Improved Thermal Management for Miniature Pyrophoric Flow Control Valves and Actuators

Surface-to-air missiles represent a serious threat to both military and civilian aviation. However, development of more effective countermeasures requires realistic simulation of the missile plume over a wide range of observation distances to improve recognition capability. The Air Force Towed Airborne Plume Simulator (TAPS) provides the simulation capability but its operation is limited by the size and performance of available actuators. Accordingly, the purpose of this program is to design and build miniaturized actuators for the TAPS to improve its reliability and performance. Active Signal Technologies (AST) will insert its novel high-frequency actuation technology into the TAPS to provide the required dynamic range for more efficient and advanced testing. A development effort lasting approximately 24 months is envisaged to mature the company's technology and transition it to Arnold Engineering Development Complex (AEDC). AST will build prototypes capable of delivering the necessary dynamic range and frequency response. AEDC will test the final actuators in its wind tunnel. Deployment of these actuators aboard the TAPS will enable the Air Force to conduct airborne tests of its Advanced Infrared Countermeasures. This will enhance range capabilities at the Center for Countermeasures at White Sands Missile Range with the goal of improving aircraft survivability.
