Abstract

Non-toxic, pollution-free loading system of lox is used in new launch vehicles. In the progress of loading or venting lox, the accident detachment of fuel connector will lead to leakage and diffusion of lox. Low temperature and oxygen enrichment caused by lox leakage will bring great damage to workers and equipment. Numerical model of oxygen leakage and diffusion is established and calculated. The spatial range and duration of the hazardous area are analyzed according the simulation. The result shows that the spatial range and duration of hazardous area increase with the raise of pipeline pressure. Operators of aerospace launch site should keep away from the hazardous area during the specific time slot, and handle the accident effectively on the basis of adequate protection.
