Vuilleumier Cycle Cryogenic Refrigeration System for Missile Guidance Applications.
Abstract
The report describes the development of a Vuilleumier (VM) cryogenic refrigeration system for the infrared seeker of a medium sized missile of the AIM-9E class. The refrigeration was designed for installation within the nose cone section of the missile; such an installation required an 'in-line' design. To make it operable in the high-temperature environment of the missile, the cold end of the refrigerator was designed with two stages. A molten metal heat sink absorbs the heat when the missile is traveling at high velocities and the heat sink is inoperative. The refrigerator contains controls for constant power to the motor and temperatures of the cold and hot cylinders. The refrigerator was given thermal, vibration, and shock tests. In addition, there were background noise tests. This report also presents the advantages and disadvantages of using two-stage VM cryogenic refrigerators in airborne systems.
