Overall performance of prototype piezoelectric SJ actuators will be reported along with plans for Phase II development and commercialization. Conformal coatings or encapsulation devices will also be developed to protect the synthetic jets from corrosive saltwater environments, operational temperature extremes, and damage due to abrasive dust. The variability of SJ peak performance will be measured with respect to operational conditions, and material and device characteristics. Fully functional piezoelectric synthetic jet prototypes will be assembled and tested in a laboratory environment in accordance with military and commercial specifications. In the proposed program, piezoelectric synthetic jets will be systematically developed, and under the prescribed environmental conditions, be tested for both military and commercial aircraft applications. Of particular interest is the use of piezoelectric SJ actuators as flight air flow control devices where their compact size, reduced weight and all-electric actuation make them desirable for use on high performance military aircraft. The abstract given for this project is as follows: Synthetic Jet (SJ) actuators have recently been pursued as solutions in active flow control applications, aeroshaping of airfoils, and even thermal management of microelectronics. Omega Piezo Technologies is a company that received a Department of Defense SBIR/STTR grant for a project entitled: F-35 Lift Augmentation with Synthetic Jets.
