This original 1981 Gemini turbine rotor is the heart of a turbine auxiliary power unit. The blades are very thin and made from Titanium. This particular demonstration unit was assembled from scrap parts. Actual cost of a replacement for a unit like this is about $3,300.00. Donated by Janice Marshall of Solar Turbines.
