| Abstract: |
| Toxic gas formed by the non burning propellant which splashes down to the ground and evaporates and diffuses after the liquid propellant carrier rocket explods is harmful to missionary and ambience.The analytic model of the toxic gas,which is formed by residual propellant vapouring after liquid propellant rocket exploding and is diffusing in the atmosphere is presented.The distribution of the consistency field of ground gas in different environment and weather,and the process of toxic gas diffusion,are numerically simulated |
| Key words: Liquid propellant rocket engine Launching site Explosion accident Propellant toxicity Gaseous diffusion Numerical simulation |
