The US Armys modernization priority of long-range precision fires has identified a need for low-cost, high-g-survivable,fast-responding munition control actuation technologies. This research focuses on canard control actuation technologies forsubsonic flight regimes. Munition flight simulations were performed to obtain flight characteristics encountered by the controlactuators. Laboratory experiments were conducted to re-create the flight environment for the control actuation technology.Experimental results indicate that the transient response is not significantly degraded, to at least 3-Ncm canard hinge load(representative of Mach 0.6). However, the canard actuation assembly exhibits deformation that scales with the load. Thesestatic aeroelastic effects were quantified experimentally and assessed in Monte Carloguided flight simulations. Resultssuggest that static aeroelasticity does not affect delivery accuracy, which validates these specific technologies and the overalltechnical approach for achieving this mission.
