The primary objective of the piezoelectric pump program is the development of enabling pump technology for space applications. Pumps under development are characterized by reduced mechanical complexity, increased reliability, improved efficiency, reduced volume, and reduced weight, with respect to conventional pumps. With a combination of sponsor and internal funding, two generations of pump designs were built and tested. The main products were design understanding and sizing equations, and a marked improvement in pump performance as the design evolved. The basic engineering developed on this project has broad aerospace applications.
