Stirling Engine: Principle of Operation and Where to Buy It?

The Stirling rotary engine belongs to external combustion engines. Their peculiarity is that they need an external source to start the processes. Whereas in internal combustion engines, fuel burns inside, ensuring the operation of the engine. Stirling engine devices are presented in the Fama online store by various models from the German brand Böhm. It is named after its creator, Hermann Böhm, who began producing these wonderful devices in the 90s.

But earlier, the German learned to work with steel casting, improving his understanding of engineering processes and sense of form. After graduating, Böhm, having saved up enough money, opened his own business producing various fasteners and parts for industrial tasks. But all this was only preparation for his vocation, when Hermann was thinking about a Christmas gift for his clients and saw a Stirling engine in a model magazine. He decided to assemble such a motor himself, and then everything started to spin.

Stirling engine: what it is and the principle of its operation

The principle of operation of the Stirling engine is as follows. The mechanism works thanks to heat, which causes the gas inside to expand and push the piston, which in turn starts the operation of the device to which the engine is connected. At least, this is how the models from Böhm come to life. The engine itself is named after its creator, the Scottish priest Robert Stirling. He wanted to reduce the level of injuries among people who worked on steam-powered machines, which from time to time exploded due to pressure.

Stirling achieved what he wanted, his engines were much safer, but both they and the steam engines were supplanted by their more advanced counterparts. But the advantages of the Stirling engine breathed new life into this technology. It is currently used in the space industry, for example, the Titan Saturn System Mission, a project that is to fly to Saturn and its moons, is equipped with these engines. And the submarines of the Swedish Navy operate almost entirely on Stirling engines due to the fact that their shortcomings (size and the need for cooling) are largely eliminated in water.

Types of Stirling engines

Stirling engines with a generator can be divided into two types. The first - these are the motors themselves, which are usually attached to some mechanism. For example, it can be a model of an oil derrick or a windmill. And the second - various kinds of cars and locomotives. They are made in a steampunk or vintage style, which was characteristic of the era when Stirling engines were widespread. By starting the engine, for example, from a burner, all models come to life. The cars start to move, and, for example, a Ferris wheel - spin.

Where to buy a Stirling engine?

Original models of the German brand Böhm, operating on a Stirling engine, can be purchased in the Fama online store. It is with us that you can be sure of protection against fakes. Despite the fact that in fact these models are toys, the complexity and thoughtfulness of the design and technical execution make them an ideal gift. Especially when you start the device in front of the birthday person with a magician's gesture, and it comes to life.

The Stirling engine is a unique thing in a sense. Created in the era of steam engines and the telegraph, it managed to find a second life when it is used in the technologies of the future. In addition to the already mentioned spacecraft and submarines, such motors are also planned to be introduced into the operation of solar generators. And the Stirling engine is an opportunity to safely and without the need for refueling use models of anything: from a marble processing machine to a Scandinavian longship. And for you - a chance to give something original and unforgettable.
