29- Blast Warheads and Damage Prediction Flashcards
Diffraction Loading
Caused by Peak Overpressure
Applies pressure from all sides
Very short, but ver powerful; Crushes target
Definition of Energy Coupling
Destructive energy transfer from warhead to target
1. Propagation: pattern/shape that energy is ejected
2. Attenuation: warhead destructive potential falls off with distance
3. Damage Volume: defines weapons destructive effectiveness
Drag Loading
Caused by the Dynamic Pressure acting on the surfaces normal to the shock front
Push/Pull on target
Blast pressure to kill a human?
4.5 times atmospheric pressure
What is Mach Stem / Wave?
A shock wave that is a combination of an incident and reflection wave
- Psyn and Ppk almost double
- “Mach stem” - vertical wave front
What is the Triple Point?
Interaction of original wave, reflected wave, and newly created “mach wave”
How is Blast Damage inflicted?
Based on:
- Damage Mechanism
- Blast Pressure
- Target Type
What is Ground Distance (dw)?
Provides the range where a certain damage effect will be felt by a target
dw defines Area of Effect
higher dw = lower Aim Point Accuracy
