Backflash or Backfire Breechflash or Flare

The flash produced at the breech of a gun when the breech is opened after firing a round. This is caused by the ignition (and expln) of CO and hydrogen of combustion gases at the moment of their contact with oxygen of the air. If the temp of the gases is not sufficiently high to produce self-ignition, the back-flash may be caused by a piece of smoldering or burning resi due of proplnt or bag left in the gun barrel after firing. The presence of CO and hydrogen is explained by the...

Blanketing Compositions for Blasting Explo sives See under Sheathed Explosives

Blank Powder is used in firing signals, for saluting, for manoeuvres and, in fact, in all cases where it is required to make noise of firing without ejecting a projectile. Instead of projectiles felt wads are used. As the wads do not offer resistance to the expansion of pdr gases, the pressure in the weapon decreases after firing almost to zero. In order to offer greater resistance to the pdr gases the cartridge is sometimes provided with a mock shot made of hollow wood or other suitable...

Big Bertha Paris Gun and Other German Big Guns

Many big guns were developed in Germany some of them with a max range of ca 120km. Following is an incomplete list of such guns a) Paris Gun(Parisgeschutz) or Long Range Gun (Ferngesch tz) was a 21cm(ca 8 ) weapon with the length of the tube 34m. Its max range was 120km. As the life of these guns was only 50-60 rounds, they were rebored to 240mm and later to 260mm (Ref 1). According to Ley(Ref 3), the guns 21cm L 150 and 23.5cm L 132 were known as Paris Guns.
