Overpressure (or blast overpressure) is the pressure caused by a shock wave over and above normal atmospheric pressure. The shock wave may be caused by sonic boom or by explosion , and the resulting overpressure receives particular attention when measuring the effects of nuclear weapons or thermobaric bombs .
The CBU-55 was a cluster bomb fuel–air explosive that was developed during the Vietnam War by the United States Air Force, and was used only infrequently in that conflict. . Unlike most incendiaries, which contained napalm or phosphorus, the 750-pound (340 kg) CBU-55 was fueled primarily by propa
Injury from blast overpressure is a pressure and time dependent function. By increasing the pressure or its duration, the severity of injury will also increase. [3] Extensive damage can also be inflicted upon the auditory system. The tympanic membrane (also known as the eardrum) may be perforated by the intensity of the pressure waves.
In simpler terms, a blast wave is an area of pressure expanding supersonically outward from an explosive core. It has a leading shock front of compressed gases. The blast wave is followed by a blast wind of negative gauge pressure, which sucks items back in towards the center. The blast wave is harmful especially to objects very close to the ...

The damper blades close automatically when pressure overcomes the resistance offered by the spring. Various models differ in the amount of blast protection (e.g. 1 bar/14.5 psi or lower amounts of protection) and whether they stay closed after the blast or remain functional.
The Hercules flew over the Thames estuary and headed south toward Brighton. After flying over the English Channel, Meyer turned northwest. North of Cherbourg he changed direction, heading south to a point 30 miles north of Alderney. [93] The Hercules crashed into the English Channel off Alderney (5000N, 0205W) [94] ~90 minutes later. In the ...
The need for a large bore made HEAT rounds relatively ineffective in existing small-caliber anti-tank guns of the era. Germany worked around this with the Stielgranate 41, introducing a round that was placed over the end on the outside of otherwise obsolete 37 millimetres (1.5 in) anti-tank guns to produce a medium-range low-velocity weapon.
