A Compact Cold Helium Circulation System with GM Cryocooler
WebMay 1, 1994 · This paper examines a vibration cancellation system that was designed for the expander of a Hughes tactical cooler. This system uses a custom-designed multi-axis counterbalance and an analogue implementation of an adaptive feedforward compensator. A non-linearity associated with the counterbalance is modelled, and its effect on the … WebThe incline shows that the adjusted cancellation signal constructively interferes with the cryocooler vibration levels at one of the nine displayed harmonic frequencies. The linear increase in phase, shown by the inclined line, is caused by incorrect phase alignment due to a non-optimal phase value within the adjusted cancellation signal. ... WebMar 7, 1999 · In the 1988 timeframe increasing numbers of proposed space-instrument programs within NASA and the Ballistic Missile Defense Organization (BMDO) were in need of high-reliability, long-life, low-vibration space cryocoolers.
