LM ESAF consists of what two types of modules?
Hellfire
.Electronics module
.2 x low voltage hardened time delay firing module
LVHTDFM
LM ESAF Electronic module contains? (6)
Hellfire
.Microcontroller
.field programmable gate array
.application specified integrated circuit
. g-switch inputs
.accelerometer inputs
. interfaces to communicate with missle controller and FMs.
LM ESAF LVHTDFM contains? (5)
Microcontroller .High Voltage storage capacitor .trigger Circuit .interfaces to communicate with the EM .uses a slapper detonator with EFI to initiate both Warheads
What does the LM ESAF do?
Hellfire
- Controls detonation initiation of the PC and MC Warheads
- EM provides logic to arms charge and fire the FM’s for both PC and MC Warheads
- Prevent unintended arming charging or initiation of both FM’s
- After all safety conditions are met the EMwill charge the FMs
