The foreword outlines NASA’s high-pressure oxygen-hydrogen rocket technology program and the need for improved aerothermodynamic load understanding, structural dynamics, and fatigue and fracture life modeling. The publication compiles extended abstracts covering aerothermodynamic loads, probabilistic structural dynamics, and fatigue and constitutive modeling efforts across multiple sessions.","STAR17JUL 1985  \nStructural Integrityand Durability ofReusable SpacePropulsion Systems  \n(NASa-CP-2301)  S7FJCT!EL INTEG ITY ANDNE5-27541DUkABILIIY ur EELSAbiF =PAL三EFC25LSICHEISYSTLs (SASa)  151 p h(AC9/8 A01 CSCL 21HN85-2797iUnclasG3/20  20337  \nProceedings of a conferencehald at NASA Lewis Reseerch CenterCleveland,OhioJune 4-5,1985  \nN/SA  \nStructural Integrityand Durability ofReusable SpacePropulsion Systems  \nProceedngs of a conferencesponsored by the NASA Office of Aeronautics andSpace Technology and Office of Space Flightand the NASA Lewis Research Centerand held at NASA Lewis Research CenterCleveland,OhioJune 4-5,1985  \nFOREWORD  \nThe space shuttle main engine,a reus able space propulsion system,is themost sophisticated rocket engine in use today.However,on the premise thatthe United States will depend on the shuttle and its derivatives as its prin-cipal Earth-to-orbit transportation system for the next several decades,theNational Aeronauti:s and Space Administration(NASA)has decided to continuallyupgrade SSHE capabilities.Therefore,NASA has initiated a research and tech-nology program for advanced high-pressure oxygen-hydrogen rocket technology.This program is intendd to establish the basic discipline technology and todevelop new analyticai tools for ar orderly evolution of reusable rocketsystenas.  \nA substantial porcion of this technology program is devoted to the struc-tural integrity and durability aspects of reusable space propulsion systems.This effort will improve the understanding of aerothermodynamic loads,struc-tural dynamics,and fatigue,fracture,and life issues in the SSME and itsderivative engines.The overall approach is to examine and modify existinganalytical methods,to develop new methods where needed,and to verify them insystematic test programs.The research is conducted through industrial con-tracts,university grants,and in-house activities at the Lewis ResearchCenter.  \nTo provide a forum for representetives from governszent,industry,andacademia to learn about and discuss the latest findings and progress towardimproved structural integrity and durability of reusable space propulsion sys-tems,a two-day conference was held at Lewis in June 1985.This publicationcontains extended abstracts of the papers presented at that conference.  \nStanley J.MarsikConference Chairman  \nCONTENTS  \nOAST TECHNOLOGY PROGRAM- DURABILITY EFFORT  \nF.W.
