Tilt-Nose Control System Development for High-Speed Stratospheric Interceptors

Recent advances in the hypersonic system capabilities of adversary nations threaten the battlespace supremacy of US forces. Missile defense systems capable of extended high-g maneuvering at stratospheric altitudes and hypersonic Mach numbers will provide the MDA with additional flexibility in defending the US against emerging hypersonic threats. A key enabling technology for the deployment of such interceptors is a novel control system able to avoid the drag, aeroheating, and performance penalties associated with fin-based control at extreme Mach numbers. ATA Engineering’s research in Phase I examined four promising concepts employing conformal control mechanisms to achieve high-g maneuverability. The study indicated superior performance of a tilt-nose control (TNC) system to provide the high control effectiveness and excellent drag characteristics required for high-speed stratospheric intercept. ATA proposes a Phase II STTR project focused on technology maturation, risk reduction, and performance verification of the TNC system. Details of tilt-nose integration and design will be addressed and system integration risks will be studied and mitigated. The program will culminate in a hypersonic wind tunnel test at Mach 5, 8, and 14, resulting in a test-verified aerodynamics model to support continuing development and flight testing of the tilt-nose technology during Phase III activities.
