Fuze Terminology and Types Flashcards
what are the 5 non explosive parts of a fuze
F-firing pin
R- rotor
E- escapement device
D- detent
S- slider
what are the fuze types classified as
point detonating
base detonating
point intiating-base detonated
what are the options on a point detonating fuze
super quick
delay
what are the two types of PIBD
mechanical- spit back
electrical- PE/lucky
what is a PTTF
powder train time fuze
what is a MT
mechanical time fuze
ET
electrical time fuze
how can you identify a PTTF
at least three rings, mostly made of brass
all have vent holes
what are the burn times for PTTF
if fixed time- 15 sec
if VT- 5 to 25 sec
how are MT fuzes armed
use centrifugal force and wound springs to motivate escapement devices
how can you identify a MT fuze
will not say “time fuze”
how can you identify a ET fuze
usually have a watch window, uses batteries
how can you identify a VT fuze
will have plastic-metal-ordnance
what are the three types of pressure
direct
fluid
air
how can you ID a point det (PD) fuze
looks very simple and cheap
might have SQ Delay settings
