An analysis of the thermal oscillations observed during the two-stage Miniature Pulse Tube Flight Cryocooler (MPTFC) experiment on STS-108 (Dec. 2001) is presented. Orbit-induced thermal oscillations at the heat rejection surface produce sympathetic oscillations in the cryocooler warm components, which in turn propagate to the cold stages during cooler operation. The warm component analytical model discussed here was derived by solving a system of coupled differential equations that include heat flows from the experiment, the periodic solar incident radiation, and the IR heat rejection. In order to model the cold stage thermal behavior it is first necessary to ascertain the thermal behavior at both the heat rejection surface (EMP) and the aftercooler, which directly drives those oscillations. Unfortunately, there was relatively poor temperature resolution by sensors on those two components, but very high resolution on other warm end components. The model therefore seeks to determine unambiguously the EMP and aftercooler periodic thermal behavior. Results are compared graphically to the on-orbit temperature measurements.
