Product information "Stirling engine The big Laura"
The Stirling engine "The Great Laura" is similar in design to a horizontal plank hot air engine from 1910. Like every Stirling engine, this horizontal, air-cooled heat engine has two cylinders with pistons, the displacement cylinder and the working cylinder. The working cylinder is made of steel, the displacement cylinder is made of aluminum with a 60mm diameter due to better thermal conductivity. In addition, the displacement cylinder is equipped with cooling fins to ensure the machine runs for as long as possible. Like its historical model, the hot air engine has a flywheel and a pulley.
All materials, screws and accessories required to build the Stirling engine "The Great Laura" are included in the kit. All milled parts are prepared to such an extent that they only need to be deburred and possibly drilled.
The model
The Stirling engine As you can tell from the name, “The Big Laura” is a large version of our very successful “Laura” Stirling engine kit. The size of this model brings with it some advantages. Due to its large surface area, the Stirling engine can dissipate heat better and therefore run longer. The tank of the Stirling engine "The Big Laura" is extra large. A tank full of denatured alcohol lasts 8-10 hours depending on the size of the flame. In addition, significantly lower speeds are possible with this large Stirling engine than with small model Stirling engines. But even high speeds are no problem for the model. The speed of this hot air motor can be controlled using an adjusting wheel. The burner is firmly connected to the model and the base plate. A 140mm flywheel and a pulley in our well-known cast steel quality run on the drive shaft. The working cylinder consists of a hydraulic cylinder tube and no longer needs to be processed on the inside. The included oak base plate is also pre-milled.
The blueprint and construction instructions included with the Stirling engine are very extensive, detailed and easy to understand. For the model maker who has always wanted to build a large Stirling engine himself, the Stirling engine "The Big Laura" is a well-suited model.

To build the Stirling you will need a medium-sized lathe, a column drill and a gas burner for brazing and soft soldering. There are also hand tools that should be in every "model making machine shop" (tap M2, M3, M4, M8x0.75, M10x1 die M3, M8x0.75, M10x1 reamer 3H7, 4H7, 5H7, 8H7, 10H7) files and a drill set is necessary.
You can find a detailed construction report for this model in our Bengs model building magazine. In the Construction report of the Stirling engine “The Great Laura” you will find lots of pictures and explanatory texts. This means you can find out in advance about the work that needs to be done. But the Stirling engine construction report can also help you during construction.
