In this paper are reported some series of fundamental and developmental stage research works on the material properties and on the fabrication techniques. Results of burst test of 450 mm diameter test vessels and pressure test of 1,400 mm diameter test vessel are also shown., 資料番号: SA0125350000}, pages = {489--508}, title = {170キロ鋼によるロケット・モータ・ケースの試作}, volume = {6}, year = {1970} }
