|
The amount of time or vane
revolutions needed for the firing train to be aligned after the bomb is released or from time of release until the bomb is fully armed. It is also known as safe separation time (SST). |
Arming time.
|
|
|
When the functioning time of a fuze is
longer than 0.0005 second. |
Delay.
|
|
|
A means by
which a fuze is physically determined to be in a safe or armed condition. |
External evidence of arming (EEA).
|
|
|
The time required for a fuze to
detonate after impact or a preset time. |
Functioning time.
|
|
|
When the functioning time of a
fuze is 0.0003 second or less. |
Instantaneous.
|
|
|
When the functioning time of a fuze is
0.0003 to 0.0005 second. |
Nondelay.
|
|
|
The action that causes a fuze to
detonate before impact when any substantial object is detected at a predetermined distance from the fuze. |
Proximity (VT).
|
|
|
The distance along the
trajectory that a bomb travels from the releasing aircraft in an unarmed condition. |
Safe air travel (SAT).
|
|
|
Fuzes are normally divided into two general
classes |
mechanical and electrical
|
|
|
It must remain safe until the bomb is released
and is well clear of the |
delivery aircraft (arming
delay or safe separation period). |
|
|
if the bomb is
accidentally released or if the bomb is jettisoned in a safe condition from the aircraft.It should not |
detonate the bomb
|
|
|
Some fuzes incorporate special safety features. The
most important safety features are |
detonator safe, shear
safe, and delay arming. |
|
|
do not have the elements of
their firing train in the proper position for firing until the fuze is fully armed. |
Detonator safe fuzes
|
|
|
The elements remain firmly
fixed and out of alignment in the fuze body while the fuze is unarmed. |
Detonator safe fuzes
|
|
|
does not become armed if its
arming mechanism is damaged or completely severed from the fuze body. |
A shear-safe fuze
