GR-5 Experimental Turboshaft Engine

       These pages chronicle the construction of a home-built turboshaft engine. The GR-5 is an experimental gas turbine engine that I have built so I can learn firsthand about gas turbine engines. I am posting this information for other enthusiasts to possibly benefit from. If you have any questions or comments about this project feel free to contact me.

Thanks, Don Giandomenico

       WARNING ! This project is posted for entertainment value only! Do not attempt to re-create this project as these articles are not written as “how-to” or “instructable” articles. There are no plans or engineered drawings on these pages so please do not attempt to build an engine solely from the information posted on this site!!!

 6/6/04 Designing and building the GR-5 turbine housing

 6/23/04 Installing the bearing heat shield and stator

 6/26/04 Assembly of the GR-5’s power transmission

 6/28/04 Building the power turbine wheel

6/30/04 Final assembly of the gearbox & frame

       I had taken photos of the project as I was progressing through the construction of the GR-5. I have put these Construction Photos together in an album for easy viewing. The photos may be helpful to those researching the gas turbine engine.

       See a video of the       GR-5 Turboshaft Engine run! Seeing is believing so check this one out!
