OUTER WALL STRUCTURE OF ROCKET STRUCTURE BODY

PURPOSE:To provide the outer wall structure of a rocket structure body which prevents the internal heating free from the combustion of the outer wall by the air frictional heat generated during the flight of a rocket and does not generate the gas which gives bad influence in the ultrared ray observation. CONSTITUTION:The outer wall member 12 of a rocket structure body is constituted of the inner and outer layers consisting of the inner cylinder 13 and an outer cylinder 14, and a space part 15 is formed between the inner and outer cylinders 13 and 14. Further, the outer cylinder 14 is made of the light material such as titanium having the high strength at high temperature and high thermal expansion coefficient.
