Pulse width modulated servo valve enabled by single crystal piezoelectric

ABSTRACT: Surface-to-air missiles (SAM) represent a serious threat to both military and civilian aviation. However, development of more effective countermeasures requires realistic simulation of the missile plume to improve recognition capability. Accordingly, the purpose of this program is to design and build a next generation pyrophoric fluid valve (PFV) for the Towed Airborne Plume Simulator (TAPS) to improve its reliability and performance in plume simulation. This initiative will insert Active Signal Technologies high frequency actuation and valve technology into the TAPS to provide the required dynamic range and frequency capability to modulate the pyrophoric fluid flow. A development effort lasting approximately 24 months is envisaged to mature the technology and transition it to Arnold Engineering Development Complex (AEDC). A working prototype capable of delivering the necessary flow rates over the frequency band will be built and tested in the AEDC wind tunnel prior to construction and delivery of the final working device. Deployment of the new valve aboard the TAPS will enable the Air Force to conduct airborne tests of its Advanced Infrared Countermeasures (IRCM). This will enhance range capabilities at the Center for Countermeasures (CCM) at White Sands Missile Range (WSMR) with the goal of improving Aircraft Survivability.
