48、 Note: The program-specific technical specification may include additional program-specific requirements that are not referenced in this document and may supersede any requirements included in this document. In the

49、 case of any conflicts between this document and the program-specific technical specification, the program-specific technical specification takes precedence.1.1 ScopeSee Program SSTS.1.2 Mission/ThemeThe Powertrain

50、Mounting Subsystem is designed to mount the powertrain to the vehicle structure. Mounting the powertrain to the vehicle structure consists of locating and supporting the powertrains mass, and managing the dynamic fo

51、rces of the powertrain (both internally powertrain generated and externally generated) with proper isolation. The Powertrain Mounting Subsystem is to carry out these functions while meeting the requirements of the v
