Title: Single Crystal Piezomotor for Large Stroke, High Precision and Cryogenic Actuations
Agency: NASA
Contract: NNC04CA87C
Award Amount: $70,000.00
 

Abstract:

TRS Technologies proposes a novel single crystal piezomotor for large stroke, high precision, and cryogenic actuations with capability of position set-hold with power-off. The proposed concept will advance the state-of-art cryogenic actuations considering the excellent cryogenic properties (with d33 and d31 at 30K similar or higher than that of PZT at room temperature) and the great electromechanical coupling of single crystal piezoelectrics, and the novel design of the ?wobbling mode? piezomotor with ?33 mode? single ring stacks instead of the conventional ?31? mode plates for excitation. In the Phase I project, the cryogenic properties of single crystal piezoelectrics with various crystal cut will be investigated. FEA modeling that takes into consideration the special properties of single crystals and a cryogenic environment will be conducted and a novel piezomotor with ?33? mode single crystal ring stacks and screw driven structures will be built and characterized at temperatures from 300 to 20K. At the conclusion of Phase I program the feasibility of ?wobbling mode? piezomotor for large stroke cryogenic actuation will be demonstrated. Optimization of the single crystal piezomotor design and the development of a large aperture cryogenic mirror or reflector will take place in Phase II.
