WebSince the Stirling engine is a closed cycle, it contains a fixed mass of gas called the "working fluid", most commonly air, hydrogen or helium. In normal operation, the engine is sealed and no gas enters or leaves; no valves are required, unlike other types of piston engines. The Stirling engine, like most heat engines, cycles through four main ... WebCryocoolers are machines that keep sensors extremely cold so that satellites and space telescopes can take pictures on long-term missions. Whether we’re looking back toward Earth or outward into deep space, the sensors that capture images require extremely low temperatures. If sensors aren’t cooled to cryogenic temperatures, they simply won’t work. WebClosed Cycle Cryocooler Components.
