A -- A-SAVI MOVE SOL F29601-95-C-0064 POC Gail Hamblet, Contract Specialist, 505/846-4987/Joan F. Fulkerson, Contracting Officer, 505/846-5011. The Air Force Phillips Laboratory, Directorate of Contracting, Kirtland AFB, NM intends to award a sole source contract to Honeywell Satellite Systems Operation to provide engineering and technician support for the disassembly, reassembly, alignment and functional checkout the Space Active Vibration Isolation (SAVI) Device developed under Contract # F29601-85-C-0132. BACKGROUND: The SAVI Device is currently an integrated subsystem in the Space Integrated Controls Experiment (SPICE) test article.est article is being relocated from Building 765, Kirtland, AFB to the newly constructed SPICE Test Chamber located in Building 472, Kirtland AFB. This is a one time move to the new test facility, therefore no follow-on effort is contemplated by the government. Building 472 will be the final operating location of the SPICE test article. The SAVI Device subsystem is the only space qualifiable, six (6) degree of freedom (DOF) system isolator for a space based laser (SBL) currently in existence. The SAVI Device is a one-of-a-kind research and development hardware asset which defines the state of the art for advanced space based magnetic isolation systems. The SAVI Device consists of three forebody interface plates that are precision aligned and bolted to the upper stators of three pairs of magnetic actuators. The magnetic actuators consist of upper and lower stators enclosing a passive armature. The gaps between the magnetic aors and the armature are nominally 5 mm. The ability to center the armature in this 5 mm gap is critical to the performance of the SAVI Device. Improper alignment of the magnetic gaps will cause the stators to cock relative to the armature or bias toward the upper or lower hardstops of the magnetic actuator and degrade performance or potentially render the system unusable. The magnetic actuators are located at the vertices of a structure forming an equilateral triangle approximately 8 m on a side. This structure is known as the intermediate gimbal structure or IGS. The IGS itself consists of three (3) IGS Tubes and three (3) IGS Vertex Structures. These components are alsoligned and bolted together at precision machined interfaces to generate the equilateral triangle relationship and maintain high alignment tolerances necessary to insure the 5 mm magnetic actuator gap requirements. The lower stators of the magnetic actuators are precision aligned and bolted to the IGS Vertex Structures. Three (3) pairs of long stroke linear actuators are connected to the ''Y'' shaped aftbody simulator via support trunnions and to the IGS Vertex Structure via spherical bearings in clevis. The aftbody has a centrally located aftbody support system. The aftbody is also connected to the disturbance sources at the extends of the ''Ysturbance sources aelectro-magnetic shakers. The C-10 shakers are connected to the floor through reference base plates. The three (3) reference base plates and the aftbody support structure must be aligned relative to one another to ) 5 mm tolerances prior to their connection and grouting to the floor. The relationship between the reference base plates and the aftbody support structure define the first of several critical alignments that must be performed to insure the 5 mm magnetic actuator gap vertex are driven by a vertex electronics assembly (VEA). Each VEA conied 100 VDC control and amplifier The VEAs are powered by custom eleven cell battery stacks. The three (3) VEAs are slaved to the master electronics assembly which contains the primary controls processors for system command and control, data telemetry and external fire control commands. The SAVI Device isolator control system architecture consists of a series of control loops for both the magnetic and linear actuators. For the magnetic actuators, there are high bandwidth magnetic flux loops and low bandwidth forward position loops. For the linear actuators, there are high bandwidth tach rate loops to control flexibility and cross-coupling and low bandwidth follow-up loops. The systemability to generate feedforward retarget rate and acceleration directly to the high bandwidth inner loops and to provide retarget position command to forward position loops. As the SAVI Device is designed to perform in a micro-g environment, a gravity offload system must be used. The gravity offload system currently being used in Building 765 will not be relocated with the SPICE Test Article. A new three point floor standing pneumatic gravity offload system will be used. Due to this change in boundary conditions, the SAVI Device rigid body control laws must be modified. REQUIREMENTS: This contract will deal exclusively with the engineering and technician support necessary to disassemble critical SAVI Device interfaces and to reassemble and align the SAVI Device in Building 472 and perform functionality tests to demonstrate the required isolation (-80 dB) and retargetting capability (+ 2 degrees) goals. The Offeror shall be required to perform the following: (1) Develop a program plan to be approved by the government which shall: identify technical tasks, manpower requirements, and schedule, coordinate with the government move plans for the SPICE Test Article as it pertains to the SAVI Device, and evaluate the current status of the SAVI Device and identify items to be repaired/replaced. (2) Provide technical expertise for coordinating the disassembly of critical SAVI Device interfaces and subcomponents by the government and providing written handling and packaging instruction to the government. (3) Provide technical expertise to accomplish the precision locating of the SAVI Device reference base plates and lator support structure. Upon completion, the Offeror shall (4) coordinate the installation and reassembly the C-10 shaker disturbance system and aftbody simulator by the government in the SPICE Test Chamber located in Building 472. (5) Provide technical expertise for coordinating the re-integration of the SAVI Device linear actuators, IGS, and magnetic actuators. (6) Perform alignment of the SAVI Device once it is assembled and modify the control laws to accommodate the dynamics of the new gravity offload suspension system. (7) Perform a functional checkout to insure the SAVI Device is performing at the required isolation and retargetting goastablished by the SAOfferors must be able to demonstrate proficiency in performing all tasks. The Government will be responsible for the physical packing and relocation of the hardware from Building 765 to the SPICE Test Chamber in Building 472. It is expected that the Offeror may be required to procure hardware or materials iion. The offeror shall provide the government a list of required hardware and suggested procurement sources for hardware that must be replaced or repaired to insure functionality of the SAVI Device when installed in Building 472. The Government shall provide engineering and technic to assist in the tasks identified above. The offeror is required to maximize the available government manpower wherever possible to control overall cost. The Government will provide a new gravity offload mechanism and interface to the SPICE test article for transition into Building 472. This will require that the offeror have the ability to adjust the SAVI Device control system to accommodate changes in boundary conditions generated by the new gravity offload device.
