GR-7 Experimental Turbo Jet Engine - Electric Starter Test

This video demonstrates the GR-7 electric starter system in operation. The GR-7 turbojet engine was built by Don Giandomenico as an educational tool used to further his understanding of gas turbine engines. The engine is based on an unmodified Cummins VT-50 14-liter diesel engine turbo. Coupled with a stainless combustor system (and several other support systems) the turbo is able to produce 50+ pounds of static reactive thrust. The starter system being shown features dual 3-phase brushless 500 watt drive motors that are coupled to the turbine with a retractable Bendix style drive coupling. The engine has since been modified with an electronic control unit that automatically drives the starter assembly during startup. Be sure to read more about this project at RCDON.COM.
