Been out of the forces for 25yrs. and I was never a mortar man and I was wondering what and what is the purpose of the devise at the end of the tube of the 81mm mortar ? Thanks
Like a mere gunner would know anything about this fine (stolen from the) infantry weapon.Mortar guy said:So what you're saying, Crafty, is that its called the Blast Attenuation Device (BAD) and was brought into service to reduce the blast over-pressures experienced by the mortar crews?
Hauptmann Scharlachrot said:Thread Rescued?
;D
Hauptmann Scharlachrot said:As to how it affects the transitional stage of ballistics (from internal to external), well, that will take page upon page of useless drivel.
Hauptmann Scharlachrot said:So, that "device" at the end of the mortar is one of two things:
(a) a baseplate (didn't say which end)
or
(b) Blast Attenuation Device (BAD), and its purpose is to attenuate the blast when fired ;D
little jim said:Others (arty) would expand on this in their teachings and ramble on with trivial points such as “it also helps direct the muzzle blast up and away” or “it is required during firing because the firing tables are based on this configuration.”
Michael O'Leary said:Now I'm curious where this came from, there was no reissue of firing tables when the BAD came into use (that I am aware of). Sounds like someone was tying to "over-technify" a lesson plan after taking it from the PBI.
