The High Temperature, High Speed Turbomachinery Fault
Simulator, previously known as the Heated Spinning Disk, was specifically
designed for NASA to develop new techniques for crack detection of
turbine blades and disks. It can operate up to 10,000 RPM at 1000° deg
F.
The machine
consists of an inverter driven induction motor, double belt drive,
rotating shaft with mandrel, disks, ceramic heaters, insulation jacket,
and heater
control with temperature sensor. The entire assembly is mounted to
a cast aluminum base plate fitted with stiffeners. Install
and operate the machine on a sturdy surface for best
operation.
