ABSTRACT

The world growth in research and development of High Operating Temperature IR detectors impels the development process and the optimization of rotary crycoolers at RICOR. The design aspects of size weight and power and the tradeoffs between them, were taken into consideration during the development process in order to optimize IDDCA for future hand held thermal sights.

This paper will present optimization tests results performed for rotary crycoolers at the temperature range of 110 – 200K FPA and also will review the development activities that will be implemented in order to minimize “Idle electronic and mechanical losses,” hence minimizing the regulated power consumption. As a result of the new approach to Rotary crycoolers for HOT detectors, the improvement in the reliability is analyzed and will be reported in the paper.

Keywords: Cryocooler, Rotary integral, Stirling, RICOR, HOT, SWaP, FPA.
