hot air
https://www.youtube.com/watch?v=q2I8VNAmnLY  How to build a steel turbine using only a drill press and basic tools such as a hacksaw and files! This video will demonstrate how to make a reasonably well-balanced and functional turbine on a tight budget, suitable for a wide variety of different projects, including energy generation, jet engines, etc. This video is part of a larger series on my Turbojet engine project I'm working on, subscribe for more updates on this! files at https://mega.nz/folder/w3YlQJjJ#lSCbQoXOiPf-ZJIGWbYJbQ https://www.schmid-energy.ch/en/hot-air-turbine

3dprinted
https://www.youtube.com/watch?v=Yg5swK_AnbU In this video I'll experiment with some designs for a 3d printed compressed air turbine. I started this project because I wanted to research better designs for steam turbines without spending the time and money required to CNC the parts out of metal, and i got results that were almost good enough to be usable for a light duty shop tool. The highest power i measured with a simple 2D turbine on 50 PSI was 16.4 watts. I did all my power measurements with a magnetic dyno. I also built an aftercooler to remove some moisture out of the air, because I eventually want to use a compressed air turbine for the expansion phase of a brayton refrigeration cycle for cryogenic cooling (if i can get the turbine efficient enough). Both turbine designs i tried in the video use a 1/16" diameter nozzle insert that's CNC'ed out of aluminum. The results at the end of the video are both shown at 50 PSI.

Ship models no longer have to do without the advantages of turbine technology. The JetCat SPM5 twin-shaft engine has high power reserves in high-tech guise. The basic design and functionality largely correspond to the engines used in the man-bearing area. The principle is easy to understand. It is necessary to convert the high power of the engine into usable shaft power in a suitable way. However, this is not easily possible at the very high speeds. The necessary reduction is therefore carried out in 2 stages. First in a gas transmission, then through a gear transmission. This means that the gas jet of the so-called core engine drives a turbine wheel in operation, which sits on a second shaft. This second shaft is mechanically absolutely independent of the rotor of the basic engine and receives its drive power only from the kinetic energy of the exhaust gas jet. The second shaft drives directly into a gear suitable for high speeds, which reduces the speed to suitable output speeds. A water cooling system integrated in the gear ensures the necessary cooling of the components subjected to higher temperatures. Also completely new is the electronic control which processes and regulates both the speed of the primary and secondary shaft. The pilot can fully concentrate on driving, the complex engine management is fully electronic. The electronics on the turbine side are encapsulated in a waterproof encapsulation and equipped with waterproof connectors.

The JetCat SPT turboprop engines have high power reserves in high-tech guise. The basic design and function of the engines are similar to those used in man-bearing aviation. The principle is easy to understand. It is only necessary to convert the high power of the engine into usable shaft power in a suitable way. However, this is not easily possible at the very high speeds. The necessary reduction takes place in 2 stages. Once in a gas ratio, then through a gear transmission. This means that the gas jet of the so-called core engine drives a turbine wheel in operation, which sits on a second shaft. This second shaft is mechanically absolutely independent of the rotor of the basic engine and receives its drive power only from the kinetic energy of the exhaust gas jet. The second shaft drives directly into a gear suitable for high speeds, which reduces the speed to suitable propeller speeds. Also completely new is the electronic control which processes and regulates both the speed of the primary and secondary shaft. The pilot can fully concentrate on flying, the complex engine management is fully electronic.
