22. Advanced Aluminum Alloys for Launch Vehicle Pipeline Parts Manufacture

Authors:

Bondarenko О. V.², Mogilevtsev O. А.¹, Tishchenko Y. S.¹

Organization:

Yangel Yuzhnoye State Design Office, Dnipro, Ukraine¹; Oles Honchar Dnipro National University, Dnipro, Ukraine².

Page: Kosm. teh. Raket. vooruž. 2017 (2); 127-130

Language: Russian

Annotation: The comparison has been made of mechanical characteristics based on yield strength values of prospective aluminum alloys and steels with the stresses arising in pipeline parts. The conclusions have been drawn about the principal feasibility of manufacturing the pipelines of given materials and replacing the steels with the high-strength aluminum alloys for majority of the parts.
