Titan IIIC Transtage/Stage II Separation-Shock Bench Test. Volume II.

摘要

Analytical studies were conducted to determine the feasibility of proposed concepts for shock attenuation. To support full and partial shock isolation of the guidance truss, vibration, loads and misalignment studies were completed that indicated that all related design constraints were met. Considerable analytical effort was required to size truss isolators, which led to isolator verification shock and vibration tests before the actual bench test series. Proposed shock attenuation concepts of truss structural modification, incorporation of shims at skirt attachment points, and torque variations on explosive bolts were found structurally feasible. Component isolation of the Missile Guidance Computer and Inertial Measurement Unit was found to be technically feasible except for thermal problems. This volume summarizes the analyses associated with the bench test program for the Titan IIIC Transtage Inertial Guidance System (IGS) truss. The volume includes total truss isolation, component isolation, IGS truss analysis, miscellaneous shock attenuation and dissipation analyses; results of supporting isolator vibration and shock tests; and separation nut studies.
