【Abstract】 A static simulation experiment for a non-tip-off rocket launch tube has been carried out,making use of the theory of local dynamic similiarity.Some experimental work on the secondary flow within the launch tube has been done,and characteristics of the secondary flow in the annular gap between the rocket body and the launch tube have been clearly elucidated.更多还原
