MZA is proposing to use both system and component level finite element modeling along with rapid prototyping enabled by additive manufacturing (AM) to iteratively design and test low SWaP optical mounts that passively isolate jitter. Each directed energy system has its own unique jitter challenges, and by developing a process to tune optical mount performance to its jitter environment, jitter can be reduced while minimizing overall system size, weight and power (SWaP). This approach is inspired by the extensive experience MZA has in jitter modeling, testing and beam control system design. Jitter models will be used to determine the expected input disturbance to the optic mount and also to identify key vibration modes of the mount itself. The design process will eliminate material in the mounts while retaining sufficient stiffness along the tilt axes of the mounted optic to not introduce additional jitter. We will utilize the ability of AM to introduce cavities and internal structure that cannot be made using traditional machining to accomplish this. These SWaP reductions will be combined with isolation approaches to further mitigate jitter. This process will be performed iteratively to arrive at optimized designs for both SWaP and jitter performance. Approved for Public Release | 20-MDA-10643 (3 Dec 20)

MZA is proposing to build on the Phase I work that leveraged both finite element modeling (FEM) and additive manufacturing (AM) to simultaneously reduce the size, weight and power (SWaP) and improve the jitter performance of optical mounts in directed energy (DE) systems. For Phase II, the design refinement strategy will be adapted to both mounts and structural assemblies in a quarter scale beam director and expanded to apply targeted damping to both mounts and the entire beam director. AM will be used to rapidly prototype and lab-test the designs to arrive at one that provides significant SWaP and jitter improvement. We will simultaneously advance our mechanical jitter modeling codes to facilitate design optimization of the targeted damping approach and enable application of the approach in future programs. The optimized designs will be flight tested on Notre Dame’s Airborne Aero-Optics Laboratory (AAOL) aircraft and the jitter improvement will be compared with baseline designs. Key results from the sub-scale testing will be applied to a full-scale system design that can be integrated with one or more of MZA’s existing beam directors. We will take this to the level of generic designs that can be directly marketed to other beam director manufacturers. Approved for Public Release | 22-MDA-11102 (22 Mar
