| Abstract: |
| The general mechanism and rules of blast characteristics of UDMH/N2O4 propellantexplosions are studied. Two essential concepts, TNT equivalent weight and terminal yield, are adopted. Three explosion modes are established. Blast characteristics of UDMH/N2O4 propellant explosionsare calculated with the theory we developed, and the parameters of distributing rules of blast characteristics of explosions are established. Compared with references abroad, reasonably good correlationis achieved. Blast characteristics of 10 kg, 50 kg, 100 kg and 300 kg UDMH/N2O4 propellant explosions are calculated and compared with the experiment data. |
