Fuze and Pistil Flashcards
Difference between a fuze and a pistil
a pistil contains no explosive content
General Terms
Armed Armed and Functioning Arming Arming Delay Boresafe Detonator Safe Direct Arming Firing Fuze Graze Sensitive Partially Armed Pistol Unarmed/Safe
What is Acceleration/Setback
rearward movement of fuze parts caused by forward acceleration during firing
What is Deceleration/Creep?
Forward motion of fuze components relative to the fuze body, caused by deceleration
What is Inertia
continuing motion of fuze components upon sudden deceleration of fuze. Inertia and deceleration differ by the speed at which the fuze/ordnance slows
What is Centrifugal force/spin
outward movement of the fuze components from the center of the spin
what is mechanical
physical movement of fuze components
Arming Vanes
turned by air or water past the ordnance
3 ways arming vanes work
mechanical alignment of parts
provides electrical power through a generator
a combination of both
Types of firing forces and principles
Impact Impact Inertia Magnetic Acoustic Seismic Material Creep/fatigue Chemical action/delay Proximity PTTF
2 types of magnetic firing
Magnetic Induction Generator (MIG)
Penetration Induction Generator (PIG)
2 types of acoustic firing
Acoustic Intensity
Acoustic Signature
2 types of Prox
Active
Passive
Dual Purpose applies to both arming and firing. what forces/principles does it use
Pressure
Electrical
Mech Time/Clockwork
Springs
Examples of pressure forces are
Gas pressure Direct pressure Hydrostatic pressure fluid pressure air pressure
