Research Institution
The innovation is a small, highly efficient, long life, low mass free-piston Stirling engine for low power applications. This machine is innovative because in addition to its small mass and physical dimensions it is anticipated to have 35 percent higher efficiency than engines now being considered by NASA. The proposed machine is expected to have 32 percent efficiency at a temperature ratio of 2.35 . Analysis work under the Phase I effort is intended to verify the projected efficiency, size, and the ability to manufacture such a unit. Fabrication, testing and development would be carried out under the Phase II effort.
