Bombs Flashcards
Main bomb components
case or body tail unit suspension lugs main filling fusing system
tail unit variations are
angled fins units and fins that spring into place permanently attached arming vanes drag plates or fins ballute and parachute
what are the 2 general 2 categories of tail unit
retarded
non retarded
other bomb attachments are
Kopfring Anti-ricochet ring stabo dinort rods arming wire
5 bomb categories
High Explosive Chemical agent Incendiary FAE Practice

methods of arming
mechanical
electrical
electro-mechanical
combination
fuse positions
nose
tail
transverse
Describe WW2 British bombs
cone or drum tails, single suspension lug. later bombs had choice of single or double fuze (nose tail or both) arming vane/arming fork may be present
Describe WW2 American bombs
open, square, box shape tail units, thin construction secured with a large nut. tails corrode easily laving the nut. double suspension lugs and nose or tail fusing
Describe WW2 German bombs
cruciform parallel fins, cut of at a 45 degree angle. bolted on or part of the construction. may have a cross brace. single screw suspension lug at nose or center of bomb. all fusing was transverse with single or double fuse pockets
Describe WW2 Soviet bombs
Tail units can resemble British American or German tails. may have multiple fins. can be bolt on, or welded on.
Before RSP on pistil or fuse determine

Plan of attack
3 criteria that aid in recognition of fuses
position in store
method of arming
functioning action
8 functions of arming
impact/short delay airburst influence hydrostatic long delay anti disturbance protective/anti handling modular/smart
3 types of action
direct
indirect
combination
5 types of direct action
shear wire compression spring diaphragm/membrane heat compression electrical
4 types of indirect action
compression spring
plate
cocked striker
heat compression
Air burst pistils and fuses include
mech time mechanical electrical pyro time barometric blast pressure prox
Stimuli used in influence fusing
Radio - activve Radio -passive light heat Acoustic/seismic magnnetic IR/laser
Influence fusing ID features
larger than other types of fusing
normally contain aerial or sensor arrays
may have a plastic or ceramic radome
Hydrostatic fuses are armed by
vane rotation prior to entering the water
pressure on internal bellows
a combination on both
4 types of long delay fuses and pistils
chemical
material creep
clockwork
electrical
Chemical ID features
weakened portion of pistil/fuze, designed to break off
stub of arming fork may be visible
smell of acetone
chemical corrosion
5 types of anti withdrawal fuses
clawed foot offset groove and ball knife edge anti removal sleeve electrical contact
