Abstract : This report documents work performed for the Aerospace Structures Information and Analysis Center (ASIAC) under ASIAC Task 35, "Analysis and Test support for Phillips Laboratory Precision Structures." Mr. James Goodding of CSA Engineering was the principal investigator for this task. Mr. Goodding is an integral team member on a number of experiments at the Air Force Research Laboratory (AFRL), Phillips Research Site. Task objectives centered around analysis and structural dynamic test support on experiments within the Space Vehicles Directorate at Kirtland Air Force Base. These efforts help to augment the Air Force's understanding of advanced technology devices and interactions with aerospace structures. One of the programs supported in this task was the Vibration Isolation and Suppression System (VISS), an AFRL experiment that will fly as part of the Space Technology Research Vehicle-2 (STRV-2) mission. VISS will demonstrate state-of- the-art vibration mitigation technologies for a satellite-based observation platform. Activities included environmental flight qualification test support and participation in the performance test program. The performance testing characterized both open and closed-loop dynamics used to implement the control laws. The Satellite Ultraquiet Isolation Technology Experiment (SUITE) is another AFRL experiment with many of the same objectives as VISS. Efforts in Task 35 included hardware and software development of the sophisticated active system experiment. Additional efforts included flight hardware acceptance test support for vibration and thermal/vacuum environments prior to delivery to Surrey Satellite Technology Limited (SSTL) for spacecraft integration. Assistance to the UltraLITE program was included in this effort. UltraLiTE will demonstrate the capability to control deployable space structures to nanometer accuracy in the laboratory.
