High Velocity Gun-Launched Projectile and Sabot Structures

The U.S. military is increasingly focused on long-range warfare by delivering time-critical guided hypersonic projectiles to troops on the ground. Additionally, in recent years long range precision fires have become a priority for ranges on the order of 250 nm. On the development path to reaching these extended ranges, the U.S. DoD, Strategic Capabilities Office, Office of Navy Research, Navy and Army have developed launch packages designed to reach, and are closing in on, 80-100 nm ranges. To exceed these ranges with current projectile masses, supersonic and eventually hypersonic launch velocities need to be attained. These velocities require continuous material and structural improvement to reduce parasitic mass as well as advanced aerodynamic designs to increase flight range and manage concomitant thermal loads. Control surface technology must be state-of-the-art. Simulation, LLC shall enhance their state-of-the-art composite sabots and implement new features and new shifts in sabot paradigms, create novel aerodynamically designed aeroshells, and implement aerothermally stable control surfaces Simulations, LLC has been engineering and manufacturing composite sabots and ILPs for the Navy Hypervelocity Projectile (HVP) and EMRG programs, and Army medium caliber guns for over ten years, and shall transition their knowledge to this SBIR effort.
