GR-7 Experimental Turbojet Engine

       These pages chronicle the construction of a home-built turbojet engine. The GR-7 is an experimental turbocharger jet engine that I have built for my personal education in 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
