Blast deflector is one of the key infrastructures in the rocket launch site which deflects the high temperature and high pressure jet emitted by the rocket engine .Based on the computational flu-id dynamics theory , theoretical analysis , experimental investigations and numerical simulation were adopted to study the launch environment effects including the flow characteristic of jet engine flame in blast deflector and the disseminated property of jet engine noise .Issues concerning the flow safety and smoothness and the efficiency of spray system in design of blast deflector were evaluated .The performance assessment index of blast deflector was preliminarily set up by multiple analysis methods which may provide reference for the global performance optimization design of the blast deflector .
