The Army is interested in improving precision guided munitions for achieving longer ranges with higher accuracy, thus reducing both collateral damage and achieving cost savings. Canard flight control surfaces are an effective technology to improve the overall performance and effectiveness of munitions systems. However, embedded canard actuation systems (CAS) are one of the most costly components in spinning projectiles. New actuation mechanisms that are both scalable across multiple caliber systems, and applicable to new projectile designs are required. The design of CAS requires an integrated multidisciplinary approach coupling aerodynamics, structures, dynamics and controls. To address this need, IAI and collaborators at Raytheon and the University of Maryland will develop CASMO, a CAS design tool that leverages multidisciplinary optimization using a careful balance of multi-fidelity analysis. CASMO will enable an in-depth physical understanding of CAS designs, as well provide an ability to design systems that are easily scalable, lightweight and inexpensive. The proof-of-concept for CASMO has already been developed. After further refinement, the concept will be demonstrated through further hardware prototyping and testing. CASMO can help the Army design scalable, reconfigurable actuation systems that can be fit across several legacy and novel projectiles. It will also enable multi-point, multi-objective optimizations, and provide an in-depth understanding of the underlying physics. Technical innovations developed during this work can be extended to developing control surface actuation systems for any small flight platform in the military and civilian sectors. CASMO will be directly relevant to several programs at DOD, and will be of interest to defense contractors, and for applications in fields like aircraft and automobile design.
