An Active Thrust Vectoring (ATV) Control System for Tactical Missile Steering

Next generation rocket propulsion systems are shifting towards higher levels of performance by incorporating advanced thrust vectoring capabilities for increased missile turning rates and maneuverability. For the Phase II program, Orbital Research will collaborate with The University of Toledo, Innovative Technology Applications Company and the Propulsion Research Center (PRC) at The University of Alabama in Huntsville to develop an Active Thrust Vectoring (ATV) system for tactical missiles using optimal nozzle designs with integrated flow control and Microelectromechnical Systems (MEMS) technologies. The program will focus on the application of low-power, light-weight, mechanical control actuators to achieve thrust vector control with limited thrust losses. Phase I results successfully demonstrated the feasibility of the passive miniature actuators on multiple ‘planar’ 2D nozzles using two thrust vectoring concepts: Sonic Plane Control (SPC) and Shock Vector Control (SVC). Phase II will focus on the development of an optimal Active Thrust Vectoring control system for 3D nozzles to fit inside the 7” diameter missile hardware to ensure compatibility with the current air-to-air missiles. The program will use 3D Navier-Stokes simulations, and cold-flow and hot-firing jet experiments to design, assess and demonstrate the ATV technology for tactical missile steering.
