed space is determined using "Weibull's formula": [5] [6] = where: 22.5 is a constant based on experimentation = (kilograms) net explosive mass calculated using all explosive materials and their relative effectiveness
A Luftwaffe 1 kg incendiary bomb dated 1936 Royal Air Force "Grand Slam" earthquake bomb used towards the end of World War II. Aerial bombing saw widespread use during World War Two. A precursor was the 1937 bombing of Guernica by the Nazi German Luftwaffe and the Fascist Italian Aviazione Legionaria at the behest of Francisco Franco. [10]
Half-life (symbol t ½) is the time required for a quantity (of substance) to reduce to half of its initial value.The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive.
An antimatter weapon is a theoretically possible device using antimatter as a power source, a propellant, or an explosive for a weapon.Antimatter weapons are currently too costly and unreliable to be viable in warfare, as producing antimatter is enormously expensive (estimated at US$6 billion for every 100 nanograms), the quantities of antimatter generated are very small, and current ...
In physics, interference is the meeting of two correlated waves and either increasing or lowering the net amplitude, depending on whether it is constructive or destructive interference. If a crest of a wave meets a crest of another wave at the same point then the crests interfere constructively and the resultant crest wave amplitude is ...
